Rotel RSX-1562 SURROUND SOUND RECEIVER

Category:
Model:	RSX-1562
Title:	7.1 Channel Surround-Sound Receiver

The RSX-1562 builds upon the excellence established by its highly acclaimed predecessor, the RSX-1560, but with the addition of new, improved circuitry and technologies such as HDMI® 1.4 with 3D. In addition, the advent of so many video sources such as a cable or satellite box, DVRs, DVD players, and WiFi or Ethernet audio / video feeds from devices such as Apple TV® and Roku® etc., have necessitated adding more HDMI inputs. The RSX-1562 now has six HDMI 1.4 inputs and two HDMI 1.4 outputs, one with an Audio Return Channel (ARC). The ARC in HDMI 1.4 enables a TV via a single HDMI cable, to send audio data “upstream” to an A/V receiver or surround audio controller, increasing user flexibility and eliminating the need for any separate S/PDIF audio connection.

PSB Imagine T2 Speaker System

the standard-issue, black-grilled, plain-Jane, rectangular coffins for which significant others might grudgingly give up floor space in return for other concessions. After all, pocket-protector-wearing, slide-rule-swinging, techno-geek research types aren’t known for their sense of fashion.The Imagine series speakers’ looks are far from that, however, because PSB turned to David Farrage and his New York design firm, DF-ID, to provide the industrial design.

I’ve never met Farrage, but based on the Imagine series speakers and the work he’s done for other clients (including Sony, Samsonite, NAD, Lamborghini, and Movado), I’m quite certain a pocket protector is not part of his wardrobe. Farrage deserves many kudos for the organic beauty of the gentle curves and the finely executed details of the Imagine speakers. The Imagine T2 tower speakers, for example, don’t unabashedly draw attention to themselves  as do, for example, some Sonus faber or Focal speakers. Nor are they a more subtle statement, such as the look of the narrow aluminum cabinets of Definitive Technology’s Mythos speakers. Instead, the visuals of PSB’s Imagine speakers fall somewhere in between—for the most part disappearing into the room but, upon closer inspection, revealing an understated beauty and elegance.

The Imagine T2 ($3,500 per pair) is the latest addition to—and the new flagship speaker of—PSB’s small group of Imagine speakers, which includes the smaller Imagine T tower, two pair of monitor speakers, two center channels, and a unique tri-mode surround speaker. For this review, PSB included the larger Imagine C center ($850) and a pair of the tri-mode Imagine S surround speakers ($1,300 per pair). All the speakers share the inspired design elements, as well as the same family of drivers.
The Imagine T2 is tall (a little more than 40 inches) and slender (a bit more than 8 inches at its widest point) with the sides sloping from the curved, 2-inch-thick, MDF front baffle toward a narrow, rounded back. As far as I could tell, the only flat surface is found on the bottom of the cabinet. Greg Stidsen, PSB’s director of technology and product planning, explained that the cabinets start out as seven layers of thin MDF that are form-fit and pressed into shape. The cabinets are then placed inside the industrial equivalent of the microwave oven on your kitchen counter to cure the glue between each layer. Then a CNC machine drills the holes for the drivers, and the cabinet’s wood veneers are individually hand-sanded and finished. The result is an elegant, well-proportioned tower that, even when toed in, shows a thin outline of wood on either side of the black grille when viewed from the main seating position. The tower rests on four round feet located at the bottom corners of the cabinet with a tap in each that accepts either the included spikes or rubber pads.

baffle, sloping sides, and the same 1-inch titanium-dome tweeter. In this case, though, the tweeter is centered between two 5.25-inch drivers. The Imagine C comes with a port plug, although there’s only one port to potentially seal. Since the cabinet is curved on every side, PSB includes a short, black rubber bar that you can place under the Imagine C to position it at the correct angle. The dense rubber material holds the heavy (26.8-pound) speaker securely in place and helps to reduce vibrations that might transfer to whatever the speaker is sitting on top of.

The Imagine S surround speakers were smaller than I expected based on the dimensions of other high-performance bipole/dipole surround speakers I’ve encountered in the past. The surface-mounted Imagine S speakers take up less than 11 x 13 inches of wall space and extend only a tad more than 7 inches into the room. They’re not quite as elegant as the Imagine T2 and Imagine C, but their curved front and prominent center strip of wood definitely identify them as part of the Imagine family while still allowing them to remain unobtrusive in most rooms. The Imagine S speakers aren’t ported, and they include 1-inch tweeters and 5.25-inch woofers. In this case, one tweeter/woofer combo fires forward, and the other fires rearward—but the Imagine S isn’t your standard bipole or dipole surround speaker.

Even without the aid of the SubSeries 300, the Imagine T2s’ two-channel musical performance was absolutely stellar. They had that wonderful character of having almost no character—sonically, there’s nothing that draws specific attention to the speaker. The placement of the tweeter below the midrange puts it at seated ear level, which is generally the goal. In this case, I found the soundstage’s plane to be lower than is typical. In other words, I find that other speakers tend to place vocals slightly above the level of my ears. With the T2s, Bonnie Raitt’s voice on “Take My Love With You” from the new Slipstream CD seemed to come from a position directly even with, or perhaps just below, my ears in front of me. Especially impressive was the smooth transition from driver to driver, as well as the extremely wide soundstage the T2s produced. On “Until You Remember” from the Tedeschi Trucks Band’s Revelator disc, the horns’ plaintive notes at the beginning of the song were so smooth, it felt like the T2s were slowly pouring pure New Orleanian sadness into the room. That was followed by the tight plucking of guitar strings to the left of center, and, once Tedeschi’s dead-centered voice was joined by the remainder of the band, each instrument was clearly defined and placed across a wide soundstage.

The Imagine T2 system is splendidly seductive. The graceful curves coyly play with your eyes without demanding constant attention. In the same way, the Imagine T2’s sound is beguilingly smooth and natural; and those alluring sonic qualities extend to the Imagine C center and Imagine S surrounds—and the SubSeries 300—when they’re brought together in one room. Even though it’s composed of six individual boxes, the system is absolutely superb at working together as seamlessly as if it were one big speaker—or, perhaps, no speaker at all. Even if the Imagine T2 system were pink and yellow with a purple-fringed grille cloth, I’d still have to recommend it because it sounds so damn good. Fortunately, it’s a beautiful and elegantly designed piece of work. If this is what comes from living in an anechoic chamber for a good part of your life, then so be it.by darryl wilkinson

 

Definitive Technology BP-8060ST

Bipolar technology (speakers on front and back of enclosure) for huge room-filling sound for every listener in the room

Built-in 300 Watt powered subwoofer delivers massive bass; eliminates need for separate subwoofer

Second generation BDSS high-definition drivers for life-like tonal balance, superb intelligibility and broad dispersion

Slim enclosure takes up minimal floor space (1 sq. foot)

A Legend Reborn
Definitive Technology's first product in 1990 was a bipolar tower loudspeaker. The BP10 was the first step in building the company that stands 20 years later as the best selling and most honored brand of audiophile-grade loudspeakers in the USA. Later Definitive pioneered the concept of "powered towers" by incorporating powered subwoofers into Bipolar floor-standing speakers and dubbed them "SuperTowers." The BP-8060ST is a third generation BP SuperTower and makes use of our most advanced technologies, including a new patent-pending approach to bipolar speaker design called Forward Focused Bipolar Array, Digital Signal Processing amplifier and our patented BDSS driver technology. The BP-8060ST SuperTower is the crowning achievement of over 20 years of research and development to create the perfect balance of style, convenience, and most of all performance in a floor-standing loudspeaker.
The Most Advanced Technologies for the Most Advanced Performance
If you love great sound you must experience Definitive's BP-8060ST Bipolar SuperTower. Its combination of Forward Focused Bipolar Array™ technology (for rich life-like, room-filling, three-dimensional sound), built-in SuperCube® technology powered subwoofers (for lightning-fast, earthshaking bass), and our latest generation patented Balanced Double Surround System (BDSS) midrange drivers, all housed in a rock-solid attractive enclosure, delivers unsurpassed sonic performance.

Bipolar technology creates a huge, three-dimensional soundstage

for every listener in the room

Bipolar Technology Brings Performances to Life in Your Home
Many experts and in-the-know listeners agree that bipolar speakers are superior for both music and home theater. With bipolar speaker technology each speaker incorporates two sets of drivers, one facing forward and the other facing to the rear so that the speakers radiate sound both forward and rearward exactly as sound is produced in real life. Forward Focused Bipolar Array™ technology is Definitive's patent-pending improvement to our original Bipolar designs. This new ground-breaking technology combines the huge life-like imaging benefits of bipolar design with improved pinpoint localization of soloists, greater placement flexibility, and superior intelligibility.
The sonic benefits you hear are dramatic! This unique technology provides you with a lifelike balance of early-arrival sound from the front facing drivers, which provides focus, clarity and location data, and reflected delayed sound from the rear drivers which conveys the lush three-dimensional soundstage of a live music or cinematic performance. This combination creates a huge soundfield which is rich, warm, ultra clear and vibrantly alive for every listener in your room. Most importantly, Definitive's bipolar speakers make the walls of your room seem to disappear transporting you into the sound space of the recoded event. They will literally bring your music and movies to life in your home. One listen and you can never go back to conventional speakers again!
The Subwoofer System Will Rock Your World
Each BP-8060ST combines a built-in 10" subwoofer driven by a 300-Watt class D amplifier and two pressure-coupled 10" Low Bass radiators for 29% more surface area than a single 15" woofer but with better control, speed and detail than a single big woofer could ever deliver. The built-in powered subwoofers achieve dramatically better blending, integration and timbre accuracy than could ever be achieved with separate subs.
The brawny 300 Watt Class D amplifier features an integrated Digital Signal Processor (DSP) – in essence a mini computer – that equalizes the woofer system to extend and smooth the bass response, provides a phase coherent crossover to perfectly blend the subwoofer system with the midrange arrays for seamless high performance. Digital protection systems tightly monitor and control the woofer system to prevent distortion and woofer damage at ultra-high volume levels. The bottom line is the BP-8060ST's bass will rock your world like no other speaker anywhere near its price and size.
Why Built-In Powered Subwoofers Are Better Than Separate Subs
Besides eliminating the need for a floor space-hogging separate subwoofer, integrated subs offer dramatic performance benefits. First is the obvious benefit that you'll have two subwoofers in the room instead of just one for simply more bass output. Second, two subwoofers in the room reduce "standing wave" room resonances that create bass dead zones in the room. With two ST-8060STs you'll enjoy high impact bass throughout the room.

Most importantly the subwoofers are perfectly integrated with the mid/high section. Audiophiles often spend hours moving and adjusting their subwoofers' crossover and phase controls in pursuit of perfect subwoofer to main speaker "blending." With the BP-8060ST you won't have to go through that kind of hassle to get great sound. Definitive's engineers have perfectly adjusted the crossover and phase to achieve seamless blending and life-like sound. All you have to

Patented Technology Delivers High Definition Mids and Highs Each BP-8060ST features a D'Appolito front array consisting of two cast-basket 4-1/2" second generation BDSS midrange drivers surrounding a 1" pure aluminum dome tweeter housed in an acoustically isolated sealed enclosure. The drivers feature Definitive's patented Balanced Double Surround System (BDSS) technology that supports the speaker cone at both the inner and outer edges allowing longer, more linear excursion for greater clarity and finely textured inner detail. A new patent pending Linear Response Waveguide™ smoothes off-axis frequency response and disperses sound over a wider area for crystal clear intelligibility for every listener in the room. The tweeter is a pure aluminum dome, which has been heat-treated to relax the crystal structure and then coated with a ceramic to produce extended highs that reveal nuance and shimmer without a trace of edginess.
The rear array uses a single identical BDSS driver and the same 1" aluminum dome tweeter as used in the front array. Like the front array the rear array is housed in a separate sealed MDF enclosure to isolate the midrange drivers from the woofers' influence.
Slim Elegant Styling with Rambo-Like Brawn
All the driver and electronics technology in the world would be wasted if housed in a resonance-prone box. We devoted as much Design and Engineering attention to the styling and construction of the 8060's enclosure as any other part of its design. The tapered front of the enclosure serves to make it appear slimmer while also enhancing sound quality by minimizing cabinet diffraction distortion. The decorative high gloss end cap and bottom panel add elegance to the matte black tower the way satin piping adds dash to a tuxedo. Each BP-8060ST occupies a mere 1 square foot of floor-space (including stabilizer feet) leaving plenty of room for furnishings.
But the enclosure's most important job is to be totally inert and resonance free so as not to color the sound. And that's just we did in engineering the BP enclosures. Wherever a driver is attached to the cabinet we placed a second layer of heavy MDF (a low resonance wood composite material) to prevent the drivers from imparting vibration to the rest of the enclosure. The sealed midrange enclosures also serve to provide bracing for the side walls while MDF cross braces near the woofer further stiffen the system. Tap on the side panels of a BP enclosure to hear the solid "thud" of a solid, well-damped cabinet instead of the hollow ring of a poorly constructed speaker. NOTE: the high gloss polymer composite end-cap is a decorative element; it is not part of the acoustical system.
The Proof is in the Listening
This extraordinary speaker sets a new reference standard for high-accuracy loudspeakers in its class and achieves equally superb performance with both music and movies. The BP-8060ST reproduces a silky smooth, incredibly detailed sonic image at lifelike volume levels with a sense of ease which is truly remarkable.
Movies and music are reproduced with unequaled purity, transparency and lifelike realism. These elegant, slender towers seem to disappear in a huge natural soundstage which extends in a three-dimensional arc beyond the speakers with front to back depth which recreates the illusion of live music or cinematic action being performed live in your room. This combination of high resolution, magnificent sound-staging awesome bass and explosive impact envelops you in the ultimate listening experience.
Now that you're thoroughly impressed with the technology and passion we've poured into every BP series product it is time to find a stocking dealer near you to audition this remarkable achievement of art and science.
