The NHT Classic Four is a formidable tower style loudspeaker. While the Classic Four looks like a tower, it is really a three-way bookshelf speaker (the Classic Three) sitting on it's own, integrated subwoofer stand. This design provides the detailed imaging, delicious midrange and natural sound-staging of a fine bookshelf speaker with the bass and dynamics you'd expect from a first class tower speaker. Provided you use a quality receiver or amplifier, the Four can fill a medium to large room with ease with rich, full-range sound. The Classic Four is perfectly at home in a high-quality home theater or in a carefully configured reference music playback system.
Acoustic Suspension Hybrid: The Classic Four is an acoustic suspension design where it really counts - the critical midrange frequency range. In this section of the speaker, we use the trapped air (natures most perfect spring) in the upper sub-enclosure to control and damp the mid-woofer cone motion. This ensures the Classic Four delivers smooth, natural midrange with low distortion along and high power handling. This sealed upper section blends perfectly with the built-in, acoustically isolated, side mounted 10" subwoofer that provides usable in-room bass response to a remarkable 24Hz. This hybrid design allow the speaker to to deliver accurate midrange sonics you'd expect from a high end monitor speaker with the bass and dynamics that a larger floor standing speaker can provide. In addition, the subwoofer section may be bi-amplified for even more spectacular results.
Four-Way: The Classic Four is a 4-way design (unusual as most tower speakers in this price range are 3-way designs) using a custom designed 10" aluminum cone subwoofer which is mounted on the lower side of the cabinet, on a wide baffle - an acoustic environment well suited for low frequencies. The mid and high-frequency drivers are located proper acoustical environment as well - located on the narrow front baffle like a fine bookshelf speaker on a stand. The driver complement starts with a 6.5” anodized aluminum cone "lower" midrange driver set in a low resonance BMC (Bulk Moulding Compound) frame. The "upper" midrange and tweeter are located on NHT’s proprietary tweeter/midrange plate we call the "Pod". The Pod contains a 3/4" dome tweeter and 2" dome midrange - both with anodized aluminum diaphragms with powerful, compact neodymium magnets. This Pod keeps the drivers in close proximity to each other (and with the lower midrange) which help them act more like 1 wide range driver but with low distortion benefits of a multi-driver system. This combination of quality components, thoughtfully placed in acoustically beneficial location insure the Classic Four will deliver the goods from room to room to room.
The Cabinet: The Four is made with CNC milled and laminated ¾” and 1” dense fiberboard with extensive internal bracing and baffling for rigidity which helps reduce unwanted resonances. The front baffle itself is almost 1.5" thick! Along with the internal braces, the Four's cabinet has separate isolated sub-enclosures for the mid/high frequency drivers and subwoofer sections. The the top front of the Four has variable radiuses flanking the Pod which help to randomize the upper frequency diffraction effects. The cabinet's curved top, gentle edge radiuses and hand-rubbed, high-gloss piano-black finish lend a sense of timelessness to its visual aspect. Classic Three's are sold and packaged individually as left or right side speakers. Included are 2-piece BMC formed stabilizer wings with threaded inserts for included carpet spikes. Rubber pads are included for hard flooring.
Adding a Subwoofer: The Classic Four is a full range speaker making a subwoofer completely optional. Adding a NHT Classic series subwoofer to a pair of Classic Fours will however allow the Fours to have application flexibility. For example, Fours can be ran solo, full-range for excellent stereo music performance while allowing separate subwoofer(s) to improve system dynamics and lower total system distortion in a home theater system to levels usually associated with amplifier specifications. If you are considering a subwoofer, we recommend one or two Classic B-12d's as the perfect match followed by one or two Classic B-10d.
Mixing and Matching: Building a home theater system? All NHT speakers are designed and voiced with the same design goals so you have the freedom to use any of our Classic Series center channel speaker. That said, corner us in a dark bar and well likely recommend the Classic ThreeC center channel speaker as the perfect match followed closely by the Classic TwoC. Rear speakers? Again, a perfect match would be floor or wall mounted Classic Threes for surround and back channels but many people may opt for the Classic Absolute Zero's in Black or White because of their compact size (or a combination of both).
The Company: Let’s not forget that you’re buying NHT speakers and that means all sorts of things. It means you care about getting the best speaker value for your hard earned money. It means and you care about quality craftsmanship and high-end performance. It means you’re ready to join our family of fanatics who love music, movies and the best gear that produces them.
