"Home Theater System of the Year Award" from The Perfect Vision
"Scary Good" Floorstander with 10" Side-Sub
For full-frequency home theater excitement from smooth treble to the lowest bass, you can't beat the new NHT Classic Four. It's a floorstanding version of the Classic Three, which NHT says is the best bookshelf speaker that the company has ever produced. A bass enhancing 'tower speaker' cabinet gets a huge side-firing 10" passive subwoofer driver for the kind of music low frequency response you usually can't get without a dedicated powered subwoofer.
"Few systems this price can match the Classics' openness, detail, and three-dimensionality -- qualities guaranteed to enhance your enjoyment of music and films," reports Chris Martens in his December 2006 The Perfect Vision review of NHT's Classic Three, Four, and Three C center speakers. "The Classics' imaging is just scary good."
The Perfect Vision magazine liked the NHT so well, that it gave its "Home Theater System of the Year Award" to the Classic Four, Classic Three, and Classic Three C speakers.
"The room-shaking abilities of the Classic Four's 10-inch woofer appeared to extend well into the mi-30-hertz range in my large home theater," observes Steve Guttenberg in the April 2007 issue of Home Theater magazine. "I'd recommend starting out subwooferless, and then, if you want a little extra kick, biamp the Classic Fours with NHT's X1 crossover ($350) and A1 outboard amp ($400)."
The Classic Four also features a newly developed 6.5" aluminum cone bass driver and NHT's exclusive midrange / tweeter assembly.
"Spectacular Imaging"
"The imaging is spectacular in its scope and room-filling dimensions," marvels Steve Guttenberg in Home Theater. "The Classic speakers' image height, width, and depth approach what I've heard from the better electrostatic speakers. But electrostatics can't generally deliver the Classic Fours' dynamics and room-shaking bass."
The Classic Four works beautifully right out of the box with your existing home theater multi-channel amp or receiver. For even better performance, the Classic Four can be bi-amplified with NHT's optional A1 amplifier and X2 crossover.
Graceful Sound-Enhancing Cabinets
While the Classic series cabinets are beautiful, their shape is all about the business of making great sound. The graceful cabinets place every driver into a consistent predictable acoustical environment. For example, variable radius edges on the cabinet sides randomize diffraction from the midrange and tweeter drivers, aiding the speakers' dispersion of midrange and high-frequency sounds. Careful placement of the Four's built-in subwoofer guarantees tremendous deep bass response in almost any room.
Creating a Large Listening Area
By using two low distortion drivers mounted close together on a single plate, NHT is able to produce a speaker with a large listening area, lower distortion, and higher power handling than typical two-way designs.
All of the woofers in the Classic line feature frames made from BMC (Bulk Molding Compound). Usually a designer has to choose between inexpensive, mechanically sound materials such as ABS plastic and stamped steel, or expensive materials such as cast aluminum or magnesium that are ideal acoustically and mechanically. BMC delivers the best of both worlds. It is a cost effective material that is immensely stiff and easily shaped into acoustically ideal shapes.
Beautiful Environmentally Friendly Cabinet
The cabinet is made with MDF, a board manufactured primarily of wood residues from the production of lumber and plywood with a low percentage of virgin tree wood. NHT finishes them with seven coats of hand-finished polyurethane applied in a "solid particle" method that's safe for the environment. This finish is then sealed with two coats of automotive grade clear-coat to protect the finish. By avoiding exotic wood veneers, and using materials such as MDF, NHT doesn't sacrifice scarce natural resources to make acoustically sound furniture grade cabinets. |
