Model 3.
Thank you for your purchase of the NHT Model 3.3 Tower Loudspeaker. You have purchased a world-class loudspeaker that will provide you with many years of listening pleasure. We at NHT are proud of the Model 3.3 and we believe that you now own one of the best loudspeaker systems currently available. Please read through this Owner's Manual prior to installing your new speakers. The information provided will help you to obtain maximum performance from your audio system.
At NHT, we believe that a loudspeaker of this caliber should demand little compromise from the listener. That's why everything we know went into the 3.3...all our technology, our experience, our listening abilities. We admit we can't quite offer you perfection, but we can deliver sound beyond anything you have ever heard in your home.
fig. 1 To begin assembly, unpack the SpikeKit and inspect all the parts. The SpikeKit includes: (2) aluminum stabilizer bars, (4) aluminum cones, (4) stainless steel alien studs, (1) alien head wrench, (8) Phillips head machine screws and (4) rubber feet. Important: We recommend installing only the stabilizer bars until final placement of the speakers is obtained. This makes the speakers much easier to move.
3. Determine fine placement by moving the speakers inward or outward from each other 3" Move the 3.3's no more than 1/2" either toward or away from each other. Again make sure that the speakers are parallel to each other. Play the same three recordings again, listening for image focus, stage width and depth. Evaluate whether there is an improvement. If the overall performance is better, mark the position with a piece of masking tape, and continue moving the speakers in the same direction.
Model 3.3 loudspeaker system is compatible with virtually all quality amplifiers. Proper wiring of the speakers is essential to good sound. At a minimum, 14AWG speaker cable is recommended for runs of 10 feet or less, with heavier special purpose cable used for longer runs. For specialty cable considerations, consult your local authorized NHT retailer. For best results, use equal length runs of cable for the left and right speakers.
over-emphasize low frequencies. Additionally, the SA-3's low-pass crossover allows the user to adjust the rolloff of low frequencies to the subwoofer sections for further fine-tuning of the low bass and mid-bass regions. Note: It is very important that you remove the jumper straps when biamplifying or you will damage your amplifiers! Connect the top pair of binding posts with speaker cable from the main amplifier, and the bottom pair of binding posts with speaker cable from the second amplifier.
