The NSMT 20M In-wall Speaker
The NSMT Model IW6.5 ambient sound in-wall monitor is based on the design of the highly acclaimed Mastering Series 20M monitor. It is designed to produce seamless response from 28 Hz to 20,000 Hz +/- 3 dB. This bass response is considerably lower than the THX required response for subwoofer. Hence a subwoofer may be optional.
The !W6.5 (20M) in-wall is handcrafted in-house by NSMT Loudspeakers to give you the performance and imaging you expect from one of our high quality minimonitors. The driver complement is a concentric driver array that is time coherent and a true point source which means both the high frequencies produced by the tweeter and the mid and and low frequencies produced by the woofer reach your ear at the same time. Even when the sound is reflected off the walls you don't get two separate reflected pathways of the sound (one for highs and one for lows) reaching your ear at different times (which muddies the sound), but a single coherent waveform. The time coherent, point source design also means the sweet spot is not limited to a narrow band in the middle of the room because no matter where you sit you are equidistant from the tweeter and woofer of each speaker.
Moreover because the driver uses the wall cavity to generate subwoofer bass response, the entire response of the speaker from 28 Hz to 20,000 Hz is linear and continuous without the phase abnormalities and integration problems that often plague some in-wall subwoofer systems and cause suck outs and inconsistencies in the distribution of sound throughout the room. If you want the refined performance of the finest monitor loudspeakers, few in-walls and subwoofer combos come close to the performance of the IW6.5-20M in-wall.
