I have attached some scans and info for you to look at.
All of my stuff is as new with very low hours of use. Sold as is, cash only, where is, as a matched set with no guarantee as they are electronics.
Sadly, I plan to get rid of the set as they are not being used and that is just not right. Everything is extremely heavy!! More pictures are available, along with manual and specs for everything. Zap an email. Below is a commentary with links on the DENON, THE NAKAMICHI AND THE POLKS.
"Matthew Polk's extraordinary new SDA Signature Reference System combines, for the first time, Polk's patented SDA TRUE STEREO technology with phase-coherent vertical line-source multiple driver topology to achieve new levels of state - of - the - art imaging, detail, coherence, dynamic range and bass reproduction.
Polk Audio is pleased to announce the introduction of an extraordinary new loudspeaker, the SDA Signature Reference System. The SDA - SRS will be the flagship model of Polk's highly successful SDA Series which will now be comprised of the SDA-1, SDA-2, SDA-CRS and the new SDA-SRS. This remarkable sounding, 3rd generation SDA speaker combines, for the first time, the latest refinements in Polk's exclusive and patented TRUE STEREO technology with time-compensated, phase coherent multiple driver vertical line-source topology. The result is a high efficiency system of awesome and seemingly limitless dynamic range and bass capability which reproduces music with a precise, lifelike, three dimensional soundstage which is unequalled.
Each 63.75" x 21 x 13 cabinet contains 8 Polk 6.5" trilaminate-polymer drivers, a planar 15" sub-bass radiator, 4 Polk 1" Silver Coil polyamide dome tweeters and an incredibly complex and sophisticated Isophase crossover system. One of the unique features of the crossover is the progressive variation of the high frequency high-pass circuitry which maintains virtual point source operation resulting in wide horizontal and vertical dispersion. Power handling is nominally rated at 1000 watts per channel, although the high efficiency of the system allows superb performance to be realized with even the most moderately powered receiver. Bass performance is, in a word, breathtaking. The use of 8 small active drivers coupled to the large 15" sub-bass radiator results in extraordinarily tight, quick and three dimensional mid and upper bass combined with low and sub-bass capabilities which are staggering (clean output at 25 Hz exceeds 100db!) An elaborate bracing system is employed resulting in a remarkably rigid cabinet which virtually eliminates colorations due to panel resonances. Separate inputs for high and low frequency sections of the system allows bi-wire or bi-amp operation without the need for a separate electronic crossover. The speakers are beautifully finished in oiled oak and walnut. "
