from AppealI cannot measure the output response, specificly the bass extension. All I can do, is use my ear, next to the Dayton 7" aluminum woofer, costing about 1/2. Comparatively...the Peerless driver has clear and detailed reproduction, and it seems, in the proper cabinet has very significant bass output, however, in my test cabinets, the projection is a bit deceiving; I have no qualm that a speaker designed with this driver can be a very serious contender in a commercial endeavor. I paired the Peerless nomex driver with a ribbon tweeter with a simple 6db 3.3uf crossover. The nomex woofer extends into the crossover frequency and the natural mechanical rolloff created a very good working crossover into the ribbon. I believe the parameters of this driver are "Remarkable". My 4.5 on the scale for 'features' was given only since there is no bucking magnet mounted, and in the current speaker market, basing a tower speaker on this driver requires keeping it away from CRT. Alternately, if the driver is high in the cabinet the weight toward the top of the cabinet is lower without a bucking magnet, and the stability of a cabinet with a small footprint is greater with a low center of gravity. 'Entropy' on my design sheets is a 3' tall 8.2 x 8.2" of such design, using the Vas of the driver with additional port full-length resonance 20hz. 'Entropy' uses a pile of scrap steel in the bottom, capped with resin to solidly couple the tower to the floor. The Peerless driver in my 5-way configuration coupled with a ribbon tweeter created a seriously large soundstage.

from Look at the spec sheet, what a nice FR!This is the woofer used in the "Elsinore" speaker (which I haven't heard, but I'd like to). It's well constructed, has a shorting ring, very open on the back side (NICE cast frame). If you went some other high $ woofer ($100 +) don't assume you'll end up with a better speaker. Cost is not always equal to sound quality. Low distortion, decent excursion and efficiency, moderate box size - all around great woofer.
