NoiseSolution Posted March 2, 2018 Share Posted March 2, 2018 (edited) Hello folks, again new the forum, I was at a flea market and came across a sub-woofer by Definitive Technologies ProSub 800 cube, to my surprise it was acoustic suspension with pressure coupled passive radiator, I have a few other subs but for its size both being 8 inch and very compact in design, retails for $399 and got this for $75, rated at a true 20hz this was a great find. Does anyone own this type of sub and if they do, please let me know if you are as satisfied as I am with this sub. I will be using this sub in the bedroom because of its small footprint. I was surprised the bass radiator didn't have standing waves that would muddy the very lowest frequencies.

CECAA850 Posted March 2, 2018 Share Posted March 2, 2018 The passive radiator acts the same as a port. Quote Link to comment Share on other sites More sharing options...
NoiseSolution Posted March 3, 2018 Author Share Posted March 3, 2018 Thanks for the info, first time dealing with passive radiators except for an old pair of Polk Audio speakers, they use an 8 inch driver with 12 inch passive radiators but they seem to produce those standing waves that muddy around the 100 hertz range Quote Link to comment Share on other sites More sharing options...
K5SS Posted March 4, 2018 Share Posted March 4, 2018 I have owned about 5 DT subwoofers over the years, all the way up to the SuperCube Reference. DT inflates their performance numbers quite a bit, and their online reputation is lower than it should be in the audio world. With th all that said, I have enjoyed every DT subwoofer I have ever owned. Their small footprint and big performance are characteristics I usually look for. Great pickup OP! 1 Quote Link to comment Share on other sites More sharing options...
NoiseSolution Posted March 5, 2018 Author Share Posted March 5, 2018 Thanks for the reply, like you probably know I would never pay the $399 retail price for this cube. The performance is awesome its just this sub is def made for small rooms. I currently have it hooked up in a large room and it does a fine job, I will be looking for larger woofer sub, I have been switching the satellites up from basic Klipsch R-15 bookshelves, Definitive Technologies Pro Monitor 800's, a set of Bose 301 series 5's ,it seems I HAVE to use it if I want too or not with the Klipsch R-26 towers, I got a great deal at a swap meet for these towers. but I am not pleased with their performance at all and could see why the dealer parted with them for a set of TLX-151 towers, made in like 2000 and a set of Bose 301 series 5 speakers. I think I got lost in the bells and whistles of exotic materials and tractix horns. I have a set of JBL Arena 180, direct comparison speakers, size and performance basically the same, the JBL's soar over these R-26 towers. I just thought at this price point I could hook these up stand alone and listen to any progressive rock song and get superb performance, these fall utterly short of the mark.
