Selenium 18SWS1100 18" 1100W Subwoofer
Selenium 18SWS1100 18" 1100W Subwoofer is rated 3.0 out of 5 by 2.
Rated 4 out of 5 by from Excellant customer service....After the first experience with the SWS1100, we returned the affected units to Parts Express, and were pleased to be told that they would be sending us NEW replacements, AND even acknowledged that there WAS a minor manufacturing issue that had been resolved. I am VERY pleased to be able to tell you that these speakers ARE GREAT ! ! More than enough punch and frequency control to handle even the LOUDEST bands that we work with, but at the same time, smooth enough to handle the softest folk performer.....

Rated 2 out of 5 by from Fair price, but quality questionable...We bought 2 of these after much discussion with a co-worker who had some good luck with the 800 watt model. Initially the speakers seemed to work well, and appeared to handle the proclaimed power rating. However,after only 3 gigs, both of the voice coils tore loose from the cones at preciselythe point where the two are glued together.Although at lower power levels they work very well, with good clarity, and no discernable distortion, I honeslty do not believe that they can handle consistant 1000 watt running as advertised. Personal experience proves to me that the 800 watt version of this speaker is more reliable, and capable of handling more power without any failures.
