I just got my theater completed and am in the process of getting all of the audio tuned. The layout Dennis E. specc'd includes Triad Silver LCRs, Gold Surrounds, a CinemaPlus Silver sub and 3 SlimSubs.
Everything but the SlimSubs sounds great. The SlimSubs, however, make a popping, scratching sound nearly anytime bass comes out of them. Out of my 3 SlimSubs, one is very bad, the second is close to it. The third one is not too bad but it pops pretty regularly. The speakers sound like they are blown or being under driven. All are connected to individual RackAmp 350s. The SlimSub is selected in the RackAmp config. I have pulled the worst sub out of the column to make sure it was not an install issue. The sound clearly comes from behind the center of the driver. I have also swapped Amps and used the Amp from the least troublesome sub to the worst one with no change. I have tried lowering the gain as low as possible. The only way they don't sound bad is if they are so low that they are producing almost no bass. I cannot imagine I could have 3 bad subs...I have to be doing something wrong, but I am at a loss for what to try next.
/edit: Dennis has put in a call to Triad (on Christmas Eve no less....Dennis is awesome!). Triad is not too far away from my home so I've offered to take a speaker over there is they need to see one. We'll see. Still welcome suggestions if anyone has thoughts.
I spoke with Director Sales Bruce Franklin, and, apparently, a fix is in the works. It's also a considerable upgrade. Dennis Erskine is one of the top designers and integrators on Earth, and I'm sure he'll help, too.
I've mentioned a few times that the SlimSub (which is temporarily discontinued because of a supply issue) was conceived for distributed audio systems. It was designed to get some bass into a dining room, den, bedroom, where there was a pair of small speakers and more fullness was desired. I have suggested against using them in a home theater, unless they can be used in multiples, and grouped adjacent to each other and and near the floor so they couple. The less-than-4" depth mandates a 10" driver that won't move much air. They should be used when there's 4" of depth; for example, in an interior wall of a house. I'm sorry for the problems, but Bruce tells me there's a fix that should more than double your bass. Thanks for being civil, and not dumping on anyone in your post! Nobody likes broken "stuff."
