More Power or use subwoofer to boost bass for music

The question of the day which I believe George came close to asking you is what system was driving the 804’s when you were listening to them in the store? Also did you ask them to make sure the subwoofer was off when they demo’d the speaker’s? A lot of advise offered and some were excellent advice but start at the beginning of why you bought the speakers in the first place and what was driving them. You may be shocked on what you find out especially if you bought them from Best Buy Magnolia. Some of the sales force is not the best when it comes to operating their demo systems (Like turning off the subwoofer while the speakers are being demo’d. Just a thought.

Atmasphere:”But a DBA simply does it better, that’s all. You do the DBA first, **then** the bass traps (if needed), since the DBA is far more effective at sorting out bass problems.”


Hello atmasphere,

     Based on my experience using the Audio Kinesis Debra 4-sub DBA for the past 5years, I believe your advise is exactly correct. I didn’t plan on buying the DBA first and then add bass traps if needed, I just happened to inadvertently follow the advice you’d give 5 years later. I used my 4-sub DBA for abut 4 years with absolutely no room treatments except wall to wall carpeting. I currently use it in a fully GIK treated room per their suggested reasonably expensive room treatment plan following a free room analysis.      Their plan called for 2 of their fairly large TriTrap bass traps stacked in all 4 corners of my room, four 2’x2’x 5.5” thick bass trap wall panels. GIK’s plan also called for about sixteen 4’x2’ acoustic wall panels installed that are a combination of strategically placed absorption and diffusion panels.
     My main focus for having a professional room analysis done was to determine whether room treatments could make even further incremental improvements to my system’s midrange, treble and imaging quality. I was very concerned, however, with GIK’s suggestion of fairly extensive bass traps in my room. The bass quality in my room with the DBA in use was already, at that time, what I considered near state of the art without a single bass trap. I definitely wanted to avoid compromising my system’s excellent bass quality by deploying bass traps. After receiving assurances from GIK and A K’s Duke Lejeune that was traps would not negatively effect the DBA’s bass quality, l decided to include them all in my room treatment install.
     They were correct, I’ve noticed no negative effects in The DBA’s bass quality with a full complement of acoustic room treatments, including bass traps. I have noticed significant improvements in my system’s overall clarity, articulation and imaging, mainly in the midrange and treble range, I believe the bass traps helped extend this increase in overall clarity and detail down into the bass region but it’s difficult to claim with any certainty, since the bass was already very clear and detailed prior to adding the bass traps.      I can state with certainty that the added bass traps have had no negative effects on the DBA’s bass quality in my room. I actually think your previous comment, I believe I read on another thread, perfectly sums up my opinion on the DBA concept in actual application: “The DBA is an elegant bass solution”. Well stated and true.

I have had very good results with 2 REL T9i subs (that’s 9" plus passive radiators). I use the high level speaker outs and let REL’s internals do their magic. (On movies the REL "listens" to the Sub LFE output, but it’s not stereo.)
Very nice lower bass that enhances mid-range imaging. Flat to <25hz with few nodes as I roam about with my sound level meter, or just my ears. I use the old Stereo Review Test Record for node checking, then music.
Chest thumping impact on movies, but it’s the stereo listening that is really enhanced.
I followed the REL instructions for setup, which were unlike any technique I had used before. Then it’s just dialing in levels.
(Parasound A51, Dynaudio floorstanders + surounds. 18X35 room. I also have a window wall. Wood floors, area rugs and some minor wall treatments.)
Trying to EQ flat bass below 50hz on those B&W will drive them into directionality, if not distortion. Letting the REL’s do their internal crossover reduces overdriving the main speakers and they will be happier.
I drive 85dB as reference, without listener fatigue (the true measure of distortion(s)). That’s way too loud for an apartment.
Little subs, easy placement. Smaller REL’s in a small room would probably work well, too.
I have never liked big subs for stereo listening, although I have spent time with HSU and SVS. Great for "I have a SUB!" display to visitors but marginal for pure stereo. (Also had a Hartley 36" for fun.)

A lot of good answers. Sounds like a room problem. Two basic problems, speakers not coupling to room walls or bass cancelation based on room size relative to listening area. If moving your speakers don't do the trick, then try adding a sub. Check dealer for return policy. A single sub should provide enough punch and accuracy to satisfy most tastes.
