Acoustic treatment

In the case of the much maligned CD not very much of the bass frequencies are coming through anyway so what’s the difference?

Has anyone ever tried having a single big sub and a few more smaller ones?  I'd think a single sub that goes to 20hz would be enough and then 3 smaller ones that only maybe go down to 30hz could be used to even out the response.  Locate the big one in the best spot for very deep bass and the other three can even out the response from 30-80hz.  There tends to be a huge price difference between subs that will go to 20hz vs 30.

Hello Mr. Rocket Science,

      True RS, most cds and vinyl recordings only contain summed mono bass from 20 to about 100 Hz but reproducing whatever bass there is on the source material with high fidelity is still important for an optimum listening experience.

Hello jon,
     Very good question.  I've never tried this myself but I don't believe there's any reason this wouldn't provide accurate, detailed, smooth and natural bass with deep bass extension down to 20 Hz.  I suspect, however, having only one sub extending down to 20 Hz might limit the power and impact heard and felt at that deep bass frequency.  But It may be possible to compensate by having the volume set higher on the sub that goes to 20 Hz or you could always use two and still be saving money, just a bit less.  
     You should also probably go look and hear some subs, 30 Hz sounds and feels quite deep and may be sufficient for some.

>>>I’m afraid you missed my point. The bass information’s there on the disc, and tons of it, it just isn’t being retrieved properly or completely - not by a long shot! Even when bass is mono it should have slam, go low in frequency and be articulate. It shouldn’t be wimpy, thin, rolled off or bland. As fate would have it the CD playback systems are plagued by a number of technical problems - even after all these years that prevent a lot of information from getting to the speakers. Primarily, scattered light and vibration of the CD itself, but also some other problems.
