Which component upgrade will produce more BASS?

I suspect deep bass is not really the issue. Ziggy is probably lacking energy in the 60Hz to 200Hz region which is probably due to room/speaker/listener placement issues. It would help if Ziggy would describe his equipment placement within the room.

Dear Ziggy333a: IMHO if you want to improve the overall quality performance on your audio system including BASS then please take the time to read this about:

Rauliruegas,

Good link. I did not read the entire thread but I realize that I do share your views about the terrible amounts of distortion from typical bass in both subwoofers and most speakers. This is why I recommend large woofers with large motors with large diameter voice coils working with a short coil in a large magnetic gap (the most linear type of woofer). I did not mention it above but the vast majority of woofers are the lower cost small diameter long voice coil in a short gap and which means they are pretty much non linear over their entire operating range and resulting in highish amounts of IMD distortion and harmonic distortion.

However, I think this goes far beyond the simple request of Ziggy and don't want to divert us from that goal but nevertheless I agree with you wholeheartedly.

Use of subwoofer is a good idea. One of the way to build a good sounding system is the employment of subwoofer. But still there is a problem: integration into system, which already has coloration which the owner do not like. That is a difficult task for most people. In general, I think, that most home systems are just sounding crap. Especially, if one takes into the cost of the system. Most people following the fashion of particularisation through building up the system from specialised and dedicated pieces. It is just extremely difficult to build up a naturally sounding system. Most so called high-end systems have a very owner specific coloration, with which the owner itself is not completely happy. Hence the constant changes. My personal experience is that the best way to avoid the possible merry-go-round is to go for as simple system as possible. In this term, given the extreme importance of loudspeaker-amplifier link, the best way is an active loudspeaker. It is just amazing how easier to get right the sound of with an active loudspeaker, and how much once that is right you can get rid off spending on such complementary colouring things like cables, etc.
