Which component upgrade will produce more BASS?

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.

Dear Shardone/Ajahu: I'm with both of you about active speakers, I like the whole idea. I never own/owned active speakers but in some ways I was on part of that concept when I was triamp/tetraamp my speakers.

The active subwoofers integration in full stereo way is part of that active speaker concept that has several advantages: almost no cables and each amplifier/speaker driver specifically matched for its own each driver characteristics are two subjects in active systems that means lower distortions that a non-active speaker can/could match, lower distortions means more " music " and means a step further on the music enjoyment.
I know we can go on on the active speaker concept, I heard some systems about: ATC, Pass, Meridian, etc, etc . each one sounds different and like always room/system dependent.

Over the years I try to go lowering my audio system's distortions ( any kind/everywhere ) and I like what I have even with more distortions/colorations that in a full active system but nothing is perfect and all of us have to make some system performance choices that means: trade-offs, I think that my overall trade-offs put me near to the music.
I love the active speaker concept but what I heard through the ones I name here are good alternatives but don't fulfill my quality system performance priorities.

IMHO, I think that the concept on active speakers is a great one but it is more easy to " accept/like " in subwoofers than in other frequency ranges where all of us are more sensitive and where belongs our music-sound reproduction priorities because it is not only that the driver/amplifier is totally matched but that that driver and that amplifier meet our individual/subjective expectatives and this issue ( I think ) is ( between other things ) what till today preclude a more " normal/massive " marketing on that active speakers where you not only " married " with a speaker but with an amplifier too.

Ajahu, IMHO nothing comes for free: we have to make our job and yes I agree it is a hard work and not an easy one: I take several months before the subwoofers integration in my system goes seamless but it is worht of it.

Regards and enjoy the music.

I just wanted to thank everyone for their input. To start I'll first work on placement of the Blues. If that doesn't help a subwoofer would definitely be considered. Onhwy61 wanted to know the placement of my equipment. On the 10ft.wall centered is all the components on their own target wall mounted shelves. Under each component are 2in. maple platforms. The Pass amp sits on a 2in maple platform with brass footers sitting right on the carpeted floor. My Blues are positioned 32in. from the short 10ft wall(same wall as my components) to the rear of the speakers. The side mounted woofers are facing outward about 16in. from the long 20ft side walls. I hope I explained that well. Shadorne actually nailed it on the head what sound I'm looking for. Its not the boomy bass but the fast,punchy bass. An example is Paul McCartney's bass guitar work on alot of later recorded beatles albums. Or the drummers bass drum kicker. Again thanks Ziggy

Ziggy333a : I wish you the best on the quest to Mo'Bass. While your at that, persuse the video I mentioned on AG. Steel to Brass not a "new" idea but its certianly over-looked, regardless what option you chose, the change-over is always a possibilty.
