improving bass on large floorstanders....


I have some 3 way tower speakers that could use some bass improvement...however...if the results are minimal...i probably will pass...at any rate...would the addition of floor spikes or possibly a cable change be the answer?...I am looking for tighter, leaner bass if possible...thinking entry DH labs or Nordost...at any rates...what has worked/ not worked for others?

And how can anyone recommend spikes when the OP hasn't even mentioned the floor the speakers are sitting on.
Nor has he mentioned what speakers he's using. That might help also.

what are some affordable bass traps?
Take your original tower speaker boxes, stuff them with wadded up newspaper, and stick them in the corners. That's the most affordable version I know of. I first read that recommendation in a magazine interview with the guys who founded and run Shakti. It's what I use in my HT 7.2 rig with dual-ported Mirage M5si's. Cleaned up the bass quite noticeably.
If you're really interested in hearing clean bass, get hold of any Audyssey equipped pre-pro or AVR. Overall, it may or may not be your cup of tea, but it will almost certainly improve bass performance in a startling way.
