What is the most dramatic way of increasing a speaker's Bass and Low mid?

Thanks Bob- Could you tell me please how many db's of extra Bass, Bell or Shelf, and at which Frequency center point or Corner(depends on curve type)?


Thanks!

dumbeat,
You are asking for actual objective evidence rather than anecdote.  That is verboten in the realm of cables ;-)
Your experience in taking off the footers and leaving your speakers flush on the floor was similar to my own.  I tried some Isoacoustics products, and also spikes, under my speakers and they sounded better (IMO), especially in terms of tight bass response, sitting on my rug without any footers.

So you liked the speaker flush on the floor or with spikes at the end or isoacoustics? its not clear; And What was the difference you heard?
Flush on floor=more low, Spikes= Tight? not sure what that means... "Less Low mid" tight?
Thanks,

I prefer them flush on the floor - no spikes, no rubber footers (e.g. no Isoacoustics). At least in my case, in my room, my Thiel 2.7 speakers just seem to have the most bass grip without being raised on anything.

They sit on a rug, over hard wood floors.

When placed on the isoacoustic products, the sound generally seemed to lose tightness and brilliance, even in the mids, but I noticed it most in the bass range, probably from 70Hz or so and down to 40 or a bit below, where bass guitar etc lost focus and density, and seemed to have a sense of overhang and looseness around the bottom.


The entire sound changed, though, to a darker, lusher, less focused presentation, which I did not prefer.

dgarretson, as usual your eloquent explanation is thorough and insightful. Nice to hear from you again! 

Prof, we may be talking past each other on your first rebuttal; I'm not saying cables have little influence literally on the sound in a studio. I am saying that the fantastic resources of the studio to manipulate the sound do not transfer, i.e. presence of mixer, to the home. The environments and tools to contour sound are radically different. In the home environment cables take on a much more important role in shaping the sound. 

As to your second argument, my experience with dozens of brands and many looms of cables is fundamentally different, which leads to my statement about sound quality of a system and cables. Consistently use of lower end, less expensive, etc. cables (and, yes, pro oriented such as Mogami) have been mediocre by a great deal perceptually. I just recently once again had that experience as I was testing out three different sets of Y cables, and the worst was the pro/musician brand, while the best (clearly audible) was the specialty one from Audio Sensibility.  It seems we will simply disagree on this topic. I would suggest that your perspective is a disservice to audiophiles if you wish to make it a declaration. I can add the phrase, "... in my experience," and then we are not pretending we have absolute knowledge. We  are at this point at an impasse, however I suspect we will continue to be cordial. :) 

dumbeat, your prodigious skills and knowledge regarding studio does not all translate directly to home audio - or else you wouldn't be asking for a relatively simple fix for an audiophile in your original post. Many of those with decades of experience in home audio would know how, and successfully obtain the result they wanted.

Note this; home audio is not as much a science as in the studio, but more so an art, due to the difference in equipment available. I get what you declared without substantiation in regard to cables being the last 1%, but take way all the toys of the studio and now what have you to contour sound? The very recommendations in regard to placement, room prep and cables that the experienced audiophiles are recommending.

Bill Dudleston of Legacy Audio does work inside and outside the studio. As an experiment he humored me in a review of his Legacy Whisper speaker; he upgraded the internal wiring and caps at my request in an effort to see what improvement might result. He had doubts, but afterward measured a 2 dB change in the speaker's bass. You know how significant that is. So, one recommendation I could give you is to consider upgrading the speaker's internal wiring and caps. If you don't like the suggestion of changing external wiring, perhaps you will accept the experience of a person who does work in the studio and found that internal wiring and caps made a difference. 

As far as arguing with the people here with extensive experience who are trying to help you, go right ahead if you feel you must, but you are rejecting the very means you say you seek in fixing the problem. Please sit down in front of your rig with some different power, IC and speaker cables, and do some critical listening. I have had some well known industry members visit my room and hear comparisons between cables themselves. Like them, you will learn something. Now, if you are unwilling to do that, then cordially I am finished with our discussion.
