Bass Attenuation - best approach


I've been using the Martin Logan Odyssey speakers since new about 14 yrs ago and have been very happy with them in almost all respects. 2 days ago, however, I auditioned a pair of Martin Logan Theos speakers and heard what I thought to be, better detail in the upper mid ranges. I know that improvements in ML's overall technology has been made but I'm wondering if some of this "improvement" , at least to my ear, has something to do with the more limited bass output of the Theos. It's not that the Odysseys are lacking in the upper registers, but I feel that the bass output interferes or detracts from my appreciation of them. It's not that it's muddy or boomy; it's just there. I do have personal hearing issues (I'm 72 yrs old) that may contribute to this phenomenon but I'm looking for the best way to make an adjustment to accommodate my listening tastes.

My understanding of the most obvious fixes include using a good equalizer or going back to bi-wiring and installing resistance in the bass path. What I'm hoping for, then, is some advice regarding the best approach to this issue and will appreciate any that's offered.

My equipment is: Shanling CD100 disk player, Peachtree Audio Nova used as a preamp and Peachtree audio 220W power amp.

For some reason Audiogon doesn't allow me to submit a post except on an occasional basis and then, only if I tinker around with signing in for awhile and if I start a new thread instead of continuing with my existing one. The original thread solicited advice regarding attenuation of bass for my Martin Logan Odysseys that I've owned since new many years ago.

I received several pertinent comments but decided that if I considered all the possible causes of this real or perceived issue of exaggerated bass I could spend a lot of time and money chasing a solution so decided to change speakers instead. In Over 50 years of using many different and several types of speaker, although I don't claim them to be the best speaker type for everyone, I've become habituated to electrostats having used them primarily for 30+ years. I decided, then, to look at newer models and, because of their exceptional customer service, chose to stay with Martin Logan.

I auditioned the Theos primarily because of its price, and was thoroughly impressed with reproduction in the upper mid frequencies, which is where much of my age related hearing issues occur. I was going to order them but decided on the Ethos instead; it uses a powered instead of a passive woofer section giving it the capability of somewhat lower frequencies for those occasional movie watching times when I would like deeper bass. I also bought their small Dynamo 500 sub. Because I'll be using the LFE connection I will not have control of crossover points on the subwoofer which may be another issue altogether. I'll report on the results of this new setup in a few weeks; I won't take delivery of the new speakers until December first.

BTW, my current system is Shanling CD100 CD player or Apple TV using ALAC files as source, Peachtree Audio Nova as preamp, Peachtree Audio 220 power amp and Martin Logan Odyssey speakers.
Measure the woofer resistance with an ohm meter to see if it is 4 ohm or 8 ohm. It likely is one of the 2. Then purchase an L-Pad from Parts Express in the right resistance. This will keep your crossover working at the right point, just hook the l-pad right before the woofer. Use wire that lets it sit outside the speaker, right behind it, for convenience. Dial away to the point you like!
I would second the Lpad idea, there is a Radio shack in wall volume control with transformers.
Thanks. I did buy the Lpad but decided on another approach. I traded the Martin Logan Odysseys that I've had since new, for the newer ML Theos. It has a very useable bass control rheostat and performs as well as the Odysseys in most ways and, possibly, is superior in the upper midrange frequencies. I think my problem in mostly solved.
