Bass Attenuation - best approach

"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."

I don't know why you would assume the speakers are at fault. You heard the Theos in a different room with different electronics. To start with, I would bring your current electronics in to store that you heard the Theos and see how they sound with your gear.

Thanks for your responses. When I bought these I too was into HT and had all ML equipment with the Odysseys in the system as R and L fronts. When I switched back to 2 channel years ago I tried Electra and Nautilus for short periods but eventually returned to the Odysseys which, thank goodness, I had kept in storage. Having used ESL's for over 10 years before these, I guess I'm habituated to their sound.

I have not tried traps or any other type of room treatment primarily because my listening room, although fairly large, is our living room. I do have them located three and a half feet from the rear wall and about three feet from the side walls. I know from reading other comments that for best results they need even more room than that but most of us don't have that option.

I have completely enjoyed these for many years in the same environment as they now reside but hearing issues have progressed to the point that I don't do well even on a day to day basis when there are competing sounds. The quality of my equipment or listening environment, then, are important but my problem here is related more, I'm sure, to my own personal hearing issues.

Except for the expense involved I'm not adverse to the idea of trying the newer ML Theos or Ethos speakers but I'm still very satisfied with sound reproduction from the transducers; it's the woofer section (frequencies below about 350Hz) that I feel need taming.

I'll look into the PARC suggestion but continue pursuing the idea of adding resistance to the bass section and would appreciate any advice on that matter.

If you haven't tried it yet, you might experiment with room placement. A lot of the bass you hear is coming off the walls, so pulling the speakers out may reduce the overall bass a bit. As you get closer to/further from the walls, the frequency range that is being boosted by room reinforcement will change, as well. Simply shifting this frequency may also help with your issue. The results can be quite significant.

Also, it's free, so it's definitely worth a try, IMO.

You could try the dspeaker for around 1k . It is a small box and works wonders.
