Do you mean getting 2 different frequency speakers, HF & LF?

Can you recommend some for me to study further?

I opened the tower to have a look. The repair tech did a good job. He replaced the membranes, not what I said earlier about gluing the torn parts together. Can't remember which membrane type he used, soft, hard, etc. Think the original Onkyo membranes were paper-type, thus torn easily.

Thanks.

Thanks.

Hope that you can help me. Plan to put my Yamaha sub woofer off the floor, instead of on the floor. I want to get better, clear, and more powerful bass.

I thought the on-the-floor layout would give better bass with the floor vibrating. But now think that instead of wasting that energy to vibrate the floor, it better uses that for the bass sound production. Ha.
