Two, the magic number. Chase the skirts for the poor running backs

It is common to put some type of damping material in a sub. Just think, it is a box with styrofoam tuned to a certain frequency based on the driver. Simple to make and can cost an arm and a leg, lol.

Buy an amp from China and have all the fidelity without the high price. Price does not equate to fidelity. A good used Mc Intosh will work if you like spending money.

Tube rolling is interesting but, it has it's limits on fidelity.

These amps are base on popular designs used in the U.S. and can be worked on if needed by qualifying technicians.

I have a similar amp from China and have no regrets or need to spend more, since these are excellent.

The above is not good advice. Yes, two subs will make the base response better in the room setup properly. The delay does not matter unless they are equal distance and the room is a perfect rectangle without non-symmetrical furnishings . I use multiple subs that are not the same with harmony. See graph attached to the post.

Ceiling speakers should work very well. I have in-surround back in-wall and and ceiling speakers. They work great and replaced other Klipsch speaker that were not in-wall. My only regret is not doing the change earlier and saving some money.

Get a pair of RF 7II or RF 7III and be done with it. You need not get another pair of speakers for the rest of your life.

The amps from China are great but, if you are happy with the system, you are DONE!

It is good to hear you are doing better. You have things under control with the deoxit!

Time for a top ten shuffle.

Leave auto features active It uses minimal energy and protects the amp somewhat. 🌝

It should go a bit lower: keep both IMO.

The RC 64III will offer a bigger sound stage compared to the 4500 center. I use an ext. amp for the front speakers and atmos speakers and use the avr for rest of the speakers. I have been know to run the system to 0 or the max. 😞
