Parents need clear sounding 2 ch HT


My parents are always complaing they can't understand what was said on their TV. I set them up with a Pioneer digital receiver and set of Solioquy bookshelves.
This was before HDMI and i ran the 2ch out from tv into receiver.
My question is how do i get them better, more clear sound? Do i need to scrap anything or just get an integrated that accepts hdmi? New speakers? I'm not sure what course i should take.

Do they want/need HD and HDMI? If so, you need to buy them an AVR. I know of no 2 channel receivers that support HDMI. They can keep the same two speakers although adding a center channel might be of assistance in voice clarity.

I think your parents are suffering hearing issues that seem to them as garbled sounds but is really a medical matter. They probably need the speakers near to them and the volume on the louder side for them to be satisfied. I would advise them to get their hearing tested. Then other options aside from what I suggested may be appropriate.

Room treatments will reduce reverberation and improve clarity. When I bought acoustic panels warehouse clerk showed me conference room that they treated 100% with acoustic fiberglass foam (floor to ceiling between studs). Sound was amazing. I've never heard another person speaking with such clarity, sound coming directly from his mouth. It was amazing. Perhaps it is not good for music, being over-damped, but is perfect for clarity.
