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.
Clearer sound is possible.
Various speakers have clarity as a feature.
I find one of the best are Canton speakers with the 4" aluminum cones. The Canton CD series.
Then a small power conditioner can help clean up the sound.
For an inexpensive means some computer speakers can do.
The speakers in the TV are really nearly always poor quality.
