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.

If they can't understand what was said on tv, then it's the midrange that needs to be more pronounced. Usually you can do this on a receiver by rolling off the bass and maybe accentuating the treble a bit. Adding a center channel may also help, but I think the key is turning down the bass.
While referring a friend to the Zvox family HT speakers, I noticed that they had added a "Dialog Emphasis" feature to their products. I'm sure that this is just a boost in the vocal range but, if you need it, it can be important.

Actually had some experience with this a couple of years ago while working at an A/V dealer.
Jmcgrogan2 is on the right track, however it seem to work best IME, to boost the treble more than the amount of roll off in the bass. I think this is due to the fact that, the more a treble control is increased, the band of affected frequencies generally widens, resulting in a boost much lower than the center point of the control. Also, we gradually lose our high frequency hearing as we get older.

This should help, however, if not enough, follow Marty’s advice with a center speaker.

If that’s still not enough, have their hearing tested.
Elizabeth,
Would this one work?
