Thanks zirk . I have been looking at sound bars/bases for our other tv too.
Do what you recommend improve dialogue too? I also find some dialogue is drowned out by background music, sound effects.
Take you mean speech (mainly Movies related) where the speech goes quiet or is drowned out by, as you say music or sound effects, turn the volume up and next minute its all too loud, the main reason is this is due to the original surround sound track (say 5.1) not getting mixed down properly for 2.1 listening, bloodly annoying late at night, this is why a 5.1 surround system has a center / middle speaker, the diologe or main speech comes from the center and the souround sound is distinctively spaced away near the walls.
Not much you can do about that with some remixing of the channels with additional equipment or go down the full 5.1 / 9.1 sound system.
The Maxell does have an SRS, which effectively pulls the the 2 steroe source's away from the middle, which can help for speech, but I not going to say its a 100% cure for it.
If you do want a 5.1 system but dont want the hassle of speakers and wires around the room, have a look at the Yamaha Sound bars, in particular the older versions, there a Sound bar you hang on the wall (Higher the better), they are noise calibrated with a reference microphone, and them bounce the channels around the room all from a single Bar, sounds wierd but they really do work well.
Ive used one of these before, Yamaha YSP800 and Loewe (made by Harman Kardon) do a couple of good ones, but they are bloody expensive new, but can be picked up secondhand for a bargain if you wait or hunt around, you will probably need an additional decent Sub Box for these as well to balance the sound.
