silly HT front/rear matching question?

Hi all. I'm new to this forum but so many of you sound so knowledgable I'm hoping you won't mind helping me with a dumb question.

I'm upgrading from a 2 speaker to a 5.1 speaker system. And be warned-i'm not an audiophile. My question is, why should I go to the bother and expense matching the rear surround speakers with the front/center speakers? When playing music with e.g., Neo6 the rears seem to be just for a little fill. And for movies, is it that important that they timbre match?

Oh, in case it matters in your answer, because my sofa is against the rear wall and the surrounds need to go near the sofa, I guess need to go with dipole surrounds.

I'm leaning toward the Paradigm studio line for the front and saving $500 by getting a more modest surround, also Paradigm, but of a different line that won't match the studios.

Thanks in advance,
I think you will be just fine with less expensive surround speakers. If you're mounting the surrounds on the side walls, it's almost impossible to timbre match these speakers to the fronts anyway. In my last theater, I had the full Revel Ultima line of speakers, and even for this highly regarded $20K+ speaker system, the surrounds still sounded very different than the fronts. Did this detract from the movie experience? I never noticed it.

For movies, the vast majority of surround effects are mixed in independently of the front channel information anyway. Occasionally, you'll have sounds that move between the surrounds and front speakers, but this is not the norm. With multi-channel music, you may notice it a little more, but I don't think it will make that much difference.

In my new theater, I am using Revel C50/F50s in the front, but relatively inexpensive B&W speakers for the surrounds (sides and rears).

If the timbre mismatch really bugs you, you can always add a parametric equalizer for your surround channels (assuming you're using a separate amp). Rane makes some pretty decent ones and you'd probably get a better timbre match this way than using the so-called matched surround speakers.

If you really want to have optimal timbre matching, the only way to do it is to use the same speakers for all speaker positions and make sure that they are placed in approximately the same position relative to room boundaries.
Thanks JTor. I'm taking your advice and am not going to worry about timbre matching fronts and rears.

Bomarc - I really think you hit the nail on the head. Sometimes you have to listen to your little voice and ignore the "experts".
Home theater is a waste of cash buy quality 2 channel your money goes alot farther if you really value music .Take care
