JBL speakers and phase

[bigshot]

A friend of mine who builds speakers told me something very interesting today. He said that the phase on JBL speakers is the exact opposite of every other brand. What's red on a JBL is black on another brand of speaker. This could affect multi-channel sound systems where the rear or center speakers are a different brand than the mains. If one of the sets is JBL, and the other isn't, there's going to be phase cancellation.

"We've got some !JBL speakers hooked up to our stereo now, we used to have stock speakers, but we don't anymore! They sound great and comply with standards of + and _!"

Why use different brands, even brands' lines, in a multichannel setup? Timbre matching makes a big difference in surround setups.

Not everyone can afford the same speakers for the front as back. A lot of people use bookshelf speakers for their rear channel.

What's the difference (between bookshelf and surrounds)?

 

[bundee1]

Some speakers are designed to be surround speakers. They have different dispersion patterns or limited frequency ranges.

 

[Dusty Chalk]

But in what way would it be bad to use bookshelf speakers as surrounds?

 

[bundee1]

I cant think of a way unless your room layout calls for dipoles or bipoles so you dont get localized sounds from the rear.

We're not talking about using the same speakers, just speakers from the same manufacturer in the same line. Most manufacturers have rear speakers that are designed to be used with their other models, or at least a bookshelf model and a floorstanding model in the same line. For example, Totem Rainmakers closely match the Totem Forests tonally, so you could use them as surrounds, and use the Rainmaker center.

Whatever you do, all of the speakers should be designed to be similar tonally. It really is important.
