Center channel for monitor 70 series ii

Well, I've heard a couple of systems where the center channel isn't matched, and in most cases, it wasn't displeasing at all. This happens especially with those who have older speakers or stereo speakers that do not have a corresponding center (i.e. lines intended at music enthusiast, more than HT).

My guess is that you need to go for something that is at the very least similar in design (especially the tweeter, for example), but you might give other Polk series a go : I haven't heard the T series, but they seem to be the successor to the Monitor/TSi. They might not sound identical, and they surely do not look the same, but unless you can find a used Monitor at a decent price, they would be my best bet. If you don't like it, just send it back.

After that would be the RTiA line, but it probably wouldn't sound entirely the same.

Anyway, if you have Audyssey or any other auto calibration software, the tonal difference between your L/R speakers and your center might end up being minimal, as long as they share "similar" enough components.
