I asked a question In av forums about the tsi100 speaker. the answer was the tsi100 was a replacement for the monitor30. my question on this If so, what are the difference's between them??

I just did some more looking, on your behalf.

The TSI line is NOT a replacement for the Monitor line. It sounds like the TSI line will be, perhaps, a Best Buy exclusive. When I look at the specs I think the TSI line is pretty much the same as the Monitor line with a few small tweaks. The cabinet is a little different, the crossover has been tweaked (at least comparing the TSI 300 to the Monitor 50), the TSI digs a little deeper (perhaps5-10 dB lower).

So consider it the monitor speaker tweaked all around. I wouldn't plan on more than a 5% improvement over the equivalent monitor speaker though.

Feel free to browse the Polkaudio.com forums and you might find more info.

This is just one man's wild ass guess too. I haven't seen anyone who's done a side by side comparison of the two speakers yet.

once again jnickrand thnx another choice has been mentioned. Infinity beta 20's. would they be as good or better??

Here is my problem with lower end / budget 'exclusive' items – Nine times out if ten they take a decent product and modify it to be easier to sell. And easier to sell doesn't necessarily mean better. In this case the TSI playing a bit lower probably won't mean much if you are using a sub. It probably just means it will sound better in the store, where it probably won't be hooked to a sub.

Personally I would go with a tried and true Monitor 50 over something new like this, until at least this TSI gets some reviews and feedback.
