M&K THX speakers for home theater

I am planning to buy M&K (THX) speakers for home theater. Which option is preferable: active or passive? Any other recommendations for better speakers? (Khalid)
Active. You will never look back. Done right this always has much better driver integration and much lower IM distortion than an equivalent passive design.
I agree with Shadorne, go active. I have the M&K S-150 THX passive and they are the best speakers I have heard to date. They replaced a pair of Spendor S8e for $1000 less. If I didn't already have an investment in a pair of Bryston 7B-SST monoblocks I would have bought the active versions. When you consider total system costs, active will save you quite a bit of money.

Which active speakers do you plan on buying, the S-150 THX (consumer), MPS-2510P (pro) or the MPS-1611P (pro)? I've been told that the S-150 and the MPS-2510 are identical.

I also suggest you use an M&K subwoofer. I've been very happy with the MPS-5310.
