Thanks Amir. I keep being tempted to grab some of these for a 2 channel music amp off Parts Express, my preferred retailer for DIY stuff, just because these are probably the best modules they sell. It is good to know the performance is like this. I see why these are often used for subwoofers and woofers. From their AP data, the more powerful modules are almost proportionally noisier too, so if you get the big one, you really don't want it running your tweeters if you are picky. I guess if you need exactly this much power, if you insist on buying from PE, or if you need a small cool package and at this price point, there is an application for this in a music amp. I can pay a little more for some performance (Hypex or Purifi) or use my less powerful but otherwise superior A30. For a 2 channel setup, Loxjie A30, the $150 Yamaha receiver, or the one from Sony make more sense.
