I have a pair of Alto TX8's and they sound very nice, but they're not very efficient. When I bought them they had a big 280 watt sticker on them. After doing some math with the db and efficiency ratings, they came out to sub 100 watts RMS.
The Trouper is 65 watts RMS to the 3 woofers at about 22 watts each and 35 watts to the HF driver. This is normally rated at a single frequency. At their continious power rating they are rated at 117db at one meter. That's pretty good. I think you would need two to cover most rooms. The drivers are not offset at angles. This is similar to the less expensive Kustom/PowerWerks PA50/PW50. Just off the published specs I do not believe they're competitors for the SA220 or L1 Compact. That being said, I'll bet a pair of them stereo linked will make a nice compact system. Two Kustom PA50's linked make a system that can cover a noisy crowd of 50. Ric
