Satellites or full range?

It depends on so much, however, since very large speakers are designed to play loud then you have a better chance of success with a large box full range speaker. Generally you are looking at three way or a compression horn. Many or most small two way speakers will compress at even modest SPL levels, as they are designed more with domestic bliss in mind than playing loud dynamically (manufacturers will not put a high output tweeter in a small box - so often even the tweeter will compress).

Look for fat boxy speakers with a minimum of 8" woofers. Remember that efficiency is proportional to volume....the bigger the speaker volume then the more likely the bass will play loud without compression. Multiple drivers generally add to the load complexity - so it is probably better to get one very large high quality woofer type design in a large box volume than an array.

Possibility with the sub/sat is high. Often with full range, the best placement for midrange and up is not the best for bass and vice versa. In a comparison, the best chances for the sub/sat to win would be a lower x/o point and blending the phase where they hand off at that point.

Yes, I felt the sub got the low notes well, but it seemed to lack the mid bass warmth. When the bass can be handled by a couple 10 inch woofers and maybe a 12, the detail and ability to hear the full range is better. However, my friend's smaller room with the walls closer to the monitors helped the midbass warmth. I hope I explained that well.

Yes, clear now Hifimaniac. Thanks to all for the responses. Now I know the way to go.
