yup I hate Bose way to overpriced, I'm more looking into a stereo then surround sound, but i still want to be able to hook it up to my tv. Looked at the vega's and MTX has some that look similar. I could kick myself my bro just got rid of his vega speakers 3x5 monsters, probably about 20 years old but man they were loud.
Speakers (besides active speakers with built-in amplification) will only go as loud as any amplifier that is driving them.
However you can choose speakers with a higher sensitivity (measured by putting 1 watt of power into a speaker and taking the db reading from 1 metre in front of the speaker, or w/db/m for short) to gain more volume from an amp. The watts figure on the back of a speaker (usually something like 20W to 120W power handling) is usually just a range which the manufacturer recommends for that speaker, not actually what the speaker will produce.
This is why low powered valve amps (typically 25 wpc) tend to be used with very efficient speakers (90 w/db/m or above). If your amp is a bruiser, you can get away with much less efficient speakers.
The other variable is the manufacturers idea of what their amps are putting out. Many of the mainstream manufacturers use very flattering THD (total harmonic distortion) figures, which is why their massive stack systems say "500 Watts!!!" yet you can go home and max out the volume no problem (despite sounding distorted and rubbish).
You will blow a speaker easier and quicker by using a low powered amo and maxing it out than using a high powered amp. Low powered amos will reach a point where they start 'clipping' (throwing out spikes of distortion), this can often be heard when turning the volume control very, slowly usually as a
decrease in volume. Clipping will kill your speakers regardless of their power handling figures.
