Merlin VSM

teeshot, in a 13 by 20 foot room with your amp you would have powerful and deep bass imho. i have used them at shows in up to 4400 cu ft volume with great results. i personally like the sound of the primare very much so no problems there. a vsm mxe or mme would be a better choice because they are lead free and do sound fuller and more room filling. i agree with what hifiman said in part but the sbam that comes with the vsm does a very similar thing by filtering out of band energy below the resonant frequency of the woofer. this reduces 2nd and 3rd order harmonic distortion in the bass. this can be decribed as the typical booming one hears in the bottom end of virtually all speakers unless they are protected in this manner.
what kind of cables are you planning on using? are the speaker wires single run or bi-wire?

af, what i think really happened was that i linked to a review that was just posted on my site. this may have crossed the line. sorry if i offended anyone. i think this would have helped teeshot get his question answered. you may think it grandstanding but it is just me relaying my opinions or the facts and usually much more of the latter.
best, b@merlin
