High Efficiency Dynamic Speaker Suggestions Please

Hi Phil, thanks for the additional room information.

To answer your question, I tried to design my speakers in anticipation of a wide variety of amps - but specifically, they work best with low damping factor tube amps (assuming the port tuning is adjusted accordingly). I used Atma-Sphere's 30-watt stereo OTL amplifier in the design stage. My speakers also work well with SET amps; the smallest amp I've heard of a customer getting good results with was a 3.5 watt SET. They'd work with push-pull tube amps as well, especially those with low global feedback (which implies a low damping factor). Actually they'll work with other amps (I use a Nuforce sometimes), but with high-damping-factor amps they like a bit of boundary reinforcement in most rooms, or else they like to be tuned a bit higher than normal to give more energy around 40 Hz. The only amp I've heard them not work well with was a First Watt by Nelson Pass, presumably because the extremely low damping factor of those amps was too low for my design (which frankly surprised and disappointed me a bit - I was hoping that would be a nice combination, as I like Nelson Pass's designs).

Jaybo, any amp suggestions? The hypex class d sound very good to me and I thought my speakers were voiced with them. Phil Brady

phil...i had a friend who was a VS nut, and had a shop in minnesota for a few years. his amps of choice for VS speakers were electrocompaniet, and naim. i am more old school with amps, but i've been awfully impressed with the new bel canto class D's....i also have found that reasonably powerful mosfet designs make the bigger box speakers sound more transparent, and don't necc sacrifice anything on the bottom. the VS should rise to the occasion

horns are ACTUALLY just that...they allow you to imagine you are at a live performance! i personally consider that accuracy not coloration...but yes, as with all loudspeakers, its interpretation. :)
