Snell A7 Illusion

I also wonder if there are many rooms that can support 20 Hz, it most rooms I would think that capability in a speaker would be lost with typical room acoustics. If this speaker is flat at 30Hz I can't imagine feeling like you are missing very much of the lowest bass on almost all recordings.

You'll be surprised ... My Infinity Prelude MTS has this RABOS adjustment CD with tone tracks centered at many frequencies for the bass. At both houses, the 20-Hz level definitely created serious rumbles without shaking something in the room and generate higher-frequency noise.

Stereophile indicates that the Illusion would do fine at the upper 20's Hz, and I believe so. Frankly I didn't notice any lacking when playing regular pop rock music at the stereo store.

The Snell A7 illusion has a sibling called the Phantom B7.

I just heard a pair of Snell Phantom B7 speakers. Look and sound just like the Snell A7 illusion except smaller and half the price @ 25K.

A couple years ago I listened to the Snell A7 speakers and was very impressed with those. But at $50K I would rather spend $25K and purchase the Snell Phantom B7 speakers.

Both Snell speakers souund similar but smaller version. The Phantom B7 speakers don' overpower the room. You need an extremely large listening room for the A7 speakers.

The better value is the Snell Phantom B7 if you love both speakers and only want to spend $25K verse $50K.

Both great sounding speakers in my opinion.
