One of my piles of loudspeakers in the living room ;-)

On top the very rare, the Philips VN3100-25 (OEM version of the Stage Accompany Blue Box).

Then the real SA Blue Box (SA4525), still an awesome sounding enclosure!

Both the Philips VN3100-25 and SA Blue Box have a build in amp, the PMS-5000.
They use both the SA8525 Ribbon Compact Driver and the SA1513 woofer.

To complement the above, the SA P17 sub (with double SA1513 woofer), the best sounding sub SA ever made.
