Borresen X3

The X3 is a phenomenal speaker way better than the Focal Kanta 2, well worth the $11,000 asking price, there's one speaker I like better though and that's the monitor audio platinum 200 and 300 G2 and G3.

The Cabinet on the X3's is worth 11K. The beautiful music that they produce is just icing on the cake!

I think mtbiker29 makes an important observation at 50.8 x 13.6 x 23.9"   the X3 is a somewhat large and deep cabinet. I don't think I have the room necessary for a rear-ported cabinet that deep which is too bad as I think the X3 has a lot to offer for the price of $11,000. In reasonable comparison, for example, the Perlisten S5t is priced at $13,900 but does have the Beryllium tweeter. The cabinet size is more room-friendly at 44.1 x 9.5 x 15.8”. and can be configured as sealed or ported which is desirable in my opinion.  
I am impressed by both designs. Better yet, the possibility of a good amount of value preowned in the 8-10k range between the two.
