Borresen X3

Thank you, hilde45 

I am also courious how the X3 might compare to the Raidho C 2.1

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.
