Regulars to Sunny Components know that we have not one, but two demo pairs of this incredible loudspeaker, one of the best on earth. We have a pair in Black, and the other in Desert Silver.

The Alexandria XLF features a 1-inch super-tweeter, a 1-inch tweeter, two 7-inch midranges, a 13-inch woofer, and a 15-inch woofer. They have a 93.5 dB sensitivity, and go down to 19.5 Hz.
