Hello,

If the simulations are right, the X-tro will be flat to 90Hz. Two prototypes will be constructed within a few weeks so then we will know for sure. Halfspace efficiency will be around 105-106dB/1w/1m.

The X-tro uses 2x15" on a horn with a throat of 1200cm2. This very large throat helps to reach 90Hz. A 12" horn with a 300cm2 throat would have to be considerably larger to reach 90hz.

Best regards,

Walt
