I’m sharing my test results on a new horn design for a horn loaded 2-way bookshelf speaker using SB Acoustic drivers.

My second blog post on Speaker No.1159 is now published. I continue the comparison with the non-horn baffle and look closely at distortion sweeps as I increase the speaker's output to 100dB SPL. 1159 takes the lead remaining below 1% distortion while the non-horn version hits 5% distortion. I conclude that 1159 has 10dB more headroom even with a simple first order crossover at 1.5kHz.
