[QUOTE="Peter van Gils, post: 206318, member: 3943"] The BMS 2230 horn is too short / cut off frequency too high. You want to have the cut off frequency almost factor 2 lower than the x-over frequency. The RCF HF950 has a cut off of 400 Hz and is already falling off several dB at 700 Hz. The 12" horn can't go higher, so for this design you need a long HF horn... I only know 1.4" horns that are commercially available *and* fit (in) the DIY... Sent from my iPhone [/QUOTE]
