with just 2 of the 4 ports? did you do anything scientific to work it out, or just went for it? how do you think they sound?

one single have 2 port. Same tune of one double. Calculated using my akabak sim. My version have quarter circular port. Why? because i like it more.
I use them from 200 to 1khz, I tested still 1,5khz but start to distort a bit. They sound good, no too much spl but pretty smooth, to me is in the middle between a full horn and a sealed chamber. They drops around 120hz but they haven't an aggressive kick.

cool, nice one. good info. i'd be hoping to use mine from about 150hz up to 1.2khz or so. what size circular ports did you settle on?

i spoke with stipe earlier this year about making single 12" with comps and he advised me that the ports would be excatly half of the original drawing.

Umnfortunately, I haven't had time to build them yet but I will get round to it eventually.

They are heavy enough with 2 PDN12.SB30's and 2 Fane CD280's made of 15mm Birch Ply. if your thinking of using 18mm the will probably be a two man lift.

Good luck with your build. smiley20

Hey people! I'm new on this site, just wondered if the single 12 inch version could be used with a 1.4" p.audio compression driver on one of the 18 sound plastic 1.4 horns, many thanks cheers
