Hi epa, it looks quite good, I have done some Google SketchUp8 plans.

P is for Parabolic, you have constant width and should probably sim it as parabolic instead of conic.

Thanks NEO Dan, yes I know it is much easier to construct box with 90 degree inside pannels. Inside the box I have 5 five volumes, Volume1<Volume2<Volume3<Volume4<Volume5, so how I can change sim from conic to parabolic?

 

[NEO Dan]

Tap the P key in the length (L12-L45) fields where you have conic now.

Thanks NEO Dan, have just done that, but it is small small deviations between Par, Con and Exp. The most closer to the real volume is under Exp.

I would re-name that cabinet, as to not confuse it with the Danley Sound Labs TH-118...

Hi,

yes thanks for proposal, I will do that it should to be called: 19 Hz Tapped Horn as 1/4 horn path is 15 foot long

 

[ZivkoF]

OK I have the final name: TH1819 (Tapped Horn 1819), first two numbers are for the driver (18-inch) and second two numbers (or one) are for the frequency (1/4 sound wave for horn path is 15 foot long which is 19 Hz), so you know the tune frequency.

TH_1819 SPL Response @ 2,0 Pi and 0,5 Pi.
