Cheap Tang Band mini Horns are back!

Take S3 down to 100 cm2 and you have a perfect rectangular 27L box. 30hz = 99.70 dB's & 11.29mm @ 21.34hz

Hi BP1Fanatic,

When I messed around with this driver I thought it was a little too touchy on the Wizard sliders when I reduced the volume to about 35 L, and it lost about 5 dB. Also, the impulse response looked bad. By the way, I found that adding about 5mH to the Le helped. But yes, it can be done.

It lost 5 dB's compared to which design specs?

Hi bjorno,

In Post #10: it looks like you're using 2 drivers in an isobaric configuration, and adjusted the T/S parameters respectively, you may want to double the Le as you're using the drivers in series.

I was trying to stay as small as possible and still reach 30hz.

Two 34L boxes puts me at 107 dB's @ 29.65 hz. Four boxes = 113.5 db's.

Hi.

Thank you TB46, Good to have someone here that is observant..

Luckily a correct double Le makes almost no difference to the shown FR.
