Mentioned this a few times but only recently got round to doing any serious testing. Not claiming anything special just a tiny 12" Tapped Horn. Size is 550w x 370h x 455d

Much better performance than with the driver in a ported cab. Output is about 2.5db down on my THAM15's and it looses about 8hz on the bottom end.

Driver is the Celestion FTR12-4080HDX

Design is inspired by Martinsson's THAM15's which still put an enormous stupid grin on my face.

The double 12's have the extension of the THAM15 and sound good up to 200hz, The tapped has  more output and sounds excellent when used 45-150hz, it is silly powerful for its size :)

Just wondering why you haven't used one of your BMS 12" drivers for the tapped horn, are they not suited to that type of design.
help!!!!!!!!!!

As you say not suited, for this type of design a highish Fs is a big plus.

looks good. smaller than the mth30 and seems to go a little lower with same efficiency (is it 1w measurement?). will you post the plans?

Yes indeed, as soon as I have tidied up my drawing I will do a PDF.

Regarding other drivers, as long as they are pretty close to the T/S parameters they should work.

No the measurements are not to a reference level. You have to ignore the simulated output level as well, the only way is to build and measure which is the only way I will ever do it.

From memory the path is longer than the MTH but I suspect that it will probably not be as efficient as it is a smaller box, there is no such thing as a free lunch.
