Hmm, to my way of thinking, no way to answer this correctly without knowing the desired gain BW.........

Hi, bit of a test hey

I'm presuming that,

fd = fs

Qmd = Qms

Qed = Qms

Vad = Vas

Qtd = Qts

I'm used to seeing the TSP's written as in the second column !

Well taking into account they all have the same Sd & Fs & Re, based on several factors including, high BL & a stiffer cone & high SPL, it "appears" that A1a "might" be better. What's the word ?

@ GM

Indeed, but i think i understand why he posted the test

Well, A1b for the alignments that interest me.

So theres a bunch of terms in designing a tapped horn that are totally alien to me, having worked a bit with loudspeaker design cookbook.

can someone post a list of these and the relevant TS parameters.

when designing ported/sealed boxes i would chose a cutoff and driver and hunt for a design that hit most closely, taking into account location and bass lift from it.

It was noted above that there are car audio woofers that would do well in a TH.

Car designed woofers are often SEVERELY abused thermally and driven at box tuning with thousands of watts.

It seems that the stress on the driver in a TH is over multiple frequencies.
