I am completely new to a lot of things… horn resp is one of those. I was hoping some compassionate and caring soul would do something for me. TH-Spud clones with planet audio AC8D speakers. If someone would be so kind as to model this scenario for me I would be forever in debt! Any takers?
Thank you sonomanie! I had already researched that and plan something similar, but I wish to know if my driver choice will work. I chose the AC8D because it has 10mm one way Xmas so that’s 20mm total to tap out.
Fqu8847,
The AC8D 10mm Xmax is only 20% less than the Tang Band W8-740P linked in post #2, but it's Fs is 39 Hz, compared to 30Hz (1/3 octave lower), and QTS is .633 compared to .288, over double.
The much higher QTS and Fs will result in far less low frequency output, and deeper LF response dips.
For a "Spud like" 19Hz TH, you should be looking for a driver with a lower FS, and much lower QTS.

Thanks to you as well weltersys!!! What are the opinions on this one?

The Visaton GF 200 8" TS specs are about halfway between the AC8D specs and the Tang Band W8-740P.
Costs more, won't work as well as the W8-740P in the type of cabinet you are considering.
As a "compassionate and caring soul", I'd suggest using the driver that has proven to test well

Weltersys I proudly commend you’re input! I am new to TH’s and there are several ideas, however,I really like the Spud my problem is the recommended driver is $120+still doable since money wouldn’t be an considering 4 of them but parts express the only place I can find them has a 50 minimum… not going to spend that much when I only would need 4.
I just checked this driver in HR and it's pretty severely under-damped, though it won't be that bad in reality, peaking at ~111 dB/m/17 Hz/12 W/1 pi.
edit: inputted some measured TB W8-470P specs and it's actually a bit more under-damped, though weltersys' quite different specs are a near perfect overlay to it, so the 55-2421 at least sims a winner.
