Can anyone help me if there is a recommended 12" tapped horn design works well from 45-125Hz soundwise and performance wise? Must be designed around two different brands available here in the USA I prefer Faital Pro 12" if it can be used as an alternate woofer (new ferrite line)? Thanks everyone!;)

This is a design I've been working on, the THAM12, perhaps it can be of intrest, drawings and numrous simulations can be found in the link below:

It's about half the size of the THAM15, I have not built these yet so I can not comment on real world performance.

TundraLTD, that design of yours sure looks nice, great response, and I really like the folding :)

12" Tapped Horn Plans?

I really want to use the Faital Pro brand I like the PS100, I've used B&C, 18Sound, RCF's, PD's (1850's) and really want to try faital his time around.

On another note Martinsson, I am just curious how did you fit the Turbo TSE111 phase plug to fit the B&C 10MD26??? You say it sounds good, the Fane has a different cone size and flatter on the cap??? Just curious, Thanks!

Is the MTH-30 pretty good with the Faital 12HP1010? Thanks everyone!;)

"They will be available in the US 1st quarter '12, Sensitivity for the 1030 is 95dB, 1010 is 96dB price MAP $348 1030 and $270 for 1010. I am leaning towards the 1030 2 X tapped cabinets. "

The sensitivity for any driver is in its mid-band, and has little to do with its efficiency in the bass.

Compare the Eta Zero (No%), and even then, some drivers work better than others in a TH.

The Celestion is a much better driver for the TH requirement you expressed, it is more efficient, and a fraction of the price.

Thanks , folding gives me a headache! It took me an entire day to make it work. I'm building a pair this weekend!
