MaVo - I planning on building a pair of your 38 Hz Tang Band tapped horns.

Thats not me, its Volvotreter you seek.

It makes the horn big. No other reason. When a Tapped Horn becomes very large, it no longer has an advantage over a FLH.

Bigger is still better, in an absolute sense. The smaller one is only better in a relative sense (relative to a similar sized flh). Its cool in a technical way to have a "size efficient" design, which makes alot of sound out of a small enclosure, but making it bigger makes it sound better.

The reason one doesnt see so big ths is simply that they are so big. Virtually no one wants a cubic meter of subwoofer.

BIB rules for sure, but yeah, even I 'draw the line' at ~30 ft^3 (~0.85 m^3) cabs for various reasons.

OK, that makes more sense

Sorry, no, you'll just have to do a search of 'GM' and isolate the posts on this thread AFAIK. With 547 TH designs currently in Hornresp it's not simple to find them scanning it either.

No worries GM, I'll do some searching and do some comparisons before I post up my design for criticism/suggestions.

Hi Chris,

Here is my first fold for the Lab12 driver. It's an honest 18 ft and should go below 20 Hz.

MaVo did a great job on the original sim, but I had to make some changes to get it to fit into a box.

Thank you so much! What do you mean by "first fold"

[Don Snyder]

...and here's the sim. I'm thinking of other ways I might fold it, perhaps like volvotreeter folded his Eminence horn.

This will be the easiest one to build, I'm sure.

Has anyone built or run the numbers for the Dayton DVC 12"?

Not till now AFAIK. Using published specs it looks good enough in a ~14 Hz, ~362 L conic TH, though it really wants to be in a larger, longer, lower tuned TH.

Well, I've tried repeatedly to post the Hornresp specs, but I keep getting an upload error message.

Don Snyder, would you have a frequency response graph for this fold? Which Eminence driver is this as per their catalogue?

Thanks,

Bump!!

Thanks again,

For Samuel Jayaraj

Back on post #2086, I attached an alternate folding for Cowan's / MikeHunt79's 30Hz Tapped Horn. The driver is the Eminence Definimax 4012HO.

Here is the HornResp data.
