Crazy box design - Input please!

old skool junkie · 18th May 2011, 07:26 AM

Hello all. I've been browsing around the forum for a while now, and I must say: I feel belittled

Before coming here, I would like to have thought I was "savvy" in regards to woofers/enclosures.. Clearly not the case.

So, in my humblest of requests - can someone tell me what kind of "Franken-box" I've designed here?? And how would I go about modeling this on AkAbak/HornResp? Thanks in advance to all who can help

I literally "winged it", with only basic principles in tact. It falls on its face under 45hz, but 50-90hz is incredible. With the high cutoff however, it makes for a TERRIBLE substage in the Jeep

What is your theory here? Sort of a backloaded, tapped horn, ported box?

This might work

OR, this.... but your original has too many things wrong.

Well, from what I "think" I understand (lol).. It's a series tuned 4th order (again, I think) combined with a tapped flared "horn" style mouth. I honestly don't know what I was thinking haha. Turned out to be pretty darn loud 45hz+. Sounds great on rock, jazz, etc. Just not "well rounded" for all music, which is my goal.

the upper pic acts like daccv box. hornresp say "no" akakbak might be but i don't know the best point of the design. the lower pic can do it easy. the front acts like short horn and behind is br chamber. the lower pic might be clever box

Hmm. Some sort of TL or TH with a Helmholtz resonator?
