horn speaker for car application

mhtplsh · 27th August 2007, 11:18 AM

Looking at the discussion going about hornspeakers, I am thinking about horn speaker for car application. Advantage will be low power amplifier. But the cabinet will be big.The solution will be making the compact cabinet of -3db response of 60hz. Now how to make the smallest cabinet with 8" woofer. Suggest some woofer.
what type of cabinet to be built for it?

horns are huge.. my folded horn in my truck is 9.8 cubic feet. I wouldn't go with it unless I didn't want trunk space

Thanks leadbelly,
I went to the site. It looks nice. But i will need to buy the speaker which they suggest. Then i can't do anything except the carpenter's work. I will be happy to go through the trouble of designing with the help from fellow members.

A little bigger and dual speakers but the design works great. I've built 3 different kinds. Dual 12 in, Dual 10in and Quad 10in. The last one is whats in my truck. I could post some pics if your interested.

i've done 46x36 (scale factor 1.2 for 2 12 in Rockfords) a 36x30 and a 36x36

the 36x30 is the double stacked 4 10's.

i want to first make 8" version. If successful, then i will try with bigger versions.
Can u suggest good 8" & 10" drivers?
I understand that low qts, low vas r important along with high BL.
any other T-S specs to consider?

Just model it as a 4th order bandpass, if a speaker works in that alignment, it would work as good speaker for this cabinet. Personally I looked for high x-max and high sensitivity. It is a pretty forgiving design.

people in the deacware forum r making wicked one subwoofer with different size of speakers including even 6" speakers.
They reduce/increase the size of the cabinet accordingly.
So one more thought came in my mind. I recently listened to T18 cabinet in a PA show.
If we make the downsize version of T18 similar to the people doing with decware wicked one,
what is the opinion of the knowledgeable people here about this.
