DIY multicell horn

[jipihorn]

Hello,

I've found by chance this post, and I'm very happy to see that my site has been seen from other countries... And thankyou for your interest into our (my brother and I) horns. They are not copies of Ledauphin horn and the construction is different (and lesss risky) even if the result is the same (and much pleasant to look !). I have to scan the pictures of the construction and put them on line.

As it takes a long time to translate the whole site in english, it's still in French...

If you have any questions about the content of the site, you can write to me !

>Hi GM,

How to add a "sub" in the lower section?

====

Not much to tell. Block off the driver area to create a compression chamber, romove the two vent baffle boards and replace them with a sub driver/vent(s) baffle board to suit. I recommend adding some bracing.

If there's archives, I mentioned this awhile back and Roland (haven't seen him post in some time now) liked the idea, added a JBL 2245? and seemed quite pleased with it, though I'm sure other drivers will work also. I used a 411-8A in mine way back when they first came out. Really, with these new low Vas/low Fs sub drivers, using two in a bipole layout would be best, but then you would have to cut up the cab, which for some would consider it heresy. Due to efficiency differences, bi-amping is best.

Hi, GM

I have seen a people turned his 828cabs up side down. Bass horn on the bottom. Then used 2 pieces of plywood to cover the bass horn. Just leave a 1 inch gap as vent. The 515B mounted on the baffle. This way can makes the cab provide more rich bass. Although LF and HF not on the same point. but Sound stage still very great.

have you or anybody has tried?

No, it never occurred to me.

I know some peoples would like to add a sub woofer(s) to their VOTT system.
But I interested to your mentioned that relating to add a sub woofer(s) in 828 cabs. Which one of sub you would suggest? Cause that lights up my greed to quest for the higher music reproduce.

Best regard

Roland's choice of the JBL 2245H appears to be a good one. Altec's 3156 looks good also, if you can find some.
