Horn

1. Find a pre existing design
2. Study for ages,ask questions and eventually design something with some one helping you making sure you dont make scrap plywood.

Id REALLY reccomend 1. There are clones of the WSX or SL36,either would do.I can post links to those.

Now il ask some questions
-Boundarys? wall loaded?
-Box number?
-SPL or extension preferred?

Thanks for the reply. SPL is prefered over extension becuase this is for a mobile DJ.

One box would probably be better than two, but I could talk to him and see how he'd feel about two.

Thanks for the plans, do you/anyone have a suggestion for around 300-400 in parts (excluding wood, screws, etc, and even x-over possibly).
 
Three main choices
1850
WSX
T36

All requiring an 18" driver. With only 2 enclosures,a bandpass box maybe easier to build while less bulky,quality would be worse.

Youl require active filtering + amplification in the order of 400w-1200w RMS

Ive listened to two WSX horns in a small club and am entirely happy with them,but I havent heard any other basshorns.

More options.

Lastly,if your REALLY short on cash two tempest horns could be a way to go,cheap driver and decent kick. I cant say how well they work in reality however,they seem to be based on the CV design.

Here's a Cerwin Vega design, vh35, pre sl36. pre el36

"The Tuba 36 looks promising though..."

Here is what one of the BF Tuba's actually does:

The cyclical peaks and dips are from too small of a mouth. If you used eight of so in a stack it would smooth out quite a bit.

Here is what four Eminence can do in a tapped horn design:

Each box ends up about 36x36x24W
