Inserting horn(s) into 2x15

[PuffusMaximus]

any thoughts on putting a horn in this cabinet? i would like the cab to be able to put out some more high end

[bassteban]

I may be the least-qualified TBer to comment here, but I'd guess that adding anything that will take up internal space will change the cab's tuning- perhaps quire adversely. You may get better results replacing the cab w/something more full-range, or incorporating a crossover & higher-end-specific cab. Again, a semi-educated guess.

or just build a top box
if you want to keep that bass cab

Another guess- *top box*=smaller, more upper-range cabinet- 4x8", 4x5", something like that. I'm thinking you don't want to pump straight bass into one, as it may not work well for the lows. A crossover will divide the lows(for the 2x15)& highs(for the *top*), for better efficiency. Again, I am no expert and am responding mostly to give you a bump & hopefully attract the attention of someone who knows these things. That and I can't sleep.

i was thinking the same thing

A little separate, one or two 6" +/- tweet in a little box to put on top. Bi-amp or include built-in passive crossover with a "low out" to connect bottom cab. fEARful headcase comes to mind.

[babebambi]

Build an additional small box to house the horn (ideally it would be hi, and mid range drivers), instead of putting the horn in the existing cab. If you want to do it properly, you gonna need to have a crossover too.

OTOH, if you just want to throw something together for fun, I suggest that you get an A/B/Y box for the bass signal, then just run a small guitar combo in addition to that bass cab and your bass amp.

so would i connect the head to the headcase, and then the head case to the main cab?

Right....The crossover would be housed in the top box.
(HINT) use a 6.5" mid cone such as 18Sound 6md410. (check out the fEarful headcase.)

Heres a little "thinking outside of the box".....
Instead of trying to add a horn via topbox, why not change one of the existing 15" for a coaxial 15".
Bad idea?

US Speaker.com has several coaxial 12's and 15's

You could do this but the 15's would have to be in completely separate chambers with no air leaks. They would also need to be individually tuned to their specific needs. It can be done, you just need to know this. Since the least expensive coax in your list is $460 I'm going to guess it is a no-go :0

Yikes! I didn't notice the price before........topbox sounds good.

In your original post,I think you wanted to use a horn tweeter.? I don't think you even need a box to try it out, just set it on top. If it sounds good, (you'd need a crossover) you could use the appropriate-sized hole saw and mount it on the baffle, below that upper port(it looks like there is room).

If your lucky, and the tweeters hole is the same as the port tubes, I'd try to remove the upper port, put the tweeter there, then put the port below that. (maintaining 1/2 port-diameter spacing all around).

A horn tweeter should be sealed, and I don't thing it will have enough volume to affect the tuning of that large cab.

[MuzikMan]

Ideally the OP should look for a horn capable of 800hz or lower to properly match the dispersion characteristics of a 15" driver. You just won't find that in a little 3" round horn. This can be a fairly expensive project to do properly. It would be cost effective to move to a three way design with a dedicated mid and small tweeter...................or you could just throw a horn that will fit in there somewhere!!!

what is the baffle?

[gregoire1]

The baffle is the front of your cab. The board your speakers are attached to.
