I'm new to this forum so thanx for checking out this post.
I've got a pair of peavey scorpion 10's and a set of tweeters out of a set of jbl pro home speakers. If anyone has any thoughts on the best design for a cabinet or what frequencies i should use for crossovers for this setup i would really appreciate it. THanx.

Please post the model number of the JBL tweeters and the T/S specs of the Scorpion 10's. I'll betcha you'll get some good responses. You can probably build a pretty good little two-way system with those, provided the two drivers reach one another in frequency response.

here is a link also for someone selling these tweets on e-bay so you can see them for yourself.

These will work well in a 0.5ft3 to 5.0ft3 cabinet port tuned to 45Hz. They're probably even better suited for a sealed box larger than 1.0ft3. As for the tweeter, you'll probably want to horn load it, and you'll want to obtain frequency response graphs of both the midwoofer and tweeter to decide on a crossover point and overall suitability.

first off thanx for the help. secondly, i'm new at this so could you please explain what you mean by "horn load it". I also have an older set of foster soft dome tweeters. would they be a better choice. I don't have a model # for them as they are in the temporary cabinet i am using along with the peavey drivers and i am reluctant to remove them. Thanx again.

To horn load the tweeter means you will mount it on a horn. If it isn't designed for that purpose, it probably won't be sensitive enough to match your midwoofer at 99dB/W/M.

Hi SFR,
For the woofer (peavey scorpion 10), you can build a box: 36" high X 14" wide X 18" deep. Use 3/4" baltic birch or MDF to build the box (or get a carpenter to build it). In the box, make a hole for the driver at ear level, and another hole (slightly away & down from the driver) of diameter: 4.3". This second hole can be 4 " or more from the ground.
For the tweeter, you can use either a horn configuration, if you know how to calculate and build one, or alternately, just use a dome tweeter. Crossover freq will depend on the woofer curves. Make sure the efficiencies match (in other words look for a tweeter with eff close to 99 db). PArts express may have them. (www.parts-express.com)
hope this helps. tell us what you did and how it turned out!
