Default Cheap tweeters for a 15" woofer.

Hello,

I've recently made a 2'x2'x2' sealed cube and thrown my first pro woofer into it, a nice big 15" Behringer Eurolive 15W300A8, 300Watt @ 8Ohms. I must say that I'm amazed at how nice everything sounds giving this single woofer, with no other speakers hooked up, only half of its wattage. I've never had such full and defined mids before, not to mention this single woofer at HALF of its rated wattage is louder than most of my other speakers combined!

However I do need to get a proper tweeter box to handle the highs for this woofer. I want something that will be a good match for how loud this woofer is, as well as being cheap. I was thinking horn tweeters, but I don't know if it's worth it to spend the extra money on actual compression drivers instead of piezeo drivers.

I want to keep this little tweeter endeavor under $40, preferably under $20 if possible (not counting the wood for the box).

Any help is appreciated, thanks!

This MCM horn is big and cheap. MCM Audio Select 1.75'' Compression Horn Tweeter - 7.28'' x 14.37'' Horn 300W RMS | 53-1250 (531250) | MCM Audio Select I have a pair but have not put the hurt to them yet, someone on a forum measured their frequency response a while back and it was not too bad. $15 each!

Yes it's worth the extra money, 1 on 1 there is no comparison between a piezo and dynamic compression driver especially one with a non metalic diaphram, much cleaner and more detailed mids.

This looks interesting, not a bad price at all, however I see some not so good reviews on that site about that horn.

Okay then I guess I'll go with compression drivers considering it seems to be the general consensus online.

Did you expect good reviews on a $15 anything?
Cover it in some endangered species fur, ask $1200 for it and instantly all audiophools will start raving about it
Actual sound is irrelevant.

Actually yes, there some good cheap products. Look at all of the cheap full range speakers that parts express sells, most of them are pretty good and are loved by many here on diyAudio.

Hah, yes I agree, it's a shame how some people fall for buying some stuff.

Here is the thread on the cheap MCM

MCM 53-1255 & MCM 53-1250 Cheap Horns Click the image to open in full size.

The plastic horn is brittle, mine had a small chip on the corner when shipped but it was not a problem for my application. I am sure MCM would have replaced it if I asked.

So lets say I were to buy this. How many would I need, just one?

And what sort of box would I put it in (i'd like to to be separate from the woofer box, and possibly have 2 individual ones for stereo).

I re read your initial post. I thought you were making a single speaker cabinet. What is the use going to be?
