BEEFY tweeters

[Haunz 10+ year member]

I need some heavy duty tweeters for my car. They will be highpassed around 2.5kHz with about 100 watts @ 4ohm on tap. Budget is $200 max.

Right now I'm looking at the Morel CAT 378's but I'd prefer something with a lower DCR for the most headroom from my amp.

Anyone have any suggestions ?

Mb quart dtk-30's are rated @70w but I have mine off a T400.2 with no problems but you will have to cross them over @ around 3.2khz, I scooped mine off ebay for around $50-$60 iirc. They also included some crossovers that look quality but I never hooked them up just used the ones I had in already.

Check out the Crescendo bullet tweeter.

why does beefy mean bullet? bullet tweeters are fine in low end PA cabinets.

Morel has a nice selection of tweeters with high power handling. Most of the models i'm thinking of are out of your budget.

Morel MT-22?

Because "beefy" when it comes to a tweeter means high effeciency, end of story. Power on a tweeter is a waste. How big of a coil do you think a driver that is only 1" or .75" across has? The DCR being lower wont' help, tweeters on a constant 20 watts or more will go poof pretty quickly. Very little power is actually sent to a tweeter on a regular basis so that's why you can put a 70 watt amp on one and be safe. The spectral breakdown of music will not usually call for massive tweeter power handling. However, if anyone wants to test my theory, go get a 0db test tone at 3k or so, get a decent aftermarket hu and go town on it, I bet you'll find the tweets either a.break after a minute or so, or B get FAR louder than you thought they could.

Anyway back to the main point of my post. High effeciency tweets are the way to go. A bullet tweet really isn't that bad, the phase plug can help control directivity. Crossfire the tweets toward the center for best results. This lets the tweet furthest from you be more on axis, so you get a more balanced response. Most low end PA cabinets use better drivers than most CA brands. The only major difference is pro audio people do it for a living hence they arent' stupid, they won't pay for 500% mark up on relatively low quality drivers. Anyway this is supposing he's trying to keep up with a SPL setup which since he's packign 4/0 gauge lol, I assume he is. Nothing morel makes will be heard over 150db's of bass.

I ran my Selenium ST350s in my van at 150rms each. They screamed.

you had alot of drivers in the van IIRC. What amp were you using for that? Lol forgot to quote I'm talking to Gmonk.

I'm not sure where you are going on that one.. I've got about 100 'instantaneous' watts of power on hand at 4ohms.. if you want to do the math on that go ahead, but yea I'm sure the tweeters will see less then 20 continuous watts of power..

The sub section is a pair of 15s built to be low end monsters in a sealed box running with about 2kw of power... probably only hitting low to mid 140's, but can play nice and low... overall the system is loud as stink but I need some tweeters that will keep up...

I will check out everyones suggestions !

For the price, you cant beat the Crescendo bullet or the Selenium ST200. Both are around $20 a pop and sound great and get real loud.

Just be sure you have some mid to back it up.

I remember years ago a company made a tweeter that's like 10" in diameter, the biggest dome tweeter ever made? Forgot what brand and I can't find it on the internet.

I know Audiopipe makes a 6" bullet tweeter.

Your description reminded me of these but they're definitely woofers. Not sure if they're the same thing you're actually talking about. It's like an 8" coil, though!
