Thread: questions on tweeters

most car speakers are 4-ohm, some higher end ones are 2-ohm. 8-ohm is common for home speakers

Most car stuff is 4ohm, whereas the PE drivers are typicalls 6 - 8 ohm. If you know what you are doing, you can potentially piece together a system that will cost significantly less than a store-bought product. I built my own component speaker system from PE for ~$100 with some higher quality caps, inductors, dayton tweeters, and audax aerogel midbass. It's 6 ohms, but runs off my amp just fine. But if you are adding a tweeter to an already designed crossover network, then make sure the impedance matches otherwise your freq curve will change.

that's quite awesome!

that reminds me, i need some new mids....

alot of people have used large format tweeters like that. IMO, the largest hurdle to overcome is mounting it-- because they are just so big--once you get it mounted though, the change in resistance can be compensated for with different settings.

Yea most of the PE tweeters are huge. Take a look into the Dayton ND20FA tweeter, that's the one I use. I picked it because it's very small and you can mount it from the surface.

that's very nice....but.
it's 6ohms. my crossover came with 4ohms. so what do i need to do?

I run Selenium tweets and mids in my "monster PT" they are 8 ohms and very efficient, I run them off of a 4 channel amp 115 per side but less since the 115rms is 4 ohms, they get very loud!

I also run Dayton mids and Vifa tweets up front, but they are 4 ohms mdels.

8 ohms tweets are fine, as long as you keep the crossover point safe for them and watch the efficiency of them, usually pretty high.

can i ask at what freq did you cross it over?
