Replacing Tweeter in PSB Alpha

[K-Money]

On the weekend I picked up a set of PSB Alpha's for $10. The tweeters had already been replaced with crappy non-stock tweeters. The seller threw along some Motorola KSN1039A (according to my research) tweeters he said I could swap out. He said these I could just wire in, but if I went with better ones he mentioned needing a capacitor/crossover.

Is that the case? I'm a noob when it comes to this but my understanding is that the crossover circuitry is already in the speaker. If I get different tweeters can I just wire them in to the existing wiring, or will I need a new crossover as well? I'm going to try the Motorola's, but am open to reasonably priced (under $50) suggestions for an ideal tweeter for this speaker.

Thanks

Welcome to AK! Which exact Alpha model do you have, and do you have a pic?

I wouldn't replace those with anything but the original tweeter. Anything else wouldn't work properly without a complete crossover overhaul. Those particular Motorola's are piezoeletric tweeters that don't quite behave the same way (electronically speaking) as typical tweeters.

Thanks for the reply. The former owner thought they were Amazing Alphas from the 90's, although he bought them used as well and he wasn't sure. He replaced the front grills.
