Replacement super tweeters for Pioneer CS99A

Scholl

Hi guys,

A friend has a pair of CS99A that has several super tweeters not working. Are there any current production replacements or does he have to buy used replacements?

Thanks!

Scott

Not a bad replacement... - Scholl 09:10:51 08/13/24 (1)
It might be a little lower SPL but not too bad.

  Replacing the original alnico tweeters with Chinese domes is a definite downgrade. Used original tweeters are available at reasonable prices on the big auction site.
Are you sure they're bad? Might be caps. - GRH 17:08:52 08/11/24 (2)
The highpass caps might be the real problem or also an oxidized pot if there is a level control.

  Very good advice! I used to rebuild/recap a lot of the CS series and found that the overwhelming majority of the time when a tweeter or mid is out it's fixed by a good recap. Of course I have seen drivers go bad, but it's pretty rare.
  If the tweeters are bad then I would shop eBay for some used ones that the seller tested and guarantees they are good.

Scholl, if diameter is 3 1/2", try Voyz PET-1918 Piezo Super Horn Tweeters as replacements. Got two as curiosity purchase for auld-school wood cab re-build. Remove that 3.3 uF electrolytic crossover cap, which is on negative tap(?). Add 2.2 uF x-over cap of choice & enjoy that crisp sparkle, which is atypical of most piezo tweets, once it breaks in. Utilized 4.7 uF Dayton polyprop x-over caps with vintage 10" Technics woofers for moi's two-way project. Voyz are designed for auto stereo, but work just fine in attaining a vintage vibe. ... 73s para Sactown

  These are the small tweeter to either side of the horn. Thanks.
