OC25SC65 or ???

jhollanderjhollander
in DIY

I've got a project where I'd like to rear mount a tweeter in a hardwood baffle. The opening will be a 45 degree chamfer about 1/4 inch deep. I'll probably cross in the 5-6K range. The kicker is I need at least 90 dB at 2.83v. This would be an all Peerless project if I go with the OC25SC65.

I'm not that thrilled with the 3rd order distortion compared with other tweeters https://hificompass.com/en/speakers/measurements/vifa/vifa-oc25sc65-04

Any other ideas? Not a lot of space to hide a big flange or chamber in a 4 inch baffle width. I've already done a ton of projects with the ND20FB so that's off the table. I can't recall if the small AMTs have the same distortion profiles. The original tweeter was the Beston RT003C without the face plate until Craig dumped on it. :angry:

    Solen has the Airborne 4001 which has a very good distortion profile.

    Other than that one, I have used the small flange XT25 and liked it a lot

    Peerless XT25SC40-04 has NO flange and is 91db.

    EDIT: I have an extra pair of these. I'm not sure if there are distortion measurements out there, but I can take some if you want me too.

    TW030WA03/04 is an option. 4 ohm models, so sensitivity is there.

    Are the lavoce ones any good? Such as TN131.00, TN100.70

    Wavecor TW013WA01 is a cute little tweeter. I could measure distortion if your interested.

    XT25 or DX25 BG with the faceplate removed and rear mounted to the baffle with the adapter for the WG 148 waveguide?

    Good options here. Thank you. The aspirational choice is the TW030WA03/04, looks like the XT25 variants would be close on the sensitivity and the TW013 a little to low. I like the AMT idea. I'd really need to keep the Airborne x-o high. I'm trying to decide if the rectangular opening fits with the design.

    I used the TN131.00 in the speakers I had at InDIYana and SDC with the DIY sliced SB16PFCR-8s. I liked them quite a bit but they aren't necessarily better than the other ones being discussed.

    Ended up buying the TW030WA03. nice sale and great exchange rate :)

    I can’t find that model on Wavecor website.

    It's an "OEM only" model, not sure why Solen as some stock of them to be honest.
