Hi, Can I use / connect the dr z brake lite to the 3.2 ohm speaker of the fender vibrochamp reissue 2021?

I'm pretty sure the Brake Lite and Air Brake are 4-8-16 ohm compatible, but I wouldn't suggest using it beyond that.
Outside sources (non-verified by Dr. Z) have postulated that the amp pretty much "sees" closer to 8 ohms regardless of the speaker itself when using the Z attenuator. If true, then your Vibro Champ would be "seeing" an 8-ohm load in its ~3.2-ohm output. It will work, but probably not ideally.

Hi, Can I use / connect the dr z brake lite to the 3.2 ohm speaker of the fender vibrochamp reissue 2021? While that speaker may read 3.2 ohm resistance, the load (impedance) is four, which is merely an approximation of the average expected load. If the Brakelite is built to handle a 4 ohm speaker, you should be fine.

I have got an answer on my email to drzamps:
“” Hi René, We do not advise you to go lower than 4 ohms with the brake lite. Sorry to disappoint,

Just to follow up… I very much doubt that the impedance rating of your speaker is 3.2. Resistance readings are never the same as impedance rating, and always lower. You very likely have a four ohm speaker.
Alternately, you could put a 4 ohm Alnico WGC 8” speaker in it. It breaks up and compresses very quickly.

I just did a quick lookup and the new reissue comes with the Celestion 10 30 speaker. The back panel of the amp says “3.2 ohms minimum”. The Celestion website says that this speaker comes in impedance of 8 & 16 ohms nominal and both have DC resistance of 6 ohms. Id research the speaker more as I have a feeling it’s one of the standard Celestion models noted above.

Apparently Fender had Celestion make them a special version of the Ten 30 — from fender’s vibro champ page: “We partnered with Celestion to create a 3.2 Ohm version of the Ten Thirty speaker with great tone and increased bass response.”

At least now we have the answer I guess the original ‘68 VC had a 3.2ohm speaker? I suppose Fender wanted to use a “correct” OT so needed the original impedance speaker.
