Paul Speltz Zero-Box Autoformer With Tenor OTL

Hello everyone,

is there anyone using Paul Speltz Zero-Box Autoformer with Tenor OTL and can give a full user experience please? My concern is whether the PS Zero Autoformer will degrade the extreme frequency of what the tenor the best for.

The speaker by now with the Tenor is Rockport Antares.

 

Thanks in advance for all the input.

I’ve read numerous reviews on these as I was considering them at some point to for my setup and the reviews were very positive. There is also a substantial window to return if they don’t help. In my case, I spoke with Paul and he recommended trying other options first.  He was very friendly and responsive via email and then phone.

I tried Speltz Autoformers with Atma-Sphere M-60 OTLs powering 91 db flat 6 ohm speakers. Thought they significantly degraded the sound and returned them.

You should have enough power for Rockports.

They very definitely do not degrade the sound.
