Hey! I know an application for attenuating speaker level to line level!One Carver Z coupler. In the heyday of Carver, this was used to sell amps to those who wanted to add more power to a stereo receiver. I bought it in a closeout sale and has been sitting in storage for decades...

Was hoping it had more to it (maybe transformers?), but was pretty underwhelmed after I opened.

Not really a need for more than resistors for an audio attenuator. A transformer just adds the potential for picking up more noise and introducing ringing. I forget exactly the circuit, but IIRC it used a H-pad or similar so would work with bridged amps. More than one audiophile (tech) has blown up an amp with a simple attenuator that grounded both (-) outputs in a stereo pair, letting the smoke out of their amp...
I'm looking forward to your subjective review when you're finished!Just finished servicing this two channel beauty. Impressive power curve once I’d blown the crumbs out:
