Perhaps a cheap used Two Notes load-box, with 3-position attenuator - would get you closer to true bedroom levels.
I agree that my friend’s HRDeville 40W with a Quadraverb on the loop, still needed a little volume to get a nice sound from the speaker.
I love my Sequis Motherload Elemental. With bargain prices now on HR stuff, it would be worth buying a Sequis too and keeping it for life - through successive changes of amps. But you have to get over the speaker’s lo-level inertia.
My Palmers are now 40 years old, and I’ve had the Sequis for 8 years.
I haven’t miked an amp up in 20 years or so, and even then it was under layers of quilts and blankets!
