My next effort is to try them (my small collection of FRs) boxless - OB. I'll need low frequency support for that, which I'm hoping to supply with a pair of 18s in H frames. I'll need Xover for that, which will probably come from a second Zoudio amp and its integrated DSP. I'd like to do it at speaker level with passive, but the inductor is costly, I assume.

I think that by using the drivers rear radiation to enhance the spatial presentation, while simultaneously crossing it so it doesnt have to make any bass at all, may be a good way to go. I can only build it and see!

Put an acoustic low pass filter on it.

Could a similar effect occur using, say, a copper sheet adhered to the back and bottom square area of the speaker cabinet, connected to the (-) terminal?

Just trying to think of something with close to the same surface area, but having a more reliable electrical connection (solder).

Perhaps with the jar of metal scrubber, using a large alligator clip then filling the jar with oil - it would never have an electrical contact issue. My friend used to show off a jar full of machined brass chips in clear oil - they looked like gold for years!

Dear jjasniew,

I tried 0.4mm and 3mm copper plates, but the high density brass scrubbers gave better sounds.

And I don't use oiled scrubbers, because it will be difficult if the bottle breaks.
