Recommendations on small ESL speakers for tiny room

+1 on David Janszen

Maggies or ML. Take your pick. The Maggie LRS with a sub or two sound particularly good for the money.

I can read. I understand the allure of ESL. I get it. However, this limited space challenges all that ESL needs to perform well. This space speaks active. https://www.sweetwater.com/store/detail/SCM20ASL--atc-scm20asl-pro-mk2-6.5-inch-powered-studio-monitors Best of luck in your search.

I have owned Quads, ML, and Magnepan. Specifically, Quad 57’s, 2805’s, and 2905’s; ML Prodigy; Magnepan Tympani 1A, IIa, IIIa, SMG. Have just ordered Mag DWM and MMG-W for the HT.

Considering that you already own Sound Labs, I would not consider anything other than Quads. ML hybrids are OK for HT, but I found them disappointing for audio.

Quad 57's are a very musical speaker, but lack the bottom and top octaves of the new series, and also their clarity. That said, the best room I ever heard used 3 pairs of 57's, stacked.

The 2805 is much brighter than the 2905, which is quite mellow for an ESL, and the same size as your M545. Both can be significantly improved by a toroidal step up transformer and a better HV power supply, which I suspect brings it near the performance you already have.

Good luck - I’ve always wanted to try SL, but never got around to it. Maybe someday ...

Another thought - SL does custom work. Maybe they could do a 65% size, an M445?
