Just a thought, but if an equaliser is a bridge too far you could bung a Quad 34 in front of the valve amp. The 34 has a very good (and transparent..) bass control that might take any remaining bloom off the speakers.
Would be handy if there was an AoS member in the neighbourhood who had one (or something equivalent) to try ....

Alternatively, the Musical Fidelity X-Tone is one of the least intrusive ways of altering the tonal balance and offers +/- 9db adjustment, which should be enough. They are hard to come by though, people hang onto them.
I rebuilt my ESL's about 30 years ago, no expert, but I think a critical thing for sound balance is the EHT going to the bass units and treble unit. A bit difficult (and dangerous) to measure, I used a GEC high voltage probe.Quote:

EQ belongs in the trash bin. I fecking hate them.
S.
I'd only use digital EQ if there was no option but in this case I suspect there might be no option. It's not purist I agree but it won't degrade sound quality and it will get rid of the bass boom. Bass boom is worse than a bit of digital EQ surely?
Yup . . . deffo.Quote:

Mine sounded sublime up there pre-service . . . but I got greedy and assumed the service would improve upon that yardstick . . . .Quote:

They still do sound fantastic, except when a sub 200Hz bass note comes in and messes everything up.
I did try a few things last night - more absorption material - raised 20 cm - moved forward - moved back . . . but still the boom is there.
Might give that EQ a try as a last resort otherwise I might well be looking for speaker recommendations . . .
But, where do you go from a good sounding pair of 57's?! . . . .
I've had horns up there too quite successfully (Loth X) but something tells me its likely to have to be a compromise . . .
