All New Martin Logan ESL X ?

So George, are you saying 400Hz is too high for crossing over to the ESL panel

.Yes, to me small narrow esl panels can’t go low enough, so the bass has to be bought up to it, and to me they don’t marry well at these very sensitive midrange areas, it’s a compromise but still very listenable.

The proper fix to me would be to have a much faster lighter cone 6-7" midbass unit to match the speed of the esl’s at 400-500hz and then have a 10-12" 10-12" bass unit below that at 150-100hz but that’s going to be complex and expensive.

The other fix is to have a bigger wider esl panel that can go down to 150hz like the Monolith and Neolith and then have a good 10-12" dedicated bass unit.

Cheers George

I have a friend with the latest Summit X, they are great and I would have these if I lived in a unit or town house, but they are well behind what my mod’ed Monoliths can do with sound staging, imaging, scale and lack of colouration ect.

Mine now, with especially with how my bass is now set up, is more closely related to the Neoliths than any other ML. esl.

And now they also have the latest tech esl panels which seem to be identical in dimensions and shape as the Neolith’s, just the foam segregations spars are at different distances, they may even be interchangeable with the M.L. Neolith.

This is why some of us own systems that are worth more than a our car, we seek perfection in the music replayed to us by our systems.

Sorry I look at it a different way, I do love the final result, when all gels and the music presented has no compromises.

But if I didn’t judge and analyze and repair, I wouldn’t have changed the bass driver in the Monoliths (and it was rubbish), I would just have just got onto the merry go round of changing speakers instead of owning the same pair now 15 years.

And sorry do find it hard to accept that a sub base driver with far more mass can combine in the critical 400hz midrange with the super light esl x panel, it’s fine to mix them down low <200hz but up this high to me is a compromise.

We will see what the reviews/ers say when they come out.

Cheers George.

Sorry no chance, the speed of an esl in the mids (400hz) is a compromise when mated with a slower dynamic bass driver, it's a price/size compromise there will be colourations, but will still be listenable if you don't mind. 
That's why the CLS/X and other full range esl's sound so coherent through that area. 

Cheers George

Like a baby Summit, I think the mids may be a bit coloured though as the xover is high at 400hz.

Where in the Summit it was 270hz, and even that to me was a bit high.

As I’m used to 150hz with the Monoliths and thats with a 24db/octave low pass on the ACI SV12, the factory Eminence driver was cheap rubbish, a very one note sound.

Cheers George
