Used Martin Logans

I have owned upper evolution series dual powered woofers 
you unplug panels and vacuum once a month rule of thumb
xover parts are average at best ,I modded them  and after sold them this was my 2nd or 1st was the request , a bit to polite on top sound labs is 👑 king of stats they have detail and punch 
but are Big .  Buy a spatial audio labs x3 or x5 are great stat like speakers being very good open baffle speakers .

Actually are very few of the higher end Martin Logan's on the market. People tend to hold on to them a long time.

They are hard to drive because of their impedance dip in the treble so you need a superamp that can drive sub 1 ohm loads in the treble but if you can manage that then they are worth the time and effort to get one but you will lose some body to the music because of their electrostatic nature.

Where is this " see a ton of Martin Logan speakers for sale at about $1500."

I just see 1 page of assorted ML’s? There is a handful of lower end entry level models, is that a "ton?"

I picked up a pair of Theos not long ago, when there wasn’t any listings for them. There is a pair right now for a REALLY good price.

Perfect for someone like myself, who is just curious about the ML sound in their setup. Great speaker for the money. The seller has dropped price a couple of times.

"They are hard to drive because of their impedance dip in the treble so you need a superamp that can drive sub 1 ohm loads in the treble but if you can manage that then they are worth the time and effort to get one but you will lose some body to the music because of their electrostatic nature."

All that stated above may be "technical rule" on paper, but subjectively, they sound fine on both my $250 Receiver from 2002 and my 70 watt tube amp. They are not hard to drive.

What is missing is the lowest bass, but subs take care of that. I could live with the ML sound, but it would be the current Renaissance/Impression level $$.

Going back to my sealed cabinet Operas. Anyone ML curious? Perfect gloss black-beautiful to look at and hear.

ML’s electrostats are the only curvilinear planar speakers I’ve ever seen or heard. Their curvilinear design translates to line source imaging—the holy grail for image freaks like me. I have a pair of ML’s least costly model (EM SLs) coupled with a single ML Dynamo 800 powered sub. And although they may fall short in shear volume output, they do just fine in my small listening room.

In short, I wouldn’t trade them for any speaker system at anywhere near the $3,100 I paid for my factory sealed samples.
