IS THE MARTIN LOGAN Renassance 15A worth the $10,000 higher cost than the Expression 13A

Thinking of buying a pair of Martin Logan's electrostatic speakers. I heard the 15A and loved the sound. They are $10,000 a pair more than the 13A. Is the difference worth it? Has anyone ever compared these 2 speakers?
 Why not listen to the 13A's yourself? Is there a store nearby that carries them?
Yes there is a store close by which let me hear the 15A's, which sounded great.They only had the 11A's which I could compare them to and there was a night and day difference between the 2. Just wondered if anyone was able to AB the 15's and 13's.

I auditioned both the 15A and 13A. The 15A has a wider and taller panel, with complete vertical orientation, so slightly larger "sweet spot" and perhaps a tad deeper bass. Midrange and highs essentially no different. IMHO, the 15A is ideal for a large dedicated listening room, although I can’t honestly say you get $10k improvement vs. the 13A. I was replacing ML Summits, so went with the 13A, as their size was better in my family room. Of note, I’m using Summit X legs on the 13A’s, to achieve an essentially vertical orientation (also raises the speaker a couple inches). I also have two ML BF210’s, which are now overkill given the improved bass performance of the new Masterpiece line.
   Sleepsurf, I am curious. I have Summit X's. Did you use the spiked legs on your Summit X speakers, and what kind of difference did it make in the sound? Thank you for your reply
Hello Sleepysurf:

Thanks for your feed-back. My listening room is 24' x 24'. Do you think the 13A will get lost in that space? What is the size of your listening room.

Scorpio... I purchased the Summit X spikes from ML for my legacy Summits, as Mids and Highs are very sensitive to "rake angle" (i.e. tilt) of the panel.  The default angle for Summits and Expression 13A's is ~5°, but using the Summit X legs, I've adjusted mine to 1°.

Samgar2, my family/listening room is 17' x 21' with cathedral ceilings, and adjoining 18' x 14' kitchen, so total ~6400 cubic ft.  You can see a pic here...

The Expressions would likely be fine in your room, but depends on overall acoustics/furnishings.  If it's a DEDICATED listening room (or Home Theater), you might still consider the 15A's if you really want larger scale sound (and appearance).  Depends on budget +/- wife or SO acceptance factor!
Thanks again for your comments. I am strictly 2 channel but like a large sound stage. That is why I am trying to justify the large price difference between the 13A and 15A. Yes, my wife would prefer the smaller speakers, however it is my man cave so her vote has little merit! These would be a second set of speakers in the other 2 corners of the room. 

What did you decide? I am going to compare the two this weekend.
Good   Morning Gadawg58:

Still have not made a decision, however I am leaning towards the 15a since I have a larger room. I wish I had the luxury to compare the two. Please let me know your thoughts once you have heard both. My feeling is that if I buy the 13a it will save me some money, however  it will have a smaller sound stage and I will wish I had the larger model.


I have listened to the Rennaisance's before. They are very impressive; and very large. Ultimately, your room size should be the main deciding factor between the Rennaisance and the Expression. In a nutshell....

If you have a fairly large room, and if you sit a bit further back, and if you want the maximum depth in soundstage/image, and if you desire that slightly deeper bass response, and if you need that extra 1 db of efficiency, AND if you have the cash.... then consider the Rennaisance.

If you have a moderate to medium sized room, and if you sit a bit closer, and if 24hz is deep enough, and if you don't mind the slightly lesser efficiency, and you want to save that extra $10,000....  then consider the Expression.

Also, bear in mind that the ARC technology is highly effective and is available in both of these models. It really helps to iron out a lot of the acoustical and room placement issues common to electrostats. I saw a demo of this technology performed by a ML rep at a very popular dealer in Canada. I couldn't believe the difference!
Hello Pontifex:

Thanks for your feed-back. I am wondering what you would consider a large room. My room is 26' wide by 22' deep. The room you heard the 15A's in, was it larger?  I would be sitting 12 to 14 feet from the speakers. Do you think the 13A's would seem lost?

Samgar2,  You can't go wrong with either speaker but with the size of your room the 15A's would be best.  I had the 15A's in a 18 x 24 room and they sounded awesome.  The 15A's have a bigger sound which is why i bought them and  I liked the way they look better then the 13A's.   However, they are a big speaker and my wife said "x!@#+^!" when she first saw them but learned to appreciate their modern aesthetics.  In your case bigger will be better.
