You want to hear a funny story? I was in Dallas for the weekend and went to a Magnolia store hoping to hear the ML 15A but the largest they had was the 13A like you just purchased. The salesman I spoke to was telling about his customer with new 13A's from Louisiana and how he might be going over to help setup these speakers and the ARC tuning. What a small world it is!!!

I own a pair of Summit X's which I also bought at a Magnolia store 3 1/2 years ago. If you would like we can speak via email or phone sometime and I can offer a lot of advice for getting the most out of these speakers. To be honest I was amazed at the sound of the 13A in their store which was driven by a Arcam receiver vs my speakers with my McIntosh system. The 13A has some serious potential for greatness.

Small world indeed!!! Was the salesman Mitchell? he's been the main guy I've used over the past 2 years with stuff. Its the Park Lane location. Right by Northpark Mall.

Yes would love to share info with you and would be grateful for any insight you can offer...

Tim.......One issue that immediately jumps out at me is the left channel woofer is almost completely blocked from the sweet spot by the couch. It is most likely acting as an absorption panel to some degree and is certainly altering the low frequency wave launch. You commented that this particular arrangement is how it had to be in this room and I understand architectural restrictions often dictate speaker locations. Still, something needs to happen to get the speaker from behind that end of the couch, perhaps shifting the credenza and the speakers a foot or so to the right. Don't be afraid to move the speakers a bit closer to the back wall, perhaps as close as 12" to gain some low frequency reinforcement. You may want to try moving the couch down the wall another foot or so, and move your sweet spot chair closer to the wall behind it by the same distance. It will be a trial and error exercise. Don't be hasty with your adjustments. Spend some time listening after each change in speaker and/or furniture location is made.

Excellent suggestions Dan. I can do that. I have room to push things back a bit. Thx!

With all due respect Dan that is not a good idea. Logans, like all di-poles need room to breath. They always sound their best when 'out' from the wall, 4-6'

Tim, it's tough to tell from the pics but another area to address is the rake angle, try bringing them (incrementally) closer to vertical. This is in relationship to your seating position in your chair.

Dave.......My experience with planar speakers is limited to dealer show rooms so I have little hands on experience with them. I was thinking more about the depth of the woofer cabinets only and how close to the wall they might be able to gain energy in the bass region. I hadn't considered that the panels radiate from the rear. Thanks for pointing that out.

Timobi,

Congrats on the Expressions! I'm thrilled with mine!

As Dave pointed out, ML's need to be AWAY from the front wall (ideally 3 or more feet, if possible). That keeps the rear sound wave from reflecting back and "smearing" the front/direct wave. For optimizing the bass, wait until you have a good 100+ hrs playing time, then run Anthem Room Correction. If you're still not happy, you can manually adjust the bass settings (and mid-bass toggle), or play around a bit more with speaker positioning... finding the best balance of soundstage depth and imaging (midrange and highs) vs. bass.

If still unhappy, I suggest measuring the speaker/room response with something like XTZ Room Analyzer, Omnimic, or REW. It's possible you could have a major bass null in your "sweet spot" (as I do) which might require rearranging the speakers in the room, and/or adding a sub (or two).

For more advice, hop on over to the ML Owners Forum and post your questions there... http://www.martinloganowners.com/forum

What if you place acoustic/diffusion padding on the wall behind the speakers? Would that help? I maybe in a similar position to need to do this.

Really appreciate all the suggestions. I did move my sofa back about a foot. Just shifted all the seating furniture down about a foot. I tried moving the speakers closer to the wall but thought the sound wasn't as immersive.

I got in another 10 hours of break in today while I was at work. I know this is a work in progress. And I know lots of rooms are far from perfect. When I see others pics I often say how are they pulling that off LOL. So there will be tradeoffs. I just want all the sonic glory of the ML's panels as well as getting the most and best bass I can get. Hahahah don't we all?
