Review: Martin Logan Odyssey Speaker


Category: Speakers

The speakers I were supplied with came from my local ML dealer and had already been broken in by the store manager in his reference room.
My listening selection was varied to say the least, so I will list my selection:
Ry Cooder - A Meeting by the River
Loreena McKennitt - The Mask and the Mirror
Enigma - MCMXC a.D. (limited edition version)
Depeche Mode - World In My Eyes/Happiest Girl/Sea of Sin (CD single)
Prokofiev - Romeo and Juliet
All the above were CD pressings, I tried a number of virgin vinyl audiophile records, but was not impressed at all. More of that later!
My room size was 22 foot wide by 35 foot long, this is my sole listening room and I was able to place the Odyssey's in a number of different positions ranging from experimenting with distance from corners and walls, to various toe-in settings.
Personally, I found these one of the most coloured speakers I have ever listened to. To describe their performance and sound could be likened to listening to the mid and treble frequencies through a metal tube, and the bass (which is user adjustable), ranges from flat and uninvolving to booming 'in-car' type response.
The Depeche Mode CD is a high quality USA pressing only available in the UK on import, the production on this is excellent and I use it regularly to test a systems ability to drop in the low frequencies, plus their speed.
It was an extremely painful listen on the Odyssey's with this CD, the material sounded weak, flat, and mid's were over emphasized.
I did not feel with any of the material that the Odyssey's provided any great detail or soundstage as they seem to be designed to provide their own type of sound.
If fact, when I returned them to the store manager and provided my feedback, he said this was a common response with ML speakers and althouygh he has them set up at home and loves them, he seems to one of few people who enjoy their sound.
It's really difficult for me to say what type of music or system these speakers would be suited in, they seem far too coloured to allow source components or pre-recorded material to shine.
As for my vinyl replay system, once again, just as with the CD material, the sound was metalic and mid's were over emphasized so that the sound at best appears to be firing at you down a long metal tube.
My recommendation is to set them up like I did in your own surroundings with your equipment and music and try them for yourself. At $6500, there are far more involving and less coloured speakers out there, and at a fraction of the cost. Personally, it's going to take an army of ML staff to audition one of their speakers again!

Not sure why this was revived after 10 years... But at any rate, the stock Odysseys are very colored in the entire bass section, and by a very wide margin by today's standards, while also possessing panel colorations due to audible support pillar vibrations. All these issues are also apparent with the Prodigy as well.

Thankfully, all of them can be fixed by modifying the crossover and strengthening the support structures. The results are truly spectacular and worthy of using the best electronics with them.

Here are the relevant mods/threads I authored:

1) Crossover http://www.martinloganowners.com/forum/showthread.php?12761-Modifying-the-Odyssey-crossover-my-adventure

2) Structural http://www.martinloganowners.com/forum/showthread.php?13791-Taming-resonances-in-the-Odyssey

3) Woofer attenuation http://www.martinloganowners.com/forum/showthread.php?7437-Odyssey-mod-woofer-damping

Others have taken the crossover mods to yet higher levels, like Ps68's Spires, with their own structural mods; see http://www.martinloganowners.com/forum/showthread.php?9600-Spire-with-External-Crossovers-amp-Electronics.

With these modifications plus a sub, all these speakers approach the Magico Q3 in performance, and clearly outperform the Summit X and CLX (the latter would also benefit from similar mods).

From a tonal balance perspective, see the graph at http://www.whatsbestforum.com/showthread.php?2740-ack-s-system-end-of-round-1

The bottom line is that these are highly tweakable speakers with spectacular results.
Addendum: you may notice that the crossover redo is based on the same Mundorf CFC coil inductors, Supreme capacitors and M-Resist Supreme resistors as the Q7 - long before the Q7 even existed. I went further and replaced the binding posts as well with all-copper Mundorf M6 (a perfect shoo-in). I would recommend these products for just about any speaker. The total cost of all mods, and considering how complex the O's crossover is, is well below $10K in parts, current prices.
I know the thread's a little old but I was wondering what amplification you use for the Odyssey's ack. I'm in the process of redoing the crossovers and finding some granite to do the damping mod as well. Thanks for the work put into all those threads, quite impressive results as well.
