    Unbelievable Sound!

    • My Best Buy Premier Silver Member

    I originally came into my local Best Buy Magnolia HiFi center to listen to another pair of speakers. These little gems were not even on my radar. The look of the speakers lead me to believe they were several times more expensive than what the actually price was. A beautiful piano gloss black finish and speaker grills that dictate there is something sinister underneath. Needless to say I was shocked when these were fired up and played sound that was just amazing. I did not believe that the bass response from these and even looked for a subwoofer that my have been on at that time, but these little gems were the only speakers playing. The Highs, Mids, and Lows from this speaker seem to defy what should be allowed to be produced from a loud speaker this size and at this price point. I took them home and now am a proud owner of a pay of ML Motion 40. They complement my system well and I still cannot stop staring at these beautiful works of art. Amazing accurate bass, solid Mids, and High frequency response that will amaze you, all from one sexy package.

    Word of caution with these speakers

    • My Best Buy® Elite Plus Member

    I have these hooked up to a Marantz 5008 receiver, which is a pretty respectable piece of equipment. After about a month it started shutting down into protection mode while using these speakers. What I found out was (by Marantz) that these speakers, in fact all ML's are, truly 4 ohm speakers even though they say they are compatible with 8 ohm receivers. In short they are power hungry and your receiver will try to push them at 4 ohms eventually causing clipping, overheating, etc. One solution, Bi-amping, Ive never been a fan of that but in this case it worked. I immediately noticed a difference, it was a WOW moment for me, they outperform my B&W's and Def Tech super towers and this point. My Marantz seems to be running cooler now as well.

    Superb Sound!!!

    • My Best Buy® Member

    Excellent speakers, i love the sound the motion 40's produce, i have tried many different speakers including ML ESLs, B&W CM9s, Polk RTi line and many more, and i can say without a doubt that these speakers are the best (at least to my ear) The only other speaker that sounded clearer and a little more detailed to me were the ML ESLs, but they have a very narrow "sweet spot", and outside the "sweet spot" they sounded muffled to me. If you are looking to buy new speakers definitely go to your locac BB Magnolia center and hear them out. You can check out my video of the Martin Logan Motion 40s on youtube.

    Astonishing sound...remarkable depth and clarity

    • Verified Purchaser
    • My Best Buy® Member

    When I first disconnected my Cerwin Vegas and Big old Pioneer CS907's, I felt a little sad and awkward as if I were making a mistake with my system. Once my new ML's were out of the box, I felt an overwhelming sense of hope as these speakers look and feel fantastic...even my girlfrined agreed. I fired-up my Amp and selected 'Anastasia' on the new Slash CD. I admit that I was not prepared for the fullness and depth that came from my stereo system. Immediately I was filled with joy and a sense of achievement that my decision to buy these speakers was probably the best decision I could have made. I've listened to some pretty high end systems and mine sounded as good as a 30K$ equivalent. If anyone should ever ask me what speakers they should buy, I will not hesistate to tell them to buy these ML's. Happy listening!

    Simple amazing, just amazing...

    • My Best Buy® Elite Plus Member

    I originally went into BB Magnolia to purchase a pair of B&W 683 S2's for my home theater setup. My budget was in the $2k range so I knew I could get a great pair of floor standing speakers that would last me for years. Now keep in mind that before I settled for a pair, I stopped by Magnolia during lunch break for an entire week before making my decision. I started off with the B&W 683 S2's paired with a Pioneer Elite SC-81, the B&W 683 S2's sounded warm (which is my preference), full and powerful as expected. I then thought to myself, why not try the Motion 40's? I've heard nothing but the best from reviewers online who actually them paid with a more than capable receiver. So what did I do? Switched the setup over to the Martin Logan Motion 40's and my ears were blown away! The sound reproduction coming from the Martin Logan Motion 40's were just insane and out of this world, I couldn't believe what I was hearing! What I loved the most about the Martin Logan Motion 40's were the high crisp details that I didn't even know existed until I heard the sound reproduction straight from these awesome speakers, compared to the B&W 683 S2's it was a no competition, the Motion 40's wiped the floor and it wasn't even close in my honest opinion. With that said, I bought a pair, hooked them up to my Pioneer Elite SC-71 AV Receiver and couldn't be happier with my purchase. I initially thought I'd need my subwoofer but with these babies bi-amped there was no need for a subwoofer at all. The Pioneer Elite SC-71 provides more than enough juice with it's Class-D amp. Go buy these speakers, Martin Logan outdid themselves on this one, truly one of the best speakers that I've ever heard in my life!

    Great speakers, at a fair price!


    Updated, and UPGRADED, my entire speaker set up. Went from some Klipsch Heresy IIs (mains) and non-timbre matched Klipsch center (KSF C-5) and surround (SS-1) speakers to a completely new Motion speaker set up. The Heresy speakers will be missed for their classic rock sound, but the Motion 40s are my new love. It is like comparing a 70’s muscle car to a finely tuned sports car of today. Both have value, but the demands of today music and HT requires high-performance machines. I bought the Motion 40s (mains), Motion 50XT (center), Dynamo 700 (sub) and Motion FX 5-1/4 (surrounds) all in one go. The speakers are being driven by a Marantz SR7005 (AV receiver), which seems to be very good match for Martin Logans. My listening is 70 percent music (rock, blues, 90’s alt and some jazz on Sunday mornings) and 30 percent TV/HT. Okay, for the quick review: The recommended break in period is no joke. After 50+ hours of two channel playback, the sound warmed up and some harshness in the tweeters began to relax. I think the center channel took the longest. Bi-amping the Motions 40 is a “must do” unless you have some sort of high-end, high wattage power amp. The Motion 40s will thank you for removing the jumper clips! Some may want a more power subwoofer than the Dynamo 700 if you like to cause structural damage to your house during movies. But for me, the sub is more than adequate. The piano black finish is a very nice, adding a tough of classic to any living space – wife accepted! Bottom-line, I am completely happy with my purchase. Years of listening pleasure are ahead! The only downside with these speakers, you may start seriously considering a high-end pre/pros arrangement to maximize the capabilities of these beauties. I am!

    These are the best looking speakers on the market but that's not why I bought them. I bought them because of their clarity. I actually listen to movies and music at a lower volume because these speakers sound so clean. Well worth the purchase. I bought at Best Buy with a Best Buy Credit card and a 10% off coupon off of one item. Best Buy has these for 949 and online they are going for 999 but no tax. If you use. The Best Buy CC you get at least 4% back, and easy returns. I went with Best Buy because they were about the same price after all said but I didn't have to worry about shipping damage or return hassles. Ohh and instant gratification.
