DwaynesReview –
These speakers were very easy to hang and they put out great sound when coupled with my subwoofer for movies!

I’m using 8 of these as surround and height channels to match with the ESL-X and ESL-C front stage. I tried them as a 2 channel setup while waiting for the dedicated room to be finished and WOW! As long as you understand they play to 70Hz and aren’t expecting crazy levels of bass, these blew me away with the sound stage and clarity. Maybe because I paired the, with a Marantz AV7706 and Emotiva XPA-11 gen 3 amp they exceeded my expectations as I’ve only ever used AVR’s prior. Highly recommend. I purchased them when they were on sale, but feel they are worth the full price if you don’t want to wait around.

Excellent compact speaker. Big on sound quality and style.
Blurred –
Bought these to replace the front speakers that came with the 5 speaker martin logan set. I love ’em!!!! Great sound, great product from ML. Demo at bestbuy and hear for yourself
DCM401 –
Great sound in a nice compact design. Well worth the money
Jamie –
Excellent sound quality. Used these with turntable and albums!

I purchased these about a year ago for my front left and right speakers and haven’t stopped smiling yet. They are driven by a Marantz SR6014 receiver and paired with a nice Polk Sub since they are not made to pound out the lower frequencies. . Once the Marantz Audessey room calibration checked out the room and the speakers, the result is simply astounding. Don’t expect these to be a full range speaker, but when you drive them correctly, they are simply beautiful speakers. I have had them setup in 2 completely different room environments and they are simply fantastic. I suspect you do need a really nice amplifier to experience the refined and effortless sound these speakers are capable of.

I am I love with these speakers. I have the matching center. Can’t wait to pick up the sub
Tbone –
Amazing sound for the size. Remember to get banana clips for the speaker wire. I had a chance to listen to these in the sound demo room at a store with Magnolia. Try it if you want to check them out.
Robert –
Great product quality. Sound has good highs and lows while watching dolby atmos, and other surround sound modes.
LGdishwasher –
These speakers are fantastic!! Clarity is unreal. And they deliver a punch. I placed these behind us in the living room to give us a 5.1 surround. Definitely recommend.
Alboy –
Fabulous sound!! Plug and play into my receiver. Fits perfectly under the TV.
joeyjay –
Great sounds good to add to any stereo or surround sound system! Terrific tweeter and okay bass. You definitely need a subwoofer to make it terrific.
MusicLovers –
Bought these for use as the rear speakers to round out our existing Martin Logan collection. We love the fullness they add to music in the room. I was surprised at just how much bass they produce from these small speakers. The wall mounts are clean, but sturdy. While Martin Logan products aren’t cheap, they are built solidly from quality materials, reflect their commitment and exhaustive research for premium sound and are stylish enough to compliment even the nicest decor.
Johnny –
Works great. The speakers might of been a older model.
Satisfied –
These are nice speakers. However, I chose to return them and upgraded to Bowers & Wilkins 606 S2 speakers to match my current system.
Blawesome –
I bought these for rear surround speakers. I was a little worried I wouldn’t like them as I found a pretty negative review online. These definitely don’t sound as good as my Motion 60i’s but because these are really for special effects noises they are perfect. They definitely need to be crossed over at 80hz and you have to have a subwoofer with them. They also have a 1/4×20 lug in them as they are designed to be wall mounted. Worked perfect for our needs.
Retiredandenjoying –
I bought these (2 of them) to replace my old Bose speakers that I was using for my rear surround on my home system. What a difference they made. Everything sounds crisper, hearing things that I couldn’t before.
DIYJeff –
So far so good. I am using these for surround speakers with ML SLM-XL speakers for LCR speakers. They mounted easily, although it seemed a little tenuous. Just make sure that you have the key well seated in the speaker. Sound seems good, but nothing to compare it to in use. They look good and should compliment the SLM-XLs.
These were open box and everything seems to be present and no issues found.
Tslag –
Great speaker for surround sound speakers. Sounds great. Has the mounting screw hole for wall/ceiling mounting. Would recommend using banana plugs for these for a quick and easy connection.
Jso416 –
Awesome speakers!!!! So far even better than I expected.
Rocketman –
Great front surround speaker. Use with movies at medium volume. 8 ohm amp works with no problem.
ZXL7921 –
Best Buy open box item condition rating is a joke. Order two items both rated by BestBuy at excellent condition. Return both defective item.
inoracam –
These suckers sound so good you’ll be one happy panda (I assume pandas are happy). The depth of sound, the volume without any distortion, oh it sounds so so nice. Perfect for gaming, movies, or music. They are also aesthetically pleasing to the eye.
SamsungSoundbar –
excellent sound and vocal clarity from a small speaker
MusicLover –
I love the purity of the ribbon tweeters in the Motion 4 speakers. Since I like to feel the bass, I would only purchase them paired with the Martin Logan Dynamo 8 sub for a medium sized living room setting. The high end is delicate and smooth for acoustic music, but still have a decent edge for harder rock. I wouldn’t recommend for hip hop styles with explosive bass energy, but if that’s your preferred music genre you probably would be looking at this speaker anyway1
GrannyM –
The Geek Squad did an amazing job installing add on’s to our entertainment center. They were courteous, respectful, conscientious, very professional. The speakers we purchased fits well and provides adequate sound in our small living room. We are very pleased with the workmanship and products.
Timbo362 –
Great little speakers with a big sound fills my mind!
Kennygadawgadawg241241 –
I’m using these for rear surround sound in theatre room and they rock. Martin Logan are not the cheapest, but are well worth the investment.
Raul –
Really good speakers for the size. Honestly Martin Logan is one of he best ones
Nikekid –
These compact satalite speakers are really just that good fir the price. The folded motion tweeter gives you a crisp and airy sound with tons of detail. The sound stage is very large for this size of a speaker the ported mid bass has great low end that match some of the larger speakers in the martin logan range. If you do consider to purchase these get a subwoofer to help with the lower frequencies. These are a must have for anyone getting into speakers I cant give them any higher praise than that.
SlimSlow3 –
Sometimes good things come in small packages and these speakers are a true testament to that statement
Disappointed –
Great quality sound! Zero disappointment. Thrilled with the purchase. Worth every penny.
DPTreview –
Clear, clean sound. Using these as monitor speakers for edit station.
Abe1 –
Very pure and clear sound on low or high volume with crispy sound
Timothy –
The speaker works great! You can get away with one if you don’t have room for two or just prefer one.
Drew –
Didn’t have the opportunity to listen to the speakers in store when I got them at home they didn’t quite fill the space with the sound that was required for the size of the room.
TannerN –
Using these for my side surrounds and rear surrounds in my 7.2.4 Atmos system. Love the sound that the folded motion tweeter produces, very clean, clear and accurate. Great for home theatre applications
TimF –
Rear speakers pick up too much sound on some TV channels. On other channels, the mix is good. Playing music CDs give optimum quality.
AVdgo12 –
Excellent speakers, great quality sound.
Totally recommend for home theater application.
KevinM –
Sleek and compact at a reasonable price. Easily mounted to my wall and sound sounds great. Paired these with the center channel speaker for full sound enjoyment.
Mr4k2160p –
Love These Speakers I should have started this upgrade along time ago
tlg6532 –
I have the Motion 2’s for the surround back speakers so I bought these for the front height, much more detail than I expected which is a nice surprise. A good fit with my Martin Logan ESL’s so that is a definite bonus.
LovegloveZ –
Fantastic and wide ranged. These bookshelf spreakers cost less then most that can compete and dominate my soundstage. Capable of reaching every feasible level of decible and making full use of that range. I’m blown away.
Unknown –
love these speakers. have several of them in my house
Mark –
I love these speakers!!! Wall mounted a pair of these for my L and R channels. They look amazing and sound even better. My room is a bit on the smaller side, but these speakers fill it with sound.
The wall mount included in the box gave me enough space for banana plugs without the use of the extender. If you have larger clips and need to use the extender, you might want to find longer screws. Rounded tip 8 x 2 works well if you’re using the drywall anchor. I didn’t use the extender and went right into a stud so the included screws works perfectly.
The included wall mount does not allow for rotation or movement. It is stuck in 1 position. That isn’t an issue for me, but some people might want to be able to angle the speaker.
The template included makes installing on a wall super easy. I recommend a laser level if you want to make sure left and right are mounted at the same height.
SP00 –
But, the sound was not to my liking. I have used Bose, pioneer elite & Bowers&Wilkins. Prefer them over these.
KeithR –
Speaker wire connectors are awkward. Who’d design something like that? Almost impossible to insert stranded, bare, speaker wire.
BellamyM –
I am truly happy with the range of these little guys.
yawtwum –
Excellent heights, ease of mount, value for money.
