MartinLogan Dynamo 300 8" Stereo/Home Theater Subwoofer Each

Pros: Small Accurate Sound Inexpensive

Cons: None

Overall Review: For those who want clean tight musical bass, a quality 8" sub is an excellent choice. I use it through the preamp output of a 85-watt Peachtree Nova stereo amplifier to the RCA inputs of the sub. It is currently being used with Polk Model 70's and Klipsch WF-35's. I keep the sub positioned directly behind the TV, which sits on an open shelf type stand. I have a preference in keeping my subs centered and back a couple of feet behind my mains. I mention this because, despite seeing diagrams where a single sub is positioned to the outside of one of the mains, I find that not all bass is omni-directional and this gives me better balanced, room filling sound. I only turn the input volume about 25% up and have the frequency adjustment set to about 60 cps. The stereo is set up with a WF-35 and a Model 70 for each of the front mains, four speakers total in front and two additional Model 60's, powered by a separate small stereo amplifier in the rear. I have the rear speakers reversed, with the right front channel going to the left rear channel, ect. The four full range speakers in the front plus the pair in the rear provide a full room filling sound with a 2-channel stereo source. The key here is a full sound all over the room which provides a listening enviroment similar to headphones. The single 8" sub comes in whenever it is required to do so but in a tight musical way that fills in and rounds out the bass with a full and natural sound. The tower speakers go to 50 cycles on the WF-35's and 40 cycles for the model 70's (@ -3db), so a sub isn't really necessary for most music, but... a sub does enhance and complete the sonic picture. Understand that a large speaker and a powerful amplifier are not as important as the quality of the sub itself in a musical enviroment. This Martin Logan sub is a quality musical oriented sub. (One of Martin Logan's other subs has three 8" drivers in a single enclosure and sells for over $2k.) Today's "tower" style speakers typically offer multiple smaller drivers than speaker cabinets of past years. I have a total of 20 mid & low frequency drivers of 5 1/4" and 6 1/2". The smaller drivers give today's listener a tight sound that is well matched with an equally tight sounding 8" sub driver. This sonic quality much better than having a large boomy sub! Even with the "small" 75-watt amplifier, the Dynamo 300 will effortlessly keep up with louder volumes and still produce clean LF sound that has a punch but not a boom. Often overlooked in importance, is the ability of a sub to bring out bass at low listening levels. When listening to music like a jazz trio at lower levels, the listener hears the sounds of the lower octives of the piano, the mellow sound of the string bass and the gentle kick drum in a full pleasant natural balance. I keep my Dynamo 300 sitting on top of my Polk PSW505, 12", 300 watt RMS sub. I listen with my Martin Logan sub connected 85% of the time. Best sub for the money!

Pros: Price, Size, Frequency response, Power, Quality

Cons: Phase switch that only allows 0 or 180 degrees. A knob with some options for in between would be nice.

Overall Review: First a little background on my situation... I had a little Sony HTIB that I used for years. It had a nice little 6.5" sub that was powered by the HTIB amp. Well it stopped working and there I was with some good surround speakers/sub but nothing to power them with. I was able to scrounge up an old Pioneer receiver that my dad wasn't using, but of course most receivers do not power the sub, so despite being happy with the sub I had I was forced to buy a new one... I was looking for something affordable, small so that the WAF (Wife Acceptance Factor) would be good, and down firing. (My old front firing sub caused some serious rattling in the entertainment center and the only thing that made it stop was to turn it so it was up firing). So I really wasn't looking for something amazing, just any old sub that would pick up where my little satellite speakers roll off. Enter the ML Dynamo 300! Right out of the box I was impressed with the build quality. The box feels sturdy and solid. I wasn't going to be able to set it up for a few days, but wanted to make sure it was working alright and not DOA. So I got some cables and plugged my phone into it. Ran a few songs with good bass lines that I was familiar with. All sounded clean, tight and musical. Then I switched over to the frequency generator app on my phone. I wasn't expecting it to go too deep because of it only being an 8" and rated down to 32 Hz but boy was I surprised! This thing is fairly powerful all the way down to about 25 Hz and rolls off quite badly at 23 Hz. Not bad for a little guy! And even at 23 Hz the sub was still working hard and moving plenty of air, just wasn't that audible. I probably should have moved a few feet away from it to be able to hear, but I didn't think of it at the time... A few days later after getting it all hooked up the wonderment just keeps on coming. All these years I thought that I had a decent sub and was doing fine. This thing makes my old 6.5" Sony look pathetic. It can get all the walls and ceiling rattling if I want it to. I had no idea what I'd been missing all this time. I started watching movies that I was familiar with and skipping to scenes I knew had good bass, and every scene left me amazed at what I had been missing. This thing gets so much lower and more powerful! Huge improvement over what I had! I can't really compare it to anything else but what I've owned, and I'm sure there are subs out there that will put this to shame also. But for the price that I paid for it, I can't imagine a better sub. I can see myself buying a second one when the basement gets finished and the home theater moves down there, but only because the area will be larger. I think it will be extremely hard to beat the value for money on this baby. If you're setting up your first home theater or upgrading from a HTIB like I did, I highly recommend this sub. If you're used to million watt 18" subs maybe this won't blow your skirt up, but it sure did mine.

Pros: Works great and puts out terrific sound. Being bottom firing & bottom-ported, this thing sounds terrific when placed in the corner. The bass is projected around the room MUCH better this way, and sounds much more full to me. It's not a basshead's ideal subwoofer, but it definitely has enough oomph to shake my place up during explosions. It's only an 8" sub. The reason I wanted an 8 instead of something larger is because the larger subs tend to sound a little more boomy. Sure, I lose out on the low-end extension... But with two 8" subs I can get plenty of "hit", and I don't have to worry about it being too boomy or sloppy. The bass is nice and tight. I was originally looking to get a REL to go with my home theater system, but after hearing about these and their sale, I had to jump on em. Would rather a pair of 8's than a 10 anyways.

Cons: lowest-end extension is a little vague. These puppies can play pretty low and make it sound right if they're corner-loaded and properly broken in. Still, not as low as some of the other 8's in the audio industry(which generally cost much more)

Pros: This sub sounds great after breaking in. At first it sounded horrible but after several hours this sub will break in and sound absolutely amazing. It does get pretty low for an eight inch sub I can hear it all the way down to 14 HZ with the audio generator app I downloaded on my iPhone. This sub blends in perfectly with any speakers and is very musical!

Cons: Appears to Have the Same amp as the Pioneer SW-8 which is also a great sounding sub.

Overall Review: For the money I would recommend this Dynamo sub over the Polk PSW10. It only cost $20 more, or if you don't have the funds go with the Pioneer SW-8. It's cheaper than the Polk Audio PSW10 and sounds better! The Polk Audio PSW110 is a very nice sounding sub if you want a Polk Audio Sub.

Pros: I just bought this sub to use in my bedroom with an Energy Take 5 system and a Yamaha V373 receiver. After watching a movie, and playing several different genres of music, I have decided that this sub was exactly what I wanted. At only half volume, this sub provides a noticeable, very crisp and clean bass sound. I could not be happier with it for the price that I paid. It won't shake your pictures off the wall, but if you're looking for a quality accurate sub that won't overpower your system and enrage the people you live with, this sub is for you.

Cons: This sub did not come with a subwoofer cable to attach it to the receiver. Luckily I had one.

Overall Review: For the money, this sub produces a fantastically clear, quality sound that compliments my bedroom system nicely.

Pros: The subwoofer does exactly what I expected and more. I purchased a pair of Motion 10's about 3 months ago right after they were replaced by the Motion 20's. Once they were broken in they sounded great for home theater and good for stereo listening. The midrange on the Motion 10's were lacking and the lows as well. So in the hopes of finding some way to get a more complete or uniform sound I purchased the Dynamo 300 which was on sale how wrong can I go. Wow what a pleasant and satisfying surprise the speaker integrates perfectly with the Motion 10's and has tight, solid, bass yet sounds totally natural or as close to a live performance as possible. I purchased all the most affordable equipment from Martin and Logan and can just imagine what a pair of Motifs sound like. Although for my living space in a New York City apartment these are more than enough at a fraction of the cost. Newegg also did a great job of delivering the product emailing me the tracking information and great customer service.

Cons: At this price point none

Overall Review: Highly recommend Newegg in that they have great products, customer service , and timely delivery.

Pros: Good volume and sound quality. I am pleased with the purchase.

Cons: at first I thought the sound volume was disappointing. I After reading more on sub woofer placement and reflected sound waves the problem was solved. I had it 3 feet out of a corner, wrong, 4 foot sound wave average. Once I moved it close to the corner the sound wave and reflected soundwaves synced up better and the volume was great.

Pros: This subwoofer backs up the Martin Logan name with its tight, punchy bass. I was able to play test tones all the down to 25 hz with good output, and strong output at 30 hz and above. While not as punchy and tight as my high end sub woofer, it comes very very close, while only lacking insane levels of volume and the ability to play clean output at 20hz. This sub sounds very musical and not boomy at all. Small for factor and good build quality considering price, make it blend well into room.Great sub even at full retail. Buy it you won't regret it.

Cons: No cons
