It was delivered the next day (WOW) and is a bit smaller than the Grotto, but had the familiar look and feel of an American made product from Martin Logan. One problem was the port extension had come lose inside and needed to be reattached. Rather than send it back, I just took the amp out and fixed it myself. Setup was pretty easy with my Onkyo receiver, I set the crossover frequency at 100 and started playing with placement. After a couple of days of break in, playing with the placement and reducing the crossover in my receiver to 90, it started giving me the results I was looking for. It has enough power to fill my small room with very good bass and works well on movies and music. Don't let the 70 Watt rating fool you, this thing tumps.
The sound is accurate and tight. The extension is very good, it goes much lower than I expected and without being boomy like so many woofers. Some notes: Setup the system to crossover to take over where your main speakers leave off, as low as you can. My speakers can go down to 50 Hz but don't do a good job at anything below 80 Hz so I set the crossover at 90 Hz. At 100 Hz it was way to boomy. I then used the receiver crossover to remove anything below 90 Hz going to my main speakers and that made a huge improvement.Read more ›
I read through all the reviews and got a good feel for what to expect. A sub that, at first, would sound a bit harsh, but that would "settle" as it moved past the break-in period.
I received it on the very same day predicted by the Amazon ordering system, and raced home to set it up, leaving work early and breaking several speed limits in the process. The packaging was solid, and the sub arrived in good condition.
After reading the manual, I proceeded to set it up in the front corner of my entertainment room. The reviews were right, it DOES sound a bit harsh and out-of-place at first. The bass hits were heavy and sort of distorted, but this was to be expected after reading through the manual as well as all of the prior customer reviews. I watched a couple of movies with good sound-tracks "The Dark Knight", "300", and "Braveheart" to see how it would integrate with my system. Although the sound did have that harsh edge, it still produced a much better overall theater presence than my sub-less system did the day before. I decided to break it in the quick way, and set up some streaming music to play continuously during the day while I was at work. After a few days of 8+ hours of music playing through it at a moderate volume, the edges started to smooth out and the sound became much more musical and transparent.
People say the best speaker is the one you forget is there, and that's exactly what this sub is.Read more ›
Have been using the ML 300 with a Pioneer 1223 (not quite elite, but similar tech), and the depth is more impressive than I would imagine from a woofer this size. Having it positioned up near the front sound field gives the whole theater experience an immersive sound, that is where most theaters including IMAX place their subs. My speaker setup has also changed except the center channel; Bose 161s for FR & FL, Klipsch Quintets for SR SL, subwoofer turned up half-way also sounds superb on a padded and carpeted floor. The room size is no larger than 20X20'. Cheers
Just a brief review for those who might be considering this purchase. (This is not edited for perfection). But I am a graduate student with lots of practice!!! I really hope this review helps you decide what is truly best for you based on several factors. This review is hardly exhaustive, rather it is enthusiastic and summative.
It is my first ML product, and there are quite a few positive reviews online besides Amazon, so do yourself a favor and research it thoroughly.
I say this because it most likely is limited to specific size rooms and home theater system set ups. For example, I have Harman Kardon AVR 1700 in a smaller sized living room, with Klipsch Quintet front LR speakers, a Definitive Technology Mythos 3 CNTR, and Bose loudspeakers for SRL.
Not a huge system, but definitely fully equipped with clarity and excellent sounds in music and movies and games on the PS3.
What does the subwoofer do well? I transitioned from a Bose bass-module set up to this one. The Bose are full across the board. The Dynamo truly goes beyond full, more into the realm of deep and distinct.Read more ›
