    Martin Logan - Great 10” Subwoffet

    Adds excellent bass to my Magnapan 2.1 diaphragm speakers. I use it in a medium size and the 10” speaker provides plenty of punch. I was thinking I might need a 12” but this is great. I’ve always been a Martin Logan fan and this is the reason.

    Best subwoofer I have ever owned. Frequency goes down to around mid 20hz range and it made big difference from my old polk sub. Great price for the performance. Salesman went out of his way to hook it up and demo. Wasn’t on display. Great customer service at Magnolia HT. Chattanooga Tn.

    Outstanding Sub. Much better than the Jamo 260 (which died) it replaced. Clear and resonant bass from the lowest lows through the frequency band. The adjustment makes fine tuning easy. Thinking about getting a 2nd one to make my theatre system a 7:2 Atmos.

    This is an outstanding subwoofer for the price ponit. I was told at Best Buy that MartinLogan makes really quality subwoofers at a range of price points. It really delivers on the bass.

    Beyond Surprised with the bass from this Sub! I was running with a high end 12" subwoofer and it went out so this is its replacement and does just as well.

    Excellent subwoofer so far. I have it in a 12 by 12 bedroom. It sounds great. It replaced an older Martin Logan 8” that lasted 10 years or more but started making crackling noises.

    Great quality product !!! Everything I hoped it would be. From the moment I hooked it up what a difference from the last subwoofer I had. Sound quality and power was just what I was looking for. Would definitely recommend this product to others if your looking for a new subwoofer for your theater room.

    Blew after 45 days of easy use

    I have a full 7.2.4 theater in my basement with 2x 18" subwoofers and 3,000 watt amp. This set up gets pushed. This Martin Logan subwoofer is paired with Kef R3 in a 2.1 living room set up that is mostly used for my 4 year old to watch bluey and is never pushed. The subwoofer is capped at 40% on its amplifier and volume is always at casual listening volumes. This sounded fantastic while it worked; however, it only lasted 45 days. The subwoofer no longer works. Checked the fuse - still working. Attached to another receiver/different outlet/different cables - nothing. I was originally debating between this and the REL. Should have purchased REL.
