Ascent i

Precision and Practicality

Descended from the precision performance characteristics and aesthetic of the Prodigy.

Ascent i expresses MartinLogan's signature language of form and function, maintaining controlled dispersion with outstanding dynamic range, imaging, and detail—all from a rigidly braced, sculpted cabinet that is sleek and beautifully finished. The soundstage, openness, and accuracy exhibited by Ascent i's large, reference-quality electrostatic transducer, high-resolution woofer, and audiophile-grade crossover allow the Ascent i to excel as a stereo or home theater front-channel in any room.

Almost 10 years ago for me and still blown away with the sound of these things. Clean power and cables are a must as any good sound system is only as strong as its weakest link! Martin Logan builds products to last.

Great speakers
I am using Ascent i with Depth subwoofer since 5 years. I can only describe their sound as pure and magical. In the company of Audioresearch front end and amplification they are fantastic speakers for the money. The graceful appearance and musical presentation compliment my house. We are friends forever... Thanks ML for such beautiful product .

I bought my Ascents back in 2005. I have wanted to buy Martin Logan for years and finally made the jump. I was always impressed by the imaging and clarity of the Martin Logan line. Another thing that intrigued me was their presentation as they stand proud and ready to serve. I have had the pleasure of enjoying them more with the component upgrades I have made. These speakers will tell on any flaws or substandard components in your system. For the first time in all my stereo days I am running flat bass and treble. I had recently added the Descent sub. When I thought I already had a superb pair, they were even better with big brother adding in some nice controlled bass. I would recomend the Martin line to anyone looking for an affordable set of speakers that I consider great performance for the money. One more component, the Theater i is in my sights. This system will also eventually serve as my home theater in the years to come. I want to thank Martin Logan for a superb American made product. I will enjoy this for years to come.

Excellent soundstage
I've owned mine about 5 years and also own B&W 803s, both great speakers. Bass is more extended and the image is tighter on the B&W's. However, the Ascent I throws a larger, deeper image with a realism of air and space that creates a more life like experience. Both are great speakers. I recommend the Martin Logan in rooms with balanced room acoustics. The B&W is preferred in rooms that are very live and reflective.
