Floor Loudspeaker Reviews

My first exposure to Manger Audio loudspeakers, which are based on the "bending-wave" technology invented years ago by the company, was to the Manger p2, their passive flagship speaker, at the 2019 AXPONA. I heard it again a month or so later at High End Munich. I was impressed both times, especially by its transient and spatial performance.

We wrote a long, rather unkind report on the HQD, pointing out that, if that was typical of the way it was supposed to sound (And why not, after Mr. Levinson had installed and tweaked it?), then it had to be the most expensive bomb ever to be made available for civilian use. Mr. Levinson responded with a phone call during which he:

1) Told us we had not heard it at its best, but refused to address himself to our specific criticisms;

2) Claimed that many practicing professional musicians felt the HQD to be "extremely realistic";

3) Informed us that, since he sold very few HQD systems and would soon be discontinuing them anyway because Quad had ceased making those speakers, the "sensible" thing to do would be to kill the report; and

4) Mentioned, just in passing of course, that he was currently writing a feature article for Time on the subject of "underground" audio magazines.

Marten is a small Swedish loudspeaker manufacturer with great aspirations, some of which the company has largely met. Leif Mårten Olofsson founded Marten and designs the speakers, while brother Jörgen Olofsson runs the business as CEO—a division of creative and administrative labors similar to the working relationship between David and Norman Chesky, the founders of Chesky Records and HDtracks.

As I prepared this review of the Marten Mingus Septet Statement Edition loudspeaker ($199,000/pair), I asked the Marten people to tell me something about the company and its values.

2020 may not have been a year to celebrate, but there were some housebound highlights. For example, after I had finished with the measurements to accompany Michael Fremer's review of the Marten Oscar Duo in the November 2020 issue, I set up these Swedish two-way standmounts in my own listening room. Yes, the measured performance was excellent, but I was not expecting how much I would enjoy the sound of the Oscar Duos.

The quest for a full-range electrostatic loudspeaker has occupied many engineers' minds for many years. The problems are manifold: large physical size (which can lead to room placement problems and poor dispersion), the difficulty of achieving high sound pressure levels, the need for a potentially sound-degrading step-up transformer, and the unsuitability for production-line manufacture. Even so, the potential rewards are so great that one can understand why loudspeaker designers keep on attempting the apparently impossible. Epoch-making models do appear at infrequent intervals, keeping the flame burning since the appearance of the original Quad in 1955: Acoustat, Sound Lab, and Beveridge in the US, Stax in Japan, Audiostatic in Holland, Quad, of course, in England, and now MartinLogan.

I prefer and have owned electrostatic speakers for most of my audiophile life. Depending on your point of view, this makes me either the most qualified or the least appropriate writer to review MartinLogan's new electrostatic loudspeaker, the Masterpiece Renaissance ESL 15A.

Oh, I've flirted with dynamic speakers. I've owned and loved—and ultimately, when I was an audio retailer, sold—models from Revel, Thiel, Vandersteen, and many others, while my long-term choice has been electrostats. And while I've spent plenty of time with electrostatic speakers from Acoustat and Quad, I've ended up owning MartinLogans: Sequels, Quests, ReQuests, and, currently, Prodigys.
