Steve Guttenberg finally reviews the Eminent Technology LFT-8b loudspeaker.


 

Over the past few years I and a number of other owners of the Eminent Technology LFT-8b have on this site extolled the virtues of this under-acknowledged loudspeaker. I myself have encouraged those interested in Magnepans to try and hear the LFT-8 before buying. That is not easy, as ET has only five U.S.A. dealers.

I am a long-time fan of Maggies, having bought my first pair (Tympani T-I) in 1973, my last (Tympani T-IVa) a few years ago. But the Tympani’s need a LOT of room (each 3-panel speaker is slightly over 4’ wide!), which I currently don’t have. So I gave a listen to the MG 1.7i, and didn’t much care for it. As I recounted in a thread here awhile back, I found the 1.7 to sound rather "wispy", lacking in body and tonal density (thank you Art Dudley ;-).

Brooks Berdan was (RIP) a longtime ET dealer, installing a lot the company’s linear-tracking air-bearing arm on Oracle, VPI, and SOTA tables. After Brooks’ passing his wife Sheila took over management of the shop, continuing on as an ET dealer. I knew Brooks was a fan of the LFT-8, and he had very high standards in loudspeakers (his main lines were Vandersteen, Wilson, and Quad). The shop had a used pair of LFT-8’s, so I gave them a listen. They sounded good enough to me to warrant investigate further, so I had Sheila order me a pair, along with the optional (though nearly mandatory) Sound Anchor bases.

I wouldn’t waste your time if I didn’t consider the ET LFT-8b to be just as I have on numerous occasions (too many times for some here) described it: the current best value in all of hi-fi. Hyperbole? Well, you no longer have to take it from just me and the other owners here: Steve Guttenberg finally got around to getting in for review a pair (the LFT-8 has been in production for 33 years!), and here is what he has to say about it. After watching the video, you can read other reviews (in a number of UK mags, and in TAS by Robert E. Greene) on the ET website.

I saw the Steve Guttenburg review and thought of those here - particularly that had mentioned the Eminent Tech’s before. Very impressed. I’m with @aniwolfe in considering the LFT16a’s for my 10x14 room. Just been corresponding with Bruce about them. Really nice guy, very responsive as he just got right beck with me today. He explained that they have new woofers, of which I was curious  as the Stereophile Atkinson review of them back in 2008 (he had complained about a low mid bump in his measurements). 
 

 

There is a second reason why planars seem more efficient. They drop in level at 3 dB as you double listening difference and regular speakers drop at 6 dB when doubling. The standard efficiency is measured at the same distance for both planar and point sources but we rarely listen at 3 meters, usually more than 6 meters so there the planar plays louder for the same input. 

Excellent point @dynamiclinearity, I had forgotten that fact. That difference in drop off in output level with distance is one reason why monopole subs are not ideal mates for use with dipole loudspeakers (also the opinion of Magnepan’s Wendell Diller): if you balance the two at 1 meter, the balance will be different at greater listening distances.

I’m sure that was one reason Bruce Thigpen decided to design a dipole woofer system, now offered in the LFT-8c. If you already have a dipole sub such as the Rythmik Audio/GR Research OB Sub, you can use it in place of the woofer in the LFT-8b. You merely don’t connect speaker cables to the LFT-8’s woofer binding posts (or use the provided jumpers), using the controls on the dipole sub to create the required 180Hz low-pass filter. Of course very few subs will play up to 180Hz; the Rythmik/GRR OB plays up to 300Hz!

I watched SG today. First time in a while. I think they were at Axpona?

$3k or so. I just received a pair of LRS+ I had ordered last December.

They are quite a disappointment considering all the rave I had heard.

When I placed the order Magnepan offered a 60 day trial period.

Now I see no mention of any on their site.

Anyone know anymore on this?

 

Thanks,

At Axpona they were playing an unreleased ET speaker that sounded very good. Unfortunately, I don't remember the details.
