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.

@ledoux1238: From what my correspondent told me, the Mye stand bolts onto the bottom of the woofer enclosure, the support arms reaching from the back of the base of the stand up to about the middle of the planar panel (similar to the Mye Maggie stands). The Sound Anchor stand is not used at all.

I need to go back through my emails and find the pics of his Mye stands my correspondent sent me. Send me your email address and I will forward them to you (give me a few days ;-).

I spoke with Grand Mye, and he told me he had made only the one pair of LFT-8 stands, those my correspondent ordered. Grant asked me to send the details on bolt hole locations on the bottom of the bass enclosure when I was ready to go ahead with an order. The stand is hollow tubes, which can be filled with sand.

My correspondent told me the Mye stand improves the sound of the LFT-8 in terms of low level resolution and details, overall clarity. Because the LFT-8’s planar panel is attached to the bass enclosure, it doesn’t "sway" as much as do unbraced Maggie panels. But the LFT planar panel is about 3-1/2' long, so it may exhibit a little flexing.

The LFT (Linear Field Transducer) driver has the Mylar diaphragm attached to a very stiff metal frame, to which the fore-and-aft magnets are also attached, that frame bolted onto a solid wood frame. Maggies are constructed with the Mylar glued and stapled directly onto an MDF frame. I don’t remember how the magnets are secured to the MDF.

I've heard the ET's at a few shows, and he's had several chairs in a single file line between the speakers, all perfectly in the sweet spot.  This tells me everything i need to know.... they have a super narrow sweet spot.  They sound amazing there,  and they sound dull everywhere else.  Sorry, but that's not for me.  I need speakers that sound good all around the room, and around the house.

IN that sweet spot, however, they rank amongst the best I've ever heard.

Manley 440 (monoblocks) with Genuine Gold Lion KT77’s set to triode mode 275 watts into the panels.

Manley 440 with 6550’s set to tetrode mode 440 watts into the woofers.

The whole room is a sweet spot. Move around and the musicians remain in position completely stationary. With 1/2 inch Studer A80, it is the sound of live.

People say you cannot reproduce the experience of an orchestra. This system says otherwise. The side and back walls disappear. You are in the Musikverein listening to Der Phil.  

Loud enough for Mayberry’s finest to pay a visit at 4 in the AM.

Richter conducting Bach’s Mass in B Minor: ethereal.

Mehta conducting Holst’s Planets on Mars: invasion.

Weather Report Boogie Woogie Waltz. Boogie ON!

Point of clarification on woofer replacement:

Since I’m using subs, I don’t need the low bass extension of the LFT’s woofer which is obtained by mass loading.

Bruce did a superb job with original Usher, lowering the free air -6dB to 15.3Hz

The Dayton RS225-8 functions more like a upper-bass / low mid driver in my system.
