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.

Eminent Technology LFT-8b speakers with modified bracing of the Sound Anchor stands.  Yes I went ahead an did it with extremely positive results.  

After reading about the Mye stands for the LFT-8b speakers I took a look at the Mye website.  He does some very nice bracing on the Magnepan’s.  The description of adding bracing sounded like it would be an excellent idea and addition to the Sound Anchor stands.  I didn’t want to spend another $800 or $900 on all new stands. Then the idea to just get my trusty mug welder out and add some bracing.  The idea is nice for the C-clamp but I felt adding the bracing right to the front metal plates would be much more stable and provide better damping.  Also I didn’t  like the look.  I would need to lengthen the four front hex screws in order to bolt the braces to it.  

After cycling through a few ideas I came up with an idea I liked that would be rock stable and also be easy.  I bought four 3/4” weld steel square tubes and a short piece of 3/4” flat weld steel.  After welding (I’m just adequate at it), grinding and painting I filled the tubes with about 2/3 lead shot and 1/3 fine sand.  Mostly because it’s all the lead shot I had and it’s gotten very expensive!

I used #10 -24 bolts and washers to attach the braces to the rear of the Sound Anchor legs which I painted.  I had to be very careful at tapping the holes there as the leg metal of the Sound Anchor is not super thick.  Figured if it stripped I can put nuts inside and put a little spot weld to hold them in place inside the legs but all is good.  Ordered 1-1/4” long black button hex head screws to attach the braces to the panels.  These replaced the four existing ones. 

Definitely added some extra weight. About 2-3 pounds.  Worked out great.  Could feel right off the panels were way more rigid.  They would flex a bit before when you moved the panel back and forth with your hands.  Now they’re rock solid!

So now to the sound improvements.  Well it was huge!   I know what you’re thinking.  He built something and made a change so he has to hear something.  Well right off I was amazed.  Seriously!  The entire sound is so much more solid and drums are tighter.  The image just has this solidity to it.  That was the word I kept thinking.  Much more stable image and better sound stage.  The highs even actually sound cleaner.  Now that surprised me actually and wasn’t expecting that.  I’ve always felt the tweeter could be improved on the LFT-8b’s and this made a great leap forward in just sounding smoother.  Cymbals come through much cleaner than before.  Everything just appears in space better. 

I remember when I added the Sound Anchor stands and thought Wow!   Nice improvement.  Adding the braces was more like a double Wow!  Really.  One of the biggest improvements I’ve made in a long time.  And I’ve made a lot!  I had upgraded the crossover parts a while back and that was spectacular.  Maybe that’s part of the reason why I noticed so much of an improvement with the bracing. 

It’s really improved my listening enjoyment to a whole new level.  I highly recommend upgrading your stands to something with a brace like this.  It’s literally  hard to stop listening!  

I’ll try to post some pictures here soon.
