Eminent Technology LFT-8c Robert Greene review


A friend of mine forwarded this review to me a couple days ago.  I hadn't seen it as it's just a week old at this point. 

Why would I be interested? I have a pair of LFT-8b speakers that I picked up about 7 months ago.  Wonderful speakers. I always wanted to try a set of panels and, as luck would have it, last summer I found a used pair of 8b's just a short drive from my home..I made the jump.  As it turns out, this was one of the best moves I've made in my 50+ year audio hobby. 

In the last few months, I was considering picking up the 8b to 8c upgrade components, but put it off as I had a number of other projects going on.  Well..the projects got completed and I started a few more projects, though this time around the 8c upgrade is one of them.  I ordered the 8c upgrade yesterday and I'm really looking forward to the adventure once it arrives. 

One thing I've noticed when reading discussions of the LFT-8(no a, b, c)  here on A-gon, is the discussion wanders over the now 36 year history of the LFT-8.  Issues identified in this or that review from 10-20-25 years ago are brought up as if they reflect what the LFT-8 is today.  LFT-8's had a great sound 30 years ago, with a few flaws, as any 30 year old speaker would, and it sounds better today. Nothing surprising there. Most companies cut ties with models as they age and come out with something new, whether they are really new or repackaged parts..that varies.. 

What's my point?  I just find it interesting that Bruce Thigpen (Eminent Technology) came out with the LFT-8 in about 1990 and has been continually improving the model 8 year after year, decade in and decade out, staying in business with no advertising, though with a few shows here and there. There are very few current speakers(let alone businesses) alive today that have a 30+ year history under largely the same name. (Though the Vandy 2 series comes to mind)  Pretty unique in this industry.  It's also pretty unique that a decades old pair of LFT-8 speakers can be upgraded to the current model at a very modest cost. And the upgrade is easily done by any owner. 

So..the latest review:

Robert Greene goes into considerable depth in his review, which is specific to the 8c version, though he's done an 8b review in the past. I'm glad it came out as it pushed me over the edge in ordering the 8c upgrade.  I'm not getting any younger..time to give the 8c a spin. 

One last note, I've read in a number of older and current reviews that the LFT-8 speaker placement is..finicky.  I haven't found that to be the case at all.  In the last 7 months I've experimented extensively with placement and they respond well to various setups. My current setup is about 115 inches between the panels (on center) and maybe 30 degrees toe-ed  in from facing directly forward.  Each speaker is 45 inches off the front wall(on center) and 38 inches from the side walls.  I have a great soundstage and and equally great imaging.  My tweeter panels are on the inside. 

 

(...and no..I have no affiliation with ET..just a customer owning a used pair of the 2017 model 8b)

With the LFT-8 midrange driver on the inside, you are getting less driver output loss due to beaming (even at midrange frequencies, far below 10kHz) compared with that driver on the outside (where the listening position is further off axis).

@bdp24 After a further week of listening with the midrange panels on the inside edges of the speakers, I concur with your analysis. There must have been some loss of output in the midrange / upper midrange frequencies with the midrange panels on the outside edges. The frequency response seems more balanced in the midrange. This also allows the placement of instruments in the soundstage to be spread more ‘realistically’ rather than in amphitheater style. The depth of the soundstage is also enhanced. 
 

I would say that for a narrow room like mine, 11 ft, and speakers’ edges at 8” from side wall, turning the midrange panels to the inside makes for better room interaction. I have not done any measurements, purely through listening. 

@ledoux1238  (& bdp24)

Thanks for the follow-up.  I look forward to trying the mid panel on the inside edge.  

Well it appears that come this Saturday I will be the new owner of a gently used pair of LFT-8cs. Wish me luck.

 

Awesome @ozzy62! Did the current owner mention why he was selling them? If I had a room big enough for a pair of huge SoundLab ESL's---and the money to buy them, and an amp to drive them---I can see myself doing that. But as is I'm quite content with the LFT-8b/Rythmik-GR Research OB/Dipole Sub combo. If I had a room big enough for the SoundLabs I would also set up my pair of Magneplanar Tympani T-IVa's, which are currently sitting in their shipping cartons.

 

The guy moved and his room got smaller and the WAF kicked in. No dedicated room, so they were set up in the living room. Recipe for disaster.

If anyone who owns these is reading this, can you tell me a little more about the bass response? I know they don't dig deep, but can they do justice to metal and hard rock at reasonably loud levels? The reviews and feedback I have read don't mention this very much.
