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

Yeah, seeing tat x/o would be of interest to me as well. Thigpen shows a diagram of his LFT=8b x/o with values on the ET website, so duplicating it with higher quality parts is not difficult.

bdp24,

Thanks for the info.  Yes, the manual for the 8b has the schematic and values....and lots of measurements and details......incredibly detailed for a manufacturer......thank you Bruce.  So, guys.....get to work.  The stock execution is just average.  Do what Harpo75 has done (tricked out base, bracing, super xover and super jacks and wire) and you will have one of the best speakers in the world....at least for mids and highs.....Add my Music Purifiers and Ground Enhancers for even more detail and musciality.......One 8 inch woofer ain't goin to be that exciting.  I would mount a Lii Audio 15 inch open baffle woofer next to it and bi-amp.....maybe use two 15s......he he.....knock down the walls.

I want this.......Harpo75's system must sound outrageous!

I used the same values as the manual states.  Just much better quality.  If I had the money I could go even further but you can only do what you can afford.  I do have a pair of the Rythmik F12 subs also.  One on each side and back towards the corner of the 8b’s.  They work nicely with the 8b’s.  Not as nice as open baffle subs but very good!

I use a 20 amp balanced AC line conditioner from Equi=Tech.  But I’d like to know more about the various Music Purifiers and Ground Enhancers.  I have test to use any.  I’ve always just over-maxed out the components power supply filtering.  Being a tech person I tend to not buy mysterious black boxes until I know what’s in them and how they work.  Or else you end up spending $500 on a little device that you find out is just a ferrite ring around the AC wire and incased in black plastic so you don’t know what it is.  Yes I’ve seen that done!

Any good forums on these kinds of filters/enhancers?

The Ground Enhancers are a copy of the original Audio Prism Ground Control (no longer available). Please do a search.....you will find rave reviews and more information on those. The Ground Controls were sold for $150 a pair and my better sounding versions were $30 a pair (now a big $40 a pair....actually now FREE with a pair of Music Purifiers). You can see the latest nude version on my website. They are a sonically tuned bunch of damped OFC litz wire. No one really knows why they work as they cannot be measured but the theory is that they act as an electron storage device.....like having a great ground plane. You can find reviews of my Ground Enhancers on line as well.

The Music Purifiers are an rf fliter.....it is a resistor and capacitor in series. They filter the noise on your speaker wire.....that is why they need to be put right on the speakers. The original version was made by Enacom back in the 90s.....then Walker Audio had some expensive ones, then Merlin Audio sold them with his speakers and now Stein Music sells very expensive versions and there are some other clones as well. These things can be measured. But why would filtering the speaker wire abouve 200K make a sonic improvement? Who cares.....it works. Every tiny thing you do makes a difference so I spent a lot of time tuning these and sent 2 or 3 versions to a couple of people to get feedback. The final version uses a modified small Polyprop cap that has its leads removed and the resistor is 5 parallel surface mount resistors that are soldered directly to the body of the cap (also super glued down). The wire on the ground is also soldered directly to the cap body and the hot wire is directly soldered to the 5 resistors.....no leads on any parts. They are suspended in a thick paper tube and the wires are superglued to the tube. The wire is cryoed OFC with Teflon foam insulation. No connectors on the wire......just the ends tinned with Wonder Solder and bent into a U shape to mount on a binding post. In the US they sell for $125 plus $10 shipping and right now I am giving away a set of Ground Enhancers with every pair of Music Purifiers. These are sold with a 30 day money back.....I will pay you $135 if you send them back.....you are only responsible for the shipping to me (maybe $10). BTW.....no customer has ever sent them back.

Both these things are super hand made and you can tell by the pricing that I am making billions of dollars. Maybe I should make a gold leaf version.....or even have rubies and diamonds on them......I could include a hidden ferrite ring too......he he.

Actually, I love that spending so little can result in so much improvement......I love being of service.   May we all be happy.....right now!
