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

Harpo75,

So glad you are tweaking everything in your system......Here are a couple more things I have experienced:

1. 12 gauge Jantzen wax paper coils sounded WAY better than 14 gauge Jantzens on my Neo 10 planar midrange driver.

2. Going into the inside of the foil and coming out the outside is noticeably superior sounding......so, outside to driver or to ground (if used as a shunt).

3. Bypassing an inductor with a very small value cap results in more transparency. My friend with the modded Apogees put one of my modded .15 Wima caps across his big copper foil coils to ground on the tweeter circuit.....more clarity. He also has a Wima cap across his Mundorf copper foil iron inductor on the woofer panel....However, he never removed it to see what difference it is making. Would be good to get some feedback from you using it on a series coil on your midrange. I no longer have the Neo 10.....so cannot try it.

For the woofer, I would use the largest gauge coil I could find......you could also use the Mundorf iron core copper foils:

Would love it if you posted a detailed pic of the xover with values.....so those with the speaker could tweak easier.  The ET panels are custom, so there is no lose for Bruce by sharing the xover.  In fact, he could learn what other people have found work good and incorporate those parts in his future speakers.....I want a 90 db single panel version with more woofs on the bottom.....done with all state of the art parts, base and bracing.....me drooling.

Have fun,

Ric

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?
