Zu Omen or Tekton Lore

One of the problems was due to my positioning,I tipped them back,Eric said that would spike the tweeter by as much as 3 db. After leveling them it helped alot.
The other issue is with a bright pair of caps soon to be swapped. I am not blaming anyone for the sibilance and I'm surprised no one else has made a capacitor upgrade and chased these issues already. My advise would be to use very neutral caps Clarity cap,Ansar,Daton,Solon as any peak in the upper mids creates a problem.

Wow! since leveling them and letting them run in some more from sun up to sun down over the weekend and for 2 hours I ran the volume at 12:00! somewhere around 10 watts!
Suddenly the high end went flat so I removed the resistor I added to the tweeter to drop the spike by 2 db. and still no glare,seems the new caps smoothed out and the sibilance just vanished as fast as it came.They got another 38 hours just since last week end of break in time.So now I have more caps coming,they can just sit,no more cap rolling!
All I am going to do now is go in and remove the Xovers and clean everything up,replace the resistors with Mills non inductance and there done!
In the end it will all be worth the trouble but one piece of advice is be very careful to select neutral capacitors and give them some time to smooth out. Mine took close to 90 hours.
Funny thing is when I first put them in no sibilance but they went through a 50 hour or so stage where you couldn't stand them,I seriously hope this is it and they are done with no more surprises! This is the most radical burn in I have ever encountered,although I did have a similar issue with clarity cap SA a few years back as they lost the top end for a while and suddenly it emerged after a couple weeks of use. So I guess I shouldn't be to shocked.

Im following your posts quite closely Goraman.
I too find the Lore's a bit like you have explained.
Please keep us updated with your progress.
I have sent off an email to Eric(before I read your posts) asking if he had any tips/mods I could perform to tame the Lores a bit.
I am finding them a little forward/agressive at times. Not sure if that is the terms for it.
I find if I turn them up a bit, I seem to always be looking to adjust the volume all the time.
Love the bass and midrange but something about them has me swapping them out for another set of speakers I have here.
Its long term listening sessions that they don't quite do well with me.

Guys - since we are on the subject of cables, do yourselves justice and hit ZMAN up. His cables are simply THE BEST I have heard with the Tektons. This is not an advertisement for him - it is down right silly to not try as he is one of our brothers here, and because his cables are NOT expensive and I am telling you that are amazing. Cryo and burning treatment makes some really interesting changes for the better. He just came out with a new SIGNATURE interconnect that is as natural as I have heard - no glare or etch whatsoever. You may think you don't have this issue, until you try a set of these and then its wake up time. At least that's what i experienced.

Rocky,
If your Lores are Bone stock and positioned level with your floor,your probably experiencing something different.
The Lores are not a laid back music from the lobby or parking lot presentation,they make me feel as if I am 6 to 8 cocktail tables away from a live Blues band in an intimate night club.
They are a forward sounding speaker.End of story.
But not forward in an uncomfortable way with my amp ect...
If the top end is what bothers you, there is a mod to tame it.And you can tailor it to your ears.
If your speakers have less than 200 hours I'd recommend giving them more time to break in.And Eric is a wealth of knowledge so keep him informed as you go.
