Zu Omen or Tekton Lore

That forward guitar sound is just what I'm talking about,try playing White Rabbit or Soak up the Sun and you will see what I mean.
Not all female vocals will have this problem but recordings like Famous Blue Rain coat will point it out.
A good read here. http://www.audiolofftreport.com/speakersound.html

That upper mid range glare comes right at you.
As for sound treatments the room is carpeted no hard wood floors,acoustic ceiling and 8X16 Sq.ft. sound treatments.

I also tested using my Music hall level 1 mod.CD25.2
To find the same thing.
I do like the idea of Dymamating the inside only where the fiberglass currently is but careful not to over dampen as you could deaden to much.
I came from a first class vinyl rig to loss less file as a way of making room for a new son.
So I know what artifacts can come from both analog and digital but this node lives with in the tweeter i'm pretty sure,having said that not every production run of any component is exactly as the one modeled and graphed and that's why guys like Henry Kloss believed in hand tuning by ear as the final finish,but at $999.00 a pair that's asking a bit much. They are not $7,000 dollar speakers.
Eric, dose a remarkable job in coming very close to the best at a give away price and there is a need for his place in the market.
Being a father now I can't go run out and spend thousands on my hobbies but I can get the musical speaker I have ever heard and spend a little time taming a little peak to make them just how I want them to sound.
I have always hated 99th row performance of todays high end audio (live music dose't sound like that.The Lore sounds like your 5 or 6 tables away from a live band in an intimate night club and that is just what rocks my boat.
When I get them sorted out I'll wright more.

By the way Dynamat and fiberglass serves two different purposes.
The fiber glass absorbs and defuses the rear wave coming off the back of the driver cone and keeps the driver from ringing from directly reflected out of phase sound waves.

The dynamat simply deadens any resonance from the cabinet it's self and reduces cabinet ring or harmonics from the cabinets resonate frequency.

To much dampening can have negative effects on a ported cabinet and I think Eric has found a sweet spot as far as dampening and porting.
The Bass seems layered and tight,not very far off from a sealed cabinet IMO so I really don't think I would mess with that because if the speakers go dead Dynamat is near impossible to compleatly remove.

Wow, I was just here yesterday and there has been a lot posted since.
I agree these are excellent speakers, especially for the money.
Tilt - I put a thin nut on the front spikes so that the spikes could not be screwed in all the way. The back spikes are screwed in all the way, which results in the speakers tilted back slightly. I don't think I need to tilt back a lot because I'm about 8' from the speakers.
Goraman - Is there a link to the spikes you could post?

Dynamat - I posted about what I did with Dynamat Extreme in this thread on 1-10-12. It helps.

Manley Stingray - Goraman, I have a Stingray also, just purchased before Christmas. For those of you with SET amps and Lores or Omens I suggest you at least give a PP amp a whirl, you may like it. For me the SET does some things only SET amps can do, but the Stingray takes my system to another level. I built my SET, my sweat and tears are in there so I want to like it best. But...

Sibilance - I don't experience it with my Lores.

Sibilance you won't find it with every recording.
Play some of the recordings I recommended,also if you remove the driver and look at the caps in your X over,you'll see that they are oblong not round and this means a higher ESR possibly masking/hiding some of the spike.

A capacitor costing under a buck vs. $25.00+ will certainly be more revealing.

I will link the spikes.

I would like to see what you did with the Dynamat.
got pictures up anywhere?

I like my Lores best with my Cary 280 V12, 50 watts of push-pull triode. No glare or sssssibilance at all. For me everything is just right. My Cary 300SEI is also great and the Primaluna Dialogue1 just a tad and a half behind the former two. Even with my Jolida FX10 EL84s there was no sibilance or glare. My office room is 14x16, main room about 16x26. Once broken in these Lores are one of the best bargains in audio. Mega kudos to Eric Alexander.
