Zu Omen or Tekton Lore

Thanks for sharing, Rocky! I've been interested in playing with the crossover based on Goraman's experiments, so it's great to hear Eric has some recommendations along those lines. I need to call him. Can you share the details of the caps and resistors recommended?

Goraman, could you compare this approach to yours? It sounds like this adds a zobel network, while it sounded like you mainly just substituted different caps in the existing crossover design. Did you try a zobel approach as well?

Here is the info.
"If you think it is the 10" transducer bothering you try connecting a 4uF capacitor and an 8 Ohm 10 Watt resistor wired in series with each other - then place this across the positive and negative connections (a parallel connection in relation to the 10" driver)."

The parts I used were a 8.2Ω 10 watt high power Metal Oxide non-inductive resistor and a 3.9uF Jantzen Audio CrossCap. (Closest I could get at the time of ordering)

It seem to get better and better after a couple of hours of the mods.
My ears were maybe udjusting to them.
It has been a great improvement in my system. Even at normal listening levels which does not seem to make much sense from what I have read.

Saw this graph on doing a search.

For me it has made all the difference and I am thoroughly enjoying them now.

The good thing with this mod is it was easy to do. Unscrew the driver. lift out and then solder parts on. Put back in.
Getting to the crossover looks to be a little bit tricky.
I too might look at that later like Goraman mentioned.
Right now they are sounding great.

I haven't found the need for a Zobel network,even at 18 to 20 watts per channel the impedance curve seems pretty stable to me.
Possibly due to the non inductance resisters,internal cabling and upgrade caps presenting a better over all presentation.

They do seem to have a peek between 1khz. and 2khz. as dose most drivers in the extended to to full range variety but it doesn't seem to change with increasing volume.
Or maybe Rocky 500 notices it more in his particular room as he rocks up the volume knob.Hard to say but it dose make for awesome guitar riffs.The Lores are not ruler flat near the upper ranges,I knew this from the first audition,the ZU Essence is far flatter than the Lores but they have a huge peek in the very top end from 15K on up with bass remaining tight but not as prominent as the Lores.
The Lores are a fantastic speaker but they don't graph like the Bonneville salt flats.

Hey guys. Good to hear from everybody. In light of my interest in recreating a live event, I am thinking trying out a Crown XLS-1000 class D pro switching amp with my Tekton Pendragons. I am curious to see if it will give me the dynamics I am looking for. Dynamics are very good with 12 watt Xindak, so I can only imagine w/ a pro amp. Any thoughts?
