Tekton Double Impacts

Corelli, the transducer centers are a 1.5ft from the side walls and 2.5ft from the rear wall. I didn't move them durning testing because I'm not going to move them when I listen. So that would be pointless. They are positioned in front of corner Bass traps that extend from just off the floor, almost to the ceiling. The rear wall is also treated with flat panels below the HT screen and stop about 4ft off the floor with the screen above that level. I also have bass traps in the rear room corners and additional absorption panels at most reflection points on the side walls. I actually had more absorption panels at one point, but with experimentation discovered imaging and depth was better with some of them removed. Evolvist heard the DIs in my room, but later posted he hadn’t hear the DIs in a treated room. All I can assume is he wasn’t impressed with my sound absorption efforts and didn’t feel it was a good sample. Hey, I do what I can. It sounds pretty good to me and looks good on a graph. Imaging is great with the correction on or off and not a real noticeable difference in the low end. Mostly it seems to improve the image depth placement and adds a bit of detail in the mids and highs. The big thing is, it made a huge difference when I tested it with my B&W 804s. It was like night/day on them and brought them much closer to the sound of the DIs. It was pretty impressive. I guess it makes sense that the better the speaker, the less correction it needs. And the worse the speaker, the more of a change you’ll notice.

How much better are the Eminence Beta 10a woofers and Eminence Beta 6a 6.5 inch midrange drivers compared to the stock drivers? I guess I asking if replacing them as a first step is worthwhile at all or doing you need all the other mods to hear improvement?

What are the part numbers/name of the stock drivers anyway?

I guess it makes sense that the better the speaker, the less correction it needs. And the worse the speaker, the more of a change you’ll notice.

Not sure I agree with that. I think it depends on the design of the speaker. I had Dipoles and they actually were not designed to need a lot of room correction. My Electrons required much more room correction. Was the dipole speaker better than the Tekton? Not to me.

Room modes are a property of the room and not of the speaker. That said, dipoles like my Quad electrostats excite fewer room modes.

I want to caution folks who want to plow ahead and do an upgrade. Please note I said my crossover may be different than your DI crossover based on others who have looked at their parts and values. You must take apart your set and see what is in there. The builder is indeed changing things with time. Dont just order the values I did as yours may be different.  I had an additional inductor that another owner did not have on the array. His resistor and cap values were also different.  Since we don’t know the coil values you may not be able to order the extra one you need to match my board. 

Understand what you have. Diagram it, plan, and plan some more.  I think the earliest sets were changed to what I have.  Did Eric change it more since August/Sept? Perhaps, I do not know.
