Tekton Double Impacts

I've had both with my D.I.'s being I believe the most current version.

I would describe the 2 models performance as very similar with the D.I.s having a deeper bass response, although I doubt most would deem the Electrons to be  lacking in that department. The D.I.'s also IMO are slightly smoother responding with a shade more depth. However, those features could just be the most recent modification that have been added to the design.

I sure liked the weight of the Electrons a lot better.

Anyone in Southern California have Electrons or Double Impacts? Lunch and beers are on me if I can get a quick demo of these monster speakers. Drop me a line at skystudiosmusic@gmail.com - cheers!

I'm curious on getting different opinions on room treatments that DI/SE owners have found effective.  My current dedicated room is about 21x14.5x9.  When I designed this room I tried to use ratios that were favorable.  It has double thickness drywall, vinyl plank flooring over concrete, with carpet over that in the rear half of the room.  The front wall has MDF rectangular columns to help break up and diffract sound waves.  The rear wall has DIY 3.5" rockwool absorbers over most of that wall.

The room to my ear is on the bright side with a bit of slap echo.  As I do not find the DI's bright, I don't mind a room on the "live" side.  But I suspect some side wall treatment is in order.

The other issue is bass response.  I received my Hsu sealed subs.  They came with a nice test disc.  This was an eye opener.  While I knew the DI's had tight bass in my room, testing really reinforced my impression.  There was a marked null at 40-50hz, and then better output to 30hz (the tuning frequency of the port), with little below that.  I have pretty much an equilateral triangle with speakers/chair.  Moving this all out further into the room placed my listening spot closer the rear wall, and with the subs in the front corners, I did clearly improve the null. (40hz still a bit down in response)  Response now in the room has good extension to 20hz and at least by ear fairly smooth up to 80-100hz  where there is a bit of a peak.

So in an effort to improve the acoustics of my room I've been reading all kinds of posts/articles--- and advice is all over the place.  Some say clearly to treat first reflection points, others say this will close down the sound stage (which I really would not desire).  ? use diffusion  instead on side walls a combination of diffraction/absorption. Bass  traps to smooth the 80hz peak (and how the heck do bass traps "know" I only want to dampen at 80hz, not 40hz??).  I am limited as only one corner is available for traps (subs in front two, door in the other).

I know in the end I'll have to probably just try things.  Just hoping to avoid costly mistakes.  Thanks guys.

Lyngdorf Room Correction ,and your done :)

I'm wondering if your "slap ehco" is a result of the other half of your vinyl plank flooring not being carpeted. Possibly trying throw rugs on the other half? Just an idea.
