Tekton Double Impacts

Anybody out there heard these??

I have dedicated audio room 14.5x20.5x9 ft.  Currently have Marantz Reference CD/Intergrated paired to Magnepan 1.7's with REL T-7 subs.  For the vast majority of music I love this system.  The only nit pick is that it is lacking/limited in covering say below 35 hz or so.  For the first time actually buzzed the panel with an organ sacd. Bummer.  Thought of upgrading subs to rythmicks but then I will need to high pass the 1.7's.  Really don't want to deal with that approach.

Enter the Double Impacts.  Many interesting things here.  Would certainly have a different set of strengths here.  Dynamics, claimed bottom octave coverage in one package, suspect a good match to current electronics.

I've read all the threads here so we do not need to rehash that.  Just wondering if others out there have FIRST HAND experience with these or other Tekton speakers

Thanks.

Don't you need to adjust the crossover for all that change in drivers?

No. Not at all. Neodymium mid driver is nice. Most likely what is in the SE. Smoother response and same effeciency. Crossover parts and wire are most important however . Can now use the Gaia II more safely😁

There have been more changes to the crossover with the same drivers (over time) than would ever be needed with these upgraded drivers.

I use the Beta woofers and mid units.  Will be trying the Neodymium Alphalite soon.  Both are drop in replacements no problem at all.

Thanks. So you would wire them in series for 4 ohms then.

Now that's a thought Grannyring, the money saved using the Gaia II's could go towards the cost of the upgrades. Once I get my SE's I'll seriously look into modding my DI's. It would be very interesting comparing the modded DI's to the SE's. My biggest concern is soldering new wire onto the tweeters without damaging them. Any tips on minimizing heat to the tweeter? Would Duelund caps work? I've heard good things about the big Duelunds.

@mac48025 Placing an alligator or crocodile clip on the terminal between the wire and the terminal mount will act like a heatsink and not overheat and possibly desolder the tinsel leads to the diaphragm.

Edit: As a precaution if the alligator clip you use is very high tension and has really sharp teeth, maybe put a layer of aluminum foil between it and the litze wire behind the terminal.  Some alligator clips are meaner than others. No sense damaging the delicate tweeter wire.
