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.

I’m using Herbie’s Giant Threaded Stud Gliders. Depending on what thread size your outriggers can take, they may be a relatively inexpensive option. $280 for a set of 8, less if you are using a three point outrigger.

Herbie also has a very generous trial and return policy.

They are listed about 2/3rds of the way down the page in this link:

I’m using an unconventional setup with two sets of Herbie’s Giant Gliders and an isolation shelf in between, with excellent results.

I have the Gaia IIs and they made a slight difference but not enough to justify the spend (vs my Herbie's setup).

They will be going back (for the reasons that Mac mentions: too much weight for the IIs to perform well) and I will have to either go with the Gaia I or take a chance with stability/tip over concerns and go forward with a Star Sound Tech platform (which has been my first choice for a long time now, but I’ve been holding off on account of my son’s safety).
I was using Stillpoints Ultra SS under my Crescendo's with good results but they leaned out the mid-range too much and since then I've found the Audio Points to be "Outstanding" and is what I'm using with very good results...

Very good discussion on this worthwhile topic of vibration/resonance management. There are no shortage of products available that's for sure.  I happen to use the Star Sound Apprentice platforms under all of my components and speakers. They are very effective and unquestionably improve the sound quality.  Most especially with speakers. It's a well thought out and engineered product.

Thanks for this tip as I built a set for my Lyngdorf 2170 with great results for under $50. I am building another for my server/player and BPT & CPT balanced conditioners. 
I made my own "outriggers" out of 5/16"th X 1 -1/2"W X 15" long steel, with Sound City 2.10" spikes with good results.
