Tekton Design Double Impact Loudspeakers

For your consideration is a like new pair of Tekton Design Double Impact Loudspeakers. I am the original owner and have had them since 9/2017. They have approximately 300 hours on them, so I think they are just now breaking in (Eric says 100 hours-no way, they are way better now than at that point). I've been going back and forth between these and a pair of Magnepan 1.7s, and I just think I am a Mag guy. These are in great condition, and come with original boxes and packing. They include the $300 upgrade package described below. These cost me $3300 in September of 2017. Also, the spikes are included, but not shown in pictures. I kept swapping the two sets of speakers out (Mags and DI) and spikes made that difficult, so they aren't in the pix. You will find them in the styrofoam at the top end of one of the speaker boxes. Below I've listed the specs taken from the Tekton website. Please go online to read all the glowing reviews of these speakers.
They have been packed exactly the way Tekton Design does it, using all that came with them. That being said, buyer will take responsibility for any damage that may occur in shipping. I prefer a local sale, but will ship at buyers expense. Shipping at $200 to the lower 48, free local pickup (cash sale then). Paypal, credit card add 3%. Thanks for looking.
