ASC Tube Traps (pair) 11 inch

ASC Tube Traps in black. 11 inch pair. Rated 7 for age only.
Excellent condition. No rips, blemishes, etc. Tubes are 37 inches tall.
I will ship these if the distance is fairly close.
Example: Shipping UPS to Dallas, Texas from Lafayette, Louisiana is $105 total for the pair, including $200 insurance on each tube.
(In the first picture: 11 inch tube traps are the bottom tubes in each corner.)
$350 price is for the 11 inch pair.
Using these in the corners, behind the speakers, is like a major component upgrade.
Following the ASC directions... Start with a pair of 9" or 11" tube traps in the corners, behind the speakers, with the reflective side aimed at the listener.
Then add a second 9" or 11" tube trap on top of the existing tube trap in the corner.
Then add a set of tube traps (11' or 16") behind the listener in the other two corners.
Finally, add a half round or round trap at the first refection point on the side walls, midway between the front wall that the speakers are in front of and the listener, to the left and right of the listener.
Also... these are $350 for the PAIR. Another seller, in the last 30 days, was selling their tube traps for $300 each.
Thanks for looking.
