23W4557T002 transmission line sub

[r-carpenter]

Got this driver a couple of years ago on ebay for a bit over a $100. Had it collecting dust on the shelve all this time. Oh well.
So, the reason I'd like to build TL for it now is this. Phil had the same driver in acoustic suspension our last NY DIY and it sounded very impressive. I am thinking, hey why not throw it in the line and see how it does there. How will it compare subjectively?
Phil, you didn't sell yours, I hope, because I'd like you to bring it back over again.
Anyhow, some quick free air measurements. All "near field" with the woofer seating on the flimsy paper box. Didn't have time today to cut a panel for the testing baffle. But the idea is there and it's clear what the driver is capable of.
Next week I'll make a cutout piece for my testing baffle and do it again.
