Tempest-X 15" subwoofer high excursion -Portland, OR (1 Viewer)


Oct 13, 2014
Real Name
I have a like new Tempest-X. I bought it new and it has less than 10 hours of use. I built the speaker box you see in the photos for it and ran it with a Dayton Audio HPSA1000 1000W rack mount amplifier also less than 10 hours. I set it up for my home theater and watched likely one or two movies with it and the whole home theater got disassembled when my kids moved back in with me. It has set for years unused not even wired. I have been using the speaker box as a table/stand for video game consoles, so it has some wear on the paint.
Local pickup...

Local pickup preferred, I am in the Portland, Oregon area. I am more specifically in east Vancouver, Wa.
Let me know if you have any questions or would like to see it.
Don't have pics of the amp right now as it is in a box somewhere buried in the garage.
