2 x JTR RS1 Subwoofers; amp, 18” driver setup identical to RTJ 18Sub Dual

1 x Speaker Power SP- 6400 (Upgraded 240v version, however still works with 120v)

They were originally purchased Oct 2023 (JTR - Warranty through Oct 2028 / Speaker Power amp warranty through Oct 2026). I’m the second owner of these. I just upgraded to the JTR RS2 subs after Christmas 2025, so these will go to a new home.

This amp configuration delivers 3200w per channel and so can deliver +50% additional headroom if you have opportunity to use a 240v outlet.

This amp configuration gives easy access to the amp controls for simple integration / modification without trying to get behind the amp/sub box. It also keeps the heat and noise outside sub box for temperature and noise floor performance.

JTR stopped this configuration which is a massive shame. It would cost $12500 + delivery to get the closest set up from RTJ however the RTJ configuration has a smaller cabinet and so will not dig as deep. This makes this configuration of the sealed RS1 the best you cant get any more.

The plate Amps on the standard RS1 only deliver 2400w. I’m sure if you are looking at this ad you know about the massive long lead times at JTR currently.

I welcome locals in NW Houston to come audition these - still in my system along with the newer RS2 pair. And I can freight ship - I have the pallet from the RS2.
I will also consider some trades for McIntosh amps (particularly monos), Bowers diamond speakers.

These are also listed on US Audio Mart...
Have a look at this ad for photos for now until I get some uploaded to ASR. Thanks!

Mid-March bump. I have double boxes for each sub, box for amp, and a pallet for all to go on.
