Would you recommend Super Sub X?
Stereo configuration (from manual)? Or should I look for a receiver w/LFE connector?
"Left and Right Line-Level (RCA) Inputs– For use in a stereo configuration using the Left/Right preamp outputs of
your receiver, processor or integrated amplifier. Use RCA-to-RCA cables to connect the subwoofer and position
the Input Switch in the LEFT/RIGHT IN (Up) position, as shown. In this configuration the subwoofers’s crossover
control is now active, allowing a setting that matches the roll of of your main speakers"

I am currently just using a vintage stereo receiver and old sub with R/L speaker cables to sub and another pair of R/L speaker cables to BRX from same R/L output of amp.

I have Triton 1.r w/ref center and Triton 3+ surrounds in the HT.

Hi Vectra, First, the SuperSub X would do a great job when teamed up to the BRX bookshelf speakers. The SuperSub X is clean, powerful, and quite musical. I would highly recommend using this subwoofer with the BRX bookshelf speakers. Next, there's really no need to use a processor with an LFE output, or subwoofer output. Connecting the left and right pre-amp outputs of your system to the left and right low level inputs on the SuperSub X would work very well. In this stereo configuration, the low pass crossover on the subwoofer is fully operational - which would allow you to dial in the crossover frequency to properly blend with the BRXs. I suspect you'll find a crossover frequency in the range of 50hz - 80hz would work well in this application. (As long as your main receiver/amplifier has left and right pre-amp outputs, you're in good shape.) Happy Listening!

This message seems to answer the questions I have but can someone clarify, if I use the SuperSub X with my BRX's and my Technics amp which has a pre-amp output, how do I control or lower the amount of bass that is passed on to my BRX's? The technics amp doesn't have any bass, mid or treble knobs, only a volume control for all three.

Hi Tdisme, When using a SuperSub X with your Technics amplifier, you would not be able to reduce the amount of bass sent to your BRXs. The Technics amplifier - as well as the SuperSub X subwoofer do not have high pass filters (that would reduce the amount of bass sent to the BRXs). I do, however, believe this setup (your Technics amplifier, the BRXs, and a SuperSub X) would still sound quite natural and musical. The BRXs have a limited bass output below 50hz on their own, whereas, the SuperSub X would fill in these lower frequencies below 50hz (and blend with the BRXs quite well). Happy Listening!
