REL Subwoofer: Speakon or RCA?

Using Speakon is the only good thing about REL. If you were to use RCA, there’s a lot of other subs that perform much better.

great post, you know this as a total fact and you have heard all of the possible combinations of Rel and ancillary gear.
Nice to know your opinion...even though you conveniently forgot to add....imho.
IMHO.

Not an opinion, based on pure performance, an equally priced sub from say Rythmik, SVS, PSA, JTR, etc. will easily outperform it. REL doesn’t offer deeper extension, louder output, better microdynamics, more musicality, etc. In today’s age, you can get better for your money, they may sound good, but not as good as it’s modern competitors.

REL SUB-BASS SYSTEMS are not designed for use in applications where the main speakers are externally crossed-over to eliminate lower frequencies from the mains, to substitute for poor bass performance of main speakers, nor to induce terrified responses to explosions while viewing the latest mindless action movie. In those applications, mzkmxcv is correct that REGULAR SUBWOOFERS provide better results than REL.

REL SUB-BASS SYSTEMS are designed to provide room pressurization of frequencies around and below 20hz and to slightly augment bass performance of full-range loudspeakers in that region. The net effect of a properly implemented REL is audibly improved soundstage and a solid bass foundation for music with near perfect integration with most full-range loudspeakers when used with the hi-level connections from the amplifier’s speaker outputs. If that is the intended application, nothing else compares to the RELs IME.

Over the years I've heard systems with various subs from old Velodynes to Vandersteens and others not having a V in their names, and RELs certainly hold their own compared to anything out there, including my 92 lb monster studio sub that's actually flat to 19hz...RELs are great designs, period. My 2 RELs cost 200 bucks each used and in mint condition by the way (Q150e I bought first maybe 5 or 6 years ago, and Q108 MK II I found maybe 2 years ago), perform perfectly and are musically transparent in the sense that when properly set up they simply disappear.
