Hi looking to upgrade to either of these subs. The SRX is the slightly dearer one and harder to come by ATM, but are they roughly the same performance wise? I cant compare them side by side so I'm hopeful some of the very learned folk on here may have an educated opinion?
I haven’t used the XP118, but based on the spec sheet, the XP118 is probably a touch louder (though these numbers can be fudged a bit). Out of the two, I’d easily take the SRX, it has a -3dB point at 35Hz and a -10 at 29Hz. It can put out a reasonable 31-32Hz. The XP118 is 42Hz-150Hz ± 3dB, -10dB @ 38Hz.
The SRX is great performing sub for the price, and for a bit more than it can get the 828SP which is an incredible value (if you start with the 818s you can get the 828s down the road for bigger shows). I’m sure the XP118 is a good performer too based on my experience with Martin gear. If you don’t need it to get as deep get the XP
