Have you tried the highpass in your E112? You just loop it in/out between the pre and amp. It will add some hiss for sure as JL’s electronics are very questionable but it should be night and day better. I would highpass at 60hz. If you like the sound of that the CR-1 would clean up the hiss as it is made much better than the junk in the E112 (I own two, no hate just calling it how it is). The E112 is a great driver backed by garbage electronics.
Subwoofers: add a JL Audio or switch to 2 Rythmic subs?
Am considering adding another subwoofer to my main rig. System features Magico A5 speakers and one JL Audio E112 subwoofer in a dedicated 29' by 16' by 10' listening room.
The speakers run full range and the sub runs off the second line output of my Audio Research Reference 5SE preamp. The sub is crossed over at about 40 hz via its own internal low pass crossover.
As is the system produces plenty of bass, which reaches to about 25 hz. The sub is not detectable sonically but it's output in the low bass is a little down compared to mid and upper bass.
I've been contemplating adding another sub to smooth the bass response a little and also add a little output at very low frequencies. I was also thinking about adding bass traps in the front corners behind the speakers, again to aid in low frequency smoothness (room currently untreated).
I'm intrigued and have been reading about the Rythmic subs (12SE). They seem to be highly regarded by users on this site. Additionally, they are available as a pair new for the same cost as one new JL E112.
Not sure if it's worth the trouble to even go down this road and looking for advice.
Thanks!
