I listen almost exclusively to music and have Magnepan speakers. The room is 14 ft wide by 20 ft long. I have the Maggies about 1/3 into the room. I could probably buy 2 e-subs for the cost of one of the servo based subs available. Does anyone have any experience as to whether there will be a performance difference between e-sub e112 and a servo based sub? It seems that even with their most expensive speakers JL seems to eschew the use of an accelerometer based servo mechanism.
I haven't auditioned the JL E112, but did audition two JL F212 Fathoms. The problem in auditioning any subwoofer at a retail store (even high-end retail) is their room size/configuration and how the sub is setup and integrated. To say I left unimpressed would be an understatement. That was NOT the fault of the Fathoms (these are truly great subs), but was clearly the fault of the setup and cavernous room size (and mains that were clearly under stress).
Obviously, the best way to audition anything is an in-home audition. That way you can see how a sub performs in your room with your equipment. It's too bad that one can't do that with the Genesis G-928 (seems like it might be a great sub).
How do I talk about the following without sounding like an SVS commercial (or fanboy)? I'll do my best
I ended up auditioning the SVS SB13-Ultra in my home, along with another high-quality sub from another I.D. company and was so impressed with the Ultra that I gladly kept it. The Ultra was a snap to integrate with my Maggies. It has a digital panel that quickly helps with the integration process. The panel has many functions, including high- and low-pass filters (I run my Maggies full range and only used the low-pass filter). And yes, my Ultra is used strictly for music. SVS is unique in the I.D. world in that it allows for 45-day in-home trials and free shipping both ways (part of their pricing structure). Don't feel like it's the subwoofer for you? Return it and they will refund your money (again, no shipping charge). Okay, my rah, rah fanboy commercial is over … and I apologize (I hate recommending audio equipment, especially speakers).
Rythmik is another I.D. company that has high quality subs that may interest you (although you will pay the shipping back if you return it … not sure if there are shipping charges to your home, so you should check). Rythmik is very highly regarded here. No matter what I.D. sub you try (there are many to choose from), you get the time needed to understand how a particular sub performs in your environment, and just as importantly, how it integrates with your Maggies.
