I had a JL E110. I had it dialed in pretty nicely in another room with other speakers. Moving into this smaller room and changing to the Maggies ... just didn't work. I used a CR-1; bass traps; the subwoofer crawl; and lots of different placement attempts. I thought it was a fine sub and super fun but I couldn't make it consistently work, especially for more demanding music. That's undoubtedly on me--but there comes a time to try something else. The two small RELs aren't in the same league as the JL but they sound much better!
As is obvious, I not especially knowledgable about subwoofers or the physics of sound. Reading around the internet about Maggies and subs is dizzying. (I should add that I've owned Maggies on and off for thirty years.) I think I'm just going to have to take a leap and do some experimenting....
