This post is directed to those of you who are owners, or have atleast heard, the F12 with the GR driver. Since discovering Rythmik in my search for a sub or two for my 2-channel music-only hi-fi, I have been doing what I imagine all of you did.....read, and think. Then read some more and think it all through again, trying to decide which Rythmik(s) to get. I went from bottom (12" driver and 370W amp) to top (15" and 600W), excluding the FV series. And even to the Rythmik driver and amp in the Salk enclosure. But last night I read a post somewhere from a DIY guy who said something to the effect "I am sold on the GR/Rythmik sound". It was only then that I realized I had not even considered the F12GR. I can guess that a lot of you chose the aluminum driver because your audio system does double duty for music and home theatre, but what's my excuse? Maybe because the aluminum looks hi-tech (the 1501, 1505, and 1510 look SO cool!) while the paper GR seems kinda pedestrian (no offense, Danny!). Or is it because I bought into the notion that sound output is the most important criteria for judging the desirability of a sub, rather than sound quality? It was SQ that attracted me to Rythmik in the first place, but, taking it for granted in a Rythmik sub, I had forgotten about it in my subsequent thinking. My need for a sub is predicated on the fact that my two sets of stereo speakers (one a mini-monitor with a 4 1/2"---ha!---"woofer" driven by a 25/25W stereo Class A SS amp---though they are about to be replaced by a two-way with a 6 1/2, the other the old Quad ESL's driven by a pair of 60w mono Class A OTL tube amps) need not just a subwoofer, but also a woofer (crossed over at 80hz). A woofer that can match their extreme transparency and ability to unravel the densely threaded musical fabric of the music I listen to (Baroque in Classical, with it's counterpoint between harpsichord and strings, and Bluegrass in Pop, with it's close-harmony vocals and acoustic instruments) in my sealed 10(H) X 13 X 19 room. Sure, I listen to AC/DC cranked sometimes, but 95% of the time it's acoustic music at moderate volume. Seeing as how the lowest note in a lot of acoustic music is that of the upright or electric bass playing the open E string at 42hz (though a grand piano goes deeper than that, at what level?), I'm not really in need of extreme output at super-low frequencies, except for the occasional pipe organ recording. So, to those who know about both the GR and aluminum Rythmik 12" drivers, what does each offer in contrast to the other in the reproduction of music? I would love to hear from Brian and Danny!
