Just so you'll know, the Rythmik Servo Feedback plate amp is available in two different XLR versions, one of which (XLR2) allows master-slave hook-up, operation, and adjustment of multiple subs. The feedback system also deals with the resonance of the MDF enclosure, as well the thermal artifacts endemic to ALL drivers. Those effects are the result of the electrical characteristics of all woofers changing as their voice-coils heat up and cool down in normal operation. That's just the tip of the Rythmik iceberg. As I said, very sophisticated! The Rythmik website goes into great detail explain Brian Dings design.
DUAL SUBS IN THE $10,000-$15,000 RANGE
I just sold my pair of JL F212's after hearing the Gotham(big mistake!). I'm about to drop $15G's for a pair of used(store demo's) Gotham's that have being upgraded from v1 to v2. Now since I'm about to spend big mula on bass, why not consider others awesome subs that may even be better than the Gotham's(if possible). I want my subs to do both music(primary) & bombastic movies(secondary) with LOW distortion. Please comments on the list below or add others I am missing. I listing them in my preference. Thank you!

new kid on the block..... SLP- 120DB at 20HZ with less than 1% distortion! http://magico.net/product/ssub.php http://magico.net/Marketing/Press_Releases/S-SUB_PR.pdf same retail price as the Gotham 213. |
ptheo, thank you for sharing the magico s-sub info. I wonder how much bass one needs in a typical HT or 2-ch setup? How big is your listening room? I just installed a f212v2 last month in my HT room (15"Dx30"W). Just one of the 212's is freaking amazing, I can only imagine two of 212's or a pair of Gotham's in my setup. |
lallitk- My room is 27'D-17'W. My complaint is not the output of my F212's(mostly 1/3 up & never past half way), but the way the drivers were working so hard once I cranked it up for movies(Mission Impossible- Rogue Nation beginning airplane screen) which causes distortion to rise which causes the MDF box resonate more which colors the sound/output. In my demo with the Gotham's, I got none of that. Just hard hitting clean/low distortion bass with no box resonating/muddying the sound. Sold! |
