slugdub Posted March 18, 2009 Report Posted March 18, 2009 I read a review of the old ZX750.1 and people complaining they couldn't get the extra few notes out of their amp that they wanted. Is this really a factor one should consider in an amp?
raytard Posted March 19, 2009 Report Posted March 19, 2009 in short no especially for a sub amp all it has to do really is be capable of playing like 20hz-90hz people didnt realize the kicker has a subsonic filter on it most likely, its there to save your subs, and cuts power under a certain frequency so you dont damage/unload the subs (25 hz, well below most people's tuning, some SQ freaks with high end woofers and sealed boxes would notice, everyone else likes it) Build: http://www.stevemeadedesigns.com/board/ind...hl=avalon+build monster/rockford/kicker/stinger cables, pioneer source, jbl highs/amps, kinetik/shuriken batts, iraggi alt, dei security, dc subs(atleast for now) Team DC
slugdub Posted March 19, 2009 Author Report Posted March 19, 2009 Well the amp I'm getting (I'm happy to have finally found one) does not mention any frequency response, its N/A? http://www.crutchfield.com/p_108R611A/Infi...tures_and_specs And then I read all this jargon about frequency, enclosures, max RMS and whatnot that has me worried (like no subsonic filter means less max watts and shorter speaker life?) Recommended Sealed Box Volume: * Compact (minimum enclosure volume): 1 cu/ft; the woofer can handle up to 400 watts RMS (200 watts per voice coil) * SQ (maximum enclosure volume): 4.6 cu/ft; the woofer can handle up to 300 watts RMS (150 watts per voice coil) Recommended Vented Box Volume: * Compact: 1.75 cu/ft; 2.5" x 12.5" port opening; 20" port depth; the woofer can handle up to 300 watts RMS (150 watts per voice coil) * SPL/Deep Bass: 2.25 cu/ft; 3" x 12.5" port opening; 20.5" port depth; the woofer can handle up to 300 watts RMS (150 watts per voice coil) Note: The power handling specifications listed with the vented enclosure recommendations apply only when a 25Hz, 24dB/octave subsonic filter (sold separately) is used with this woofer. If a subsonic filter is not used, power handling may decrease, excessive port noise can occur, and the life of the woofer may be shortened. http://www.crutchfield.com/p_2067C12VR2/Ki...b=detailed_info
Team_DC-Derrick Posted March 19, 2009 Report Posted March 19, 2009 LP Freq: Rotary control to set the cutoff frequency of the Low Pass Filter thats what your amp has..... The DC Integra 3 18s to 6 15 build log Team_DC-Derrick's Youtube Team DC Audio where theres a will theres a wall....... I just realized Steve has reach Voldemort status, over on JP's site he is the one who will not be named....."We dont speak his name over here, fearing it will destroy us" LOL not even in hush tones
slugdub Posted March 19, 2009 Author Report Posted March 19, 2009 I figured as much. So '25Hz, 24dB/octave subsonic filter' is a fancy way of saying, adjust the damn low pass above 25hz?
