splx1 Posted April 8, 2013 Report Posted April 8, 2013 hi,everyone. i have a DD M4A amp,& i want to buy a subwoofer alot of spl. cadence zw1520k thats 6kilo RMS or groundzero GZPW15SPL.... i modeled it in WINISD and it showed unblievable spl numbers and i compare it with GZPW15 SPL of groundzero that has 10kw spl power. in that software in same conditions the cadence was alittle bit better than the groundzero more DB(about 2 DB.) the things in cadence sub thats take my attention to it was big BL 36.093 & big SD(989.8 cm) for a 15 inch woofer and form of its coil. i think it has better coil than groundzero. but there was no video about it on the internet.this subwoofer is same as spaudio 15x in one look there is no diffrence between them.. i dont know buy wich one to use. GZPW15 SPL OR Cadence ZW1520K??? what do you think???????? (srry about mistakes in sentences cuz im not good in eng.)
