[QUOTE="ds0110, post: 8091340, member: 607866"] Ive wanted a soundsplintert rlp since soundsplinter went out of business. I never thought id see a dual 2ohm in good condition for sale and now there are two for sale in the classifieds. However, I have a never used flatlyne sitting next to me that is supposed to be the best sq sub available if the hype is true... The box im going to use for this install holds one sub. Im trying to compare them to see if its worth the trouble of trading out/ selling what I have to get the best outcome. I will be using 1.16cuft sealed box. 750watts. The goal being "daily sq".
