[QUOTE="Beginer, post: 2895719, member: 573150"] Hello, yesterday was local dB Drag competition. I tryed my luck and my record was 143.0dB with two Alpine Type R 12" powered by Alpine MRD-M1005 1000W rms @ 2Ohms. I was playing soundtrack. Box is 5 cu.ft, tuned to 40Hz calculated by subwoofertools. What you guys think about this? Can I get more dB with same amp? [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] Maybe this amp is too weak for two type r's ? Maybe if I would tune box to 50Hz and play one freq. I would make more dB's? What is your record with two Type R's? Waiting for your comments [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] Box photo: [IMG]http://img175.imageshack.us/img175/4699/img0896uh6.jpg[/IMG] [/QUOTE]
