Hey guys, so i'm starting to piece together a decent and which would be my first sound quality system. I have a small list of subs that i'm interested in and am hoping would work well in an infinite baffle setup. But first off, let me list the other components that will be going into it... HU- Pioneer Dex-P99RS, Tweets- ScanSpeak Illuminator D3004/6020, Midrange- Hybrid Audio L4, Midbass- Peerless 830667.. MB Quart DSC2150, MB Q4.150; The sub amp will be determine after i chose the subs but something like [email protected] or 4ohm.. The amps are pretty budget friendly amps for now, but plan to move on to more high end Arc Audio or DLS amps in the future. Okay on to the subs. I want to do 3 12's behind my rear seat. Mainly deciding between the Dayton Audio HO12($150), Dayton Titanic MKIII($160), TC Sounds Epic($190), and FI IB3($190). My budget for the subs is $600. I don't know how loud this will be, but i'm guessing it'll be plenty of output for me and hopefully when properly setup sound very nice. I just want to see if anyone has tried any of the above in IB and how the results were. If anyone has any advice, i'd really appreciate it. I hate how i have the hardest time trying to choose the drivers that will play the smallest frequency range, i just want to pick the right one. Lol Thanks!
