Today I made a Drastic change in my set up, was running 2 12" Type R's in a prefabed sealed Box, then tried them in a ported Box, over all I like the sealed box sound better for my metal and rock music it frikn was very tight and still murdered the lows on certin freq's , switched to a ported box and didnt like the sound, it just didnt acomodate my style of music, sure they was hitin low @ certin freq's alot more but over all I wasnt happy, , so I did a drastic change, I ditched the 2 Type R's and got 3 -12" CVR's Custom Sealed Box will be finished in a few hrs , builders almost finished , Im hopeing that 3 sealed 12' cvr's are gona realy pound the hell outa my rig and walk all over what I was useing, cant wait to heare em, anyone else drop 3 12 cvrs ? how do they sound sealed , anyways ill post some pics on my entire setup today
