    When installing subs in a sealed box

    if the sub has a rubber gasket you should cut out the carpet so that the rubber can seal on the wood. if not i would leave the carpet and mount the metal basket directly on it, the carpet will be squeezed and act like a sealing between the hard wood and metal. best thing would be to use...

    I need a new box for my two 12's

    i built a box for two 2005 type S for a friend of mine. 1.4 cu.ft. each worked pretty well. if you want to gain a little on the lower frequencies go for a bit more, like 1.7 cubes. less deep but some more kick in it would be like 1.2 cu.ft. 0.75 cu.ft. must sound a bit boomy and overdamped...

    IB vs. oversized sealed enclosure(Theory)

    you just have to fit the box to your sub. if your sub needs a ported box to sound good, it will not work well IB and the other way around. regarding only subs meant to be mounted in sealed boxes, they will sound most naturally with a Q alignment of 0.7 +-0.2. the TSP of the sub will tell you...

    Deh-p800prs

    in fact CD-ROM drives do not have an error correction especially for audio cds, they only try to correct the bits itself e.g. using the CRC checksum. audio-cd-players have an built in error correction for wav. that is how some copy protected CDs work, they have errors on it an audio-cd-drive...

    Box for 15 DD subs

    be sure to tune the box to 40hz and build it after DD specs. they know what they say. i tried other tunings but 40hz is the way to go, even the lower end output will be better than with a 35hz tuning! 3.5 - 4 cubes each 9515 is OK. DiDan

    nuernberg is a one and a half hours ride from me, a friend of mine takes his studies there i live 60mins southeast of frankfurt. i have the gains all the way down 90% of the time. but sometimes its just time to crank it up and it is good to have some headroom even at 2kW hehe. DiDan

    just an example. but why not? does SQ mean to be under 140 dBs? DiDan

    definitly NOT. volume increase is logarithmic to power increase. you need 10 times the power to get 10 more dBs. double power for 3 more dBs. oh and all this only if the sub can handle all the power without compression. DiDan
