Line drivers and inverting a RF T-1 10?

Anyone here use line drivers (RCA booster) for SPL comps? I was told that their not needed by a local audio store. However a couple of guys I go to comps with, use them. Also what effect will inverting a T-1 10 have on SPL comps? Is it better normally installed with a decent sized port?

You should do some experimenting with a line driver if winning an SPL comp is your goal.  It's all about experimentation.  And inverting a subwoofer will not do anything for you.Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

I have only noticed gains in using a Line driver when useing 2 or more amps.   For 2 or less, no diffrence at all. For one of our 6 amp setups it did help Inverting the sub has cause a few vehicles I know of to lose db vs gaining anthing besides having a big mag structure hanging out of the box2009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR

Cool, well I will be running a 1200watt Rockford amp (401s I think) and 1 T-1 sub. I am not looking to set any recorsd but I would like to do better than a 134.8 with 4 P1s.

what style comps are you running?   what orgnazation?    I could help you get much louder with the current setup you have, but need to know the Org to follow rules2009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR

Street 3 ( I think) in USAC

I also run a outlaw class once a month. We tried flipping down the visors, moving the seat foward, it helped maybe .2-3 DB. Its in a 98 S-10 EXT cab if that helps. My setup is as follows: 1 RFX-9220 deck 4 P1s wired @ 4 ohms 1200W rockford (401S) 2 i farad caps big 3 upgrade with 4ga wire optoma battery My system runs at 14.75 volts @ 2000rpm.

Hey Jeff what do you think?

is the 134.8 the street beat run or outlaw>? Is the box sealed or ported?      We did some testing with a rockford T-2 12 on a kicker kx1200.1 and it was in the low 140 range...about 144 if I remember right, and that was for outlaw...but it was A streetable setup so tuned very very low for comp use. 2009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR
