I have 3wayboxes with a 15in sub 1intweets and3in med could i just use theme and not front speakers

I suggest you go over your receiver set-up instructions. See if you need to set the receiver to acknolwedge the addition of the subwoofer. It should be in your receiver set-up steps. Just as a check, hook up one of your other speakers to the subwoofer lead to see if gets audio signal. I'm guessing the issue is your receiver settings.

I dont think that kicker has a recone kit available for L7, after they started building the cone as a one piece structure without a dustcap, making it impossible to align the coil in the gap.
Myself, i have considered the possibility of using the carbon fibre maxxonics recone kits, it may need some tweeking to make it work. but will be quite strong and you could try different coil impedences, aluminum formers etc.
if you dont feel adventurous, than you might be able to send in your sub to kicker for service. i think they just send off a new sub to you, at a discount......

Alright i had a chance to look over things, this is how you are going to hook up the sub. first we'll be connecting the surround sound unit to the sub woofer.
surround sound unit sub woofer
left front: positive (+) <-----to------------->(+) left speaker level in
negative ( - )<- - -to- - - - - - ->( - ) left speaker level in

right front: positive (+) <-----to------------->(+) right speaker level in
negative ( - )<- - -to- - - - - - >( - ) right speaker level in

now that the surround sound unit is connected to the sub woofer you will need to connect the front surround sound speakers to the sub woofer.
sub woofer front surround sound speaker
left speaker level out (+)<-----to--------> (+) left front speaker
left speaker level out( - ) <- - - to- - - - ->( - ) left front speaker

right speaker level out (+)<-----to--------> (+) right front speaker
right speaker level out( - ) <- - - to- - - ->( - ) right front speaker

Alright now that the wires are all over the place and plugged in
turn everything on and see how it sounds. let me know if everything is working as it should. if you need help with anything else or if something does not seem right please feel free to contact me via e-mail or phone

It sounds like you may have the speaker in the box wired out of phase. It is important that subs be wired in phase. Try switching one of the wire sets from one sub (put the + on - and vice versa.) Only do this for one of the speakers. If the connections are inside the box, you will have to get in there to do the change.

It sounds like you're doing everything right. Did you define the sub to the Onkyo (Subwoofer = Yes, page 22)?

Let's prove the sub works. Set its volume about half-way, cutoff= 170Hz. Temporarily connect an RCA cable from its Line Input to one of the Tape Out connectors on the Onkyo and play some FM through it. If it's alive you'll hear the low end of the music.

Don't buy into the hype that there are different pedigrees of RCA (or speaker) cables that will make an audible difference. Save your money.

you have enough air space for 1 L715 or 2 L7 12s the 12s will move more air and hold more power than 1 L7 15 inch sub

it really depends on ur choice but if it were me id get the biggest mono block amp i could to run the sub. and id run a 2 to 4 channel amp to power the rest.that way u get ur bass on it own supply and the voices on there own supply.if u want more detailed help let me know [email protected]

slightly reduce the base-boost knob at the backside of sub.....or change current audio theme to soft rock in audio proporties

i wanna full version themes for my desktops
