John or anyone..still thinking about subs!! Does a band pass need a crossover?? I know a lot of you reccon that I should stick with a sealed cabinet. I remember John you mentioned a Pioneer Band pass box you loved.. I have all the Specs from JL Audio in America. The speakers are 2 x JL8W6'S.

the problem with a band pass box is the size.

nom

and they boom.
Which I wouldn't have thought is what you are after, the same note (very loud) all the time???

My Pioneer box is very loud for the amount of power it gets, but is cheap tack compared with what you want from the sounds of your install. It is a dual port bandpass which seems to prevent it being a one note wonder and broadens the response a bit. A lot of people shy away as the dimensions are very exacting and the calculations a headache for a dual port. It is 31 litres and weight about 8 kg. It claims 129dB in car off 100WRMS and it sounds like it too, and all off an 8" driver. There is a "Deathbox" in the US which does similar and you can buy the plans. But the audiophile cognoscenti say they are crap but loud.

I have taken the box out the attic and scanned in and retouched the freq response off the side of the box so you can see.

Cheers for e-mail. Think I will stay with a sealed cabinet. I just want to eliminate other ideas!!! Last thing I want to do is to start wearing Puffa jackets and fitting blue LED's to W/S washers!!

Got some great plans for my door builds...

If you want to throw cash at your install I would always stick with sealed and go for big power. If anything I am regressing on the ICE front - considering taking out the sub and putting some 6x9 in the back shelf low passed off the 2 channel sub amp to lighten things. I have turned into a boost monster since I was into all this ICE stuff. I'll see. I think the sub is secure enough for tracking the car.

John, How you doing?

I tried the running full range 6x9's with 150,120,100,80hz low pass route and got very poor results. The speakers were JBL.
I did consider buying 6x9 bass speakers/subs but didn't bother in the end.
Just thought i'd tell ya.

Thanks, any other ideas then?

I have some 6x9 in the back of our 406 and they really do the bass thing quite well even compared with some subs, but they have no filter.

Maybe I should just keep the sub- I have saved weight on the exhaust and when I go over 300bhp it won't matter much.

I'm sorry I don't have a link for this,but Kicker makes a dedicated 6x9 sub.Or at least they did.I've heard a few good reports on them.

Just a thought...
