Best use of these drivers

[postman]

Hey,
I have 2 of these 8" woofers - http://www.advanceae.com.au/car/prod4.htm

I previously just had one of them in a 40 litre box tuned at 37hz, sounded great for music, really fast and tight sounding.

Since i have 2 now, what would be the best configuration to still get the same sound out of it (good for music, fast, tight etc), yet have a bit more volume.

Theyre rated at 100rms@4ohm each, and i have 350rms on tap.

Largest size box i could use is about 120litres.

Would i dipole work good ?

Any help would be good ! I know planet 10 probably has some good idea on a dual subwoofer !

Thanks !!

was probably going to start building the enclosure tomorow or on friday, so i was hoping to get a few replys before then

No one ever answers my questions

Postman if the single box sounded good then replicate another box...(why reinvent the wheel?)....you could always wire them up in parrallel if your amp is 2 ohm stable

Yeh i was going to just make another sub to go with the one i already have, but if i make another it wont be able to be in as good a position as the single one i have now is

That is the amp i have, it says nothing about being stable @2ohms, is there any safe way to test ? Just running it at 2 ohms and seeing if it works isnt really doable because i dont want to lose it

Im sure someone with more experience than me could give me some help

Postman I followed the link...that amp is not stable enough to run on 2 ohms so your option is to wire them in series and then you can tune the box to a lower frequency (twice the cone area)...you could port it if you want a little more output

try isobaric

thanks for your input joe.

Isnt isobaric just to get 2 woofers into a smaller enclosed or sumthing ? And you need double the power input ?

Wouldnt mind trying to make a dipole or push-push sub or something, but i dont really have any experience in designing an enclosure for them, or whether my drivers would be any good.
