Elemental SP

[DiamondAudioFan 10+ year member]

i'm wondering if one Elemental SP 15" sub in a 1.5-2ft.^3 enclosure would outperform in SPL 2 Diamond Audio 12" subs. (M5's).

I would polyfill the box to make it seem a bit bigger than it really is.

thanks for any help you can provide.

Polyfill the box? Everytime I ask if I should do that people say "No it doesnt help tha much" How much exactly does it help? Because my L5 15" kicker in a 4.2 + port + displacement, I was gonna stuff it with tons of polyfill and try to make it think it was like in a 5 - 6 foot box //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

You are looking for a 50% gain, polyfill will not help you with that...

You can get up to 25% more on average.. use about 16ozs per cubic foot is the standard...

so say 4 cubic feet so use about 64 oz of polyfill and stuff it through the port? lol

poly fill just makes the box seem bigger by slowing the sound wave a bit inside the box //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

so therefore polyfill can help a whole bunch... because box size is crucial.

The port needs to be unobstructed. The best way to do so is wire mesh...either chicken wire, or just screen like you would use for a screen door.

so just stuff it through the port into the main box area, and see how that works? //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
