SPL heavy-hitters and recognized box designers, come hither please

[teamsubgopoof]

he showed me a video of his install the other night...and his subs aren't moving at all...at first I thought he was playing just real close to tuning, but when he showed me his port...its a vertical port around 200 sq inches firing back...i understood.

That back woofer is unloading like CRAZY and basically cancelling that other woofer out.

Playing some jeezy and they aren't moving at ALL.

I told him to go all the way across the bottom of the box to help the woofers load the port a little better..(thats part of the reason aeroports work so well //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif)

He is talking about using 2 mt 18s for now...and 4 18s later...on a maxximus.

I told him to do around 12 cubes, 120/140 sq inches of port around 15'' deep...will tune him a little under 40 hz and should go insane...you can go a little smaller on the port and the same depth and tune it lower if it doesn't give you the output you want

flexing doesn't always increase OUTPUT persay...but it could increase SPL //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Weirdddd....i never even heard that before....im not one to say its not true, cuz so many things that i dont know its not even funny

haha. there he is. i like the look of that box also. what 12s are those?

Double layer or add bracing to that enclosure without re tuning...i bet you'll lose a few tenths..

and even re tuning you probobly won't be back where you should be.

We tried alot of things in our crx and the bravada...even a steel and concrete enclosure...a single layer box was the loudest

Reread my posts......he added a brace down the center of it and gained 2db from that....//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

then something was flexing SUPER bad then.

I'm not talking about bracing a single layer particle board 15 cube box and gaining.

I'm talking about gaining with a well built spl box that has minimal flexing already //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

forgot where i was for a second there //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

Yehh i hear ya....this was a pretty well built box from a Teammate of urs on Maxxsonics...Matt Sibley?.....its only 2.4ish cu total....

no seats except front in also

Put those subs side by side width wise, with the slot port/aeroports underneath the subs, I believe thats what justin told you to do and I'd agree with that.

I can only go off me and my next door neighbors results were.....and he gained 2 WHOLE dbs from putting in a brace along the sub mount baffle and screwing it to the sides as well

This box here.....maybe in bigger boxes that works dont know....never heard of boxes flexxing to increase output

Like I said man, not every trick works for every person. I added a double baffle and threaded rod to my single 10" box and gained jack squat. But other things gained me .5. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

yes i've known Matt for years...he knows what he's doing //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Things inside the box. Luckily the added bracing didn't hurt my score.

i told him that //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

lol...

now this all makes sence Justin.

 

[teamsubgopoof]

ya know...looking at that 4 10 box...

i don't think the brace is what gained..

i think its the way it loaded the woofers, its basically a divider there...also if he didn't already i'd make it go down as far as possible before hitting an aeroport

again spl is all about manipulation of air, and in that enclosure if you don't have a piece between the woofers they are going to fight each other....the divider was more for fighting cancellation not really a brace //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Im surprised you havne't tried to talk him into 200 10s.
