Burp box...

The box i posted is an 8" aero on a box that is 3.7cu. Thats a good amount of port area, and it does fine

This might be frowned upon... but i dont pay attention to any of that. I never use winisd. I dont feel its practical for spl, where literally nothing makes sense... i build, test, rebuild, retest etc.

I just KNEW you were going to say that... LOL!... well this is attempt #1 then... I'll finish it up and post how it went... no matter the results... I hope it'll gain with the tuning change...

Tuning low to mid 40s with alot of port should put you around 149 legal depending on power

That's what... a little over 50 in2 but an aero... you can utilize a slightly smaller port area if you use those... correct?

Yes, aero is like 9-12^2

Was testing earlier... 30 sec music average

So just go for it and set my SSF at 35-40 since I don't know what power I have... it seems to be pretty high...

Yes, use ssf. Idk how rugged the spiders are on those evls.

I dont use ssf, but i dont really listen to music when the burp box is in, and if i do, i avoid **** like decaf.

I've got a daily setup and that box is my baby... it's VERY close to a box for 2 12" X's and eventually that's the plan... this will be only to burp not demo... I'll be careful to avoid the LOWS for once... I'm surprised at the durability of these EVL's as I usually play 35 and under constantly but I do know what you mean... they are NOT really meant to throw 4"...LOL!... I wish...

Just stay above 40hz and you can still play stuff to test it out

Webbie 6 12s 45hz and 55hz

Jeezy Prime Minister 47hz

Ciara Goodies 51hz

Jay z Hello Brooklyn 2.0 49hz

Beamer benz or bentley 53hz

Project Pat Rinky Dink (rumble) 51-54hz

^^^^^ this ^^^^ ... what does that mean.. I'm assuming that tells you how to figure port area with an aero?

 

[kr15 5,000+ posts]

Oh no i just meant to say that aeros are effective at 9-12sq in per cube. Where as slots are usually 12-16

That's exactly what I meant... high power levels need closer to 12 in2 per cube...correct?.. but you still will need sufficient port area... Thanks... I've not been giving too much "advice" lately but reading posts instead and learning... I don't want to step on it any more than the next guy... all your help has been invaluable... I think I just might do okay next Wednesday... we'll see...

Depends a little on driver and amount of throw they have...as long as im not an extreme range on port area, i focus more on frequency and metering style. Those are related to port area also

Jeez... LOL!.. it IS build and test... repeat... but those guidelines are generally correct I hope... it'll save me some sweat... I AM in Phoenix...
