Designing a closed cabinet for the Eminence Beta 12CX

[Grymer]

Don't take too long thinking.

Next year and your move to university are rapidly approaching!

Haha. "Think about it" as in - I'll order the parts Monday-Tuesday next week, and I'd think about it till then, but actually. I'm settled on the Beta-12CX. Look at the nice pictures I've taken of my Sketchup file

i know the dizzy thing . . .

Sorry to hear that. It's simply variations in blood pressure that affect me.

Didn't see your pics till after I posted.

Nice design work - now go translate it into reality!

is it ok to drop battery voltage a "few" volts with series.paralleled diodes? (I'd like to run a little amp off a 20v drill battery)

Heads up, I think your setup will be just fine. I've got 12cx in ~30 litre cabinets and two Lab12 sealed 30litre subs, sure jab2 and jab3 as amps (2x40W+100W) with 19V psu so not that much amp power available. Had a party a week ago and it was just enough volume for us 30-40year olds Windows were rattling in the living room and conversation was possible in other rooms.

Amps using the TPA3116D2 can do 4.5-26v. The voltage will drop. In my case it will go from 50,4v to 43,2v. I have no idea how a drill-battery works. Not even sure if there is a built-in BMS (Battery Management System). <- Basically monitors the battery and cuts connection if battery is low-voltage.

But an amp using the TPA3116D2 will definiately do a 20V battery

Remember using a fuse so you don't fry the system haha

Haha. There's a turning point in life. The age where you'd like sound levels that give you tinnitus, and the age where you like sound levels that don't

And sweeeet setup! And yea - I won't be cranking it to 300w whilst indoor haha

BLACK: Tham12 - 12FH500
GREY: 30L sealed - LAB12

Corner-placed. Both get a total of 1w.

I don't doubt those LAB12's sounded brilliant! Would like to hear that setup.


Using ADAU1701 I'll add psycho-acoustics to achieve sound below 47hz
