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
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
