Small correction: "Acoustic-air" should be "The cone".

nobody answered my Q, about the smaller baffle cutout offering any amount of compression. is it worth attempting to cut out the baffle to suit?

the other alternative, is to leave it as is, with the 12inch driver.

please help

Hi klampykixx,

Posts #1592/1585: "i currently have a 12inch driver in it. so it has a 12inch hole. i want to use a 15inch driver in it but dont think i can get a jigsaw in there to make it 15inch. so its either leave it as 12inch, or make a standoff ring 15inch diameter"

You should be OK with an adaptor ring: make an adaptor/standoff ring to fit the 15" with enough room to prevent the cone/surround from hitting the wood.

If you want to know what it does at low levels: enter the driver data and horn data into Hornresp, measure/calculate the throat chamber details, and enter them into Hornresp as Vtc/Atc/Ap1/Lpt.

If you have trouble working with Hornresp go here: Simple Tapped Horn Tutorial using Hornresp .

Regards,

And done (for now!).

Can't wait for the first full power field test on the weekend, then I'll finish em in texture paint if I'm happy with everything.

One SS15 and two (sort of...) HS12

Damn the Kappa Prof 15LF2 is heavy. Going to have to look at paying the 100 bucks extra for the neodymium 3015LF. I think it's worth it for the weight savings and the extra xmax.

just had em pumping for a brief period at what i think was about 70% of what theyre capable of. must say, im quite pleased with them. they sound solid thats for sure.

i must admit tho first impression tells me theyre not as deep as the old china subs i had. but they should get deeper as they run in. theyre pretty stiff.

anyone recommend run in tracks?

It's just noisy movie music, lots of percussive noise in the bass.
