Need T/S parameters for a RD sonance 15

[Bassin Buick]

i winged a box last time when i built one for this sub. RD is absolutley no help at all every since that douche guy sold the company. I can't find full T/S parameters anywhere and they won't even give box recommendations for it online. I called them awhile back when i built the first box and they literally told me they didnt know what size box it would be at home in. I went 3.5 @ 30 but i would like to try something different this time because it had a tendency to get kinda sloppy at high volume in that box.. So anybody with this knowledge please come forward and help a cracka out.

Some people say 6 cubes for a pair which would put you at 3 cubes after port and displacement tuned at 32Hz.

well i'm 3.5 @ 30 before woofer displacement now. and 40 sq in of port. Think i will get a drastic improvement or should i just leave my box alone? It's a stout box , so no mechanical need to rebuild one. I just was contemplating trying something different.

Ive read the Sonance subs require smaller enclosures. My DC was the opposite. 4.5 cubes before displacement and port.

maybe i should go smaller then? my buddy has a real nice box he is selling but it's tuned to high IMO. its 2.6@36hz birch with a killer kerf job. But like i said , that is just way too high for my tastes.

If anybody knows the parameters for an alpha 12 let me know cuz Iv called RD and talked to

The co owner and they don't have a straight answer for me

nobody at that company knows there head from a hole in the ground. i forget the dudes name but word is he shredded all the important paper work and files and **** when he sold the company. may be a rumor but thats what i heard from someone there about a year ago right after the 3750.1 fiasco.

well i didn't get any specs , but a guy on the phone was pretty helpful. He told me if i was running 500 or less to it i could go 4 cubes and 40-50 SQ in of port , and if i go 3-3.5 and 30-40sqin it could easily handle 1KW daily. So i think i may just build one more box. 3 cubes @ 32hz and see how i like it. I can always go back to the larger , lower box. But i plan on around the 1KW mark for power so he told me to stay between 3-3.5 cubes and i will be good.

He actually knew there was a SQ version and a SPL version and he knew the difference between the two. So i'm assuming they got some competent staff working there now.
