Re: Driver below recommended Vas, but all other requirements are perfect
I'd do it.. Your Qts, Fs and Xmax are there, and if it fails to impress you, you have a reason to save up for a LAB15

I didn't notice it before but the 100-300L Vas recommendation is for fifteen inch drivers. Twelves have smaller Vas than fifteens, so you should have been comparing against recommended twelves. The Dayton RSS 315-4 Vas is 84L.

TLAH. I already have SLA's but they look like pro-audio cabinets with stands. Center will be a 6 driver curved array and I'll get to the surrounds last (actually the mains last since I hate all the wiring).Keryn O'Shea wrote: ↑Sat Oct 14, 2023 9:42 pm I'd do it..

Re: Driver below recommended Vas, but all other requirements are perfect
I feel dumb. Your plans have a lot the same info on the first few pages so I gloss over most of it to find the pertinent info. like driver specs. I didn't follow the rules and read the plans completely at least 3 times. Literally the next sentence after T/S specs. I'll make sure to give myself a few lashings after each panel is cut.Bill Fitzmaurice wrote: ↑Sun Oct 15, 2023 7:51 am I didn't notice it before but the 100-300L Vas recommendation is for fifteen inch drivers.

Don't feel dumb Jimbo. The way the plans read, I would have assumed the stated specs were universal to either size driver too. There should be clear T/S spec recommendations for each driver size in the plans.jimbo7 wrote: ↑Sun Oct 15, 2023 11:02 amI feel dumb.
