I'm planning a new sub for my HT and I just want to get some input on it before I start construction. Here are the details:
Adire Audio DPL12 12" Driver
2.5 ft^3 Sealed Enclosure
Parts Express 250W@4ohm Amp
It'll be used for both two channel music and 5.1 movies. WinISD is showing me an F3 = 30Hz, F6 = 22.5Hz, and an F10 = 17.25Hz. Will this give respectable response at sub 30Hz frequencies? Is this simulation pretty accurate? If so it sounds great and I think I have a winner.

I really like this one using a 15" PR

If you can afford it of course...

Well with room gain you'll probably be happy with the sub30 response... but if not there's always the option of a linkwitz transform circuit 🙂
Consider a ported alignment,extra LF extension.
I dont think a sizable 20hz port would fit on 2.5cubes,perhaps more like 3.5cubes easily-you dont want 100cm long ports doing a 90hz "Dong" resonator sound!

anyway - try to get lowest freq response. you'll not sorry.

Personally,the dpl12 is ofcourse designed for ultra low frequencies.why not take full advantage of this by tuning to 16hz on 100-135litres.
EQ is always needed to try and fix in room response however..
it can handle 200watts with this tuning and no eq.
(id need 2 or 4 of these to get the output at a linear enough level)
😀 😀 😀 😀 😀
edit: PR required for low tunings,as airspeed is too high on acceptable sized ports
