I do not have the numbers in front of me but I think it would fall somewhere a little north of the Alpha for box volume. If the specs are accurate it should sound good...Really wide section of 130db+. That looks incredible, what’s the enclosure volume? And do these drivers actually sound good?
I will see about wider when I get a chance. If I went do the very bleeding edge of the 10" bracing rule I can go out to 33" wide before adding the third rail. Taller would knock the resonate frequency down, it looks good where it is at, I will try to keep that in tact.I can’t go any deeper than 24, is it possible to go wider or taller?
I’d definitely be down for trying one of these if this driver is really around 400ish like it appears
The price point is the thing with the 460 with it being capable of 11mm of excursion without too much distress. Both of them lose the nicerInteresting that a PA460 works in a Mini Dev, with a Vas of 402 liters, BL2/Re of 88.8, Cms of 0.19mm/N, and only 6mm Xmax, and you wouldn't recommend a PSS555-8 with a Vas of 444 liters, BL2/Re of 163, Cms of 0.11mm/N, and 11mm of Xmax in a Dev.
Honestly, I'm not trying to be a cheerleader for the PSS just because I bought 2, I'm really just curious why there is enough of a difference that one can be used but not the other. Is it just that the PA460 is stupid cheap and you feel the SAF is a better option at a similar price point to the PSS? The only real difference I see between the SAF and the PSS is a larger cone with a higher compliance resulting in a larger Vas for the PSS. The PSS wins out in the motor force factor category, and only lacks 2mm of Xmax. If the Xmech of the PSS was confirmed to be 19-20mm (which I don't think is too absurd to consider) would that change anything? I mean, the SAF Dev pushes the driver well past Xmax, way beyond the 70% BL range and that apparently works quite well?
FWIW, I am not planning on using my PSS's in a Devastator, it is just confusing that the PA460 can be used in a smaller volume Mini with a Vas that is not a heck of a lot lower than the PSS, and has a comparatively weak motor with higher compliance.
I also realize the PA is not the optimal choice for a Dev, but it has obviously been used to good effect in one.
33” is perfect honestly. I’m not sure what the 10” rule is, but I can go up to 36” if need be.I will see about wider when I get a chance. If I went do the very bleeding edge of the 10" bracing rule I can go out to 33" wide before adding the third rail. Taller would knock the resonate frequency down, it looks good where it is at, I will try to keep that in tact.
What would be a better driver for Devastator 21" Finalizer? the LaVoce new SAN215.30 or SAN214.50 ??
Also, I can't feel the ULF in my room so I thought at least get the mid-bass punch & chest slam, so is the finalizer the sub I need or I would be better with a mini Dev ??
I only have room for one extra sub, currently, I have a Rythmik fv15hp

Thank you for the excellent response, and not reading my response as a jab since it was definitely not meant as one. I have a decent knowledge of different subwoofer designs, but regarding horns/bandpass and the seemingly infinite arrangements possible, I am still on the low end of the learning curve. It is interesting stuff though, and I appreciate everyone on this forum willing to impart their knowledge to the rest! Go team!
33” is perfect honestly. I’m not sure what the 10” rule is, but I can go up to 36” if need be.
105db at 20Hz and the 114db at 30Hz. It definitely has the advantage. The mobile for the weekend now, plotting will be a bit. 110 and 116 for the Dual 15".
