Hey all looking to build 2 21" Superscoopers using a pair of Pyle PDW21250's.
Whats everyones thoughts and opinions on this configuration?
Also I'm thinking about using an Behringer Inuke power amp, which model would be suitable to power these to there full potential without blowing them?

The superscooper is designed for a Precision Devices PD.2150 and might not work well with other drivers. The large difference in magnet size is the first thing to suggest that these woofers have non-comparable Thiele / Small parameters.
Thanks guys looks like I'll be saving for a bit longer for the PD.2150. Is it worth it?
I got 2 quotes for scoops to be built one was minimum of 20 boxes at $600 each the other 2 boxes at ~$1000 each.
Anyone in Australia interested in a super scooper box 😛

Let me rephrase that: will it sound better than in a regular (correctly calculated) ported box.
Depends on what you mean.
A scoop is a BLH and normally designed to only load the bandwidth below its mass corner [2*Fs/Qes], so for a given low cut-off it won't load as high up as one designed for a lower Q driver like the PD, ergo the filter chamber will be larger, ditto its throat, mouth.
WRT sound quality [SQ], a lot depends on what XO point/slope you use and since the BLH will roll off lower due to its higher Q plus being a BLH, then ideally it will need to be XO'd lower than the BR, but will have a much more powerful mid-bass. In short, if you want to XO at a typical 500 Hz or higher it probably won't sound as good.
Trade-offs, its always about trade-offs; my remark was merely about setting the record straight WRT whether its specs were suitable for a BLH, not recommending doing it and due to having such a high Vas [if true] combined with a probably higher Qes than published, it will be unacceptably large.
I assume this is for a prosound app, so must factor in thermal power compression raising its effective Q, further lowering its HF roll-off, increasing it's size long past the point where you're much better off buying either multiple Pyle drivers loaded in appropriate BRs or use fewer high power PD or similar [mid] bass horn driver in scoop bins.
