Have you tried giving the BHS 8kw from your SP rack amp?
Not only will you embarrass yourself if you blow up a driver, to add insult to injury, you've already told the manufacturer how much more power you're running than he recommends.
But really, apples and oranges. Remember that I'm using a smaller enclosure than the original HS24 called for and use the DSP and extra power to add a Linkwitz Transform to get better performance out of the low end. As has been pointed out, the newer HS24 mkII have more motor force and work better in the smaller enclosures, almost like Nick had me in mind when designing the update.
With that said, I would give the FTW21s the output advantage since they have the raw displacement advantage and are colocated. Frankly, they should win. But the BHS-24 will more than hold its own. But definitely be careful, even the BHS-24 can be burnt up by 4,000w if too much power is dumped down low for too long a period of time such as that Lone Survivor Chopper Scene with 6Hz/10dB hot signal. If you're pushing the subs hard down low, I'd keep it to shorter bursts but even better if you use a more balanced signal that will allow the driver to keep itself cool.
No, I find the SP1-4000 is more than powerful enough for even the BHS-24.
I use the metric of subs per rack mount amp though I know many of you seemingly use number of rack mount amps per sub. LOL!
