Default Procella P10/P15 Clones?

It has been a while since I last posted on here, during which time I have finally boxed up my Audio Drive 12" drivers into BK Monolith (passive) cabinets and currently running a BK XLS200.

However due to living room constraints I would like to try and achieve a 'slim' subwoofer that would be somewhere between the Procella P10 and P15, i.e. using a pair of 12" active drivers. I have initially thought, ahh 2 x XXLS 12", but I don't think that will work too well. Maybe 1 active and a PR?

Looking at using a BL BSBPV500 amplifier to drive it/them.

Thoughts?

Question SB Acoustics SW26DAC76-4 vs. Scanspeak 23W/4557T00

A similar design but smaller in diameter is

3. Scanspeak 23W/4557T00 SubWoofer 10"
23W/4557T00 - Scan-Speak 10 inch woofer long throw aluminium cone - Europe Audio
Scanspeak 23W/4557T00 SubWoofer - Revelator

Both have (SB Acoustics SW26DAC76-4 and SS 23W/4557T00) QTC = 0.707@Vb = 39.5 L.
The smaller heavier Scanspeak has [Sd]232 cm² vs. [Sd]312 cm² for the SB Acoustics. Max. level (dB) it's lower for the Scanspeak but it goes lower also (F3). Excursion maximized for the Scanspeak with Xmax ±13 mm (Mech. ±20 mm) and for the SB Acoustics is Xmax ±12 mm.

For the 12" Tang Band WQ-1858 QTC = 0.707 is reached with enclosure volume Vb = 86.5 L (1xdriver).

You can make a super sub with the passive of the SS and F3< ±20Hz for 55 L volume (Max.SPL 1.00 m/105.6 dB).
