Well not match but to be closer to the mid. Since the Volti Vittora is 105dB efficient with the bass horn. I thought integrating the mid bass with the mid would be somehow better with mid bass being 103dB instead of 100dB.
Situation:
Listening area is 45m2 (floorarea)
I'm planning an open baffle mid bass with 15pr400 (Got it years ago for a good price so not looking at any other drivers) (120Hz-500Hz)
Bass will be done with a closed sub I already have with BMS 18n850.
Bass and Sub Bass will be powered and 'crossovered' with miniDSP PWR-ICE250. ( <120Hz) one per side so. 4 channels total) So I'm assuming at the levels I play the amp can handle the 4 Ohm mid bass easily. (should I choose to go 2 mid bass per channel)
Mid 500Hz-6kHz=BMS 4592 mid on JBL 2380a clones.
High 6kHz =faitalpro 10hfak on sth100.
Crossover will use Crites 3636 to bring the mid and hf levels down. So mid and high with SE tube amps and as you can see a passive crossover.
Mid Bass open baffle because I baulk at building a box with current prices of birch ply and my poor woodworking skills. And Troels raves about the bass on his OBL15.
Question: should I got for an extra pair of 8 Ohm 15pr400 paralleled for an extra 3dB? Would be another 600 euro ex shipping. So what would that extra 3dB bring to the whole setup? In terms of subjective added value.
This is an end game speaker for me.

I'm not sure I'd use sensitivity as a reason to either double up or not. Besides, it's rare to have them line up that precisely that you won't be adjusting them anyway, not to mention the shaping you might be needing.
Just goes to show how much I still have to learn. I didn’t realize that at such low frequencies, any adjustment would even be necessary — let alone actual shaping.
It's just that the open baffle is an unknown. Not sure that response tilts, not sure of the power relationship etc.
Based on what is known, either way would be OK for me. Are other parameters of interest than sensitivity?

Nope, I don’t have another perspective — that’s exactly why I’m asking. I had this vague idea that doubling up could give a more effortless sound, and that more sensitivity would just be inherently beneficial.
I have very little speaker building knowledge...And while AI is amazing for certain things...It just seems to keep on cheering on my baseless ideas ..... 😀

You're not wrong, but the most you'll see of that effect is likely comparing compression tweeters to domes. Yes, woofers can go into thermal compression but it depends on the system, is it already sufficient.. and even when it happens I don't find it quite as bad as the higher frequency case.
So if I’m getting your point right, the impact would be minimal at the low power I’m using. I can definitely live with that — better WAF and less expense.
I guess a 15" driver, 3" coil, sensitivity of 99, a few watts into it doesn't sound like a problem. A 2" coil 15" can run into thermal compression if it is pushed.. but I don't want to get too far into guessing.
Probably a massive understatement for a unit that is meant for pro environments and according to the manufacturer can handle 400W aes. 😀
