How about it
The Dayton 15" IB woofer seems like only a halfway IB woofer as it seems to work well in just around 500liter closed
-3db around 25hz, which is pretty good fore a closed design
Which means that 2 woofers in isobaric pushpull would "only" need 250liter
Mind you, its just a quick calculation, I havent checked it carefully
Backside is the high price

Just a word of caution
Seems very sensitive to specs variations
If specs are just slightly off from the listed, it could go completely wrong
I suppose woofers needs to be carefully measured fore thiele/small parameters
Woofer tester seems like a good investment
Would be nice to get a custom IB15 from AE speakers, with accurate specs to suit the design goal, and it seems like much better quality

Hi GM
Im not sure what it is you suggest
My software deny the 6th order BP, due to the high Qts
And a simple BR with isobaric ends up at 500liter
Simple closed(isobaric) would be 200-300liter, depending on driver specs
I suppose the calculated closed box would be the backchamber size of a 4th order
Thats fore Dayton 15IB
Dont know about the AE, as it would need be a customised driver with bigger magnet, getting Qts around 0.5
Am I missing a trick somewhere ?

Thawach said:tinitus your drivers are not suited for BP. very high QTS i never saw who made BP.
thanks Thawach, but have you read fom beginning
My suggestion was isobaric closed
And idealy have custom made modified AE 15IB
Maybe GM just meant BP with different woofer, I guess

Greets!
If I meant another driver I would have said so.
I was suggesting a 4th or 6th order BP for the Dayton to average out any specs variation with isobaric loading.
Get a more flexible box program. You can do one type of 6th order in HR (both vents exit the cab).
It could be, but with a BP you trade BW for efficiency and vice versa, so it just depends on the gain BW or max box Vb desired. At 250 L it would be a narrow BW with this driver, but the upside is it shouldn't run out of Xmax at rated power and hit near 120 dB peaks down low if you have the amp power (at least 1.2 kW).

Ok, thanks fore clarification
Yeah, I know, have to get used to a better software
Anyway, I dont care much about exstreme SPL, but nice to know
Only thought this as maybe being a nice "musical" sub, or "tuneful" as some prefer to call it
Responsive might be a better word
But so far its only silly words
