sorry I don't understand

I thought you just said the Delta's are better mids than woofs ?

but if using medio size woofers like 12" maybe consider SPL might suffer
and from what I understand SPL is exactly what you are lacking to keep up with your TH subs ?

or maybe look at PPSL designs ?

ok i think i understand you've got tapped horn sub's and two 60 liter two-way boxes with eminence 12's and a selenium horn top that are essentially direct radiators.
horn loading your 12 is the way to go.
something like a jbl 4560 would do nicely or a unity horn perhaps.

Just had a bit of a read on the 4560. Its most efficient above 200hz by the looks of it so id still have a gap in the bass range at around 90-150hz which is the exact situation im in atm.

Unfortunately, efficiency takes space. I have two midbass designs I use which are flat to 80 and do 105dB/W, and both are almost as large an SS15. You could do 102dB in half the space, but it's still a big-ish box at around 5 cubic feet.

When I set up outdoors I still havent established a "best" way for positioning everything. If I run the subs central it leaves me with no choice but to run my tops on tripods. However running my subs two per side gives me enough height that I can run my tops on top and thats where I could certainly run a bigger, heavier top no problems.
If I cant pick a distinct sound benefit then maybe I should run them for optimal setup?

Sorta missed my own point just there,
If I run each side as a big stack id remove the issue of the mid cab having to be on a tripod.

what crossover frequencies are you using?
i'm not sure but do the ss15's suck running up to 200 hz i've done heretic things like running Cerwin Vega B38's as high as 500 hz.
so i guess i'm trying to determine why you can't simply raise the upper limit on your sub's?

ps in vertically stacking two ss15 are you placing openings together,apart,same side?

I use a mini dsp for crossover duty. The problem is volume. I feel the subs run cooler and go louder when crossed no higher than 100hz.
