15" SSD vs 18" BTL for comps

[shizzzon 10+ year member]

I'm stuck and need some help.

Both of these setups will be used for music but i know both will be excessive for music.

I'm looking for info regarding the best choice for competition usage.

Here are the 2 options i have-

4 15" SSDs in 12.0 cuft NET with Flatwound ONLY.

or

2 18" BTLs with P Chamfer, HiXmcoil, Inner Heat Sink in 12.0 cuft NET.

Both setups are gonna be ran off of 2 3500Ds= 7,000w.

I know the SSDs may want the BP power with that much for daily but i wont be running it at that level for music, just for burps or short 30sec music runs in comp only.

I believe the options i chose for the BTLs are correct for the music\comp combo.

The main thing i'm confused about is-

is 12cuft for the 4 15s good enough to reign over the 2 BTLs in 12cuft? I know the SSDs have far more cone area but since i've never ran FI before, i dont know if 3cuft per 15" SSD is on the terrible side or if it's doable to boast over the BTL in this scenario.

thats about the same BTL setup i had, it was original BTLs fully loaded in 12cu ft net, was a good setup

i say 4 15s though

...

more cone area

be in the more upper end of SSD where as a BTL might want more to get good burp potential, both will be loud though

Sounds good. That's my next build then for this summer.

4 15" FI SSDs off of 2 AQ3500ds, swappable port for daily\comp

Music= 32hz, comp - tested to peak at 60hz dead on
