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.

what about 4x15 BLs ....

These are the ONLY 2 options i am focusing on... due to weight
