Hey all,

I have plenty of experience in the auto world but when it comes to home audio I am a newb.

We have two existing Memphis 15's and are currently running them off of one channel of our sub amp. We use to have a servo driven unit on the other channel but it repetedly fails so I have been tasked to add another set up. We are grabbing 2 18" SSD's and I am making two seperate new enclosures, one for the 15's and one for the 18's.

My question comes in how many cubes should I be looking at? It seems everyone goes really large but I dont wanna burn up the sub by not having enough resistance on the movement of the cone, so I was thinking 8 net for the 15's and around 12 net for the 18's. I was gonna do a slot port design on each tuned to 35 Hz...

Any advice appreciated, I will be sure to update you all with pics

Would you be using this for movies, or music primarily?

Need to know the application/goal. Why not sell the M3's and get 4 of the same?
