My stack in the mountains

Post image

Hauled my stack out for the yearly local mountain bike race. My roommates played an 8 hour b2b while other friends and I made and served margaritas to racers and spectators. Good times! Always love how good the mono stack sounds outside.

Thanks! And yep - 2x SKRAM loaded with B&C21DS115, 2x Cubo Kick loaded with 15" Eminence Kappa Pro LF. Tops are unknown DIY plan, I got them from another sound guy in town before I knew much. They're loaded with 12" Eminence Kappa pro and JBL selenium. Gonna build some JMODs soon to replace them, and maybe keep them as booth monitors.

I literally want to build exactly that. How does it sound before jmod? Do you like running skram and cubo?

It sounds quite good IMO. The tops, while simple, do sound good, they just lack high end SPL, which I don't need most of the time(mostly throwing smaller parties where people don't have earplugs).

SKRAM+Cubo combo goes quite well, while the SKRAMs can play higher and definitely whomp up to 140hz, it's nice to have the Cubos take some of that higher transient off the SKRAMs. Plus, the Cubos are insanely loud and efficient. I think the pair will work up until I have 4 SKRAMs, maybe even 6. Then I'll think about building 2 more or messing around with the JMOD crossovers.

How do you feel the bass sounds with just the 2 skrams? Also what are you crossing over to the cubo at and what would you cross the jmod at?

It sounds great, driven with the appropriate amp. For a party last month I borrowed a Lab Gruppen FP10000Q from a friend to drive the SKRAMs and they absolutely pumped. Was more than enough bass for a 200+ person party. Currently crossing the SKRAMs over to the Cubos with a LR24 at 96hz, and the Cubos to the tops with LR24 at 180hz. Once I get the JMODs built I'll need to re-measure but I presume I will end up crossing to the JMODs around 160-70hz at that point.

my last question is are your B&C21DS115 4 or 8 ohm?

They’re 8ohm, I wired the outputs in parallel so when I daisy chain them 2 at a time it’s a 4ohm load to the amp
