I have 2 12" RD classics sealed at 1.25 net each. They get decently loud and hit everything with extreme accuracy. They sound pretty good too to me. I listen to a lot of metal with extremely fast kick drums and they easily keep up with the fastest. I wish they got lower, but if i put them in a proper ported box im sure they would pick up some low end and overall loudness.
My opinion probably isnt the best because I havent heard many good setups before.
I live in the apartments right across from logan. Well I just want a little beat in the trunk. Just trying to decide between these or memphis PRs. Thanks for the replies tho
