Interesting. I always thought a sub was perfect to get with a 6" KRK speaker. You feel like the 6" has enough bass response to really feel the low-end, even when producing bass-heavy electronic or hip hop?
i guess it depends on the room, and how loud you want to play. In a mixing / mastering situation, when you (are supposed to) have the volume low, i always has the sub on the lowest volume.
I thought i needed it before i got it, but after i got it, i dont. but its fun when you play finish mixed music at a high volume.
Pairs extremely well with the KRK Rokit 8s, and gives you the much needed sub listening for your studio mixes. Extremely fun to bring home for the first time, and it has plenty of amplitude to annoy the neighbors, hahaha.
