Importance of phase and timing optimization when incorporating sub woofers ?

For incorporating a pair of sub woofers into a music system, how important is it to be able to optimize phase ( continuous adjustments and not just 0 or 180) and timing ( optimizing delay ) ? Reading on this subject, some say to get the best seamless integration, the two above factors are essential. REL is frequently mentioned as the most musical/fast/detailed sub woofers for music, however they only allow of 0 or 180 deg phase and no other room correction, as compared to Velodyne DD’s or JL Audio’s. I could utilize something like the JL Audio CR-1 crossover, but adding an additional piece of equipment into the audio chain wouldn’t be my first choice. On the other hand, the added benefit, might make the addition of a well made crossover a net plus ??? Regardless I plan on having my room/system measured to assist with incorporating what ever two subs I go with.
Thoughts from experienced users?

I started a thread a while back with similar concerns, and opinions were all over the place, as it seems they are here.

Most opinions were against the notion that phase and time were important when setting up a sub, or multiple subs for 2-channel music.
All I can say is that I’ve had the opposite experience using subs with my Dunlavy speakers. I’m guessing this thread will morph into a discussion about using multiple (4) subs in a ‘swarm’ arrangement, as the panacea for most bass evils, and I accept that in principle the swarm should work well. But I haven’t had any success with it in my system and still prefer a single sub placed with attention to phase and time integration to multiple subs placed with the golden ratio principle.

Good luck OP!
