Stereo Subs - Do they need to be identical?

I'm thinking of getting a couple of subwoofers to mate with my MBL 121 monitors. Generally, I've seen setups where people use two subs of the same brand and size. I'm wondering whether it can make sense to use two different sizes. For example - a Venoyne DD12 and a DD15. I'm likely going to go with Velodyne DD series or JL Audio.

In particular, I note that the big Velodyne 1812 uses an 18 inch and 12 inch woofer, with suppsed benefits in terms of speed (12 inch) and extension and depth (18 inch).

Again, if using monitors, stereo subs next to them is definitely the general recommendation. And it most assuredly does matter that much!

Using two different size subs can be very helpful in evening out room nodes. Place them at opposite ends of the room. With monitors as mains, I would use two identical subs. Proper integration is way more than twice as difficult, but the effort is worth it.

Following the advice of mfgrs who know much more than I has worked too many times to count. Perhaps you are using monitors too close to the back wall. In theater applications asymmetrical is the way. Please try what these folks (mfgrs) recommend first before dismissing it based simply on theory.
