Everyone hears differently and has different values regarding audio purchases. I've heard several systems with REL 6-packs. I didn't like the sound of any of the systems I've listened to with 6-packs. I actually own dual REL subs, so I'm not being a REL hater.
Experience with stacked subwoofers?
I have seen a handful of responses to posts mentioning stacked line array subwoofers, like the stackable Rel 510s. Does anyone have a stacked subwoofer array in their system and can speak to their experience? The marketing hype that Rel puts out about this has me intrigued. Their explanation as to why it’s awesome makes sense, but also I want to go beyond the marketing and hear about real experiences before I drop a bunch of dough on something like that.
