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.

An awful lot of old people still voice “you shouldn’t need subs” and I think this was accurate in the days of Led Zeppelin, early Genesis, English rock and roll.  What I see these bands doing with subs on the recording side has certainly ended that idea. Pop music (Ariana and Sabrina carpenter ) - Americana ( Sarah Jaroscz) even country (post Malone/Jelly Roll/ chris Stapleton, Kane Brown ) -are working the subs hard.

I suppose nobody "needs" subs, but damn, they can make an huge improvement when you abandon need and go all out for want, and take the time and effort to dial them in properly.

I spend the afternoon setting up the first four REL S/510 of my six-pack line array....and damn does that sound good...and I still have some fine tweaking to work on.:)

And I am an "old people."

After the ten minutes spent locating my rooms two strongest standing waves I position the two twelve year old subwoofers within. The twenty minute Auto EQ runs while a Sweep Tone CD is played through the main speakers as each subs fourteen parameters are adjusted to both the speakers and the room simultaneously. Followed by a minor five minute manual tweak to personal taste all from the listening position, close the laptop and done. 

I'm not only old, I'm a lazy idiot. I still have that silly Columbia 'Sneakers' LP - that 'Cosmo' (Kramer) track, jeez. Best of luck with that. 

I added a six pack of REL Carbon Specials to my Rockport Cygnus (which have great bass already for size and price) about 6 months ago. The added bass support was fun with modern soundtracks, but the creation of the "space" of the venue was something I have never been able to access before. My wife thought here he goes again on a wild goose chase, but was immediately saying that she loves them. It is the most significant upgrade beyond different main speakers that I have achieved. Once you hear what they can do, I don't think anyone will want to go without them. It's so not about more bass, the first two subs did that. It's about how much more engaging the experience becomes. If you notice several top of the line exotic brands have 4 box speakers with two of the boxes containing...you guessed it, three woofers. This set up is similar to my six pack next to my Rockports. Everyone who can try a 6 pack of subs should try it. I can't imagine going back to just mains.
