Experience with stacked subwoofers?

@dbastin Haha. Yes I guess you could count them that way. I certainly don’t lack any base in music or movies and the room is loaded effortlessly. I integrate them using an active crossover using 12 biquads per channel made from using Room EQ Wizard and Multi Sub Optimizer. They are all time aligned, adjusted to eliminate room modes, etc. I’ve got better base than the megabuck systems I heard at AXPONA. It is musical, accurate, no bloat or notes that sound out of key, it’s natural but will shake the room on big music transients or explosions in movies. I wish the younger generation was into this. It’s such a cool hobby, people are blown away hearing it but aren’t interested in anything technical or how it works. We all prioritize how we want to spend our time and money. 

@hifidream    Do you know of a published manufacturer frequency response ( ex. -xdB@xxHz ) measurement for Kinergetics SW-800's?

I get led to an SW-800 User Manual residing at Hifiengine but I'm unable to log in.

@dwette 

 how’s the dialling in process coming along? Are you up to subs 5 and 6 yet?

 Is your description of the experience of adding subs 3&4 similar to what REL and others describe in terms of increased attack?

Hi @guysellingstuff 

Yes, I have the first four pretty nicely dialed in. Foundational bass sounds great, and the mid bass attack and response are much improved. The soundstage has improved considerably, and is more three-dimensional. I can especially hear that when playing large scale orchestra music.

I'm still waiting on the third pair from my dealer. They are their last demo pair, but an amp was damaged and they have ordered a replacement from REL. As soon as I get them I will add them to the stack and work on dialing them in and fine tuning the final array.

I had been thinking about doing this for a long time but didn't want to spend the money at retail cost, so I'm glad I was able to get two pair of the dealer's demo array.

Nice!

sorry for all the questions but how have you positioned them relative to your speakers? 

Have you put them in the corners of the room or next to the speakers on the in/outside? In my research I’ve seen that the location seems to vary from what rel recommends in their line array setup video
