Have you time aligned it with your mains at the crossover point? Makes a pretty big tactile difference at the crossover point if you are out of phase between transducers.

No Trevor but then again, I've had that beast all over my room and besides, other subs I've had in there weren't time-aligned either.

It's worth a try. Physical location affects the loading of the room but not latency. The amp/driver delay may have been more agreeable with your mains (by accident) with the other subs you messed with.

The delay on the subs in my room is ~20ms (or 20ft) behind my mains without correction. Without correction they are over a full rotation behind the beat at 60hz and out of phase by 390 degrees lagging or so. This related to a 3db loss in-room.

In a worse case scenario you could be down as much as 12db at the crossover frequency. No kick possible.

Understood but then again, I can turn the gain on both my receiver and the 600 right up and still no kick! I remember when we were watching the WOTW pod emergency scene at your place and I had flappy pants and sore nuts.

there is your solution. snag it while you can.

Trevor what sub/s are you running. Did you find that the DSpeaker improved midbass punch at all. I have a pair of 12's in my midsize car and a ton of power and they punch you but good . The 2 10's in my theater just dont have the midbass punch. I see many people on AVS building midbass modules to get that punch in the chest from the 100hz range. In my previous car i had a hatch and i faced a 10 towards the back of the car and that thing absolutely pounded, nice back massage The bigger the room the more sub you need.

I definitely would if I had the confidence that it would do the job.

No such thing as too many subs . Check out avs and look at building or buying a MB module and use a minidsp box to put a highpass filter on the low bass.

Trevor, I need 4 of these please

I was running a pair of sealed SVS sb12-nsd subs in a 12x17 room. They loaded it hard. They would open the furnace access door and freak people out it was a ghost!

The DSPeaker improved clarity and reduced bloom at the expense of output. A better result with Dirac, although Dirac did properly time align the subs to mains which helped upper bass. In the current room at 14.5 x 22 the same subs do not load the space to nuts sore levels. The triplet LCR towers we built sure help though with upper bass output. (Just an excuse to sneak a pic in. Lol) Can feel gunshots in movies.
