The first thing I noticed after running Audyssey on my Denon X6200 is that I had to bump up the volume 4db more on the Sub to achieve the same desired results I had at my last place and is now at max volume +0. Audyssey has my Sub at -5.0 in the receiver, which from what I've read here is right about where it needs to be. In order for Audyssey to even run, I have to set the sub volume -10.
Now before anyone says it, my bass isn't overwhelming by any means, but does run a little hot obviously. I'll run REW later today to see what else I might have going on, but at any rate, to the crux of my first world problem
. I'm looking for more of that thud in the chest most all of us here crave in our favorite movies and while I get it if I turn up the volume on the receiver past 62 or 64, I was hoping to get a little more of it by adding another sub. I've been eyeing the PC12 Plus and putting it near-field on the opposite corner of my room. I called and talked SVS and the first thing I was told is that I could mix in a PB2000 if going near-field, just up the volume to match. From everything I've read here, I thought mixing Subs of different calibers was not a good idea.
Attached is few pics I just took to give you guys an idea of what I have going on. (Yes, I'm still in the preliminary stages of acquiring some decor for the walls
Thoughts? Words of Wisdom?
Thoughts, definitely! Wisdom? I'm not as sure.
I'm not certain, from looking at your photos, which corner you are planning to use for the second sub. Would you please guesstimate (or measure) the distance from your existing Plus, to the MLP, and then do the same thing for the corner you plan to use? Offhand, I am not seeing a corner that I would characterize as "nearfield".
The advice we get when asking other people about this sort of thing can vary, including with whom we happen to talk at SVS. Personally, given your description of how hard you are pushing your current sub, I would definitely not be looking to go down in power. And, I also wouldn't want to sacrifice any low-end extension, which only gets better as we go up in power from the PB2000. So, I would be looking at adding at least another Plus. And, if I could afford it, I might go even higher up the food chain.
It isn't so much that you can't pair subs which are one model apart in capability. It's more that you don't want to pair down from where you are now. In your circumstances, I would suggest at least pairing equally, or if possible, pairing up to an Ultra. If your second sub is going to be fairly close to you, I would also suggest going with a PB rather than a PC. The direct pressure wave from port and driver, of a nearfield sub, can be much more intense than from a similarly placed down-firing sub like the PC. Just a thought.
Again, assuming that your second sub will be much closer to you than your existing one, I might replace the existing sub with either a PC or PB12 Plus, or a PC or PB13, and move the Plus to a more nearfield position, both to equalize the SPL output difference, and to take advantage of a closer proximity to the port/driver, if you do decide to get a PC. You have numerous options here, starting with your original plan to get another Plus, although as noted, I would make it a PB, unless you want to put the cylinder up front. I have a nearfield PB13 (2' behind my recliner) and it makes quite a difference in tactile ULF, compared to a PC13 I used to have back there.
I hope this helps.
