I have the audio components of my rebuilt HT system pretty much in place. Here's what I have to work with:
Denon 3600 and Marantz 7205 for 7.2.4 setup with front LCR, side and rear surrounds, mid and rear height speakers.
Room is 26.5' long, 12.5' wide and 7.5' high. There is no room for subs on the screen wall.
PB16U and PB13U subs
Ultra towers and center
Ultra side surrounds
Prime bookshelf rear surrounds
Prime elevation heights (4)
I have not yet run Audyssey. What port configuration should I start with on the subs and the Ultra towers?
The PB16U seemed to only come with a single foam plug, why?
Merlin suggests 50hz crossover for the towers with PB16, agree?
Do I really need UMIK1/REW to get the most out of my system? I'm not set up for it at this point.
I will have the PB16 near field right behind the single row of seats. I wasn't originally planning on having both subs, not sure yet where to put the PB13. Obviously it's big so it can't just go anywhere. Sound aside, they don't look that great side by side because of the different dimensions. I could sell the PB13 if it doesn't really contribute.
I'm running the subs on wireless soundpath connects.
Experimentation is ok, but I'd like to start with a well-reasoned sound starting point. Thanks!
I will make a few comments to help you get started. First, I would probably do my initial calibration with just the PB16. If it is already rear nearfield in a 2500^3 room, it may be enough by itself. And, you will avoid potential integration issues that way. You can always try adding in the PB13 later, if you want to, but at that point you will already have a listening baseline established to compare with the sound of the dual subs. You can calibrate the PB16 in either port tune, borrowing a plug from the PB13 if you want to use Standard mode. (Meanwhile, contact SVS, and they will send you two more port plugs for the PB16.)
There is some advantage to calibrating in Standard mode, and then switching to Extended mode afterwards, in that Audyssey won't EQ away quite as much of your room gain. You could achieve the same effect by establishing a HPF (high-pass filter) at about 20Hz, and then removing it post-calibration. But, I think most people may be more comfortable just switching modes. If you end-up using REW at some point, it will be a lot easier to make sense of the whole room gain issue.
You won't need to establish a port tuning mode for your speakers. Their port tune is not a variable. It is set by the factory and integral to the speakers' design. The lowest crossover I would personally consider for those speakers is 60Hz (regardless of what Merlin says), and Denon/Marantz AVR's don't offer a 50Hz crossover anyway. The next crossover choice below 60Hz is 40Hz.
There are multiple variables involved with selecting crossovers, including the inherent capability of the speakers, how they interact with the room, and their relative capabilities to play mid-bass frequencies, compared to the much more powerful PB16. You will learn a little bit about your speakers' interaction with the room from the initial crossover set by your AVR. Afterwards, I would probably start with 80Hz crossovers and see how that sounds. You can, and often should, go up from wherever your AVR initially sets a crossover. You should almost never go down.
The Cliff Notes on the the first page of the Guide, in my signature, will give you some additional tips to help you get started. At some point, experimentation will still be your best friend. But, it can always be informed experimentation, and other sections of the Guide can help with that.
