Thoughts?
For reference my room is a living room/dining room combo with a cathedral ceiling open to an upstairs landing; about a total of 5500 cubic ft.
Hey now, fellow SAM1s owner! Going to follow suit again and end up with an XV15 or two now?
Maybe initially try one XV15 next to your main seat. After consulting Tom, and based on my listening habits and near field placement plans for the new sub, his recommendation is to go with a single XV15 (with a 2nd XV15 under future consideration) . I have an older a/d/s sub still kicking that I may or may not incorporate initially (certainly I can experiment and validate other people's opinions that more subs are better for room smoothing, or that two unequal subs can potentially compromise the better sub's performance, hence best to go with two or more identical units).
I have a very open great room, well over 6500 cu. ft. total -- 24' x 14' with 16 foot high ceilings, and it's adjacent to an 8 ft. opening into a 12'x14' entry foyer and another 8 ft. opening into a 15'x12' dining area with 8 ft ceilings. Also opens upstairs to the loft, sitting above the foyer, and 2nd floor that overhangs a small part of the great room. Open! My listening habits are 75% music/25% HT. I typically listen to music at 80dBs, sometimes cranking up to 90dB for very short periods. FYI: using my SPL meter, I hit 90dB at my main listening position at a volume level of -18 on the Yamaha RX-A3000 AVR. When watching bluray movies with a HD lossless soundtrack at the loudest level we enjoy, it's at -6. For TV viewing typical volume levels range from -25 to -15 depending on the content and surround mix.
So here's what Tom shared with me that clinched the initial purchase, given I was using a near field placement within 4 ft. of the MLP and placing the sub against a boundary wall: "In your room environment you could expect extension down to the 14-16hz range with clean output capabilities. If the subwoofer would be against one wall in your near-field scenario you can expect clean output capabilities of 115-124dB at the seats. This should give plenty of "headroom" to spare which is always a good thing of course. This way the subwoofer is always coasting. The bass will always have extremely low distortion and you'll have plenty of "reserve" if there is a sudden transient in the music or film that requires unusually loud output from the subwoofer."
I should receive my sub this week or next. Will share more once I get it setup and dialed in. Might even pick up a UMM-6 mic and get REW installed on the laptop so I can see how using dissimilar subs does affect the measurements. But initially I'm expecting to be into doing what everyone else here does when a new bass toy arrives, feeding my head and body a steady diet of bass heavy ear candy.
