I’ve been playing around with my speaker placement lately after receiving some extremely useful information about trying to eliminate nulls in my speakers’ frequency response. Up until today, I’ve been using a pair of KEF LS50 Metas high-passed in conjunction with an SVS SB-3000 sub. In part of my testing today, I toed the speakers back out a bunch (originally toed in to just about 5° off-axis, now they’re only about 10° toed in from dead straight) but also pulled the speakers out closer to me about 2” (so moved from about 50” to about 52” from the back wall). The speakers are separately room corrected with a DSPeaker Anti-Mode X2D, but I was experimenting with using the WiiM for bass management and a separate DSPeaker Anti-Mode 8033 Cinema for the sub. Anyhow, after making that speaker placement adjustment, I was playing around with different crossover frequencies when at one point I decided to try listening with bass management disabled and just use the WiiM Ultra’s room correction in separate left/right mode (not yet possible with bass management turned on unless you’re part of that beta test, and I’m not) mostly as a form of tone control (target curve Harman).
Well what followed shook me to my core…
I got up three times to check with my hand physically—my subwoofer was indeed not playing at all…yet I was getting full-spectrum sound. Full-bodied, with sufficient extension for music listening (probably not for watching Jurassic Park, but for music, definitely sufficient). In fact, the system just sounds marvelous. So I did more testing, I put on some orchestral pieces and really cranked it. Still full-bodied. Still hard hitting, and if there’s distortion under 100hz (see LS50 Meta review), even at 85dB peak levels, the low frequencies weren’t heinously distorted. And boy is there bass.
So now my subwoofer sits idle.
How is this possible? Who knew the LS50 Metas actually made sufficient bass and extended deeply enough in a room this size (looking how the system is oriented, we’re about 17’ deep by 25’ wide by 10’ tall with two permanent openings on the far right, with the system 2/3 of the way into the room on the left, with me sitting about 10’ from the speakers)
And why did bass increase so much from this placement adjustment, especially when I pulled the speakers away from the back wall? Did going them back out cause them to reinforce each other because now they’re more parallel facing?
