Sure, but that's a rather large room, and I presume your listening distance is more than 1 meter?
Between three and seven meters. Would be quite strange to sit at one meter, in a living room that is more than 8 by 4 meter. SPL is not really that different across the room. Some time ago, I had the Adam T10s sub connected. Much more power and deeper bass. But not a substantial difference in pleasure across my music preference. My neighbours did complain, contact sound. So I tossed the downfiring t10s out. Big problem with the Adam T10s is the auto power off. It does that way too quick. I would advise against living room usage, it is not compatible with low SPL levels. In line with this, Adam is deaf to this complaint ;-) Surely, the high and low pass filters are in, footswitch. Great system, cinch/XLR in, cinch/XLR out for the 8030, great sound. Just crappy power off.
If any, I would buy the Kali WS-6.2, horizontally opposed woofers. This one does not have auto power off at all, so that will cost about 25 euro each year on electricity. In the entire life cycle, about the same as the purchase cost. Nice small package btw. Kali support replied quickly on my questions, it takes 12 watt idle, no power off. Hehe, and one sub is no sub, you need two, according to the REW simulations ;-)
In my living room, I have background radio on for some 20--60 hours per week, mostly at real low SPL. The 8030 is one of my best purchases ever, so much joy. For the sound, the build quality, small package, it is a bargain, a steal.
