I am amazed that you’re able to get anywhere near 1k for an old AVR like that. But, good for you, I’d probably do it too. If svs is high on your list, I’d also consider a pair of PC2k pros. They’re only 16” in diameter, and can fit more places than many boxes. They’re also very light compared to box subs. The 3000 series(not micro) is the best value from svs, but due to size and weight, the PC’s might be better for you. They’re also cheaper, and dual pc’s will offer better performance and the potential for better FR. Considering the looming threat of an eviction notice though, it might not matter lol.
ETA: considering subwoofers, almost anything will be an improvement.
