it is possible to setup a decent 5.1 home theater setup for 4k budget.
including avr.

doing some quick research q990d seems like a good deal. 11 plus small speakers.

4k-ish 5.1 setup vs q990d/f. can fight anot.

now using 2 pairs of active speakers 4.0 setup. both swans.
my htpc, does not allow both dedicated sub or center to work at the same time.
its a realtek virtual surround thing. but seems to work while playing surround content.

now planning 2 upgrade something better. got pipu recommend i all in on a receiver. later slowly buy speakers.

my price references mostly from shopee choy store. no audio retailer in my area.

small room. maybe 3m x 5m. source volume 30-40%. speakers 50%

ok tq, i look around used market. see how.
i inherited 2 pair speakers.
1 kef brand, 1 aiwa brand, dk gooding anot.
maybe 20plus years old.
very dusty, the wood/plastic all scratched up.
no model number.
