That is certainly a better value option if you can still get the drivers and amps for a reasonable price over there.

I went the DIY route as well and build 2 of the VBSS style subs. I wanted to build something bigger, but my wife vetoed that. AVS forum has plenty of information on design options you have.

It absolutely makes a massive difference. But you unfortunately need to spend $500+ on a subwoofer to get something that outputs the full range of what you can hear. There simply are zero subwoofers below that price point with adequate output in the 20-35 Hz range.

With regards to 4k, I can understand not caring for it. I agree that for most viewing distances and TV sizes, there’s not a massive difference. However, 1080p TVs also don’t have good HDR or the wide color gamut.

Upgrading to a 4k TV with a good peak brightness (at least ~1000 nits) will be very noticable. I especially notice it in anything with fire. It looks so much better on a 4k HDR TV than on a 1080p SDR TV.

My opinion is that the next biggest upgrade is a receiver and a 5.1 (or at least 2.1) sound setup.

I disagree, because there are some fugly people out there. Boobs are certainly no longer good boobs when the nipple is below her belly button.

It seems to me to be worse manners to just leave your snot as leaking out or making you sniffle. Better to get it over with rather than make people listen to that for minutes to hours.

Being friendly is far more effective than trying to punish people to make them agree with you. Especially when there’s no immediate and obvious consequence of their individual actions.
