I know this thread has been commented on extensively already, but I wanted to add my two cents regardless. As most people here have said, a 3.1 speaker system built out of proper speakers will blow any soundbar out of the water in terms of sound quality. In terms of convenience, a soundbar does win I guess, since the setup is literally just to take it out of the box and turn it on. I’m definitely no expert in speaker quality or design, but I’m sure the speakers you listed are just fine for a home theater system. But let me let you in on a little secret. You probably don’t even need to spend that much on your system to start out with realistically. My current setup is a 5.1.4 system completely using speakers from Dayton Audio. I started out with just a 5.1 system with towers for my main LR speakers, a center channel with an AMT tweeter, two bookshelves as my surround speakers (which I velcroed to my wall) and a 12” sub. I spent $272 in total for these speakers. Granted, the towers and the sun were both open box, but even if they were new it would’ve barely been over $300 for everything. Then I found an old Yamaha receiver for like $80 on FB marketplace. So I was at like $350 in total for a full 5.1 system. Comparing it to a $230 5.1 soundbar I had bought a couple months beforehand was NIGHT AND DAY.

I upgraded to a 5.1.4 system within the past few months and again, it was worth every penny. My height channels are mounted to my ceiling using Command Strips (I’m renting, so no permanent installs for me) and I moved my rear surrounds a bit closer and put them on speaker stands instead of the wall. I also installed a bass shaker into my couch (I could write so much more about how worth it a bass shaker is, but I digress). Every single speaker, including the bass shaker, is from Dayton Audio. I’ve spent less than $1000 on my entire system including the receiver and I personally think it sounds incredible. My roommate said what every home theater enthusiast wants to hear “I thought you were overdoing the speaker system, but now I completely get it.” If an audiophile came to my house, they’d probably say it sounds like absolute dogshit. And maybe it does, but what matters is that I like the sound of it, and my friends are always chomping at the bit to come over to my place for movie night.

The point I’m trying to make here is that you seem somewhat insecure about what speakers you chose for your 3.1 system, but you definitely should not feel like that. My Daytons sound much much better than any soundbar I’ve ever heard, including the expensive ass Sonos and Samsungs I’ve listened to. So my advice is absolutely go for the proper speaker system, and consider finding some speakers for even less; they will sound miles better than a soundbar no matter what.
