Had a brief listen many months ago, it actually sounds good. Warm, bassy, with a fairly good soundstage. I would like the sub to be tighter in its presentation as the bass lacks texture and can indeed bleed into the low-mids quite often however.
It's a very barebones soundbar, sound quality first and everything else second.

The problem with the SB23SW is its functionality. It's really thick and that means you either need to be hanging your TV or have it on a pedestal, because the soundbar WILL obstruct vision to ANY TV under 60". Also, because it has no display, it means you have to go by memory to set up your functions. Not a big deal if you're tech savvy enough, but the majority of people who would buy a soundbar wants simplicity and this here could be a deal breaker. Not knowing what you press and screwing everything up, is an issue for many, many people.

Lack of HDMI ports (which other competitors at the SB23W price range offers) is a downpoint too. Pioneer could easily fit in 2 HDMI ports with a switch with the depth it has on the soundbar, I have no idea why they didn't. It wouldn't have hindered sound quality anyways.
Then there's the price, don't know why SenQ is selling it for RM1.7k but a soundbar like this isn't worth more than 1.2k.
