True sound test of this speaker can be found at https://youtu.be/DUyh6SxWsK8
That is how it really sounds.

Love it! The passive radiators work better now please Keep it like that.

@PlatinumEagleStudios

For smoother bass, try flaring both ends of the port and sealing the port into the enclosure to reduce air leakage. Flaring the ports will reduce air turbulence. When the port has sharp ends, air will not pass through the smoothly which results in muddy sounding bass that gets distorted a bit at higher volumes. But, when you flare both ends, it will cause the air to pass through very smoothly witch in turn creates smoother sounding bass that is more distortion free. I noticed the bass in this video sounded a bit too punchy and a bit distorted so try flaring both ends of the port like I mentioned, as this is just a suggestion :-) You'll notice a difference in the sound quality for sure. Very cool design though. Great work :-)

Still better than hopestar

@simo0250

The passive radiator is the best choose

@baconandbullets

Needs two passive radiators instead of port. Will drastically increase your bass or one large passive radiator if you can fit it on the back.

@pbz7455

Id so buy one of I can!

@Festyxr4

I LOVE IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

@danielvictorpopescu138

what abount no passive radiators,only bass reflex ,i think the bass reflex sounds good but the passiva radiators influences bass reflex in bad and viceversa

@masprassaja3818

I think you have a space in that side to make a small bass radiator. For bigger room speaker port is better choice. If you ever seen deviale phantom speaker thatt cool speaker without port tube.

@ledfed1912

You will probably get less output at bellow the ports tuning frequency of 110 hertz then when it was sealed so lower tuning freq would probably be good.

@mayureshjadhav8002

What was your target frequency for port

@RonanAquilius

lol the bass sounds very distorted and rough

@mmtech9352

great man, I'm new to speaker building, and calculating the port area is one of the most daunting things to do for me. any tips on that?

@skizzarz

Have you made what that user asked for since? Bass radiator... would sound a lot better than that port! If you have, link in the description!!!

"Air exits the port with enough velocity to move a table tennis ball"

Wow .. 

So strong 😑

@lucaspollak9136

What's the name of the calculation website?
