Subwoofer boom is too much for me...

I’ve done it with different results but IME a properly built sub (ported) should not have a stark difference than a properly built sealed one.

@johnnycamp5

The issue isn’t the quality of the sub. The issue is the amount of bass in the room with this particular sub. Sealing a port will raise the lower cut off, and this may help the OP balance the bass properly.

As I’ve written lots of times, audiophiles are conditioned to think we can glean insight into a system’s response by specs, but in truth bass response is hugely variable and specs go out the window when it comes to integrating a sub into a room.

Below ~ 60 Hz speaker specs don’t tell you a thing once they are in the room.

Agreed

I should have made it clear that only after extensive room treatment (bass traps)

I suppose I have tunnel vision that way…

I would not even consider positioning of sub or subs until after bass traps and/or treatment…

I did do it once that way though…

The room shape was atrocious as well- 15w x 28L x 7.6 high (all plaster walls also bad hard no lossy surfaces) 

only became somewhat acceptable after 4 subs…but the ringing was still generally unacceptable…

Well, I have to say I took two washcloths and stuffed them into the ports of both my subwoofers and there is a big improvement in sound.

I have subwoofer in from DAC amp and out to bookshelf for both channels.  Sounds great now.

I still think a good pair of floor-standers would sound better, but for now, I'm happy.

1) Auralex Lenrd bass traps from floor to ceiling in the corners of front wall (see pic in my virtual system)

2) An isoacoustics or ASC stand for your sub 

3) The DSPeaker 8033 sub eq device

This has worked for me every time I've set up a sub, whether it be REL or another brand. The idea of keeping the crossover as low as possible while volume high was tough to swallow at first, but now makes sense. 

Subwoofer tuning

And yes, I have bass traps and such.
