PROAC D48R Bass Booming

Where are the speakers located? How close to a wall? If really close, move speakers out into the room to diminish the bass. If all else fails (assuming these are bi-wire speakers), bi-amp with another integrated amp so you have control over bass volume (I just remembered that my Proac D38s had a funky bi-wire structure. The top speaker-wire posts ONLY FED the tweeter. The bottom posts fed everything else).If bi-wiring practical, the VK-3000 makes it extremely easy with dual "pre out" connections. Another thing to try is plugging the bass port with something (foam rubber, pair-of-socks) anything to reduce the bass. The bass exits the speaker at the bottom so try stuffing some towels in the space to reduce output.

Try positioning them away from the corners and walls as best you can.Also experiment with your listening position.Plus what dweller suggested.

The speakers are 40" from the front wall and 18 " from the side walls.

Check all speaker screws and make sure all are tightened properly be careful not to over tighten. All the best

That’s the nature of these speakers I am afraid.

I had to let mine go because of excessive / boomy bass too.
