PROAC D48R Bass Booming

Dear all,
                I am updating the latest development.  I sold the BAT VK 3000 SE and replaced it with a pre-owned Karan KAI 180 Integrated Amp.  I tried plugging the Downward Port with Foam.  Trust me, 80% of the Bass boom is gone and now I am listening bass-heavy tracks without much difficulty.
                 My sincere thanks to all.

Great news and happy to hear it worked out for you

these speakers very much. But the only problem is Bass-boom and because of that, some tracks are unlistenable.


~~~~~~~~~~~~~~~~~~~~
I think ProAc uses Scanpseak woofers, 
Yes?
WEll this **boominess* in upper bass, is part of that drivers character.
Which is why I went with Seas Magnesium to avoid the upper bass resonances.
I think Wilson also uses Scanspeak.
Scanspeaks offer incredible low bass. Tight punch in drums. 
Every driver has its tradeoffs.
Paper composite  vs magnesium.

Oh I am sorry,
The woofers are not Scanpseaks,, Not sure which lab makes that driver,..
I’d never have gone with a speaker such as that midbass.
I only trust Scanpeak, Seas and SB Acoustics.
Before I buy any speaker I need to know who makes the drivers.
I never buy based on a name of the company.
A bit pricey to have this type of coloration going on,
btw they are made in England, home of B&W, another speaker line that i find upper bass has coloration = fatigue.

at 11G's , I expect nothing less than perfection  throughout entire spectrum

Did you read the review you posted or even hear these speakers?

It appears the OP has a room treatment or placement problem.

It looks like he has it resolved which is great news.
