PROAC D48R Bass Booming

@gnanasekhar,
Did you manage to move the speakers? Any changes? 

If you make a equilateral triangle between the speakers and your listening position, things should improve even more. Have you thought of getting some corner traps?

@rego,I agree. And that is what I am suggesting. Placed along the 17' wall, he can try to move the speakers at least 4.5' from the side walls. That leaves 8' between the speakers which is ample for a room his size.

@gnanasekhar,
Are the speakers placed in front of the long or short wall?
Can you move them 24" from the side wall? Also Can you move them 50" from the front wall. Also try with the classic ProAc toe-in; which is to angle at the listening position with the "inner" side wall slightly visible from listening position. If that does not work, try to aim them straight ahead.
Looking at your profile, I think you have marble/til floors and thick concrete walls. So bass trapping in the corner will also help. The bass on these babies is certainly not "loose". It is super tight if the right.
The IsoAcoustic Gaia II will certainly help providing definition to the bass.Try to adjust the speaker position. The more you get it "into" the room, the less bass. Do your best before your decide to part away with this PHENOMENAL loudspeaker. Good luck!

@gnanasekhar ,If the speakers are in front of the 17' wall, then you have more than enough room to pull them close together. You can easily pull them 4' (each side) from the side walls and still have 9' between them. Which tells me that you can have the flexibility to pull them 4.5' from the side walls, and about 36" from the front wall. This should reduce the boom. In this position, your chair should be almost up against the back wall. So a pair of Monster panels from GIK (or other equivalent product available locally) should help you reduce the overall boom.I have got great results from Herbies products. Email them and ask for recommendation. My guess is that one of their product will help "tighten" the bass. Ask them for a product that can be used with the speakers spikes. Alternately ask them for suggestions, to place the speaker on a product with the spikes removed, since you already are on tiles.Is this a closed room? I remember a thread where you were guided to @jperry room (with similar dimension as yours and he has D40R). But I believe that @jperry room opens on the other side into another room. So the bass waves have more room to dissipate.Do keep us posted on if you were able to change the speaker layout and the results.

@gnanasekhar ,Good to know that your issue is resolved. As a fun track, try to listen to "Jazz Variants" on your speakers.

@mozartfan,Have you personally listened to the ProAc D48Rs?
Unless you heard a component you cannot make judgements, because you are only "assuming". You must be aware that tons of DACs use the ESS SABER 9038 chips. Do they all sound the same? Looks like in your world, one size fits all :-) These D48s need room to breath and OP has taken steps to correct the issues that he had.

Hi b_limo,Hey hope you are doing well. I read a user feedback on your system after he visited you. Looks like your patience paid off very handsomely in terms of musical satisfaction. Enjoy your music my friend! 👍🏼
