Issue with ProAc D40 speaker - any suggestions to resolve the issue

Hi,


I recently bought used ProAc D40R couple of months back, and driving them with Bluenode streamer —> Digital Audio company Marachino Class D Mono blocks.


After a month or so I realized that absence of the sound from one of the ribbon tweeter, showed it to local audio equipment dealer, they fixed the issue (it was loose tweeter harness wire), now I get the sound from both the tweeter.


Recently i compared these speakers against my exiting DIY Audio Nirvana 8” Alnico single driver speaker using ‘Spanish Harlem’ Track by Rebecca Pidgeon, to my surprise Audio Nirvana sounded more clear and I can hear all the details especially shakers in the left back corner and all other details while on ProAc D40r I can barely hear all those tiny details in the background to me that should not happen with ProAc being such great speaker especially with Ribbon tweeter, so just wondering What could be the issue, Can it be a Crossover Caps issue (as the person I bought these from mentioned those were in storage for almost a year and I read it somewhere here on audiogon thread that caps in crossover may go bad if you store it for long time). 

Really appreciate any recommendations/remedies to resolve the issue, eventually i will have take it back to audio dealer but just wanted to check on forum that if anyone else experiences this kind of issue and what was the solution.


Thank you,

Thanks for the suggestion Jaferd, looked at the boards (inside for the speaker binding post) and those looked secure as well.

Took the speakers to the local dealer, really nice Guy (Who fixed the tweeter connections a month back), we connected speakers to Naim power amp (not sure which one) and he listened to the song that he normally use to evaluate the speakers and told me there is nothing wrong with the speakers and eventually we listened to ‘Spanish Harlem’ Track by Rebecca Pidgeon as well, at the time at the shop i was able to hear the details those were missing at home (shakers in the background) .. the reason I believe is that volume was way up (I normally do not listen at that volume at home), as well as there was huge space around the speakers behind as well as on the side .. which is not possible at home. Brough speakers home and listened at high volume i can hear the details but only at high volume (bass is more pronounced as well and sometimes overpowering at high volume), Audio Nirvana single driver speakers are more reveling and forward sounding, as those are high efficiency i can hear those details at low volume. Will give it some more time will play positioning as well as with the cables/other components will look into getting the better DAC / different pre amp (currently the bluenode directly feeds into Class D mono blocks).

Thank you for all for helping me out figuring out what’s the issue with the speaker (looks like there i stone except that Audio Nirvana are more efficient and more detailed at low volume than ProAc’s)
