Based on your last post, it looks like you have more praises on the ProAc than the D9. But if the bass does not work for you, then go with the D9. Did you try the song I suggested? That should be a good test of what is "listenable" in your environment.Despite being a ProAc D48R, I would suggest that you have at least 24-36 inches behind these loudspeakers to breath, and at least 18 inches from side walls. If you cannot give them this much space, simply go with the D9. Think of your "best 4-5 albums" of all time and take time to play them on both the speakers. If the bass on the D48 is too much, you should give them up.
If you are able to live with the bass that they provide, you can go with them.It would be a disservice on my part to misguide a fellow audiogoner into buying the ProAc D48 just because I love them. You can also talk to your dealer to lend the D30RS and Spendor D7, since you are going to give him our business.
Good luck and hope you are able to take a decision soon.
