B&W Matrix 802 series 2 vs series 3 vs ATC SCM40


Guys please help me decide between these fine speakers. I pretty much narrowed it down to the speakers mentioned above but if you know the one with as much or more authority and slam please let me know.
Thanks!

Series 3...Considerably better from what I heard///Had both.....If I remmember correctly the Series 3 had the IPOC system removed and was a cleaner more refined sound..The 3 also had better bass attack...Going from memory here..
Series 2 more bass. Series 3 more refined bass better attack. ATC SCM40 least bass of the three but most attack or in your face. They are all good choices.
