As a reformed Magnepan 3.5R owner, they lacked bass. I added 2 SVS powered subs, but even with an active XO could not get a seamless blend.
I now have Emerald Physics 3.4s (open baffle 12" concentric woofer with 1" polyester tweeter), which do everything the 3.5Rs did well, PLUS excellent bass, but since my room is quite large, I will be replacing them with EP 2.8s which have 2 @ 15" carbon fiber woofers in a D’Appolito configuration with the same 12" concentric woofer in the middle
MSRP was $~3500, but can be found (if you’re patient) for < $1000
