Scansonic mb3.5 vs mb5b


Just wondering if anyone could share some light on why the mb5b costs significantly more than the mb3.5b which actually digs deeper in the low frequency area. I understand that the woofers and midwoofers are run in series to improve power handling etc.. im just curious why the 3.5 costs less than the mb5. I know audio is more than just about the measurments, but what makes the mb5b more special than the mb3.5b (which has a lower price and wider and lower frequency)
Thanks in advance for any and all knowledge anyone may have on the matter.

I asked Raidho this question.  Pricing differential is driven by higher end drivers and larger cabinet.  FYI...everything from Raidho is made to order. 

They shut down for summer vacation from July 10th to August 3rd.  If you want speakers before August, we might be able to squeeze it in under the wire.  
Thanks verdantaudio for the very informative reply. Based on everything you said it makes sense why the mb5b would be more costly than the mb 3.5b. As it is, cost wise the 3.5 would make more sense as I would just be experimenting with the scansonic brand. But based on what u said its possible the mb5b would be a better fit in my current environment. Basically the room is roughly 20' wide and 15' deep w 8' ceiling. The only problem I have w the mb5 over the 3.5 is its a bit taller. 2 inches might not seem like a lot, but when it comes to tight spaces too much can be too much, if u catch my meaning ;)
Anyways, all that aside, at the moment I'm sporting Dynaudio C1 platinum for the front L & R. For their size the bass is astounding, and transparency is better than anything I've ever heard in my life.. period. Price wise I know the comparison is a bit skewed, but I still fear I'd be missing out on transparency and detail. Alas, the new Dynaudio Confidence 30 is thousands of dollars more costly than either scansonic model i originally inquired about. Im just wondering if I'd be content with any of the smaller floor standing models from scansonic or if id be disappointed in respect to my current Dynaudio C1 Platinums.
My first experience with Scansonic was a demo of the MB6 side-by-side with the Magico S1mkII and the Kaiser Chiara.  The Kaiser won but at $22K, was not an option for me.  I liked the Scansonic better than the Magicos.  They are very good.  That being said, I do think the MB3.5Bs will be a little less refined under 60hz compared to the MB5Bs.   I think you will find the MB5Bs are going to be brilliant and I think will go toe-to-toe with your Dynaudios.  

That being said, comparing the Scansonics vs. the Confidence 30s would not be terribly fair.  In that price range, the Raidho C2.1 is really the right point of comparison.  The raidho tweeter and drivers are a clear step forward compared to Scansonic and are brilliant in terms of detail and the imaging and soundstage are just obscenely good.  That being said, Raidho are my second favorite speakers behind my own line.  My Blackthorn 1 with go toe-to-toe with the Confidence 20 in terms of detail and transparency but I am not making a small floorstander yet to compete with the 30. 

If you have interest, we could do something like you demo the Scansonics for a few months.  If you really like them and want to step up to the Raidho's, I could give you full value back for the Scansonics on trade.
