Title: Da Sub .... Da Bass....
Post by: 2bigears on 17 Jan 2015, 08:20 pm

 :D   Danny,,,, i'm using a set of V's for bass units for Mag 3.6's.... Should i position them head-on like reg speakers ??  i thought bass was non-directional....     :D    first thoughts and impressions are good.  i just have one set up at the moment not pointed at me. i will set the other one up soon to try  multi sub ....   :D   any help thank you very much,,,,   :D

For Super-V's point the subs at you.  OB bass has a directivity pattern with the peak on the speaker axis.  The sides are a null.

 :D  thanks,,,,  so why are both drivers not pointed frontward ????   :D

That is to balance weight in the H Frame. 

Both drivers are working in the same polarity, so they move the same direction relative to each other even though they are reversed in direction.

Won't matter.  Maggies go low enough that the big drivers would be perfectly fine with them.  But if you want a narrower profile, three 8's will be OK too.  Main thing is to use OB subs, to match the radiation characteristics of your Maggies.

 :D   i was thisssssss close to selling the Mags....  till i married them to ob bass.   holy shit ....
           so no difference in output or richness between 12's or 8's ????   i think a smaller floor print would make me happier ,,,,
               the old simple thought process makes you think bigger is better , smaller is faster,but they are servo ,,,, :D   
                 or i can simply cut the tops off the V's and sell those ..   hummmm  :D

My GR OB subs are also paired with magnetic planar speakers, but Eminent Technology LFT-8b's (crossed-over at 180HZ and used in place of the ET's woofers) rather than Magneplanars. My Tympani IV's are too big for the room I now have! The OBs are THE subs for all planar speakers, magnetic, ribbon, and ESL.

What they said, and for your application I would stick with the 12's over the 8's.
