magnepans with a sub???

I have had good experience auditioning ML CLX electrostatics with their own ML Descent sub...which has presets automatically setup for melding with the CLX.

i have heard Apogee Stages blend well with top Velodyne.

i personally have owned Velodyne for 15+ years...currently DD-18. Give it a shot if you can. Bear in mind, Maggies require a LOT of power...and i am not sure if you are missing low, low end bass...or visceral mid to upper bass impact. If the latter, while you can get it from a sub...i think that you may be crossing the sub over too high then...which would mess with the fine blend of the Maggies. Instead, if you go for superb amp with enormous current reserves, you may find it adds dramatic punch.

what are you using as an amp?

Hi...i checked and see you have an ARC VT100...i cannot speak to this amp, except that i have heard the newer ARCs...at 100amps that may not be enough. I am thinking enormous Class A Solid State...Vitus, Gryphon, older Krell...these are amps which are generally quite sweet relative to other ss amps...but have a grip on bass and a power that is extraordinary. something to consider, as i do not know which area within the bass region you find lacking.

If you are looking for SPL and didnt get it, thats was do to a poor amp match. I have had MMG, MGiiia and MG3.6 all of them I could get peaks over 100db. I used Oddysey amps then upgraded to PASS

Now if your talking you want to hear under 30HZ then the sub is needed. One has nothing to do with the other
