Super-V build question - 3 servo drivers?
« on: 24 Aug 2011, 03:13 am »
I did some searching and didn't see a direct answer to this question.  Thinking I'm also not the first (only) one to wonder this, I thought I would post my question to the forum rather than send a PM.

What would be the optimal configuration of the cabinet/drivers if one were to build a Super-V with three servo drivers per side instead of two?  If the three servos were put in H-frames below like the reference plans, the coax height would probably not be optimal?  Assuming the rake angle built into the cabinets is there to adjust soundstage height, would this come out in the wash?  A W-frame with an extra baffle to keep the height down?  Four drivers on one baffle in a S-C-S-S arrangement (kind of a really big M-T-M with an additional woofer below)?  Something else?

I know the Super-V doesn't NEED three servo drivers, but. . . *






* okay, I'm kind of half thinking out loud looking at my pair of coaxes and H600 amps, and it would be a waste to run just two on the amps when they could easily handle three very well. . . **






** . . . and I likes me my bass. . .  :D

Hmmm......

As I have lived with the duals for as long as anyone.....

Perhaps you should audition a set...I have others that will punch your guts....
I prefer these as they are much more musical....realistic, not wrenching.....

You might just want to add an external seperate pair of servo subs.

I sold 4 pairs to a guy in the UK that added another woofer below to make three subs then the coaxial. However, he was using them in clubs, not in a home setting.

And yes, it pushes the coaxial way to high up in the air.

Adding one to the top requires considerable structural changes that would greatly compromise the open baffle space of the coaxial.

For most listening my lower woofers on my Super-V's never even see half of their X-Max. In fact I bet they only see ranges that are above half of their X-Max when I take them to shows.

I'd say that if you need more bass than that just add another pair in a separate box a few feet behind them and a few feet back. You could even play with the location to really smooth out any room issues.

That's awesome!  Did he happen to send any pics?

Sounds like they were painted MDF. Nothing to look at. No pics were sent.

They were also all V-1's (not Super-V's).

Danny, thanks for answering my question. :)

Thinking about it, putting a three servo setup in a club (putting the coax about at head height standing), assuming they were placed well, could both solve a lot of common problems with the sound from club systems as well as give the club a lot of sound horsepower without an overly huge investment in amps.  Very clever solution and it would be cool to check out music at that club.


PDR, Rclark:  Right now I'm running a pair of dual servos in sealed boxes in my rig.  In my room, other than the huge dynamic range in my system, having this much speaker (subwoofer) got me "there" in regards to the impact my system delivers with much of the music I listen to and got the "playing big" part down in regards to some of my other music. 

For example, my system absolutely sings recreating amplified electric guitar - it just sounds "right", and that is being a bit stingy on the volume knob.  It isn't that I'm after 100db + continuously pounding music, but in keeping up with the coaxials, when the lower registers have to hit HARD - even for just a second - and the system delivers so effortlessly it may as well be laughing at the task. . . you get the idea. :)

That said, I'm getting closer to where I want to be with my system overall, and I'm glad to be getting down to the nuts and bolts of tweaking for personal preference rather than trying to zero in on the broad strokes of what I like in how my system goes about its task.  A part of my musings comes from hearing the many glowing reviews of what the open baffle system does for the p-audio drivers, as well as an interest in how this could change how the servos do  their thing - call it curiosity as to whether or not the change would get me closer to my ideal. 

What I don't want to lose in the process (in the bass in particular) is the tactile presence the spl/pressurization in room my system can produce brings to my music (not to mention that my speakers occasionally are tasked at belting out the LFE of an action movie), hence my thoughts on adding "more" to the servo side of the Super-V.  Again, not that duals aren't up to the task MOST of the time (heck, for all I know it could be all the time), but adding together the following:

I've got the "big" servo amps in front of me already,

The extra cone area really isn't TOO expensive, comparatively speaking and all told,

There have been a number folks in this circle have talked about it, but I haven't read much feedback from someone having gone through with actually doing it. . .

. . . and it seems in this hobby I don't seem to mind living a little on the edge. . . :D


Good thoughts all around and thanks again, all!



Another (slightly off-topic) question - anyone with any thoughts on just doing the coax OB and leaving the servos happily in their boxes?  Maybe a good compromise considering what I'm after?
