Well, color me impressed so far! I bought a transmitter and 3 receivers a while back and just started using these today.
Easy setup, just press a couple buttons and walk away. Simple.
The project I started today was to move my subs around to see if improvements could be found. The answer is yes, although that bar was set kinda low. The dual subs, with 1 driver front facing and 1 passive downward facing, were next to each main speaker and they measured sorta ok from their low spec of 24Hz up to 100Hz and then took a dive above that. And yes, I know I could do the crawl, except that I really wanted to do the measuring with Dirac, so . . .
The VSUB system made it really easy to move the subs. Had them on one wall, two walls, aimed one way, aimed two ways, stacked, then . . . wait, what? Yeah, stacked. That seems to work the best right now, and in a location which works well for the room layout. Tomorrow I'll get an old smaller Rel connected with the third receiver and see what happens.
Meanwhile, love the VSUB-1 !

ttocs what cables did you use to connect the modules?

ttocs what cables did you use to connect the modules? From the processor to the transmitter I am using a DIY XLR to RCA cable. For connecting the receivers to each sub I have AudioQuest Chocolate 2-Meter RCA cables I haven't used for a while. Way too long, but they work. My subs only have RCA connections for Line and LFE Inputs, as well as a Neutrik connection for Speaker Level Input. So I am using the LFE Input. |

Should do the trick! They're short, and it's just for bass.

I just received two VSUB-1 Transmitters so now I have 3 Transmitters and 3 Receivers, I wanted total flexibility to do whatever might need to be done.
The first benefit I was almost sure would happen is the Ground Loop Hum that my old Rel is susceptible to is GONE. So it's pretty huge that the subs are now only tied to any grounding through 1 connection, not 2.

ttocs,
any new thoughts or comments on the VSUB-1 units, after 6 months of use?
kicking tires on them.
thanks,
gregg

ttocs, any new thoughts or comments on the VSUB-1 units, after 6 months of use? kicking tires on them. thanks, gregg I'm still using the 3 for my LFE subwoofer group. No problems, but, take note that when unplugging and plugging back in just one receiver, the "connection" can sometimes be "disturbed". This results in the transmitter and/or receiver blinking to say that the connection is lost. This is an intermittent disturbance and happens for a few seconds, then stabilizes. I never though about it much because most of the time it was when the system was off, the VSUBs are left on all the time as they only need a watt or so. But I discovered that the fix is just to power down transmitter and receiver, then power up again. Simple. After a major overhaul of my system, I took the time to renegotiate the connections and they've been stable ever since. There's no issue with timing. I use REW all the time checking things and there's never been a bad measurement caused by one or more subs not communicating or lagging. Simply has never happened. This is a plot of three subs in what I call the LFE Group, which as the name implies, only carries the .1 LFE channel. REW measures the LFE channel with the LFE cutoff in play, hence the rolloff above 80Hz. If there were ever a communication issue it would show up immediately in the plots.  I might get a 4th VSUB pair for the sub that's at the back of the room if I decide to use the Line In for a different usage in addition to the LFE input that's currently being used. So that sub would then have two receivers on it. Also to note, I've NEVER had a pop or thump!!!! |

ttocs,
thank you for that update. sounds like a success.
what advantage are you experiencing with the "pairs" of units vs 1 transmitter and multiple receivers?
you previously mentioned wanting complete flexibility. what is this flexibility, is it multiple LFE channels?
thanks,
gregg

ttocs, thank you for that update. sounds like a success. what advantage are you experiencing with the "pairs" of units vs 1 transmitter and multiple receivers? you previously mentioned wanting complete flexibility. what is this flexibility, is it multiple LFE channels? thanks, gregg The Center Sub output runs to a miniDSP that then sends the signal to the 3 subwoofers for LFE. To make them all work together happily, they each need some unique settings - specifically and probably most important is delay. All of the settings to make these 3 subs work together must be done by the miniDSP because the subs are also working with other subs just for the Left and Right Main speakers. It's complicated. So once the Left/Right pairs of subs were working well, then I got the LFE Group to work well separately. I post my insanity in the thread Finding Subwoofer. Things radically changed from the beginning of the thread to where things are now as shown in the last few pages. I'm close to being able to post some informative findings, but might still be a few weeks for that. If it weren't for the fact that our processors allow LFE to be a separate and unique channel - like it should be - I wouldn't be able to setup the system to the degree of satisfaction I'm experiencing. |

interesting, thank you.
it does sound complicated.
i'll give that thread a read.
