Has anyone had any experience with this wireless kit?
I'm setting up a 2.1 system in my family room and if this kit works it would make it a lot easier for me to place the sub. For $60 it seems too good to be true!

I have 2 and they work excellent. The do not filter out low frequencies at all. I still get solid extension into the 15hz range with them.

It looks like it will work with most any sub?

basshead81,

Do you know how much delay this wireless unit have? I was looking on the specifications and I they do not mention anything about delay. For sure it has delay but I need to know how much is it. Easy way is looking at the distance that Audyssey set on your subwoofer. If the subwoofer is physically at 9 ft from listening position and Audyssey set the distance at 24 ft, then the delay in the wireless unit is around 15 ms.

This unit from same manufacture have 15-20 ms transmission delay:

The transmission aspect will have minimal added delay. But the device is probably similar to other wireless devices in that it'll encode the signal to digital before transmission, then decode it back to analog at the receiver. That will add delay. My Outlaw Audio wireless transmitter seems to add 15 - 20 feet of "delay" over the physical distance (estimated; as I don't have the before-wireless measurements).

there is quite a bit of delay, I believe ypao sets my distance without wireless at 17ft, with with the rocket fish 50ft. however after they are properly calibrated I can not tell a difference between the subs being wired or wireless. Why is the amount of delay relevant when it can be corrected?

Onkyo AVRs have limit on the distance that you can set of 30 ft, so if your listening position is 10 ft away from the subwoofer and the wireless unit add 30 ms, then the subwoofer will work out of phase.

Subwoofers always work out of phase at some frequencies. There's no such thing as uniform phase response with cone transducers. The pertinent question is whether or not you can hear it. In this case so long as the subs are not 180 degrees out of phase relative to the mains in the overlap zone near the crossover frequency at the listening position you can't hear it. The amount of correction required to insure that can be realized with even a simple polarity switch. If the AVR lacks the ability to provide precise time align that's only a problem if you're able to hear the effect of the delay. In the midrange around 500Hz you can clearly hear as little as 2ms. Below 80Hz you can't hear as much as 50ms.

They have quite a bit - how much I'm not sure but enough so my Denon 1713 (and previous Onkyo 606) distance settings pegged out during Audyssey calibration. IE - the receiver was not fully able to compensate for the delay due to the distance limits it sets relative to the front speakers.

I ended up hard-wiring my sub. That being said - if I had a receiver that didn't set distance limits I would not hesitate to use the wireless adapter.

As far as the Rocketfish goes, what are the limitations for hookup? Meaning, do the sub and receiver need any special input/output jacks? Will this device work on older model receivers and subs?

nope plug and play with standard rca connections...if you read above some recievers do not have enough adjustment in the sub distance setting to correctly phase align the sub with the mains. As Bill F mentions it may not be a big deal tho. Also if your avr is older, it may not have correction software anyway, so just use the phase control on the back of the sub to get it close.

edit I see you have a yamaha, you should be good to go. my 773 has up to 70ft adjustment.

Yeah, I have a RX-V1065. I already have a system set up. I'm inquiring about this for a second system that I'd like to start up. I haven't purchased anything yet, I'm just trying to get info. It all depends whether I think it's worth refoaming an old pair of Boston Acoustics A60's. So I'd like to go cheaper on the new system, than on my current system. Figure I'd find used older gear, but I'd like a universal wireless kit for whatever sub and receiver I get.

The current system I have cost me a good amount, but I don't want to waste the A60's if I can fix them.

Has anyone had an issue with the Rocketfish WSW-312 turning on from standby mode? I have tried two new sets, on two different AVRs and after the WSW-312s go to into standby mode they don't 'wake-up' on unless I re-plug in the LFE. After that it works fine until the AVR is turned off.

I have 2 of the Rocketfish, both turned on pretty instantly with my dual Polk psw505's. However, my Outlaw lfm-1 EX arrived yesterday and from limited time playing with it, it wasn't turning on from standby mode. The light on the Rocketfish changes to blue, indicating it's on, but the Outlaw stays on standby. I'll troubleshoot some more in the next couple days when I get a chance. I didn't want to pay $150 for the Outlaw OAW3 if I didn't have to (but will if that's the only way to get the EX to turn on from standby).

Delays associated with wireless links will occur in the processing that translates the signals from wire to wireless and back again. Depending on the approach used, this can be anywhere from very little to very much.

A good example is your cell phone. It sends your voice which starts off on a wire from the microphone over the air to a base station. The delay can be very long and very noticeable.

Try calling someone else from cell phone to cell phone when you are both in the same room and then try to hold a conversation while standing several feet away from each other. You may find it rather amusing.smile.gif

I saw Dayton has a wireless unit out too. Is there any major difference between these? I've seen ML, Rocketfish, and Dayton.

I just bought the Rocketfish wireless subwoofer kit and the wireless rear speaker kit. The rear speaker kit is working great but the wireless sub will not stay connected. They are only about 10 feet from each other but it just keeps losing signal. 

 

Please help I am about to return the wireless unit and buy a really long sub cable.

I have this kit and I cannot recommend it enough for what it costs. To my ears I hear no difference from using this kit or the sub being wired.

Receiver - Denon 1713
Speakers - Infinity P363's, PC351, P153's
Subs - Rythmik FV15HP's

I recently bought one and had a little trouble as well when I didn't have good line of sight between the transmitter and the receiver. Once I made sure they could see each other I haven't had any trouble. Do you have a clear path between the units?

I really like my sub being wireless. The only thing I don't like is that it goes to sleep after 5 minutes with no signal. I wish it was more like 20-30 minutes before it turned itself off.

There's nothing to see here.

Mine are still working great after almost a year. Just want to add if you have a transmitter not turning on, you need to press and hold the button on the back until the blue light blinks, then release...the device should find and connect to the other transmitter and you are golden.
