Customer Reviews

BK-Link works with subwoofers as advertised
I have to add my .02 cents here. First of all, the rambling review quoting transducer frequencies is wrong. He did give the unit 5 stars, however he tries to defend the unit by attempting to invalidate the reviews of the unit when used with a subwoofer rather than the BK shakers.

Guitammer clearly states this unit can be used with a standard subwoofer which is specifically what I needed it for. I read the reviews here and decided to keep looking but after a fair amount of research, I found no other devices claiming the (sonic) frequency range of the BK-Link. Other wireless units were offered in sets and were intended for use with rear surrounds. Along with being more expensive, they also claim 20Hz to 20KHz audio which is standard speaker range. It's also the range of human hearing (generally) but subs are also about feeling. Both of my subs go well below 20Hz and I wanted to be sure I would get all of the performance out of them that they are capable of giving.
The operating frequencies of the BK-Link unit start at 5Hz. The upper range is stated to be 350Hz. Much higher than anyone should need for the intended uses.
So... I went ahead and got this and figured I could return it if it was unacceptable.
I was prepared to chase down any hum, something I'm quite experienced at. But, there was no hum to chase. I plugged it in, hooked it up, and it worked.
I played one of my favorite sub tests, the crash sequence from "Flight of the Phoenix(2005)", as I am very familiar with my sub's performance with this material and I see, or should I say hear, no difference between a line and the BK-Link.
No discernible delay was added nor was any loss of volume or tone obvious. This held true for music tracks also.
Testing for speed and accuracy, I reached for "Fade to black" which has a prolonged rapid double bass kick at the end that will trip up inferior subs even with direct connection. Again, no difference with the BK-Link compared to a direct line.

The send unit sends, the receiver receives, the woofer woofs. End of story. It also does so out of sight and out of mind. Which it should.

I realize hum is a genuine issue in a lot of systems. I also know it can almost always be remedied. My $5K component pre/pro and amp had their share of (humming) gremlins when added to my somewhat extensive HT setup and that's with balanced interconnects. After working through my system, I resolved all issues one-by-one.

After seeing and now using the BK-Link, I think it is no exception. Although my system is already quite settled, the BK-Link brought no NEW issues to the party. Meaning, most likely, if you're having issues, it's with a system that was already prone to have issues. You may run into problems adding ANY new device to your system. You just need to do some homework and you will, with very few exceptions, be able to work it out. An added bonus is, you just may find your system sounds better after resolving your newly found latent electrical issues.
P.S. Audio (dot com) has a great essay on hum busting on their website. It is really a great piece with lots of great ideas for fixing these issues. Perhaps if some who've reviewed this item poorly happen to read this, they can take another shot at it armed with a little more information.
If you're having a problem with the BK-Link, I wouldn't be so quick to blame the unit. ALL HT components are susceptible to some extent. The BK-Link is no different.
As my Mama always said, "don't throw out the baby with the bath water".

The BK-Link DOES work with Subwoofers. It works as well as I could possibly have hoped and I am extremely pleased with it.

Works great for my subwoofer...
After reading the reviews and searching the web for reviewers saying that this could work/couldn't work for subwoofers other than the Buttkicker, I'd thought I'd give it a try, not wanting to run 40-some odd feet of subwoofer cable. Seems to be working fine with my Definitive Technologies powered subwoofer, and I'm not hearing any noise or outside signals/interference. I don't have any wireless units using the same frequency and I'm using it in a single home, so that might be a factor. I have the transmitter pointing out from the front of my entertainment console, directed at the receiver unit (which I have on the floor under the nonsofa bed couch), which is about 15 feet away. I tried having the receiver sitting on top of the sub behind the couch, and that worked fine as well. The only downsides I see currently is that all the units have power running to them so they're always sucking juice, and if you have the transmitter in view, the bright green LED could be distracting; otherwise, it does just what I wanted it to do.

Great Product, up and running in 5 minutes.
These other reviewers must have received defective units.

I bought these wireless Buttkicker [trans-receive] units new and installed them in about 5 minutes.

NOTE: I am using them with bass-transducers connected to a LFE enabled AMP; I am NOT using subwoofers.

I am not sure if this makes a difference, but they work perfectly with my bass-transducers and I am very happy with them.

If you read all the negative reviews about these units online, you may notice a trend, which is that all of these people tried using these wireless units with SUB-woofers.
