ButtKicker BKA300 Wireless Home Theater Kit with ButtKicker Advance and Power Amplifier Review

Average Reviews:

(More customer reviews)I purchased the ButtKicker BKA300 based on prior reviews here. This is my first time owning one of these systems. The intended purpose of was for more immersive movie-watching and playing on a PS3. The kit was setup with a HDTV using the line out on the TV using a Y-adapter to split between it and a 2.1 (two satellites one sub) speaker set. The rumble unit was setup under one of the four rear legs of a three-person sofa.
Watching live concert music on the Palladia channel really gives the feeling of being there. I started noticing that on regular TV programming one can hear muffled sound on most dialog as if the sofa was the speaker. This is a bit distracting, and an annoyance that could be addressed by sound proofing the furniture a bit.
The blu-ray version of The Dark Knight has some loud low frequency passages that causes a loud metallic thump. At first I though it was bouncing against the furniture or floor, so I took a couple of mouse pads as a quick fix test and put them in between the floor and another between the rumble platform and the sofa, but it did not fix the problem. I then watched Pirates of the Caribbean, again on blu-ray, fortunately not much of an issue here.
Gaming on the PS3 was another issue. Playing Call of Duty 4 with the rumble kit really brings gaming to a whole new level. Unfortunately, once I went online, grabbed a sniper rifle and aimed at someone, every heart beat the game produces started causing the metallic thump. I had someone else play while I tried troubleshooting the problem and noticed it was coming from inside the rumble module as if it was bottoming out. A few days later a family member was playing Resistance 2 and the module was not working. It had stopped working within an hour of playing, and was very hot to the touch. Once it cooled it worked again so it appears that it disables to prevent damage. I tried multiple settings for several days, lowering the "volume" on the amplifier, selecting different modes (music,movie,game,) but was not able to fix the problem.
Ultimately, I decided to return the unit. Really disappointing, I recently learned from reviews of the bigger brother (400 watts min, 1100 watts max) unit also bottoms out; this one is 50 watts. I may still give it a cautious try.

KEF Universal Wireless System (Black) Review

Average Reviews:

(More customer reviews)The technical specs on these are already available all over the place, so I won't repeat them here. Instead, I'll give a pro and con review:
Pro:
1) Size - There are three units and each is small enough not to be a big problem to hide.
2) Set up - There is really not much to do. I was up and running in under 10 minutes. The main part attaches to your receiver speaker terminals and an AC plug. The other ends attach to each speaker and to an AC adapter (each needs its own AC plug - three in all).
3) Audio quality - Both a plus and a minus. When it works, the audio is very clear and does not really sound any different than a wired system would. HOWEVER, see my comment under the con section.
Con:
1) Interference - My baby monitor interfears with this system. I know it says it does some fancy type of frequency jumping, but the Garco monitor creates interference if it is too close to the speaker ends of the system.
2) Audio quality - This is a high end (and very expensive) system. It figures that those purchasing it will have equally high end systems. Remember how much you paid for those high end amps? None of that power is used to power the remote speakers. Instead you have an overtaxed 50 watt (I think) amp on the speaker end. For 90% of surround applications this is probably fine, but real audio nerds will not be happy with the result. Of course, would an audio nerd really ever use a wireless system? The lack of amplifier power is even more apparent if you try to use this to power a second set of main speakers. Using a McIntosh amp and mid-range Boston Acoustics speakers (VS240) the clipping was evident.
3) Wires - It should be obvious that a trully wireless system is really impossible. Each unit has a speaker wire hook-up and a dedicated AC adapter (although they aren't the massive brick type.)
4) Auto power? - Just a note that these are always on. It would be nice if they could sense a signal and turn themselves on and off (standby). I have no idea how much power these draw when off, but I imagine it isn't much.
5) Price - At the price point these are placed, I'm just not sure they really are worth it. For the same amount of money (or less) you could probably have an electrician fish some speaker wires for you.

(More customer reviews)I was nearly unable to get wireless in my den, about 30 feet from my office - but through 5 or 6 interior walls.
Added this amp to my router - now get good to very good signal strength where I need it.
Was hoping for "great", gave 4 stars for "very good".
