This speaker does everything!
I am a professional magician and hypnotist who has been searching for the perfect sound system for my show for over 5 years. When I first read about this speaker, I was very intrigued. I purchased one of the first U.S. arrivals and I must say that after using it in a dozen shows, I am very pleased!
First of all, the sound is awesome! I am not a tech guy, but I can tell you that it has plenty of power and a nice deep bass. The 3 EQ controls are very nice to fine tune the sound. The 1000W is definitely powerful enough to fill a room of 250+ as I have done 5 times already. The real magic is in the versatility of the unit. One of the features that I was looking forward to using is the Bluetooth connectivity. I use my laptop computer to play music during my show. Sometimes, it is difficult to connect the laptop to the PA system and still be able to access the keyboard from the stage. With the B115W and a $15 Bluetooth transmitter that plugs into my computer, my problem has been solved. Now, I can have my computer anywhere (within 30' according to the specs) and not have to worry about cables! The sound is very good with just a few minor dropouts in over 8 hours of performance. Pairing the unit with my computer was very easy and once learned, the speaker has remembered my settings. This feature has cut way down on my set up time before shows!
The next accessory I purchased was Behringer's ULM100 wireless microphone that is designed to work with the B115W. For $100, the microphone is certainly affordable. However, I have noticed that the sensitivity is not nearly as good as when using my Line 6 rig. Also, when using a wireless music source (computer or mp3 player) and the ULM100 simultaneously, the range on both is diminished. The user manual even warns about this. Therefore, I plan to use the ULM100 only as an emergency backup since it is very easy to pack because of the small USB receiver that is the size of a standard flash drive and since no cables or power supply is required.
For larger shows, I plan to purchase a second unit and use the Bluetooth wireless connectivity to eliminate having to pack speaker cables. Currently, I have been using a Behringer monitor connected to the line out and it has worked perfectly.
For the money, the B115W is a real powerhouse!!! Thanks Sweetwater!
