There are different power classes for Bluetooth. The article here
claims "100 meters" with Class 1. So I'd check the "Class" of both
the Bluetooth transmitter and the Bluetooth speakers.
http://en.wikipedia.org/wiki/Bluetooth
"In most cases the effective range of class 2 devices is extended if they
connect to a class 1 transceiver, compared to a pure class 2 network."
I don't know if I believe that. If both devices were class 1, then there
would be a better chance of getting the extended range. Mixing a class 1
transmitter, with class 2 speakers, may still only give the 10 meter range.
The performance of the product, may also depend on the wireless environment
it is used in. For example, if you already have WiFi N equipment, cordless
telephones at 2.4GHz, microwave oven, and all sorts of other wireless
gadgets, the Bluetooth communications may have trouble punching through
all of that. If the Bluetooth link cannot deliver the required bit rate
for the SBC codec, then I expect there will be dropouts in the music.
I suppose you could run a USB cable closer to the other room, and plug a
Bluetooth dongle into that. Or position a powered USB hub at the
end of the USB cable, to ensure a good power source for the Bluetooth
transmitter. That would allow some optimization of antenna position, like
get closer to a doorway for line-of-sight.

If the computer is a laptop, then that wouldn't be very convenient.
If the computer is a desktop, then a few more wires might not be so bad.
