I bought a Home Theater System with Blue Tooth $99.95. 4 speakers are each 3" square. Woofer sound bar has 2 speakers 2" diameter each. Wires to speakers are #26 wire. Wire are so small they will not stay in the wire clamps they keep slipping out. With sound turned up TV is 2 times louder than the sound system but the sound coming from the sound system sounds better quality. I told wife leave sound system volume all the way up then use TV remote to change the volume, turn volume up to 50 instead of 25. The 8" x 10" x 12" large box with a volume control makes the whole system look, more better, less worser, more gooder, it will fool stupid people. LOL. I bet there is nothing inside that big black box just a volume control for the 6 speakers. I bet the whole sound system is powered by the TV amplifier. No technical information on the box or instructions at all. I am surprised the box does not say, 200 nanowatts to make it sound powerful. LOL. Oh well........wife likes it better than the other speakers that buzzed I guess that is all the matters.
