It would be nice to see the back of the unit, so we could see what kind of input(s) / output(s) this thing has. Even if they were listed in the spec’s, that would be helpful.

Best Buy has the picture

Hows this?

Doesn’t look like the back of my Polk Audio SW. At least I can run standard speaker wire to it and it had outputs to L/R speakers too. Paid about 99 bucks at ABC Warehouse. It’s the PSW10

The title states that it is 100W but the specs show 200W. Which one is it?

Specs state 200W peak and 100W RMS.

Go with the 100w as continuus power, 200rms only for bursts of power. Like a generator. It’s rated at 8k watts but startup power is 10k.

But I did find this LONG drawn out example of how it might apply:

Many people confuse these specifications, so I will try to give you a simplified, non-technical explanation. Continuous RMS Power, is the spec that really tells you how powerful an amplifier is. RMS power is expressed in watts. A typical specification might read 100 watts RMS into 8 ohms from 20Hz-20KHz at .01% THD. What this means, basically, is that the amplifier will deliver 100 watts into an 8-ohm speaker from 20Hz to 20Khz? This frequency range is basically the entire audio range that an individual can hear. The THD spec stands for Total Harmonic Distortion: This is the amount of distortion the amplifier will introduce into the original signal. Any high quality amp made today has extremely low distortion ratings. The human ear cannot hear anything under 2%. For the most part, when you are considering purchasing an amplifier, you can disregard the THD specifications. Dynamic Power, is a little more difficult to understand. This is a test of the amplifier’s ability to go beyond its continuous RMS power for a very short time period. We are not talking minutes or even seconds here. We are talking milliseconds or thousandths of a second. A musical transient peak, such as a cymbal crash lasts only a very short time. Dynamic power is usually measured into 8 ohms, but specifications are generally also published for 2, 4, and 6 ohm loads as well. To keep things from getting too complicated, we will concentrate on the 8-ohm figures. To measure dynamic power, an amplifier is fed a 1000 Hz signal for 20 milliseconds then allowed to rest for 480 milliseconds. The amplifier volume control is turned up until the amp reaches the clipping point. At that point, the amp has reached its instantaneous peak or dynamic power output. Like the continuous power rating, dynamic power is expressed in watts. The figure is usually significantly larger than the RMS power rating, and should not be confused with the continuous power ratings of the amplifier. A dynamic power rating into a figure such as 1 or 2 ohms does not mean that the amplifier can drive a speaker with a 1 or 2 ohm rating continuously. If you attempt that, the amplifier will either go into the protection mode or possibly cause damage.

Oh, and its at the mothership for 99 bucks too (the Polk Audio that is).

Very helpful. Thank you.

That’s not the same model at all - not even the same brand.

This one’s closer:

oops, my bad… I had JBL on the brain but had mentioned the POLK AUDIO. Thought it was obvious but I corrected it just the same. Thanks

But I think it’s clear, one on one, the Polk Audio has more features.
