Plugging in the Polk subwoofer psw303b by the Polk book is very confusing.
Polk's owner’s manual shows the wires coming out of the Receiver carrying an audio signal. Polk's manual tells us clearly that Mr. Polk and his engineers then advise us to put these wires, into the Speaker Level Output of the Subwoofer. Output to Output!
When this was discovered we were setting up a surprise for Christmas and it was to late to take all these Polk speakers back. Now that we have established that Mr. Polk knows what he is doing.
Polk goes on to explain that many Amps do not put out a signal to the Subwoofer in TV mode. The subwoofer signals still go to the Left and Right stereo speakers. It looks like Polk suggests hooking the subwoofer to the LF and RF speakers so that the filter in the Subwoofer can control the low tones.
In order to get this audio signal into the sub, figure 5 shows hooking up the LF and RF speakers to the Speaker Level Output. This diagram clearly shows that the only way a signal can go into this subwoofers input is if the audio signal is coming FROM the speakers. All the time I was supposing that sound was to be coming out of not into the speakers.
If it turns out that maybe somehow the labeling is incorrect. What else is backwards in the designing of Polk's products?
How can the externals be mixed up and the internals in the right position?
Are the labels on the Subwoofer that say Filtered and Unfiltered also reversed??
What are they supposed to indicate? How can we trust anything from Polk if they are using some little known laws of electricity, and Polk does not explain what they are?
Audio test
Ok so I hooked up the RM6700 with PSW303 subwoofer to a Denon avr-1603/683 av surround receiver with Subwoofer (Out) jack.
Before reading the Manuel it was hooked up according to Polk's Figure 7 “Sub Out Hookup.”
After reading the Manuel it was hooked up according to Polk's Figure 6. I did not go to Figure 5 at that time because the wire now running all over the house was not long enough to switch the audio base from the Amp to the Subwoofer.

The Bands “Last Waltz,” rock concert, was on AMC TV (cable) shortly before Christmas. I could not hear much, if anything, coming out of the Polk subwoofer.
As a test, I reconnected the “Monster Sub-out cable to the “Line In (Filtered),” jack on the Subwoofer and made the appropriate changes on the Amps output.
Boom all of a sudden I could hear Sound. Now here is the thing. When I removed the parallel wire hookups, there was no noticeable change. I was getting the sub tones from the sub out Amp outlet when activated. But not getting the tones from the parallel wire hookup when the Amp sub-outlet is deactivated.
I am going into the Subwoofer using a line that is filtered coming out of the Amp. If the labels make any kind of sense. I am going into a jack with a filtered line. Why do the low pass and volume knobs have an effect on the sound?
If I am relying on the Amp to filter the signal, why is the Polk subwoofer still modifying the output from the Amp?
The last modification was to put a splitter on the single sub-out hookup to go into both the L and R Line In (filtered).
Should I be going into the Line In (Unfiltered) port with one wire, instead of splitting the signal into the ports marked Line In (filtered)?
