Hi Folks,
I have a
new AVR-891, but was hoping to use my
old Polk Audio RM6200 speakers with its modest, included
PSW250 subwoofer in a configuration that allows the Denon receiver to control its crossover, output, etc.
Unfortunately, this older, amplified subwoofer appears to offer no unfiltered/LFE inputs - only speaker I/O connectors and Line Level In (L/R).
I'd prefer to have the AVR-891 be my center of control for all speaker levels, so wanted to eschew the use of speaker I/O connectors with the subwoofer. However, on the possibility of using Line In, two configuration options seem to point towards essentially keeping the subwoofer invisible to my Denon receiver:

OPTION #2
This method can be used with electronics that include a “SUB OUT” feature (Figure 4, previous page). It is not recommended for use with RM6200 or RM6600 Systems. Connect a single RCA cable from the “SUB OUT” of your electronics to the LFE input of the subwoofer. This input bypasses the subwoofer’s variable low pass filter and relies on the filter built into your electronics. If your “SUB OUT” is an unfiltered signal (check your owner’s manual), use either left or right “Line Level Input,” to use the low pass crossover in the subwoofer.
When using option #2, it is necessary to adjust the settings of your electronics as follows: Front speakers = large or small depending on their output capabilities; Subwoofer = “ON”.

OPTION #3
This method is for use with electronics featuring a “PRE OUT” – and may be used as a secondary hook up method for use with RM6200 or RM6600 Systems. Connect the left and right preamp output from your electronics to the left and right LINE LEVEL input of the subwoofer. This may require use of RCA “Y” cables (not supplied) to hookup both the subwoofer and your electronics (PSW250, PSW350, PSW450).
When using option #3, it is necessary to adjust the settings on your electronics as follows: Front speakers = LARGE Subwoofer = “OFF” or “NO”.
The RM6200 speaker documentation offers the following:
Quote:
" Line level inputs can be used when you run theLeft and Right Preamp outputs from you receiver or preamp to the subwoofer’s line inputs.
These are filtered inputs and require a full range output from your electronics to operate correctly.
"The subwoofer (LFE) output from your receiver is not recommended for use with the RM6200 system. The filter characteristics may not offer satisfactory blending.
Even though the subwoofer documentation seems to indicate that I should use a speaker I/O hookup or Option 3 (above), I was trying to determine if Option 2 might be reasonable. It seems that the final quote above takes Option 2 out of the running, but was curious about opinions from those here who have more experience in this matter than I.
I guess that my fallback considerations are to configure the subwoofer independent of the Denon or obtain a new powered sub which accepts LFE input.
Thoughts welcome.
Thanks,
