Adding a sub woofer?


Running a Planar 6 to Icon Audio Ps1 Mk2 to Quicksilver Mid Monos into Klipsch RP8000F speakers. Want more low end, thinking of adding a sub. The mono blocks don't have a dedicated sub output so I was thinking about something like a PSB 250 which has both pre amp and speaker level inputs with speaker level outputs. A couple of questions.

What are the pros and cons of using the sub's preamp level inputs vs the speaker level inputs in this application?

And more importantly, right now my setup is pretty much tube analogue the whole way (and aside from the soft low end, I absolutely love the overall sound) - but does an inline sub like this do any processing, will it color the mids and highs in some way or is it just a clean pass-through in terms of sending the signal along to the speakers? 

Thanks for sharing your thoughts.

I own a pair of REL S2 SHO subwoofers.  What I like about them is their high level connection as well as their home theater connection for sound effects when watching movies.  I am glad I listened to the dealer because two rather than one.

Their high level connection allows the to ack more like woofers than subwoofers to extend the bass seamlessly.  The key is to make sure you set the volume so they don't stand out.  I set mine at 40% volume.  Otherwise, they sound boomy and they disguise the towers.  When you dial them in, they take some weight off the main speakers and allow the mid tones to play clearer.  Be curious to hear what volume level they se their REL's.

Be sure to not buy too small a size.  Buying too small will cause you to overplay the subwoofer and it becomes boomy.  I was going to go with a pair of REL T9's but decided to go with the S2 SHO's.  Glad I spent the extra money.
