Floor Standing Speakers to Monitors and Subwoofer

Ooops, and of course the Boxers! They'd be a great anchor for a 2.1 or 2.2 system because they have higher sensitivity (90 dB) than most mini's with their higher handling capacity and of course are well-known for an endearing sound that draws you into the music. The high sensitivity and power handling mean setup should be easier and less dependent on a high pass filter to get good integration and dynamics.

You can't 'upgrade' from the Lsi-15s for 2000 dollars. You can get a different pair of speakers for 2000 dollars. I own them and play them is a similar sized room. Some times we just have to accept that we did it right the first time. Get 2000 dollars worth of CDs instead.
Cheers.

How about getting the LSi/9's and a sub or two? The LSi/9 has the same mid/tweet arrangement as the LSi/15 and they're only $599/pair through Amazon.. Then you can get one or two subs to blend and adjust the bass output to the smaller room. Rok2id has a good point. I haven't heard the Polk LSi line myself, but the LSi/9 appears to be a bargain for a pair of MTM monitors with ring radiator tweeters for $599.

Johnny how does the PM1 fare without a sub?
