I'm copying this from the Yahoo Group list because someone recently asked a
similar question.

Before you give up on the 1.8k filter, be sure to try the following:
1. Tune in a station exactly using a wide filter.
2. Adjust WIDTH = 1800 (or less).
3. Adjust either SHIFT (my preference) or HI/LO CUT for best audio.
With proper adjustment you can get good intelligibility down to 1500
Hz. I believe my SHIFT setting is ~200 at ~1800 BW and goes up to
~400 at ~1500 BW, but let your own ears be your guide.
I learned this back in my FT-1000MP days and it's absolutely
necessary for using any rig at low bandwidths on SSB.
I would only recommend a 1.8k for someone interested in contesting or
perhaps DX-ing on the low bands. Unless you have extremely strong
stations nearby, the standard 2.7k will still work fine and you can
always narrow the DSP filter to <1800 when necessary.
