I have used 2+2's for three years and 1+1's for a few years a while back, and other ESL's for another 20 years. Whether subs will be needed/wanted will depend on the room, the position in the room, the listening level, and (more important than with most speakers,) the amplifier used. Acoustats must sit solidly on the floor! Do not sit them on carpet unless you have some sort of carpet penetrating spike or tiptoes.
I agree that heavy grill cloth muffles the sound, but thin modern knit fabric is easily obtained and installed and does not appreciably affect the sound (according to Soundlabs).
I use a pair of subs on some recordings but prefer them "naked" with most chamber or folk music. On large scale orchestral or rock, the tactile foundation in the bass is simply missing with any ESL I have ever used (or heard), so I supplement the bass from 55HZ down, but use the 2+2 full range.
All said, I prefer the tall skinny 2+2 in my moderate size room, to larger, fatter, shorter, heaver, more expensive designs.
