The X's were very...polite loudspeakers. The cabinets resonated and the Masonite back was worse than silly. We all tossed them. The + series was the big breakthrough 2+2, 3+3 and 4+4. I wish I had 3+3's but very few of them were made. Right now I have 2+2s and an ornate subwoofer system crossed over at 125 Hz. IMHO the only speakers that are better are the line source Sound Labs. I am chomping on the bit to get a set of Ultimate 845s. If you can get a set of clean 2+2s and can afford to add subs you will be seriously pleased. Taken care of Acoustats are immortal.
Unfortunately they became very inexpensive and most of them were mutilated by experimentation. The panels outside of their frames can be easily cracked if mishandled. Never buy loose Acoustat panels. The vast majority of them are damaged.
