Yes, I have a Bergantino IP310 and an IP112ER/HT112ER stack. The IP series powered cabinets use a DSP to tailor the poweramp to the driver/cabinet characteristics. Excellent cabs, with the obvious benefit of being able to be matched with any preamp of choice. The 112s are about 50 lbs each. The 310 is 86 lbs. It is quite compact and comes on castors so I've found it more reasonable to move around than you might expect. Although it was discontinued in about 2010, the IP series is still held in high regard today. The B|Amp also takes the DSP approach but puts the DSP and poweramp in the head rather than the cabinet. So one approach provides high flexibility wrt preamp, and the other provides high flexibility wrt cabinet choice. Buying from Bergantino is like eating at your favorite restaurant, everything on the menu is excellent - what you choose depends on your personal preferences and what you're pairing it with. Bon Appetit!
