ACG’s 70 Series is a platform accommodating a variety of the latest high-tech drivers in the popular stand mounted mini-monitor format. Experience shows drivers at the present state-of-the-art are held back by typical simple MDF enclosures and cost constrained crossovers. Series 70 addresses that by using higher grade cabinet plywood, constrained layer and limp mass damping techniques. Insuring driver integration is Danny Richie designed crossovers using all polypropylene capacitors and air core inductors. Each pair is built to order allowing extensive options in drivers and crossover components for an exact match to the client’s use case and budget. For those into advanced DIY the Series 70 designs are available as kits including flat pack enclosures ready to glue and finish.

Initial Series 70 monitors use SB Acoustics Satori ® series drivers. Woofers are 5” class drivers options including TeXtreme carbon fiber or Egyptian Papyrus cone material. Tweeters options include domes in Beryllium, or TeXtreme carbon fiber, or two grades of silk. Baffle upgrade option uses precision machined Panzerholz. Panzerholz is bonded beech hardwood veneers using phenolic resin densified by subjecting the panels to high pressure during the manufacturing process. Prototypes comparing plywood to Panzerholz baffles dispelled skeptics’ questions as every aspect of music reproduction improved with the superior mechanical properties of Panzerholz baffles.
