The Affordable Accuracy Plus Quick Kit

We are pleased to announce the return of the Affordable Accuracy "Plus" Monitor in an easy-to-assemble "Quick Kit."  The AA+ is based on the Parts Express BR-1 kit and uses the same cabinets and the excellent Parts Express 6.5" Classic woofer. We have upgraded the tweeter to a premium silk dome driver from Morel.  You can see details about the Morel tweeter here.  The robust silk dome tweeter is crossed at a very low 1900 Hz, which provides exceptionally broad dispersion and maximizes detail in the lower treble and upper midrange.  A new complex 14-element crossover assures seamless integration between the tweeter and woofer.

The AA+ is priced at $350/pair plus shipping.  In order to offer a speaker of this quality at an affordable price, we have reduced labor costs to a minimum by leaving the final assembly to the owner.  The AA+ Quick Kit consists of two finished and routed cabinets with integral terminal cups and pre-drilled screw holes, the drivers, fully assembled and wired crossover boards, Eco Core sound treatment pads, and mounting hardware.  You simply snap the crossover wires onto the input and driver terminals, slip in the crossover boards and Eco-Core, and screw in the drivers.  No soldering or cabinet construction is involved.  If you own a Phillips screw driver, you can build a Quick Kit.  Read the full instructions here.

We are not aware of any speaker in this price range that can provide the deep bass response of the AA+.  Although we have specified the bass reach very conservatively at a -3 dB point of 48 Hz, the unique Extended Bass Shelf box tuning allows the monitors to produce very audible output at 34 Hz.  You can test that for yourself with a demo CD that we include with every kit.  The result is a firm bass foundation and very high power handling on music material without the cost and complexity of a subwoofer.  If you wish to order or have questions, just write to us at info@philharmonicaudio.com
