Was bored the other day so I took the Realistic Mach Ones I have and disconnected the midrange driver. Took the wires from the crossover and connected them to an Altec 808 driver mounted on an EV SM120 horn. Had to turn the bass down as these speakers have a peak around 100 hz. Have to say they sound better and have better imaging than my Magnepan 1.6"s. Driving them with a Dynaco ST70 amp. Room size is about 15' x 20'.
