Chris Pelonis Signature Model 42 MKII
The Model 42 MK II continues the tradition of quality of the original TEC Award nominated and award- winning Model 42. Based upon the industry’s finest dual concentric driver, the MKII’s rhomboid shaped enclosure and DSP assisted amplifier deliver unique performance and functionality.
Why upgrade an award winning speaker? The reason for the upgrade is all about headroom. At Pelonis Sound our philosophy about headroom is “the more, the better”. Every piece of equipment in the signal chain should “clip” at the same level. Setting the calibration levels within a system is essential, but many active loudspeakers are designed with inputs that are “hot”, so they seem stand up well in dealer’s showrooms. Few pre-amps have room to “breath” when driving hot speakers. Not so with the Pelonis Signature Series. Pre-amps run at or near their “2 o’clock” unity gain settings.
While this is an ideal situation, few dealers take the time to explain the advantages of a full system calibration, where headroom is maintained end to end. Many people just assume that LOUDER is BETTER. Well, we couldn’t agree to give up headroom, but given the perception the Signature Series needed more gain, we added 3.9dB to the inputs and even picked up a dB of headroom in the process!
Chris doesn’t believe sensitive electronics belong in a vibrating, magnetized enclosure or that power cords should be near audio cabling, so individual 100W amps for each driver and precisely tuned active crossovers are housed in a sleek external unit.
The rhomboid shape of the loudspeaker enclosure and the utilization of “Point Source”, Coaxial”, Dual Concentric”, and/or “Single Driver” loudspeaker driver technologies create a unique performance and functionality to this design.

With regard to the driver technology. By positioning the “High Frequency” driver in the center of the larger “Low Frequency” driver( Coaxial, Point Source or Dual Concentric), the distance from the source of high frequencies and low frequencies is consistent regardless of the position of the listener/receiver in relationship to the loudspeaker. This results in consistent time arrival of the entire frequency spectrum produced by the combination of the high frequency driver and the low frequency driver. By keeping the time arrival constant, the frequency response and phase response of the speaker will not be degraded as a result of position of listener/receiver to speaker. In the case of a “Single Driver” where one driver delivers all frequencies, the same holds true. The natural off axis characteristics of the driver or drivers combined will be consistent regardless of polar off axis positioning of the listener/receiver to the speaker.
