Note off axis response is extraordinary compared to the vast majority of systems. Combined with the ultra-low resonance characteristic of this design, this system has the potential to exceed the realistic perceived reproduction capability of the vast majority of monopolar speaker systems, regardless of cost.
In addition to the above properties, this system also has substantial dynamic range capability as a result of the JL Audio W7 low frequency drivers and 2 x 6.5" midbass drivers operating from 100Hz-450Hz in each cabinet, thus concentrating substantial linear displacement capability for the spectrum of music that has the highest ratio of energy. In addition, this is a fully active system, with an individual amplifier channel dedicated to each speaker band. 250 watts to each tweeter, 250 watts to each mid-range, 350 watts to each mid-bass cluster and 450 watts to each woofer. These power ratings are based on the 20Hz-20,000Hz full band power response of each amplifier(1Khz rating is much higher). This gives a total of 2600 watts to the system, or 1300 watts per stereo channel, making this system virtually un-clippable and ready to handle playback of virtually any recording with ease.
For those not up to date on this project: this project was originally contracted by Matt34. Through reasons not relevant to this thread, the speaker was sold twice, eventulaly ending up on Jerry Love's possession. The original contractee specified the veneer type/finish and the specification to retain the original Primus's front baffle color/design.
The speaker is a Primus in historical representation only. Modifications are so radical that this is a completely new speaker design/system that converts what was originally a budget speaker into a high end performance monopolar speaker system that will compete with ANY price range of speaker system.
