Seas CX871 Coaxial 3-Way Speaker Kit by Peter Noerbaek - Pair


Price shown is for a PAIR

This latest in the highly prized line of speaker kits from PBN Audio is poised to earn major attention within the home electronics community – and rightly so. Featuring two superlative drivers from SEAS, an international leader in high-end sound systems, these elegantly simple yet aesthetically refined speakers define the most basic premise of stereophonic excellence: It’s all about what you hear. PBN Audio has devoted decades of engineering prowess to designing systems that completely serve the music. The CX871 delivers on that promise.

The SEAS Drivers 

Midrange and high frequencies are married in the MR18REX/XF (H1699) 7” Midrange Coaxial Loudspeaker (top), with a pre-coated reed-paper cone. The cone acts as a horn loading for the tweeter in this efficiently compact driver, providing superbly balanced sound. The coax ensures a level of stereo imaging that simply cannot be obtained in other ways. 

Bass duty is anchored by the L22RN4X/P (H1208) 8” Aluminum Cone Woofer. It features a 4-layer, high-temperature voice coil. It is a driver with an extremely “stiff” cone offering great bass precision, plenty of power handling, and impressive low-frequency extension. Two units per speaker works well to mate with the coax midrange.

Design Prowess 

PBN has dedicated years of engineering to support the technology of this kit, which uses advanced electronics to achieve the best possible results. Peter is known for his advanced crossovers, which ensure that the drivers blend perfectly together. There is no compromise on the crossover design or components. With this approach, you can expect an outstanding sound stage (width, depth and height), cohesive blend, and pinpoint imaging. The system works well for both home hi-fi and precision studio monitor applications. We are confident the quality is so good, this could be your final system.

Assembled Crossover Information

Madisound hand assembles each crossover to order. We use premium parts throughout to compliment these high end drivers. All parts are terminated with 3% silver solder to our silver tinned copper circuit boards.

The series tweeter and midrange circuit use ClarityCap CSA line. Mundorf EVO-Oil caps are available as an altenative for the tweeter caps. They are too large to fit on the midrange board. 

The series woofer circuit utilizes Solen Perfect Lay 14 awg inductors. 

Crossovers are available for seperate purchase from the drop down menu.
