Seas Excel Bifrost Kit - Pair - Parts Only
 The Seas Excel Bifrost is a top of the line 2-way speaker kit utilizing the T29CF-002 tweeter and W18NX-001 woofer. These drivers represent the highest end offerings from Seas of Norway. Detailed information on this kit design can be found here on the Seas website.
The T29CF-002, known as the “Crescendo”, is the flagship tweeter in the Seas Excel lineup. This Ultra High End 29mm soft dome tweeter employs a wide SONOMEX surround and high efficiency HEXADYM magnet system. Building on the success of the famous “Millennium” tweeter, Seas has once again raised the bar with the “Crescendo”. In addition to world class performance, the Nextel painted machined aluminum face plate with chrome plated brass center ring makes this one of the most visually appealing tweeters we know of.
The W18NX-001 is the 7” paper cone mid/bass woofer of the Seas Excel line. A Nextel coating is applied to the front side of the cone to provide added stiffness, while a special coating is also applied to the rear of the cone to reduce cone resonances. With such features as Adaptive Surround, copper clad aluminum voice coil, and heavy copper rings mounted both above and below the T-shaped pole piece, this driver is defined by its excellent transient response and very low distortion. The chrome plated solid copper phase plug and Nextel coated cone are a perfect cosmetic match to the “Crescendo” tweeter.
We are offering the Bifrost kit with assembled premium crossovers. The low pass circuit uses Goertz Copper Foil 14awg inductors in series with the woofer. The high pass circuit uses a Mundorf Supreme Silver/Oil capacitor in series with the tweeter. This component selection was carefully chosen to best match the drivers and design of this system. High quality resistors, caps and air core inductors are used in the remaining circuits. All Bifrost crossovers come assembled on a Matrix Double circuit board and are bi-wire/bi-amp capable. Alternate series capacitors for the tweeter (high pass) circuit are available on the drop down menu above.
If you are interested in high quality custom cabinets for this design, Madisound would like to recommend Lee Taylor & Co. Contact Lee to discuss veneer options and pricing.
