Double treated, hard paper cone designed to be very stiff without losing the damping capability, together with a natural rubber surround produce a well behaved roll off characteristic and reduce potential resonance problems.

Large magnet system with bumped back plate together with a long 4-layer voice coil gives long linear excursion. The magnet system has a T-shaped cross section of the pole piece for low modulation distortion.

Extremely stiff and stable injection moulded metal basket keeps the critical components in perfect alignment. Large windows in the basket both above and below the spider reduce sound refl exion, air flow noise and cavity resonances.

Having already cemented himself into DIY speaker building lore with comprehensive driver testing and review, as well as many highly regarded (and very well documented) designs and kits..... Zaph is at it again.

Madisound is pleased to introduce a new driver to our lineup, the Zaph Audio ZA14W08 5" Mid/Woofer.

We are confident that you will see what we do in this highly attractive driver that hits the sweet spot in both performance and price.

Please stay tuned for a full line of kits based around the exciting new Zaph 5" Aluminum Cone Mid/Woofer!
 

• ø145mm large ferrite magnet and 8mm top plate are employed. Besides, the copper cap is adapted onto the pole piece to reduce the magnetostriction.
• HR shape cone diaphragm is employed to realize the weight saving and stiffness property.
• The state-of-the-art hybrid material is offered to the diaphragm. Its ideal internal loss and stiffness bring the propagation velocity similar to the near-metal diaphragm
• UDR tangential surround & spider are  equipped to realize the less anti-resonance and superior amplitude characteristic.
• The foamed rubber is chosen for the surround material. It has the lower density, lighter weight and higher internal loss characteristic than the conventional rubber and the foamed rubber surround has the low young's modulus and less eigentone.

Seas Prestige A26RE4 (H1411)

The A26RE4 is the modern version of the once popular 25F-EW woofer used in the Dynaco A25 system.  Seas has stopped using the old 25cm frame and now uses the 26cm frame.  This new woofer will not fit in the Dynaco A25 speaker anymore.

This classic paper cone has a wonderful roll off at 2000Hz.  This is one of the only 10" drivers we know of that could be used in a 2-way by letting the woofer run full range without a crossover.  I have heard this woofer with the Seas H1189 Tweeters and it had a magical retro sound to it.
