Seas A26RE4 (H1411) Classic 10" Paper Cone Woofer
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 tweeter and it had a magical retro sound to it.
- A classical paper cone and matching natural rubber surround produce a smooth response and reduce potential resonance problems.
- A four layer voice coil provides a well behaved roll off characteristic.
- The magnet system has a T-shaped cross section of the pole piece for low modulation distortion.
- Extremely stiff and stable injection molded metal basket keeps the critical components in perfect alignment. Large windows in the basket both above and below the spider reduce sound reflection, air flow noise and cavity resonance to a minimum.
