Update, May 2017, 10” subwoofers

The original Wavecor 10” subwoofers SW263WA01 and SW263WA03 have been discontinued. The reason is that the die casting tool for the old alu frame is no longer being maintained by our supplier. The tool has worn out and no exact replacement tool will be provided.
As a consequence Wavecor are no longer able to deliver any of the 10” woofers built in this old frame.

Two new units have been launched as replacements for SW263WA01/03: SW259WA01 (4 ohm) and SW259WA02 (8 ohm).
The new models are as replacements 99% identical to the old models in terms of Thiele/Small parameters. However, there are dimensional differences as shown below.
Additionally, the new models have been further optimized for handling large signals by being fitted with new and more narrow rubber surround. The new surround offers progressive end stop limiting to prevent very large input signal peaks causing high distortion or even damages to the voice coil or other parts.

In terms of T/S parameters SW259WA01 is considered a drop-in replacement for SW263WA03 (both 4 ohm) in the same way as SW259WA02 is for SW263WA01 (8 ohm).
There are, however, mechanical differences between old and new models that should be observed. Please see the drawings below for NOMINAL dimensions. The main differences are shown in red.

Acoustically/electrically there are no major practical differences between the old and the new models.
For comparison the relevant links are available in the table below.

While there was no choice regarding shifting to another 10” frame we did use the situation to introduce an important improvement. One limitation of the old frame was the rather short distance between the bottom of the frame and the gluing surface for the spider. This would always limit the amount of obtainable cone travel.
In the new frame the increased overall depth has been used to solving this problem completely.
Another improvement we have implemented was designing a new outer suspension (surround). The old surround was a bit too wide resulting in excessive stress imposed on the spider when input signals became excessive. This problem is now solved.
