1528 Series Subwoofers?

At the moment there are no subwoofers planned for the 1528 Series 8.
The speakers in this line are very much full-range and will not need subwoofer support to sound complete with most music.
For movie playback you can absolutely add the current 1723 Subwoofers. They are a great sonic match and will blend very well with the 1528 speakers.
