HK Stereo System Choosing Speakers Choosing an Amplifier Fighting Amplifier Heat Six Month Update a/d/s/ Subwoofer |
October 25, 1999
By: Robert Leidy
My HK subwoofer was rebuilt by a/d/s/ as a development project while they were evaluating the possibility of making a speciality kit. The product they created works very well, however it was determined that the stock HK amp was not powerful enough to truly drive the (now) a/d/s/ subwoofer with enough power to audibly tell the difference between the stock sub and the much improved a/d/s/ subwoofer. As a result of this, a/d/s/ canceled the project.
The individual within a/d/s/ that had done the research and development of the prototype replacement subwoofer got permission from a/d/s/ to build the subwoofers on his own for those HK owners that had also replaced the stock amplifier. However even that project was canceled with the news that BMW had a new HK subwoofer with the model year 2000 Z3.
So as it stands I have the one and only a/d/s/ prototype subwoofer. I do not have any details about the drivers, they were specifically unmarked so I can't tell you anything about them from looking at them. All I can add is that they sound very good and its a shame the way things worked out.
