Hey there

So I think I have a problem with my VTF-2 (mk.1) subwoofer. Recently (and after many years of great performance) my sub developed an audible hum. Via plugging an unplugging and swtiching various components, power cables and whatnot, I'm pretty sure it's the amp itself (no hum was present before, and no equipment has been changed). Anyway, it was recommended by Hsu support to remove the amp and send it back for repair. I'm running into a little trouble with that part. I've unscrewed the plate amp from the sub, but there isn't much slack in the wire connecting the amp to the driver. I've only got enough room to slide the amp partially out of the way and slide my arm in. The wire connected to the driver seems to be attached at the very bottom, ie, the driver is between the connecting spot and myself, so I'm fumbling around blindy not really knowing how to disconnect it.

So, would anyone happen to have any pics of what the driver/wire connecting looks like?
Or, I was thinking of popping out the driver from the bottom to get better access, but I wasn't sure if the driver was attached to the cabinet with more than just screws. I unscrewed the driver, but it didn't seem to want to just "pop out" even with light force applied, and I didn't want to damage it in case it was glued to the sub body or something. Do I just need to apply a bit more force? Any help would be appreciated. Thanks.

Hi Craig,

On the VTF-2 MK1, the speaker wire slides right off the driver terminals. To make things easier for you, flip the subwoofer upside down (so that driver is facing up), remove the screws around the perimeter of the driver, put your hand through the amp cutout, and push upwards on the magnet of the driver to access the driver terminals. After you remove the speaker wire from the driver, then you can rotate the driver 180 degrees (so that the driver terminals are facing the amplifier), and finally you can put the screws back in to hold the driver. Note that there is nothing holding the driver in other than the screws around the perimeter of the driver.

Sincerely,
