Hello guys, in the previous one I want to say that I have no experience with Caraudio. Now on the subject: I recently got a ESX subwoofer very cheaply on the flea market. Unfortunately the seller could not tell me anything about its performance, nor is there anything on the subwoofer (without housing), except on a sticker with “DS 126” and the serial number. Unfortunately ESX also has no homepage. By google I also found no more detailed information about this “model”. It looks similar to this model: http://www.audiodesign.de/produkte/esx/subwoofer/esx_sub_esseries.htm But it has a much larger installation depth! About 15 cm. Makes a very solid impression and is difficult to draw, I also think that it has two inputs for signals… Now I quickly put together a box and put the part in. I’m extremely surprised how much power and bass this bra ingt! I hope you can do something with it. Greeting Oliver87
