hey guys. i have a tips for those of you who're using
Edifier C3 and claim there's
not enough bass. This can be applied to other models too.
First off, my Cambridge Soundworks Megaworks 550 stopped working when i came back from a month of holiday. Being busy with work, I decided to accept it as a loss and not fix it anymore. Previously spent so much time and effort to fix the subwoofer and even replace 2 satellites which i accidentally dropped.
At the edge of deciding whether to sell or throw the subwoofer away, I came across a very interesting idea: use my Creative Inspire 2400 amp to drive the subwoofer. At first I was hesitant, because the amp only uses TDA8510J and 18VA transformer. I estimated it to juice out 10W of power to the subwoofer channel, thinking that it wouldn't be able to drive a 8" 150W megaworks sub properly. The subwoofer cone is dual-voice coil (DVC) type with 8 ohm each, so paralleling them will make it a 4ohm sub.
So I tried it anyway, with some thin piece of wood as the backplate with added MDF that i found laying for added rigidity. Upon completing the assembly, to my surprise, the MDF almost wasn't strong enough to withstand the bass of the subwoofer,
even when it was given a mere 10W of power, with the bass knob at the lowest level to prevent distortion and clipping. Even at lowest setting at the bass knob, it was much louder than it was on maximum of the original 5.25" 15W subwoofer cone.
Due to the high level of failure of Megaworks / Gigaworks PC speaker, i believe many of you can
find those faulty sub for a very cheap price, and salvage the subwoofer cone itself. If a 10W amp can drive this subwoofer, sure the 30W C3 amp can drive it better. Edifier C3 already uses 8" driver, so it's just a direct swap. Just a note to remember, start with lowest level of bass setting on the C3 and raise slowly until you notice any distortion.
Anyway apologize if this doesn't involve Edifier product, but I was a proud owner of multiple Edifier speakers. It's a shame I don't have my R501 anymore, otherwise this subwoofer will be planted there
