I have the Aker 10 watt from TK. I used it last weekend and typically keep the volume at 50% or so. It is a great piece and worth every penny. If you check my latest Youtube video titled"Thanks from Liq and Shelby" you will hear me with it on at about half volume. If you have it all the way up it is good and loud.
I actually installed a cheap voice changer in my helmet but it stopped working on halloween night and haven't taken a look at it yet. too lazy Where did you mount the speaker Liq??
Sorry to all those i have not responded to. I have not been getting notifications of this thread and never think to look here. I can give Y'all better prices on all of the aker amps by buying direct from me. That way ebay and amazon do not get their cut and you save $.
here are some youtube videos for those who were asking about volume and dimensions. I don't have any 12 watt or 16watt amps on youtube yet. i need to do a volume comparison video.
Here is a comparison chart that i made of available voice amps. I have owned and tried them all.
If at all interested best to contact me directly at familyjim72@yahoo.com. I do my best to help out the costume groups because that is also my hobby and passion.
