I'm curious since the pricing is cheaper than Soundtraxx, but the additional paraphenalia to perform the programming of sounds seems to be a bit much. Why spend all the money for the additional hardware just to change the horn?
I have one and the sound is not even in the same quality as say MRC in my opinion. Tsunami for me is still the best.
I will make a separate post once I get it installed in an engine. From initial experience it looks like to get any sound you may need a 32 ohm speaker. There doesn't seem to have much power in the amp to drive an 8 ohm 16 x 35mm oval. I will have to play around with proper baffling to see if I can do something about the loudness.
