I don't think there is a consensus on these things...... 20 different people might give you 20 different answers.
I did a lot of youtubing during my search and they all sound great imo and they all weigh much less than the OEM boat anchor.
Most all of them seem to have some drone, no matter if they claim they don't..... just going by real world reviews on most of them.
I ended up going with the Top Speed Pro 1 due to its sound and unreal price!!! Figured if I'm gonna have drone with just about all of them I might as well try this one out and save $$$
The weight saving alone was worth it, but the sound is what it's really all about.....
yes, there is drone, but it is easily avoided by shifting out of it and it really only happens when bogging
Here is my before and after vid
