Good cabs but can be a bit too loud
The quality of the cab is top-notch. Now about the speaker, from what I inferred they are designed by Eminence and are quite similar to Private Jack. They have more low-end which makes them sound beefier than Private Jack speakers. Those speakers sound really loud though, and the 4x12 cab loaded with them sounds too loud with my BV150H for indoor usage, but I paid barely $300 for them so I ain't complaining.
