Ease of Use
How easy is this product to use? How easy is the product to use with other products? Did it take long for you to learn to use this product? Was the manual helpful? How playable do you consider this product to be?
Very easy to install with quick connects
How is the tone?
Deep, full lows while still retaining mid attack and more than enough clarity in the highs. They sound better than the celestions I was using.
