No not sloppy bass
ports are made to specific size for best results. Here is an example of what you are saying. If there is no port air has no where to go therefore it bounces around in box causing distortion!!! Also try blowing air into bottle, you can't because there is no where for it to go. Now how can a speaker move without airflow, it can't so therefore it doesn't work to its full effect and distorts 

one other thing Jimmy called me today and told me how to update it and it really helped the unit sound more crisp and added controls on front panel for my Iphone
what if i were to take the 2 coaxial drivers and put them in the JVC.. hmm.. will finally get the tweeters it needs hehe.. not sure though.. the xover on the JVC might not give me anything but low frequencies.. gonna try it using the 2 speaker boombox woofers.. so as to not blow my 3 speaker speakers.. should be quite interesting! i'll follow up in the next few weeks when i grab one of the 2 speaker units.. unless Blu-Fuzz has any extras from his parts box he would be willing to sell?
