Yamaha DTXpress/DTXplorer/DTXtreme

I'm not completely good on this subject...but here are the ones I 
have used Pintch sets on that are worthy of applause. The Fender 
Passport systems are nice to use, as they can take those low end 
sounds without loosing power/volume...probably one of the best 
portable systems on the market. They come in different sizes and 
specs. Behringer monitors, JBL Monitors (I think thats the company), 
and there is one other company, I'll have to get back to you on that 
one. The one I can't rememeber is the company I am Buying some studio 
monitors from.
