    • Great speakers!
Size: 12-Inch Speaker
Bought the "used-like new" and it really is. Speakers look brand new and sound great!

    • Oh yeah!!!! JBL Delivers Excellence
Size: 15-Inch Dual Speaker
When JBL said these were "Entry Level" professional speakers, I was a little concerned. Entry level usually mean bottom of the barrel even if they are pro speakers. Well... If these are "entry level", then they are the best entry level speakers I have ever heard. The range of sounds from these monitors is impressive. Before I start, a few must know': Must Know 1 - These are passive speakers, which mean YOU WILL NEED AN AMPLIFIER to get sound from them Must Know 2 - Just because you have an amp, doesn't mean it will automatically sound good. You will need additional equipment Must Know 3 - This is a black carpeted box made from wood Must Know 4 - If you do not understand the particulars of passive speakers, you should not buy one. Must Know 5 - Yes it uses speakon and 1/4", but if you are going to use these for mobile work, get speakon cables Must Know 6 - Yes, they are loud, Yes they produce lots of bass (its a double 15" box) Your final sound quality and experience with these boxes will depend heavily on your equipment setup. You need a quality amplifier, and you will need something to drive that amp. You can use a quality preamp or equalizer or crossovers or mixers etc. etc. etc. Whatever you choose, once you get it tuned and dialed in right, the sound these boxes make will blow your mind. In the week that I have owned these speakers (I bought two), I've played an outdoor gig for 400+ and indoors twice. These boxes deliver super clear top, because I have dedicated bass boxes for my outdoor event. When inside however, I didn't need my subwoofers, because all I needed was a little 63 & 80 on my EQ, and these bad boys delivered thunderous bass for 6 straight hours, play top end flawlessly. First chance I get, I'm buying two more of these, and use my active speakers for rear sound enforcement. ... show more

    • Get yourself a hand truck/dolly to move.
Size: 15-Inch Speaker
Speakers are loud, and do have good bass. They are hefty [60 lbs each], so do take that into consideration, if you plan to move and set up these bad boys a lot. As a DJ for many years, I must state, if your looking for crisp highs & clarity, these aren't the ones. Even with a high quality EQ, which did help somewhat, these are definitely stage/party speakers, where volume, and not clarity, are the primary focus. They are however JBL's, so I expect them to hold up for a while. ... show more
