JBL 308P MkII is rated 4.5 out of 5 by 2.
Rated 5 out of 5 by from Good Sound Good Sound, quality, comfort & Bass. The best speaker ever I have.

Rated 4 out of 5 by from great price The price was good on sale as much as the 305's. I like that the volume knob has the bumpy stages that way a pair can be accurately synchronized to the same volume. The highs and lows frequency adjustment switches are also a life saver since my room is not sound treated. They sound great honestly, they really shine when playing music but as a multimedia speaker for live tv they arent as good. I used them for my tv and everything sounds better but in movies dialogue is always much louder than any of the mids in the background. There are a few issues but not gamebreaking. 1. there is a hiss or fuzz thats audible when you get up close to them, this doesnt bother me b/c i sit far away (5-7ft). 2. There is no mesh screen for protection and that means you have to make your own. 3. The rear port looks really underdeveloped, what i mean is that the port is basically just a hole. When i shined a flashlight i could see everything on the inside. The tweeter is super exposed so if you have kids make sure they never get back there. Also the tweeter is not isolated from the bass in there so there could be distortions caused by strong bass. The tweeter also looks really simple from back there like it didnt cost much to make and install. Anyway im still very satisfied and love the jbl quality of being confident in turning up the volume without fearing of cracks n popples. I would recommend for their next iteration to add a second tweeter or a mid range tweeter. Make it a 3-way speaker to blow up all the mids to be as strong as the highs.

I was wondering if a pair of these would be good to plug an iPod in direct for music&nbsp;

Asked by: Bo2484
Yes I use an 1/8 inch stereo headphone jack split into 2 male XLR's and play music through the JBL's from my computer or directly from my phone and they sound incredible. No interface needed. The JBL's will take either XLR male or 1/4&quot; male inputs. Both sound great and you can buy those cables at Guitar Center for $15 to $20. I have the LSR 305 JBL's on my desk and they are amazing. So good I bought a pair of them as a gift for a family member.&nbsp;

Are you able to plug a dynamic mic directly into the monitor and use for a small meeting?&nbsp;

Asked by: Htxsw89
Great question! I have a compact 4 channel Mackie mixer board that accommodates two wireless microphones and two 50ft corded mics. You must have the proper cables and adaptors to make it work for you. You don't need a degree in audio enginerring to set this up...try it today....thank me later.
