Feature:
No features but it can handle a mid size room easy, oh it has a very nice and strong horn. You may want to eq it down some when played at high levels.

Quality:
Nice quality, well built and constructed with carpet covering looks nice and sound, great grill that bows outward to protect your woofers, nice quality for the bucks.

Value:
Its nice, Im hearing some Peavys may be more rewarding but not for the proce.

Desirability:
Looks good well made, wont make you salivatate but you will like em

Sound:
These speakers do exactly what they are supposed to do. Give you great sound quality. It doesnt give big boom for bass but it will rock the bass and for most folks in a small size room will like what they hear. I play mostly jazz and r&b and I also play a style of music called go go that very heavy on bass and bass drum. I'm able to play my bass through this cab (I have a pair) without any problems and I use a low b and it comes right on through.

Ease of Use:
Speakon connectors in the back. If you dont know how to plug it you shouldnt be into sound.

Support:
I havent needed them for this but folks here at zzounds answer that phone and answer all my questions.

Overall:
I run these through my pa system, I bought the zzounds pa package 3 with these and Im in love.

Feature:
basic by todays standard...

Quality:
They still work after a year.

Value:
Why pay huge money when you don't need to. Most manufacturers have building boxes down to an art. Granted the tech stuff isn't in these. But I don't need 1000wRMS, waterproof, directional horns, digital ready, delayed, or whatever. Wood cabs sound warmer than the lighter plastic. You get my point. New tech becomes old tech and old tech sounds the same as it did when it was new...but guess what...it devalues due to new tech, not quality. Still good gear, just not as fancy. Besides all that, your average Joe doesn't know the difference in sound. Only the music heads do.

Sound:
Any cab you buy will have it's own characteristics. By the cab best fitted to the room you play. 250 is more than enought for example, a 200 person sanctuary. This cab sounds clear and does punch the bass. No it is not a sub woofer. The highs can be stingy... eq them down. Not tough to do. Not a nasaly sound to these cabs. thats tops in my book. I hate too much mis.

Ease of Use:
Ive not had any problems adjusting for any room Ive played...

Overall:
Good for what I need.

Feature:
Speakon and 1/4" inputs, nice placement of handles.

Quality:
Cabinets are quite solid and the grills are beefy, they would definately protect the drivers if it was on the floor and somebody kicked it - might dent it, but the drivers would be undamaged. The carpet on my pair is fine, not coming undone and looks great. One of the screws on the stand mounts was stripped a little bit and I guess worked itself loose over the course of a month - dab of some glue and screwing it back in, haven't had a problem with it since. Probably got over-torqued at the factory. HF drivers seem like they could be better.

Value:
For 100-200$ less than Peavey SP5's and SP2's, I's a great value.

Desirability:
They looks alright, Flat black with a small orange, JBL logo square at the bottom. Peel that sticker off -if you prefer- and it'd disappear in a good setup. The flat black look makes it slightly menacing.

Sound:
For the money, these are some fairly decent cabinets. I like the sound they make, and they don't require a ton of juice, Quality of output is solid. The deep bass is quite lacking, but that is to be expected and you need a sub to reproduce the sound correctly with these cabinets. The HF driver, however, can make your ears bleed, This is not to say they are bad, they aren't, but they do add a very potent high frequency distortion that normal bookshelf speakers wont. I've been having to cut 3khz and up with a 3-9 db shelf with a paragraphic Eq when using these boxes at full power. Listen to a pair of those crappy MTX boxes that are sold at circuit city/bestbuy that 'LOOK' like pro gear, and hear how awful their horn sounds - imagine that, but MUCH MUCH MUCH less and NOT as bad, however it is noticeable - The HF driver in these is WORLDS better than those crap boxes. It seems like the HF drivers are a little too powerful to be matched with the mid/low drivers. So, use some treble reduction to save your audience's ears, especially in smaller rooms where people are near the cabs. They won't notice the reduction, and even if they do notice, after 5 minutes - their minds will have adjusted to the sound.

Ease of Use:
Know how to use an Eq, and these will be great.... It's a passive cab, doesn't get much easier

Support:
I haven't had a problem yet

Overall:
I'm quite happy with my pair right now. Now that I've heard the Peavy SP2 and SP5 boxes, I do want a pair of those, but they are almost twice as expensive. The JBL's do a great job for a starting DJ on a budget, I personally feel you can't do much better for the money. I've previewed lots of different brands at a few music stores, I even listened to JBL's MRX515 cabinet that's twice as expensive, and it didn't sound much better for the money. I am happy with my choice, at the time it was the best selection, I felt, for the money, but now that I've heard Peavey SP2's and SP5's - I definitely want a pair of those. Had I waited a few months and known they were going to be released, I would have gotten them. Much clearer, HF doesn't hurt your ears so much, etc.

Feature:
Has built in horn protection.

Quality:
Carpet tends to peel at the seems on all my boxes of this series.

Sound:
There is no comparison between these and the old TR series. For small to medium size rooms, this series takes care of business while sounding very impressive.

Feature:
quick and easy set up

Quality:
would be nice if they had corner protectors on them

Value:
worth the price you get what you pay for

Sound:
these speakers sound descent.but i would only use them in a small room

Ease of Use:
see above
