Feature:
No extras included. It does what it does.

Quality:
Everything is fine except for the feet. They are crap! They pull, roll off the cabinet with the slightest sliding motion in moving them. The front two can be fixed, improved but the back can't without building something onto the cabinet to re-attach them to.

Value:
So far, appears to be a great value considering performance and cost against other brands.

Desirability:
A functionally attractive aesthetic. Not an impulse buy sort of thing as if you came across a vintage Les Paul and you could afford it.

Sound:
Sounds great for our roots rock band. Adding them made the difference in sounding like an "Act" as opposed to a garage band.

Ease of Use:
Straightforward, simple.

Support:
No issues so far that require support. Just hoping if it came to it.

Overall:
After a year, they still do their job well enough that any shortcomings can be overlooked or tolerated. I will probably keep using them until our PA/Sound is somebody elses problem to deal with.

Feature:
No accesories I know of... USeful features were that they were 8 ohm each and daisy chained to 4 ohm for amplifier matching.

Quality:
Very unhappy with quality. We are a part time classic rock band, had these less than a year, absolutely did not over power or under power them and one of them had major driver failure. Our sound technician (very technically trained) opened them after getting them back from Yamaha service rep, and up found no evidence of "burning" as the Yamaha service rep at warranty center claimed it had. (They refused to honor warranty and replace driver as result of their "diagnosis".) Our sound technician sent a letter and comparison pictures of what a real "burned" driver looked like and a picture of our driver they said was burned, which did not have a scorch mark anywhere, and we recieved no response or compensation from anyone in the chain of service.

Value:
Not worth it in my opinion.

Desirability:
Was suppose to be a practical addition to our setup...

Sound:
The sound quality was about average.

Support:
...as mentioned in "Quality" section, they refused to honor warranty and replace driver as result of their "diagnosis". Our sound technician sent comparison pictures of a what a real "burned" driver looked like and a picture of our driver they said was burned, which did not have a scorch mark anywhere, and we recieved no response or compensation from anyone in the chain of service.

Overall:
Very disappointed...replaced drivers in the cabs with another brand, on our own, at additional expense.

Sound:
I've got two of these and the sound is great but they don't handle that much watts if you ask me,well basically they didn't last that long because i didn't even have them for more than a year and i had to recplace my subs with a pair of pevey's which have serious bass but other than that they are pretty good speakers

Feature:
Speaker comes in a box with a small guide outlining the frequency response. No accessories promiced, provided, or expected.

Quality:
Cabinets are solidy constructed and heavy. Better speakers would probably turn these into some really nice subs. I wonder if the Peavey Black Widows will fit...

Value:
I got 4 of these as refurbs for $320 each with free shipping and regret the purchase. Good price if they had lived up to expectation, but they didn't. Very glad I didn't pay full price!

Desirability:
Wanted it before I got them, now I wouldn't have another one.

Sound:
More accurate and efficient than my Madison 21" subs at low volume, but these don't handle high volumes well at all. I ran 4 of these off a Behringer EP2500, delivering up to 600 watts per sub (per spec). At around 40% power the subs started breaking up. No amount of sound board and EQ tweaking could make these things happy at concert volume (heavy metal) so I didn't use them. Country or gospel shows would probably have better luck.

Support:
N/A

Overall:
I'll probably run these at smaller shows with a Behringer EP1500 and a for sale sign until they're gone. A pair would fill a small room where I wouldn't be using lots of power anyway, so I'll probably get my $300 per speaker back sooner or later.

Feature:
they came with nothing but i didn't expect them to come with anything. a mounted set of wheels would have been nice.

Quality:
the cabs seem to be strong but one of the subs was dead out of the box and it took some work to get a replacement

Value:
if your planning to use them for a small to medium room they will do fine but if you want some real punch at concert level, spend the money and get some mackies.

Sound:
Somewhat of a dissapointment. i have them matched with Yamaha's P5000 amps. they sound great at lower volumes but at comcert level they get muddy.

Ease of Use:
they hookup well with the yamaha matching amps and club v pa speakers.

Overall:
the price wasn't bad and they work pretty well if you don't push them but for a little more you can get subs with higher output and more punch.
