Feature:
It has a built in crossover and volume controls, clip light, and high pass outputs. Could of had different types of inputs other than just XLR's.

Quality:
The box is made well, but could use a better amp and speaker. The amp says it's 500 watts which doesn't seem accurate. But this could be because of the low efficiency speaker. The amp also overheated on me during a jam. It was VERY HOT! I thought it was going to blow up. Needs a cooling fan.

Value:
This is alot cheaper than any other powered sub in it's price range.

Desirability:
I sold this sub, so I guess that means I don't want it.

Sound:
The sound is ok. Doesn't have the punch I thought it would. Low efficiency speaker. I don't think it's made for live music but would do the job for a DJ.

Support:
I'll give the support a dead center 5 because I never dealt with them.

Overall:
It needs work. Would do the job for small DJ rigs, but not for live music. It's just too weak to handle a bass guitar or kick drum. I wouldn't count on it though, as it overheats easily.

Have used other powered subowoofers, but none have been as definative and punchy as the Samson....really. It's connections are lacking a little with certain configurations, but that can be worked out.

Feature:
Didn't need the castors so I left them off.The rubber feet leave black marks on the carpet if you drag it around. Amp is of a "Carver" sonically clean design and turns on automatically with any signal and off automatically with the lack of input signal, after a delay of about 5 minutes. Great feature for home theatre but can be a noticable low thump if you have the signal too low for too long.

Quality:
Cabinet is pro grade period. The 15" speaker is a British designed Celesteon unit with cast frame and long lasting Butyl rubber surround. Even at rage party levels it has never over heated.

Value:
Have to give it a 10 here due to the low price vs. sonic accuracy times SPL output times plug and play ease.

Desirability:
Yea , sure I want another one but I don't need it in the home arena. Two would make any mid size hall thump. Put this under your desk at work and connect it to your PC and get fired. This unit would be well suited to pro installs such as board rooms and small clubs and houses of worship. I do use it for mobile dj parties on ocassion.

Sound:
Home theatre use is one of best places for this value added sub. I have it tucked away behind the couch and it really compliments the other 2 main high efficiency JBL pro speakers and a PAS coaxial center channel monitor. Build this into your next pro home job and it won't disappoint. The amp is silent with out a fan and no hum to speak of. Plenty of chest pounding 30HZ waves(and below)due in part to the butyl rubber suround on the long throw 15" driver.

Ease of Use:
Plug and play ease. Minor adjustments to gain and crossover pots needed at first set up. The home theatre amps have adjustments for all of the other sub line out parameters.

Support:
About one year in now and the unit is on 24/7 with no need for support.

Overall:
Low Dollars + Quality real Celesteon speaker driver + "Carver" quality amp = I can't beleive the audio file magazines haven't picked up on this secrete weapon. Disclaimer: Not Recommended For Apartment Use Unless You Want To Meet All Of Your Neighbors And The Local PD.

Feature:
has every feature I could ever need

Quality:
The stereo/mono switch keeps going out, causing the speaker to fail. been repaired twice in 6 months.

Sound:
the sound is quite good, for the price

Support:
All repair shops in my area have stopped doing Samson service. For warrantee work my options were to ship to NY ($80) at my cost or pay an independent tech ($75). I chose the latter for time reasons. I have never been able to get though to their customer service via phone, leaving countless messages.

Overall:
if it would just work consistently, it'd be great...

Feature:
The variable crossover frequency is nice when the sub is the last in the chain. The LED on the back is helpful to kep it from clipping.

Quality:
I have been running a pair of these subs for 2 years. I have had the same problem with both of them. The 4 ohm speaker in them has a maximum of rating the same as the amplifier that is in them. WARNING!! Do not turn this unit on with signal going to it. It will destroy the speaker.

Value:
With aforementioned stated problems. It's been more trouble than it was worth. If you want or need a powered sub get the Mackie or the QSC powered subs.

Desirability:
It wil do in a pinch but definately not suitable for main line production or use. it would compliment a home stereo or home theater well or use in a small venue or room.

Sound:
Sounds good at lower levels with the controls set right. The high pass crossover makes the Mackie SW450's sound bad and taints the entire setup. These subs need to be run in tandum to get any exceptional benifit from using them.

Ease of Use:
Having to place it last in the signal chain is a pain. The wheels and adjustable frequency can be confusing for those who have no knowladge of such a thing.

Support:
Had to replace the amp in one and they sent me the amp after I paid for it but refunded the cost when I sent the defective one back. The speakers failed in warranty and Samson would not replace them.

Overall:
Need to find a more reliable sub than this one if you plan on buildinig a pa system for bands, dj'ing, karaoke, or any other live music application. It would be suitable for a stage monitor if you needed more kick on stage.

Sounds great when it works, amp seems to over heat very easily, needs a cooling system.

Feature:
The sub having wheels is a great feature. Wheels and low wt. was a big selling point for me.

Value:
It $500 this sub has been a great buy so far.

Sound:
This sub has a very good sound and this is my second time grading it. With the settings set properly, this sub has big bass.
