An excellent choice for limited space and money. (however.....)
on June 29, 2014
Like many others, I fret over spending any hard earned money on audio upgrades. I looked through myriad of options and configurations, front firing, down firing, dual side firing, passive radiators and what not. I have had a number of front firing subs, including a Klipsch 10" digital amp that became very disappointing as I increased the quality of my stereo speakers. It was a great sub for home theater, but when I went to a 2 channel only, the Klipsch became an obvious weak link. The reason why I say this is only for background. I've had a down firing Yamaha that bottomed out quick, I had a big JBL 12" that was okay, mostly rumble and boom, no detail or clean drum strikes.
I took a chance on this sub because I could get it direct from Polk Audio as a refurbished unit for only $299 delivered. If it was a bum, I wouldn't cry in my beer over $300 bucks. Well, I am more than surprised and happy with this sub - as a matter of fact, I plan to add a second one later on.
I am running this amp with a 12' signal cable, upgraded ZU Audio power cable and it sits on a 3/4" custom cut pine plinth with the spikes solidly stuck in the wood. I pulled out the cheap fill and put in Fiberfill. I had my audio buddy over to listen and I played "Fanfare for a Common Man" and we both sat in shock and awe. The bass drum thwacks shook my water cup like the scene from Jurassic Park. It was clean, loud and had good note detail. Yes, this is no SVS sub, but for $300, I have not owned anything that comes close to this level of performance. I was able to integrate this sub in with very detailed sounding KEF R300 monitors. Best money I've ever spent on a speaker, bar none.
So this unit decided to crap out in less than a year's use. I leave this unit on standby as it had no issue with auto on function from my pre amp/DAC. A few nights ago my wife and I are startled out of bed because it sounded like someone is running through our house. I jump out into the hallway to darkness and nothingness; yet the noise I am hearing is bizarre. I am searching all over the kitchen and living room for a strange pulsating sound to find out the subwoofer servo went out and it was vibrating on its own. I unplugged it, tried to reset it, moved it to another location just to be positive and sure enough, 6 months of use and it is dead. This was a refurb unit from Polk Audio - never again. I am changing the rating to reflect short life span of product.
