This review is from: Polk Audio PSW Series PSW505 12" Powered Subwoofer Single
Pros: About 5 years old and still going
Pretty loud in a room the size of a 1 car garage
Cons: As other reviewers have stated, it is loose and boomy sounding
Port noise can be horribly loud at certain frequencies
Fuse inexplicably blew after the first year
Volume/crossover knobs need cleaned, they developed noise when turning
Auto-clipping attenuation gets on my nerves (personal opinion, others love it) but in my experience it just forces you to always adjust gains/volumes per media if you're listening at high volumes
Other Thoughts: I am reviewing this sub for my brother. It has basically been through hell and back and is still chugging along. The sub was taken out and mounted backwards (It actually made quite a big difference in the 20-30hz range, and port noise isn't quite as bad), and it has even been temporarily used in a vehicle hooked up to a 500rms Pioneer amp (Yes it really pounds hard in a car)
The inside of the enclosure is pretty interesting and answered my question as to how a sub in such a small box can reach such low frequencies. The port, although tuned well, is too small for a subwoofer with such high xmax, which causes port turbulence (noise) when the sub reaches xmax.
While not an expert, I have designed, tuned, and built many subwoofer enclosures, none of which I've had any problems what-so-ever with port turbulence. I understand they want the sub to be small, but that doesn't mean they have to make the port so small. You CAN design a small box with sufficient port area to alleviate port turbulence and still stay within a reasonable tuning frequency with reasonably flat response.
Also, IMHO, not a fan of rear-firing ports. I've achieved the best results when the port fires the same direction as the woofer. IE: port and woofer firing into the corner will yield positive gains in output. With this sub, it's either the woofer or the port into the corner, not both, so output suffers somewhat. In the case of this sub, it's best to fire the port into the corner (just to help hide the port noise)
This review is from: Antec EarthWatts EA650 650W Continuous Power ATX12V Ver.2.2 / EPS12V version 2.91 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC "compatible with Core i7/Core i5" Power Supply
Pros: Works great
Underrated (Output 69A@12V = 828 watts)
Input current: 10A@120V = 1200watts
+3.3V@25A, +5V@25A, +12V1@22A, +12V2@22A, +12V3@25A, -12V@0.5A, +5VSB@2.5A
3v rail = 82.5 watts
5v rail = 125 watts
12v rail = 828 watts
Combined total wattage = 1035.5watts
Cons: Only the PCIE and main board plug wires are jacketed
Green sticker and gray case aren't the most aesthetically pleasing
Other Thoughts: This PSU is now on its 5th year in its 3rd computer.
It is now powering a 125watt AMD FX8320 processor and a 300watt R9 290X (that "requires" a 750watt PSU), the mainboard, a hard drive, and 8 fans with no problems what-so-ever.
Rips through everything I've tried
Not loud at all
Might be overkill for me, but the price was unbeatable
Cons: Black screens
(Note: these issues have disappeared, see other thoughts)
Other Thoughts: My TV sends incorrect maximum resolution information to the computer through digital connections. This is not the cards fault (although it would immensely help to have at least one DVI-I, instead of only DVI-D), but I had to buy an active DisplayPort to VGA adapter to get full resolution on my screen.
When it was hooked up HDMI to HDMI, I would get random black screens (no crash, just flashes black then the screen returns, same as when installing drivers) and some green artifacts when the black screens would occur. This is supposedly a driver issue, but it doesn't explain the following:
Using the active DisplayPort to VGA adapter has caused these issues to disappear. I'm not sure why, but I couldn't be more pleasantly surprised.
Temperature: I was expecting this card to hit between 70c-80c without even trying. My old 7850 would hit 70c. So far, the highest I've seen this 290X hit is 55c after two hours of Arma 3 at max settings. (I always keep fan set at 100%) Idle temps are around 29c-32c. I have 8 fans in my case and this may be a contributing factor to the low temps, but again, pleasantly surprised.
Size: This thing is big and long. It is so long that it completely blocks the bottom intake fan in my case. This has caused my CPU temps to increase by almost 10c under load. This was an unpleasant surprise as I now have to search for a better CPU cooler.
Noise: I can't hear it even with fans at 100%.
Power: I'm running this just fine with a 650 watt Antec power supply. I know it recommends 750 watt, but that rating is for the simpletons. This card draws a maximum of 300 watts continuous RMS under load which is approximately 25amps. My PSU supplies a total of 69amps to the 12v rails, which leaves a generous 44amps for the CPU and MOBO, even though it's only rated at "650 watts". Not all power supplies are the same though, some are underrated and some are overrated, so be careful and always go by the AMPERAGE, not the wattage! If your PSU is less than 45-50amps at 12v, I wouldn't try using this card with it.
