Question: One of my satellites died, where can I get a replacement?
Document: I got this 2 days ago, the first one i got was defective ( the IR receiver keeps shutting off), i returned it to Bestbuy and got a different one. I didn't know that in order to hook the xbox up, you will need an "advance av pack". That's all you need to get, the optical cable is included in the package. I fired up the "Saving Private Ryan" dvd, i was amazed. It was like you're inside the movie.
If you could possibly surround it with 2-3 walls, that would be ideal. The trick with the sub is to balance out trying to get the &#34;feel&#34; of a boom without making the sound overly &#34;boomy&#34; or one-dimensional.
Occasionally, she'll freeze up and repeatedly begin to shut off until powered down. I remember people speaking of such behavior before their system died (this is also similar to the behavior of systems that died within a few months of purchase). Although, purely because of how it's happening, I can't help but wonder if it might not potentially just be that the fuse in my system is going bad.
Ok, to start off I'm not an audiophile. I have used and dived into tens, if not hundreds, of audio and video devices and systems. I get to know what I buy and don't stop at just getting a component to work.So far, this system is performing well, but the sound quality I was expecting, expectations can jade ones experience if they are too high, was not quite there.
Mine isn't as thorough as everyone else's review although it's been several years since the company has not been in business, I'm so happy that it's still functioning just as strong as the day I got it.. and it's still as clean no scratches, just wished the company was still around to buy other optional items, so for those who are lucky to find on also intact, get it asap.Game on!
I've done my research and I've purchased this set for myself. There really is nothing that compares to the Spherex system within the same price range. Some might be discouraged by the Xbox logo that is on every component of this system. Some might think that's cool. Others might get the notion that it might be cheapy and/or low budget. Trust me on this...it is far from cheap. When I unpackaged my spherex system, I was amazed by the quality of each component.
Its sound stage is incredibly wide and deep, especially for my small living room. The treble is smooth, not fizzy. The subwoofer is full and tight-sounding, perfectly matching the satellites. I then hook up my home theater PC to it and play my classical MP3 collection ripped at 256 kbps via the Dolby Pro-logic II mode - again superb sounding.For movies the Dolby Digital and DTS works superbly as well. The sound stage is again incredibtly wide and immersive.
Hopefully we would get more updates from the website, especially for the remote. Overall i would rate it a 5/5 (provided a update for remote is available pretty soon)
To think I purchased this to go with my original Xbox and it had performs flawlessly with the Xbox 360, Xbox 360S and new Xbox One.
video games are so much better when you hear them in surround sound. you can hear the bad guys behind you! this is the way games were meant to be played. this system has everything you need in the box to get surround sound. spherex is cool.
Answer: Really Really hard to find,try just buying another speaker and hiding it,amazon has some nice satellite speakers,and they also carry the adapters to hook it up to your subwoofer.
