Question: Acoustic Audio RWSUB-8: How do you connect it to your "sub" output? This has line inputs for right and left. Do you just connect one or look elsewhere
Document: To be fair, the speaker is only designed to reproduce between 26-200 Hz, so the amplifier needn't have a wide bandwidth of power. Realistically, it puts out plenty of power. It pairs nicely with my Pioneer VSX-D509S receiver, which is rated 100W per channel, RMS into 8 ohms. I can easily blast myself out of the room. [(Edit) Mine is the Acoustic Audio Cinema CS-PS8-B, which is a front-firing version of this product].
It goes well with my black ash System 21 office furniture. The subwoofer offers both high level inputs (speaker wires to a built-in crossover) and low level inputs (from your receiver's RCA "subwoofer" output). There are adjustments for the cross-over level, and for the gain control. I found it easy to set it up to make a smooth transition between the bookshelf speakers and the subwoofer.
Having spent 18+ years in the audio industry, I am tempted to write a tongue-in-cheek typical audiophile review, evaluating whether the bass produced by this sub-woofer is well-defined, versus "boomy" or "tubby," as if it were a Martin Logan or comparable.
Just play some regular songs, then slowly turn the bass up over a couple of days. Then play some actions scenes through it a few times. Idk about its advertised 300 watts max power, but this thing gets pretty damn loud! Shakes my entire house when I turn it up. I totally recommend this buy if you're looking for a small, cheep sub for all audio purposes.
I'd been looking for a subwoofer to use with a Squeezebox Boom internet radio. This one works very well with the radio, filling out the bottom end nicely.It's possible to make the subwoofer come across as boomy and muddy sounding, but to do that you have to turn it up too far (which is what most people do). To get the right level, I set the rolloff control about halfway (have no way of knowing what frequency that represents) and turned the level control all the way down.
This works great for me. Adds the base we need at a good price.i love the auto off feature. I don't have to worry about it being left on
The reason for low frequency extension in audio applications is to provide a presence and warmth to the reproduced sound. While many are drawn to a &#34;thud&#34; or &#34;thump&#34; factor, these are just physical manifestations of what was actually engineered to be &#34;presence&#34; -- something sensed aurally and physically -- in the recording.
This sub does that, but I didn't buy it for the vibrations. I bought it to fill in the low end where my bookshelf speakers just can't go...and this little beast does that effortlessly by filling in the extensions of a recording that my monitors weren't engineered to reproduce. There is a thump when called upon to punch me in the chest, but more importantly this subwoofer fills in the gaps that we're missing from my two channel setup designed specifically for music.
Got this sub off of Ebay at auction for 50 bucks, half its list price! I looked into the seller of this item. Everyone had beef against them for some reason. They are great and completely reliable, you just have to work with them via email, etc. This is expected from any company. I heard that there products suck, but I checked forums and read reviews of professionals who have tested this product, and this proved to be a great sub for the price!
In my bedroom I watch TV on a 50 inch flat screen and run the sound through an AV receiver into two very high-quality bookshelf speakers rather than using the internal speakers of the TV. I bought this sub woofer just to fill in the low-frequency sound that I felt I was missing. To say I was pleasantly surprised would be an understatement. With the volume turned up to about 55% this baby can shake the room.
Answer: If your audio interface has only a single RCA line out for sub pre-amp, use the provided RCA splitter to split the single line to a "right/left".
