Pioneer Andrew Jones Designed 100W Subwoofer

About eight months ago, I realized that I was spending far more time listening to music at my desk(in a big window looking at big mountains!) then on my main music system, in part because my computer is there and I love using itunes with my 2000 favorite songs for music selection. After going through three sets of ever more expensive and ever better quality computer speakers, I ended up with audioengine a5+s, which compared very favorably to the sound of my higher end living/TV room speakers. At first the a5+s were punchy enough, but when I'd listen to the same song in the living room or on my high-end car system, I realized that there were bass sounds--and feelings!--that were missing in my work room. I also realized that I had never liked subs because so many of my friends and associates with subs had way too much boominess for my taste. And so I bought this subwoofer, the first dedicated home subwoofer I've ever owned(yes, my vehicles all have subs). Its like a revelation: there are deep bass notes even in acoustic guitar music that I was missing in my office and lots of deep bass in movie scores. Though I'm a rock and roller, I don't like heavy or boomy bass, so I like being able to experiment with adjustments to the volume and roll-off so that the rumble and and bass drum thump are there without overwhelming the precise yet sweet a5+ sounds. I found that just a quarter turn for both volume and cutoff gives me clear strong bass notes and some heart-shaking vibes without even a hint of boominess. For relatively small money this speaker does exactly what a music afficianardo like me craves. Highly recommend PS: I got the factory refub a5+ direct from audioengine for $329 and this sub on special from Amazon for $99. So for $429 I have just a superlative sound system.
