Scott joins Leo to talk about a new sub-woofer from KEF. It's called Uni-core and it uses two speakers that are opposed and use force canceling to eliminate the resonance so all you hear is the low-frequency sound. The result is a pair of tiny subwoofers that can broadcast 11hz, way below what we can hear. Read more about it in Scott's TechHive article here.
There's a scandal brewing over at Amazon, where the online retailer has pulled all listings to sell Apple TV or Google's Chromecast because there's no app to support Amazon streaming. They also won't allow third parties to sell them. That's scandalous, but Leo says that while it's rather bad form, a store has the right to carry what it wants to sell, so there's really not much to do about it. Scott also says it shows just how serious they are about streaming TV.
Scott got a question asking if the Onkyo TX-NR646 AV Receiver has two subwoofers, and it turns out it does. It's much better to have two subwoofers than one to make the bass response smooth. They produce the same signal and if you only have one output, you can use a Y Splitter, as long as the subs are powered.
Scott and Leo also talked about in ear headphones and how they effect hearing, so it's always important to keep that in mind when listening to your music.
Scott got a question from Dominick about whether he needs a sub woofer. He lives in an apartment and he can't get anything too big. Leo says that a sub woofer got him in trouble when he was living in his studio apartment. Scott says that's because of the low range of the woofer that travels very far, and even if it's not at high volume, it can really carry in every direction. Where would he connect it with a two channel system anyway? Scott says that most preamps have two sets of speaker outputs.
