I'm in college, and don't have much to spend. I basically want some speakers i can hook up to my tv and also bump some music on. I see good deals on MA audio, but i read it's not very good.
Answer
First off, you are not going to be able to connect any speakers to a tv. The only audio output the tv has is through an optical audio port. This is a digital signal that is encoded by a Dolby Digital and needs to be decoded by a multi channel receiver, home theater in a box with an optical audio input or a sound bar. By staying with name brands like Definitive Technology, Energy, JBL, Infinity, Klipsch and Polk audio you would get good clean sound. I do recommend you demo any speakers first and let your own ears be the judge. Hope this will help you out.

Speaker wiring question?
Q. so i have a sony hifi system with a 6 ohm amplifier. the speakers that came with it are obviously 6 ohms....there wasnt enough bass so i purchased a pair of 8ohm dj woofers, because i know that if u have a higher number of ohms you can use it no problem on a lower number ohm amp. anyway, i was wondering if i could have the 6 ohm stock speaker and the 8ohm dj speaker running out of the same terminal. i was doing some research and i found out about parallel speaker wiring, and it changed the resistance of the speakers or something. ANYWAY i was wondering if it is okay to wire an 8ohm and a 6ohm speaker in the same terminal or if i have to spend even more money and get a separate amplifier
Answer
>system with a 6 ohm amplifier< Amplifiers do not have resistance, at least not in the aspect to which you are referring. Amplifiers will have a rating of what speaker impedance they will tolerate. Usually an amplifier will tolerate a range of nominal speaker impedances, for example 4 to 16 Ohms.
> i was doing some research and i found out about parallel speaker wiring, and it changed the resistance of the speakers or something.< It doesn't change the resistance of the speaker, it changes the combined impedance as perceived by the amplifier. Parallel wiring of two identical loads will half the value. For example 8 Ohm + 8 Ohm = 4 Ohms. Series wiring will double it. For example 8 Ohms + 8 Ohms = 16 Ohms. Amplifiers will generally tolerate higher impedance numbers better than lower impedance numbers. If you simply unhooked the wires at the speaker and twisted them together, this would be 0 Ohms and your amplifier would either destroy itself or engage the protection circuit. In your case, wiring your 6 and 8 Ohm speakers together in parallel will result in Approx. 3.5 Ohms. Wiring in series will result in 14 Ohms. As you can see parallel wiring is unacceptable for your Sony receiver. It would probably trigger the protection circuit if you turned up the volume loud enough to do what you bought these speakers for in the first place. However, if you wired them in a series resulting in 14c Ohms, it would decrease the available amount of power the receiver would be able to deliver to these speakers. That's just the way amplifiers work. The higher the impedance, the fewer watts they will deliver.
>so i purchased a pair of 8ohm dj woofers< Just the woofers, or are you talking about a complete speaker with an enclosure? Do not assume that a pair of bare naked woofers will produce any bass at all. An enclosure is required. It is not just there for cosmetic purposes. I also question your choice of DJ speakers for this use, enclosure or no enclosure. Why didn't you just buy a conventional subwoofer like everyone else? There is a reason why these things are so popular. They have a built in amplifier and thus require no effort from your receiver's power amplifier. Even if you don't have a "sub out" on your receiver, many subwoofers come with speaker level inputs that you can simply hook up to the speaker outputs on the receiver. This kind of connection will also draw no power from your receiver despite being hooked up to the speaker outputs. It will sound a lot better than DJ speakers which are not exactly built for high fidelity sound - more for brute, large room filling power and they don't produce much deep bass either particularly when compared to a high quality subwoofer - it's more like boomy mid bass, the kind that makes people want to get up and shake their booty to - that's what DJs want. Were I you, I'd return these DJ woofers and buy a decent, conventional home audio subwoofer. You will get a lot better results and stand much less of a chance of blowing up your receiver.
