I have some fancy new stereo speakers. I'd like to be as correct as possible when wiring them up, which has led to some possibly-unusual questions about speaker impedance. Halp! (Inside: Series or parallel?) [more inside]

Ever since the DVD age began, I've noticed that music and sound effects in movies are always WAY louder than the dialogue. It's really annoying. Will a properly configured surround sound system fix this? What is the right way to set up surround sound speakers? Are sound bars any good? [more inside]

How do I replace a blown woofer in a Spica TC-60
loudspeaker? The datasheet
is here. I am generally capable, but don't know anything about building/repairing speakers. Can I get away with replacing just the one? Is there any danger of damaging the crossover (whatever that is)? The very nice guy from Madisound
recommended a ScanSpeak replacement
but how do I know if it will fit and/or work properly? If I'm reading the datasheet correctly, the original seems to be 180mm in diameter, and the replacement he recommended 170mm - is this a good idea? How can I tell if there's anything else I should try? What, if anything, do I seem to be overlooking? Thank you!

triple-flange sleeves work with Shure SCL2 earphones? If not, does anyone know of a third party vendor that makes compatible triple flange sleeves for the SCL2? I'm having a hard time getting any of the included sleeves to form a seal with my elfin ears.

I have a Tascam FW1082 midi/audio interface board. Over the last few months, there's been a more consistent and very loud high-pitched whine in the audio output, making it fairly useless for what I need. What should I do to get this fixed? [more inside]

I recently acquired an older reel-to-reel tape recorder, and it works fine except for inconsistent tape speed. I recorded a test tone and it plays back at a varying pitch. Can this be fixed, or should I put it out with the trash tomorrow? [more inside]

What is the best way to keep electronic devices that are in enclosed areas cool? (ie. stereo receiver, game console, etc).
I'm just got a new AV cabinet/stand that is a lot smaller than my previous one and my components are getting a lot warmer than they used to. My receiver has about 1" leeway on each side and about .5" on top. 1/3 of the rear of the cabinet is open. I also have my HTPC in there as well as my Xbox 360.
Anyone know of a simple way to keep them cooler (without adding noise or uglyness to my setup)? Would not like to cut anything.
Separate the exhaust and intake (so no hot air gets recycled) by blocking the sides and top at the rear of the unit.
Put a small computer fan at the back of the stand to improve airflow?
Put a exhaust hose (a la dryer) on the receiver where the fan is.. maybe put a fan at the end of the hose to pull more air through?
Any tried and true methods that arent too complicated?

Over the past several years, I have been burned by poor quality in home electronics from various manufacturers. I have purchased pieces by Sony (home stereo), Panasonic (theatre-in-a-box) and RCA (various pieces of junk), and all have given out in one way or another far too quickly for my liking. In a renewed attempt to build a proper home theatre system (DVD/CD, receiver, speakers, etc), and recognizing that I haven't the money for really high-end stuff but will avoid anything cheap, I seek outside opinions as to which manufacturers are making products that are of reasonable quality, and reasonably priced. Your experiences, please.

When I got home from work yesterday, my computer speakers were making an incredibly
horrible noise. When I unplugged them, the transformer was hot to the touch. There were storms in the area yesterday, although the surge protector plugged into the same outlet wasn't tripped and nothing else in the house seems to have been damaged. (The speakers were plugged directly into the wall, not the surge protector, because I had run out of room.)
So my question: would it be dangerous to plug them back in tonight and see if they're a lost cause? Should I just buy some new speakers and be done with it? (The speakers were expensive, but about 6 years old.)

I have an old Pair of Zenith Allegro speakers (50-watt, 8-ohm) with pre-attached cables and RCA-style plugs (male) for connecting to the stereo. I'd like to use them with a more modern receiver (50-watt max, 8-ohm) that accepts straight wire from the stereo; should I just lop off the ends and wire them in, or is there a better method? Also, can I use them with a >50-watt stereo if I keep the volume down, or is that just bad?
