Star quad cables might have a slight advantage in noise rejection in a balanced interconnect configuration, but it would be very slight. Where speaker cables are concerned they won't sound any...

If the wire is of insufficient size it can be heard, but bi-wiring won't fix that, as it doesn't lower the wire DC resistance where it's needed, going to the woofer. Where safety is concerned that...

Power handling isn't the issue so much as the cone excursion, which doubles with every 6dB of EQ.

The tweeter draws 10% or less of the total current. If the wire gauge is insufficient separately wiring the tweeter will make no audible difference.

What matters is the distance from the baffle to the wall. If that's 1/4 wavelength the reflected wave off the wall will cancel the front wave, causing a response dip. With an 80 Hz crossover that...

Triple the budget. Decent speakers will cost at least $300 each, and then you need to power them.

You don't need anything under a sub unless it moves about. If it does a rubber pad can help with that on a hard floor, spikes can help with a carpeted floor.

Using pro sound drivers 98dB sensitivity is likely, but not with useful 20Hz response. About the best you'll get at 20Hz is 85dB sensitivity.
This is the same nonsense that Zu has long spouted,...

That's a bit restrictive, a more common figure is 70%, so to qualify for an 8 ohm rating would require no less than a 5.6 ohm minimum. Either way, 4.8 ohms isn't even close. Klipsch hedges its bets...

Power density decreases by 3dB with each doubling of frequency, so if for instance you're running a 200w midbass down to 100Hz you'll have 100w at 200Hz, 50w at 400Hz, etc.

dBA is worthless, it only measures midrange. No weighting is best, but at the least you need to use dBC.
