i've been reading through some old posts and there are two things i do not understand. these things are inspired by things that whiterabbit and ludlemtheory said.

whiterabbit
what actually is the difference between mono and bridged. doesn't bridging make the ohms half to the amp and does mono do that do. if i had an amp that was stable at 4ohm in 4 channel, would it be stable at 2ohm mono or 8 ohm mono.

ludlem
i know that speaker freq response is important to how the speakers sound. you siad before that kappas don't play anythign below 200hz. but their response is well below that, how does that work. if most speakers have similar repsonses what determine what speakers sound better.

thanks

Mono of course means one and bridged is the process of wiring 2 channels to function as one. Mono could refer to a monoblock (1 channel) amp, or it could refer to an amp that is running bridged mono. This would most likely be a 2 channel amp, as with a 4 chan, you could still have left and right or front and rear so I'm not sure if you could apply the term mono there. If you have an amp that is 4 ohm stable, then it cannot be bridged unless you have at least an 8 ohm speaker load on it, as putting a 4 ohm speaker load on it will cause the amp to see a 2 ohm load which it is not able to do.

and speaker design is what determines how speakers sound, not the range of frequencies that they are able to respond at. *most* speakers of similar size will have similar frequency respose with some variation of course, but you need to use crossovers to limit them to a certain range for your application. Just because the Kappa's could play down to 20hz doesn't mean they should. They should play to about 80hz (assuming these are midbass speakers) and the subs can take care of the 20-80 range.

well, how do you know the amp would not be stable if you don't what amp it is.l aren't some amps more stable than others? could you bridge a 4 channel to mono?

If you don't know the amp specs you don't really have a way of knowing how stable it is without testing. Yes some amps are more stable than others. I'm not sure if you could really bridge 4 channels into 1, but probably.
