Passive crossover vs. no crossover?

[Armstrong55]

I recently bought a set of Hivi speakers that came with tweeters and a pair of passive crossovers. I'm just wondering, would if make a difference if I do install the crossovers as if i didn't install them? Would it make it sound different or even make a difference in anything noticeable? Thanks.

Are you running an active setup?

If no then yes of course it would make a difference, it would sound like **** right up until the point that the tweeters blew.

Why do you think they included the crossovers? For no reason at all?

Like a noticeable difference as in making it sound a lot better?

A crossover is a frequency divider, so it splits up the frequencies being routed to the drivers. High frequencies to the tweeters and low frequencies to the woofer. Without the crossover, you will have constructive and destructive interference between the drivers as the wavefronts leave the membranes. This includes comb filtering in the overlap region and will lead to horrible behavior in the frequency response and also destroy the imaging potential. Lastly, you will not have proper protection from low frequency content entering the high frequency drivers. These are not built for excursion or efficient long-term thermal dissipation and will most certainly result in a quick death.

If you're not dividing the frequencies electronically with your head unit or amplifier, you will need the passives in place.

So i hooked the crossover up, but now my amp is blowing the fuse instantly

Done with the stupid **** and smart ***** like "ilikeradios" how about you help other than be a little prick. Got it all hooked up, drive maybe 2 minutes and everything quits working. Unhooked everything from amplifier and it continues to go into protection mode. any ideas

Could be a number of things. The fets inside the amp went out. Your wiring is too small.

The power/ground wire....even if it was 1 strand, are touching. Lose connection, something isn't tight.

Ground isn't secure enough, also could be a lose connection.

Wiring the amp at a low ohm, the amp cannot handle.

How about you try and not be such a sensitive little snowflake?

My answer was helpful.

I said unless you are running an active setup then you will blow your tweeters without a crossover.

That is a very direct and helpful answer.
