What is a speaker crossover??

« on: February 26, 2004, 08:22:46 PM »

Hi everyone, Another question related to Audio not Video. What is a Speaker crossover?? I think but not sure it\'s something that goes into a speaker. I think a search on radioshack.com to get a price for it but it came up as a crossover cable for Networking which network is related to computers not Audio. Does anyone know about this?? I\'m not looking for a cable. If anyone knows about this, could someone tell me what exacly it is and where to purchase it?? I live in the USA so i need a store something like radioshack, bestbuy, kmart, walmart and maybe a few others.. Thanx guys..

It breaks the audio frequency up into low, mid, and high range. Thus the various broken up frequencies would go to different types of speakers specificly tweaked to operate at that range. Like tweeters and woofers for example.

I would have picked Radioshack as my first place to find one but you could probably find one at most larger audio shops like circuit city or something.

Also.....

There are different types. The standard crossover is usually built into the average larger speaker. The other type is an active crossover which is is a separate elecronic unit.

3 possible ways to handle this....

1) Buy a crossover. I have no idea what they will cost. An active unit will most likely cost you a bit though.

2) Go to the local flea market, find an old large speaker that contains the tweeter/mid/woofer. Spend the $10 or so. Crack it open, cut the darn wires to each speaker. The input will be the jack/clips that are normally on the back of the speaker. The outputs will be the sets of wires that would normally go to each speaker. NO GUARANTEE THOUGH...some speakers are cheapo and may not even have the crossover in them.

3) Find a crossover design on the web and build your own.

A crossover actually refers to one of several items or combination of items that cause audio signals to be blocked or allowed to pass based on their frequency.

A high-pass crossover is usually a simple capacitor that, based on it\'s meansurement, will only allow frequencies above a certain point to proceed, thus keeping out the mid and bass frequencies.

When using a low bass crossover, it mostly uses a coil instead of a capacitor to accomplish the same task of keeping higher freq\'s out and allowing the lower ones to pass.

As stated above, you have 2 options, passive or active. A passive crossover works well for passing an audio signal to tweeters, and a simple capacitor of the right frequency will do the trick. Active crossovers require a power supply and they tend to perform a better service ie better quality frequency filtering.

Are you trying to crossover home or car speakers? explain your needs more and we can point you more to your needs.
