Do I need a crossover with these?

I heard these have a built in crossover. Is this true or do I need a crossover?

Looking at the picture of the components looks like there is a small crossover built onto the mid-woofer near the speaker terminals. Every component system I've ever seen comes with passive crossovers. So looks like you're good.

 

That's not a crossover - it's a .15 mH inductor coil to keep the woofer from playing higher frequencies (only one component of a passive crossover). You'd want a capacitor for the tweeters as well - maybe included? If not, you'd need to calculate the desired rolloff point (or consult a chart) and install caps also. May need a resistor(s) or L-pad as well as I suspect they'll overpower the woofers if fed the same power. Alpine may provide more info?

 

They come with crossovers

 

Ok maybe I don't want these then. I'm looking for something easy to install.

I read somewhere that the crossover is built into the speaker ?

 

The crossover is pre-wired between the speaker and the tweeter. It fits nicely behind the stock tweeter mount on 2nd. Gens. If you want something easy, stay away from anything that says "component speakers", stick with 2-way or 3-way speakers. They have built-in crossovers.

 

Aren't these component 2 way speakers ?

 

These are both Alpines. The first photo is 2-ways with the tweeter mounted in the middle of the big speaker. The second is components. The black tubes are the crossovers.

 

In reality components need more than just a crossover for the tweeter. You should have a low pass for the woofer to help out with the imaging. With out it the woofers play to high of a frequency and pulls the staging down to your knees not up front where it should be . The first set I would not use period. It may play louder but used with the OE tweeters gives you way to much high range which will cost you imaging being one set is down low. Only one set of tweeters per car works best

 

Looks like you don't need to. I just poked around the Q/A on Amazon for the same part number.

 

Cute yeahh use crossover. Just get coaxial stop crying

 

If they're built in there's no need to add one.

 

Find a good set of components with a passive crossover that divides the frequency between the woofer and the tweeter. That puts the woofer down low where it don't hurt and the tweeter up higher where they should be and only two tweeters not 4. Toyota could of thrown a cheap coaxial in the door and called it good for less time and money than what they did spend. Don't change things just to say you changed something . At least attempt to improve upon what you have to start with not just more sound. Simply taking the OE tweeters out and put a real set of tweeters in the sail panel will improve the sound of your existing set up . You can simply install a good two way crossover with the relocated tweeter and the OE woofer will make a hell of an improvement for next to nothing . Speaker location means much more than the average coaxial user knows, yet. Just my .02

 

Wrong. A inductor coil is a 6db crossover. All tweeters must have crossovers otherwise they'll almost immediately fry. Rarely will a resistor be needed to avoid overwhelming mids but a lot of that depends on mid and tweeter design and quantity of mids vs quantity of tweeters.

 

You're obviously experienced in the field. However the necessity of a crossover is only necessitated by the mid range speaker itself as many mid range speakers simply will not play those high frequencies you're referring to, depends completely on the speaker in question. If the speaker won't play it then it's a non factor. I personally have combined stock tweeters with aftermarket mids many times with excellent results, it just depends on the mids design and the tweeters design. As far as only using 1 set of tweeters that is completely false, it's all about the system be designed to work together. For imaging purposes it's best to mount the tweeters high and within 1 foot of the mid, you want the mids no higher than ear level (pretty easy in a vehicle lol), and the woofers as far away as possible with the sound bouncing off of a panel as much as possible. It takes distance to produce low frequency sound waves. A 20 hz note takes 20' to fully develop so the further away the woofer is and the more the sound waves bounce around before reaching your ears the more of the bass frequencies you'll be able to hear inside the cab. 20 hz is the lowest frequency a human ear can hear.

 

Installation of component speakers (separate mids and tweets) is just as easy as installing 4 speakers vs 2 speakers. Component speakers will always sound better than 2 or 3 way speakers because 2 and 3 way speakers block part of the mid range speaker. Pretty basic information on components vs coaxial and triaxial.

 

Put tweeter in the a panel

 

A pillar

 

To each their own but I definitely wouldn't recommend the A pillar in a Tacoma. The A pillar is far too far from the mid speaker and the separation of the two in that distance will be audible and less desirable than if the tweeter were mounted closer to the mid. I personally prefer the tweeter mounted in the door as far forward as possible and about 1' higher than the mid. Make sure the location you pick that the door can still be shut and that the tweeter won't hit the dash (you'd be surprised, lol). Too much distance between mids and highs WILL BE audible. Of course a lot depends on the type of music you listen to.

 

Getting a little picky with the semantics aren't we? An inductor coil in series by itself is used as a low pass filter - or a component in a crossover. It's used to prevent a driver from playing higher frequencies. A capacitor, when used in a similar manner, is used as a high pass filter. You will find them separately and together - depending on design. Collectively, on a board, in a case, with resistors and terminals, are typically called the crossover.
