View Full Version : Good budget crossovers and tweeters
06-15-2010, 10:10 PM
i found a good mid driver that i'd like to use im just not sure about who makes good crossovers. this will be the first set ive put together myself so i dont know too many companies who make them. i also need a set of tweeters. i like music to be smooth and not harsh at allllll. ive actually heard a system with a 4" mid instead of a tweeter and it sounded so smooth i loved it. just to clue you in to my taste. Im on a budget so more pocket friendly things would be better but im open to anything. hit me up

Are you going to run an amp or off the HU also are you looking to go passive or active?
06-15-2010, 10:46 PM
im going to amp them. bout 75 @ 4. and to be honest, im not sure what the difference between active and passive is
06-15-2010, 10:52 PM
Active is crossing over your speakers electronically, through an amp or electronic crossover. Passive is using a crossover that doesn't require a power source, just a signal.
06-15-2010, 11:06 PM
well im using an amp. so i gess active?
06-15-2010, 11:25 PM
an amp is used in both set-ups the difference in active and passive is if you run passive you will need one amp 2channels active would be 2amps 2channels each and your crossover would be in between the HU and the amp and have it's own 12v power supply then each channel of the two amps would have a component on it tweeter to one channel mid to one and so on(also no need to use the crossover on the amp) passive is when the crossover is after the amp and only req. a 2channel amp to work properly (one tweeter and one mid per channel). If your somewhat new to this start with passive there's a lot to setting up an active system and getting it to sound good, passive is more plug and play.( and a lot less costly)

yea passive is what im after.lol. just like a typical component system you'd buy with my own pieces. so any ideas on good stuff?
06-15-2010, 11:39 PM
let me hit up the ebay real quick and see if there's anything good up there.

Ok type in crossover on ebay then go to the bottom of the first page there is a set of new cdt 2way passive crossovers for 39.99+free shipping those should do the job without breaking the bank.
06-15-2010, 11:48 PM
ok they look good. with a 4ohm tweeter and 4ohm mid hooked up, that one still creates a final output of 4 ohm? and any idea for tweeters?

you need to decide on the tweeter before you choose a crossover. each tweeter has a recommended range, and you want to make sure the crossover keeps the tweeter operating inside that range.
you also need to take the midrange location and response into consideration. you don't want to buy any random crossover and not account for the response of both the midrange and the tweeter.
example - if your midrange driver rolls off at 2kHz @30deg off-axis and your tweeter doesn't do well below 3kHz - you'll have a hole in your response.
start by sharing the make/model of the midrange woofer you've selected (links to specs would be appreciated).
then share your budget for both tweeter and crossover.
then determine what you want the crossover point to be - based on the response of the woofer.
next choose a tweeter that can play down to the desired crossover point.
finally, choose a crossover with the desired crossover point and slope (i.e. 12db/oct, 18db/oct, etc.)
to be cheap and easy, you could just run the midrange full range, and high pass the tweeter with a capacitor. this is what any normal coaxial speaker does, and if the midrange is mounted in the doors, off-axis, you don't need a low pass crossover on it anyway.
you can buy stand-alone tweeters with passive crossovers - MTX, Pioneer, etc. sells tweeters only.

ok well i think i mighta hit a snag cuz the drivers are found aren't "mids" there normal woofers, like house style woofers. also i learned they're 8 ohm, so im not sure if that creates issues. but anyways, here they are

are these drivers you currently own? you can use 8 ohm speakers in a car just fine, you just need a larger amp to run them - usually an amp that is bridged - then the speakers get half the bridged power (assuming bridged is rated at 4 ohms).
look here for some decent speakers at various prices:

one issue is their location. if you put them in the doors - they might not be properly treated for moisture. any speaker in your door will get wet. you can help that issue with some XTC foam baffles.

note that crossover frequencies are different for 4 ohm vs 8 ohm - so you need to do the calculations, maybe needing separate tweeter high pass and midrange low pass.

our you can just make your own. it's pretty simple to make a second order (12dB/oct) crossover network specific for your speakers and their impedance.

guys i really appreciate all the help but im on a modest budget and all this seems like alottawork to please an untrained ear. ive been looking at these components and think they may be a good option since they're complete, good quality, and in my budget. this is more manageable for me

go with Alpine Type-S over Rockford

they looked good but i was reading reviews and people said the tweeters were kinda harsh. so i was hesitant. also i saw these

i have the coaxial versions of these in my front doors now with no complaints. think it would make any difference going to the same model component set?

you need to listen to these speakers before you buy them. you're looking at standard brands any big box store will carry. get out there and listen!
06-17-2010, 08:04 PM
good point. but unfortunately, unless some of this **** is at best buy, i wont get the chance too. cuz i live in bum**** southern maryland and the nearest audio store is almost 3 hours away
06-17-2010, 09:49 PM
most of what you've described is at best buy. listen to what they have and buy what you like from them. you get a warranty that way.
