Jbiddle530 Posted May 4, 2013 Report Share Posted May 4, 2013 so i have a custom 3 way speakers set but i dont have any crossovers. i am working on an sq system but i dont want to run active.. i know everyone is telling me active but its more hassle than i wanna deal with. i already have an old school eclipse premium 34230 amp which puts out 370w rms x2 @ 4 ohm which is more than enough for a nice 3 way componant set. i have dayton audio reference series 8" midbass 4 ohm Dayton audio reference series 6" midrange 4 ohm Vifa 1" silk dome tweeter 4 ohm what car audio 3 way crossovers do you guys know of that may wrok for me. i need a crossover that has a low tweeter crossover point below 2500 if at all possible. im wanting a midbass to midrange crossover around 350hz and a midrange to tweeter at about 2200hz but i know with something like this im probably gonna end up having custom ones made. but im hoping someone knows of premades that will work for me Link to comment Share on other sites More sharing options...
trumpet1 Posted May 5, 2013 Report Share Posted May 5, 2013 I don't know of any passive crossovers that will give you a low pass filter of 350 Hz. 1 kHz is doable with premade passives. However, this 350 Hz filter may be available on a different amplifier. You could set your filter on the 8" midbass by using an amplifier that has a high pass filter higher than the 200 Hz max of your 34230. There are good powerful 2-channel amps for under $150 that would do a fine job. For the mid/tweeter crossover it shouldn't be difficult to find 2-way passive crossovers that will cross them at 2.5 kHz or lower. Link to comment Share on other sites More sharing options...
SnowDrifter Posted May 5, 2013 Report Share Posted May 5, 2013 In all honesty: active is easier than trying to build a custom crossover.DD makes a nice crossover. All you need to do is hook it up, count the "clicks" to set your crossover point and you are good to go ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...

the moose Posted May 5, 2013 Report Share Posted May 5, 2013 I agree also, the 350hz cross over may be hard to find, a 250hz may be more common? Have you checked parts express.com, also check out the12volt.com for passive crossover charts will tell you which chokes, resistors,capacitors to use for building a crossover with either a 6, 12, or 18 db slope. Try to use tweeters with a higher spl than your other drivers. Well passive crossovers are easy and cheap to build either way...Good luck 1974 VW Beetle 2- JL Audio 10w08 subs in ported fiberglass enclosure Hifonics ZRXLP 6.5C (fronts) Hifonics HRC 5.2C (rears) 500w Crunch powerzone amp (subs) 600w Crunch powerone amp (components) 3 farad power acoustics cap. head unit- Planet Audio P385UA Boss eq 1208 Link to comment Share on other sites More sharing options...
Kevin M Posted May 5, 2013 Report Share Posted May 5, 2013 Active is easier than building a custom pair of x-overs for those particular speakers and your cars acoustics. 2 four channels can get you there and there alot that have bandpass capability. It will allow you to adjust the gains for each to help fine tune. If you want to go passive just call PE and they can build you a custom pair of crossovers. Depending on the components used and the slopes you may be looking at up to 200 bux anyway. You can get a ppi amp with bandpass capability, 24db slopes for around the same price. Then you could use the eclipse to power your midbass. Just something to think about. 2005 Ford Focus zx4 AMT's and Planars 18" Infinite baffle Link to comment Share on other sites More sharing options...
trumpet1 Posted May 5, 2013 Report Share Posted May 5, 2013 You can get a ppi amp with bandpass capability, 24db slopes for around the same price. Which amps are you thinking of? The current PPI amps have 12 dB slopes on the crossovers. Link to comment Share on other sites More sharing options...

The current PPI amps have 12 dB slopes on the crossovers. You're right. apologies. Thought they had steeper slopes.
