800-5 kHz Band Pass 8 Ohm Crossover

Convenient crossovers that work great in any application requiring economical, flexible filtering. Also for use in car stereo installations with component speaker systems. Low pass, band pass, and high pass models complement woofers, midranges, and tweeters. Designed to be wired in-line between amp and speaker by using .205" disconnect terminals or soldering. The crossovers' compact size facilitates mounting virtually anywhere you desire.

Specifications: • Approximately 250 watts RMS • Type: Band pass • Driver impedance: 8 ohm • Crossover frequencies: 800 Hz-5 kHz • Roll off: 6 dB.

800-5 kHz Band Pass 8 Ohm Crossover
800-5 kHz Band Pass 8 Ohm Crossover is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Gets the job DoneNothing complicated. Installed in an old set of Peavey T-300 Model 1210TS PA Speakers on the 3 Piezo tweeters. Clear high sound. Big improvement. Assembly came out less expensive than buying parts separately.

Rated 5 out of 5 by from Good sound & build quality!worked really well for the my midrange in a 3 way horn loaded speaker system.

Rated 5 out of 5 by from Good productI asked one of the techs at parts-express why the horn driver for my homemade talk box kept failing.He replied (within 30 minutes) that I needed this crossover.I bought one and haven't had a problem since. Good product and GREAT technical service.

800-5 kHz Band Pass 8 Ohm Crossover

Hi, is there a way that i can change this from 6db to a 12db crossover? any help is greatly appreciated. thank you!

Asked by: customnewbie
Unfortunately there is no easy way to create a 12 dB crossover using this board. The values will need to be changed and two more components added in order to do this.

Is there a diagram for installing this crossover I could see? Thanx.

Asked by: geofed
Unfortunately there are no diagrams available. The side with the capacitor is the input side, the coil is the output. The terminals connected with the bottom trace are the negative and the other two are positive.

What value is capacitor would I need to have a 3k upper cutoff?

Is the 22mF cap for the low freq end of the crossover. Is there a second capacitor and if so what is the value of it that produces the 5k upper cutoff with an 8 ohm load? I plan to get the closest value capacitor to give me a 3K upper cut off frequency. Thanks
Asked by: Chris in Canada
The cap cuts off the lows and the inductor cuts off the highs. There is just the one cap.If you want to change the range to 800-3k, this requires an inductor change (actually both figuring a narrow bandpass).An 800-3k crossover can be made with a 18uf cap and .58mh inductor (narrow calculator).PE sells these parts. 255-040 and 027-346 will get you close for around the same price. All you need to do is wire them in series on the positive lead (terminal cup + to cap, out of cap to inductor, out of inductor to + terminal on driver).

Converting this 6db octave bandpass filter to a 12db octave bandpass filter?

I know I need another capacitor and coil but in what order would I solder these in? Also are the capacitors and coils going to be of the same values or different values? I have to make this a 12db bandpass, it's cutting my mid range by 25% being a 6db octave bandpass and it doesn't sound right to my ears. All my other filters (highpass and lowpass) are 12db and are only cutting the volume by 1/16 which to me is a big difference, my mid range is lacking the correct volume and it's a very efficient speaker.
Asked by: Harrison
The slope of the crossover will not help the difference in volume between the drivers. You need an L-pad to bring the overall volume down. I would recommend the one below assuming its an 8 ohm driver.

Why does this filter have a 6db roll off and not a 12db roll?

If my woofer filter has a 12db roll off, my midrange has a 6 db roll off, and my tweeter filter has a 12db roll off, all drivers are 8 ohms. How would this affect the sound of my set up? Wont this make my woofer and tweeter 2nd order and my mid range would be 1st order? I would just buy two 3 way 12db slope xovers but for my application I'm putting them in it would not work with the amps I'm using.
Asked by: Harrison
There are two issues here. What impedance will the amplifier see? This depends on the sum total of all the impedances of all the crossover sections and all of the drivers for the full frequency range. If that is acceptable, then go to step two.This filter has a 6 db roll-off because it is a first order filter. There is nothing more to it than that. It also means that it will have a specific phase alignment that, combined with driver placement issues and driver characteristics, may be either good or bad for the sound of your speaker. I can't say for sure which without actually engineering the thing for you.

Hooking this up in conjunction with another passive crossover?

I have a 2-way passive setup that I would like to convert to a 3-way passive setup using this bandpass crossover. My 2-way is 4ohm (drivers and crossover) and have a 4 channel amp. I would like 2 channels to drive this crossover to a Dayton 8ohm dome mid and my HP 4ohm crossover at 5k+ to the SAME amp channel. Is this possible? Or by having this bandpass crossover and a 4ohm HP crossover screw things up on the same amp channels? The other 2 amp channels would go to some woofers below 500hz crossed over actively. So, in sum, I'm trying to run 4 amp channels to do a 3-way setup with a mix of 4ohm and the mids at 8ohm with this crossover. Must I do 6 channels of amp to do what i want to do?
Asked by: jjohn
The primary issue, as far as the amp is concerned is impedence. This is a 1st order bandpass filter.A standard paralell crossover is equivalent, if not identical, to multiple LP, BP and HP filters. As long as the total impedance at all frequencies is acceptable then the amplifier is happy. Now the frequency response of each crossover section, in parallel crossovers, is dependent only on the load, ie the speaker. So as long as each section is loaded by its rated load then it should behave reasonably. The science involved here is circuit analysis which tells you how to subdivide circuits until it becomes obvious what it does.
