5 kHz High Pass 8 Ohm Crossover
Can you combine this with other PE crossovers to make a 2-way or 3-way setup??
Can you combine this crossover with other Parts Express passive crossovers of this type to make a 2 or 3 way setup? For example, this 5k HP, the 800hz-5k bandpass , and the 800hz LP? Are the inputs/outputs labeled on the back? If this will work, I assume the inputs would be in parallel if one had only 2 channels of amp? Or, there would be an option to bi-amp the above scenario too? For example, 6 channels of amp were available to drive each crossover in this same example. Please advise. You guys rock. Thanks!
These kinds of parts are designed for quick solutions. The more complex the system, the less ideal they become. Speakers need level controls to balance the tweeter and the woofer, or more, in the case of a 3-way ... this can be done with resistors or level controls which are easier. You can read a good article on PE under the SPEAKER BUILDING tab, and then in the right column - CROSSOVER BUILDING GUIDE. There are many "Crossover Calculators" where you can choose 3 or 3 way ... 6, 12, 18 or 24db./oct, and some even let you put in the drivers efficiency and then the resistors are factored into the design... As a novice - keep in mind that great speaker designers tune crossovers over many hours, days and weeks, and use sophisticated instruments... The easiest way to start and have some great success is with 6db/oct with level controls. Have fun.

Crossover needed for both drivers ?
I haver a generic 2 way pa cabinet with a 12" ans a compression horn driver. Do I need a cross over for both the 12" and the horn? I am sorry I cannot provide specifics on the drivers despite googling every number on them I can not find any info on them. These cabs are going to be used as monitors till I can afford to replace the speakers. I can tell you they are both 8 ohm and currently they are wired in parallel with no crossover. Someone before me tried to rewrite the speakers.Thanks in advance.
Someone made a mistake in rewiring them. You need a high-powered two way crossover for a PA speaker. You want the low frequencies to roll off from the tweeter to protect it. At the same time - you want the high frequencies of the woofer to roll off so neither driver is producing the same frequencies. You can get a board or a assembled connector dish you mount in the cabinet. 5000 seems a high point for a compression horn... I suggest search "crossovers" and check out these two part numbers:Eminence PXB2:3K5 2-Way Speaker Crossover Board 3,500 Hz Brand: Eminence Speaker | Model: PXB2:3K5 Part # 290-636 andEminence PX2:3K5 2-Way Speaker Crossover 3,500 HzBrand: Eminence Speaker | Model: PX2:3K5 Part # 290-622

conversion to low pass
i'm planning on buying a few of these & converting some of them to a low pass crossover since i can't find a matching one on the site. that way i'll have low-pass for the woofer & high-pass for the tweeter. seems a simple matter of some soldering skills. i could just buy a 2-way, but that's less fun and costs more. anyone have concerns?i haven't decided on which woofers to use below, but i'm leaning toward the Aura. this will be an in-wall experiment.thanks in advance, & i appreciate the vast wealth of knowledge on this site.
The parts for a low pass are different from a high pass so you can't convert these. You should consider buying some pre-made 2-way crossovers which are available in a variety of crossover ranges here at parts express. If you want to build custom - you can web search "speaker crossover calculator". It will ask the impedance, crossover frequencey, and type of crossover you want (6,12,18, 24 db/oct rolloff)... Hit enter and a diagram will show the design and list all the parts.

I have a really compact build im doing and i NEED to know if these will fit. Looks kind of long, and if its anything like the 800 high pass i got, then it wont fit. Anyway you can put up the size for these?
Figure about 3" max. You can always buy the parts yourself and lay them out differently to fit your application.

Can you please tell me the dimensions of this crossover?
This board measures 4" long, 1" wide and 3/4" tall at the highest point.

Don't you only need a capacitor for a high band pass for tweeter?
It looks like an inductor as well attached to the cap. Why?
When referring to a high pass filter, a single capacitor in the positive signal path is a first order (6dB) high pass crossover. When you add an appropriate inductor across both terminals, it becomes a second order (12dB) affair. 1 cap + 1 inductor = 2nd order; another cap makes it 3rd order, another inductor is 4th, and so forth (pardon the pun) and so on. As the order of the crossover (by the corresponding number of components) is increased, the slope of the rolloff as viewed in a frequency response graph becomes steeper. In our example case of a high pass filter, less low frequency is allowed to pass to the tweeter as you increase the slope (or order) of the crossover. For low pass filters, the cap and inductor are reversed, but the nomenclature for slope remains the same. For more information, follow the link below to our Technical Help page. Crossover theory is covered to some extent in the top section, under the heading of Speaker Building.http://www.parts-express.com/techHelp.cfm
