Product Details

80 Hz Low Pass 4 Ohm Crossover

Convenient crossovers that work great in any application requiring economical and 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: Low pass • Driver impedance: 4 ohm • Crossover frequency: 80 Hz • Roll off: 12 dB.

Note: Our current inventory is labeled as an 80 Hz high pass filter, with phase reversed on the input side. This crossover will perform as advertised if you swap the positive and negative connections on the input. The output side of the crossover is not affected.

How to use with a subwoofer?

I have a 4 ohm 8" subwoofer driven by a 4 ohm 100w amp. Would this be the best crossover to block out the high frequencies? Someone had recommended not to let anything higher than 40hz go to the sub woofer.
Asked by: bmunger
This will work well with what you have, don't worry about a 40hz crossover 80hz is the standard crossover frequency for subwoofers.As for how to use you just wire it inline between your amp and subwoofer, it should be marked for +/- in and out.

Is this what I need??

I'm building some towers with passive subs in each one. The sub drivers are 4ohm, and the towers' impedance is 8ohm. Is this the appropriate filter to use or will its impedance cause problems with the 8ohm impedance of the towers after the inline sub? Or, should I opt for 8ohm subs and filters instead?
Asked by: OHMN
This will affect overall system impedance and your amplifier will see something close to a 2-3 ohm load overall which is generally not recommended. If you use 8 ohm sub drivers with the 8 ohm filter, your overall impedance will be 4 ohm which may or may not be good for the amplifier, you will have to check the manufacture specs.

2 subs in 1

I am in the planning and pricing phase of a project. I Want to build a sealed 10" sub and and a ported 10" (rss265HO) sub in the same outer box. I was planning on using the dayton Spa 1000 setting the x-over at about 150 hz then dividing that signal up so 150-80 ( high pass at 80 hz) goes to sealed enclosure and sub 80 to ported will this handel that power.do i need to put 2 in parallel
Asked by: Dominic
This will work for your application, since the drivers will be wired in series you will be right at the RMS power limit of the crossovers so you should be fine.

I have a 6Ohm and 4Ohm box in parralel, this gives me a 5Ohm load i think. Is a 4Ohm low pas filter then ok for me?

Asked by: fredje81
Actually a 6 ohm and 4 ohm load in parallel will yield closer to a 3 ohm overall load. A 4 ohm crossover will work but the crossover point will change slightly, in this case go up a bit.

4 Ohm or 8 Ohm

Hi I Have two (2) 10" 4 ohm single voice coil sub-woofers that are wired in parallel. Which crossover(s) would be best for me a 4 Ohmor 8 Ohm Low Pass Crossoverhttp://www.parts-express.com/pe/showdetl.cfm?PartNumber=266-442Or Should I go with one of these?http://www.parts-express.com/pe/showdetl.cfm?Partnumber=260-221
Asked by: Brutally Honest Mike
Your two 4 ohm subs wired in parallel will present a 2 ohm load to the crossover (and the amplifier). We do not have any prefabricated filters for 2 ohm speakers, however, a 2 ohm load will shift the crossover frequency down by approximately one octave on a 4 ohm filter. So, for example, using your 2 ohm situation on a 4 ohm crossover, if you wanted a 100Hz low pass, you would use a 200Hz 4 ohm filter. Your other option would be to wire the subwoofers in series to achieve an 8 ohm load, then simply choose the appropriate filter for that 8 ohm load.
