Parts Express 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.

I have a 8ohm woofer and and want it to be 4ohm will this bring down the resistance and keep the crossover frequency 

Asked by: DJFresh1997
Unfortunately no, there is no way to change the impedance of a specific woofer.

I have four Boston Pro Series 50SE 5-1/4" drivers at 3 ohms each. I need a 12db slope at about 80 Hz for one pair so I can augment bass from 60-120Hz in a very damped car (the BA's are in small custom enclosures). Which 4 ohm LP x-over gets me closest?

Asked by: Lee_AV
These filters will be the closest to that figure.

I have some marathon 2x18 subwoofer rated at 4800 watts max (I dont believe it's true though). It doesn't hit hard as I think it should. I'm thinking of adding these crossovers to them before scrapping them. Will this give them better lows.

Asked by: kidgravity
This depends on too many variables to give you a solid answer unfortunately. If the subwoofers are crossed over much higher or playing full range, this will certainly make them sound cleaner as a subwoofer.

How will this affect speaker power output? I have 91db full range speakers and will be adding a 91db sub woofer. I don't have the ability to control volume independently on full range or sub. Will the sub have lower volume? Will I need to add an L-pad?

Asked by: eddchavez
This low pass filter, like all passive crossovers in all speaker systems, will create a -3 dB power loss between the amplifier and speaker. Since all of your speakers suffer the same insertion loss from their crossover networks, you will not notice a loss in sensitivity (how loudly it plays). This does not necessarily mean that you won't want to turn the subwoofer up or down once in use. An L-pad will allow you to turn it down, but of course not up. That would require a subwoofer amplifier.

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.
