800 Hz Low Pass 8 Ohm Crossover
800 Hz Low Pass 8 Ohm Crossover is rated 4.8 out of 5 by 5.
Rated 4 out of 5 by from 800 Hz Low Pass plus 800 Hz High Pass crossoverI score 4 stars to this product because I don't know whether I can have a better replacement. I got a pair of old speaker with altec 808a horns inside. It's build in with a radio shack 40-1299 3 way crossover. In order to make it better, I replace the high pass with the 800 Hz high pass crossover. After the replacement, I found that the difference is very little. As I don't want to make conclusion too early, I purchased the 800 Hz crossover also and replace the radio shack crossover with the 800Hz high and low pass crossover. After the replacement, I found that sound quality is much better especially for the vocal part. For my standard, the performance is good and I am very satisfy with this combination.

Rated 5 out of 5 by from Excellent and well built crossover.I purchased this crossover back in January. I have used it for probably 40 to 60 hours.The description states this is rated for 250Watts RMS, but for the 40 to 60 hours I've used it, I've been pushing 500Watts RMS through it and it never even feels warm.This is only a temporary setup for me, so I can't say it will last forever pushing twice its rated wattage, I also cant say if this is limiting the power going to the woofers attached to this, but for the few months I used it (until I built a passive Line Level crossover) it worked perfectly!

Rated 5 out of 5 by from worked like I expectedUsed To make the door speakers in my Saab into subwoofers to make it seem like it had more bass while in reality it just deleted everything else.

Rated 5 out of 5 by from Works well as it should.I used this in a custom horn loaded speaker system, worked really well! good overall construction, easy to use and does it job well.

Rated 5 out of 5 by from Works as advertisedI used this for re-building a woofer on a leslie speaker. Price was right, and the finished speaker sounds great.

800 Hz Low Pass 8 Ohm Crossover

How would you recommend mounting this for a car audio application? They will be on my rear shelf (metal with fabric panel overtop.). Thanks

Asked by: AmarGill
The easiest way would be to wrap cable ties around them since they don't have mounting holes. Velcro or strong double sided tape is another option, although a hot car will probably cause the adhesive to fail eventually.

Would this work on a 4ohm speaker?? I need to cross-over at around 400-500hz but you do not have a 4ohm available to crossover at that freq.??? I would build my own but do not know what size coils or resistors to use??

Asked by: djchino69
It will work with a 4 ohm driver but it will not cut the crossover frequency in half. I would recommend a 60 uF cap and 2.5 mH coil for a low pass at 400 Hz using a 4 ohm driver.

800hz

I have a goldwood GW-s525/8. It is an 8 ohm speaker but when using this low pass filter I can still reach over 4khz. How can I stop this? Or am I doing something wrong?
Asked by: buck3690
At 800Hz crossover, a 12 db. per octave roll off you will get minus 12 db at 1600 hz [about a notch below half volume]. At 3200 Hz you will get minus you get minus 24 db [about one quarter volume] At 6400 Hz you get minus 36 db [about one eighth volume]. So, a roll off filter does not eliminate the signal, it reduces it at it's the specified rate. This is to give you a smooth transition from bass to mid/tweet.You can still hear the 4khz at that rate. Now this is assuming that your inputs and outputs are correct. I have been known to reverse them. OOPS!

I want to 3D-print a Speaker Wire Terminal Plate and incorporate a mount for this x-over. Does anyone know the PCB dimentions of this x-over ?

I have ordered one but I would like to start on the build before it arrives.
Asked by: Triac
The PCB measures 4-3/4" L x1-7/8" W.

Asked by: f16voodoo1
Yes the board is labeled to show which is which.

mounting inside cabinet

I don't see any screw holes so how do you recommend mounting it? If glue what kind?
Asked by: KUL8D
You can drill through the board. I would put two holes somewhere around the large inductor. As long are you are mounting into wood or something none conductive, you should not have a problem with shorts from your mounting screws. If you are worried, make the hole have generous clearance from your screw and pick up some plastic washers. Then again, start with a bit larger than your screw head to remove the metal clad, then finish the hole with something a little larger than your thread diameter.I have mounted crossovers with hot glue (only on flat horizontal surfaces) and epoxy (mix it up) type glue on sides or the top.I have also fabricated a board to hold the crossover with scrap, cable ties, and hot glue, and then mounted the board to my box.I hope this helps and best of luck with your install.
