## Description

Specifications:1)Size: 7*5*2.5cm (LWH)2)Suitable for Speaker Power: 400W or lower3)Suitable for Speaker Impedance: 4 to 16 ohmWith 4 jumpers onboard to optimize your audio effect: Jumper A, B for bass; Jumper C, D for treble.Details about jumpers:Jumper A, B are used to control audio effect of bass range. A for lower limit while B for upper limit of the bass audio range. For some speakers, when Bass is turned up too much, the speaker will show distortion. When that happens: we remove the jumper cap of jumper A to limit super low Bass to bring distortion lower. When we remove the cap of jumper B, Bass is increased while cap of Jumper B is on, Bass is decreased. Jumper C and D are used to control Treble range. When cap of both jumper C and D are on, the sound of treble is loudest. When only cap C is on, the treble sound is lower. When only cap D is on, further lower. When both caps of C and D are removed, there is no treble sound. (Generally speaking, with the four jumpers, you'd sooner or later find your best sound effect. Anyway, all effects still depend on your actual test.)How to use the splitter board:First connect as per our diagram above (Treble, Low, Input), connect to speaker, seal air gap, we can begin to hear music while optimize.Normally we use jumper A and let B idle. For jumper C and D: we need to hear the actual effect of treble. A general formula is: A+D=better Bass; A+C=clear Treble and Bass; A+CD=clear Treble and Bass (the overall effect inclined towards Treble); AB+CD=more mediant frequency. When Bass effect is unnecessarily high, we can remove cap A. Please optimize until you think the sound is best, and then fix the board with your speaker unit.Package included:4 x Crossover Filters 400W

Review: I replaced the 'crossovers' in ancient 1970's era Realistic Nova 5 speakers with these -clearly a big upgrade! (Was also replacing the woofers with GRS 8PR-8's since originals had surround foam failure) My ACEIRMC crossovers have the same model# YLY-2088, but are different than what's pictured here. Mine have the input on one end the the outputs on the other end... Also no instructions available for what the 4 (all closed circuit by default) AB(bass) and CD(treble) jumpers on the boards do. I've noticed that there several other sellers with this same model# crossover, so will look for more info there. And as noted below, I took the jumper off B on 1 crossover, and that speaker sounded better than the other where I hadn't done that.
Review: Built sturdy enough, are compact they they do work to clean up a 2-way speaker. Tested it, and it is a first order / 6 db roll off design. However, you'll get no specifics provided (no package insert / spec sheet) so you don't know what the crossover frequencies selected actually are. You play with the little caps, and Just have to judge by listening / by ear. Which is kind of a pain because it's mounted inside a box, of course. The inductor coil is in the signal path for the "bass" output, and gives a 6db roll off around 4000 Hz. On the high side. The tall blue capacitor in the path of the "bass" output seems to serve as a high-pass filter to eliminate deep bass rumbles (6DB roll off at 200Hz) and only kicks in when cap "A" is removed, otherwise it's out of the loop. It would be good use for smaller speakers or surround speakers. I don't know what the heck the idea was with with jumper B - if left on, it appears that full range goes to your woofer, though, resulting possible midrange mud, defeating the purpose of the crossover. The high-pass side for "treble" outputs have 2 capacitors (1.5 and 3.3 uF in black) that work either alone or in parallel, depending on the how the 2 jumpers are used, thus allowing adjustment of treble cutoff, which was noticeable by ear easily enough. Neat ideas for some flexibility and put into a neat, inexpensive little package, but complicated-ish and without proper documentation.
