    Posted: 17 March 2017 at 12:54am


I bought 2 new 3 way crossovers for my speaker set. I wired the woofer to the W+ W - of the crossover as well as the tweeter to the T+ T- and the mid range to the H+ H-.(the pos and neg terminals on the crossover are in this order, HH,TT,WW). The woofer and tweeter sound perfect and are loud in volume, the 10" woofer im using as a midrange is very low and faint in volume(but sounded far louder when wired to Midrange of my older crossover). What does H H mean on a 3 way crossover?, is it for midrange or ? I did a test and wired the tweeter to the H H, and the volume was also very low and faint but loud on T T, anyone have an idea why? What does H H stand for? Cant find answer on google search. Heres the specs for the crossovers-3-way passive crossover 8 ohm Woofer Frequency: 20Hz-500HzMidrange - 500HZ-4.5KHZTweeter - 4.5KHZ-20KHZ600 watts RMS/1200 watts peak each

^Above is the crossover. Cant find pix of back and dont have camera. I wonder if this new crossover is defective or the H H terminal is 3/4 burnt out? Or is that the way H H is supposed to sound-its very low in volume and faint when mid or tweeter is wired to it and wat does h h stand for? if anyone has an idea, thanks.

stick the mid driver on it for testing and figure it out ? less likely to damage it . No idea , perhaps means something in another language ? ... If you read them upside down it could almost read M L H ?

Yes, swap mid and top (tweeter to H and mid to T) and see what happens.

Yes i switched mid range with tweeter(wired mid range to T+T- and tweeter to H+H-) and the mid range sounds much louder and tweeters very low in volume, this proves its not my midrange speaker but the H H thats sending very low volume. The h h of this crossover may be faulty or 3/4 burnt out. AND by the pix and specs of this crossover pair, are they 8 ohms each or 4 ohms? and is it 6 db or 12 db?

Not sure if this is helpful but the U.K convention colour coding for wiring signal from crossover to amp racks is

Red = Low
Yellow =Low Mid
Green = High Mid
Blue = High

What about the frequencies? Can you notice the different bands? Do they sound right? Maybe you should just send the xover back and get your money back.

The blue wire as picture of crossovers show is wired to H, which is supposed to be mid, but as you pointed out blue is for highs. I did contact seller and he said H H is for high midrange, T T is for tweeter. The freqs for W and T sound perfect, for H it sounds good on mid range but very faint, H wired to tweeter sounds slightly higher pitched than when tweeter is wired to T but very faint. TO MAKE MATTERS WORSE the white retangular item on crossovers get extremely hot like its ready to burn. It must be faulty, time to ask for a refund.

That is a 20W ceramic resistor and will get hot under normal use, but yes, no point messing around, just get a refund.
