Product Details

Eminence PXB3:3K5 3-Way Speaker Crossover Board 500/3,500 Hz
Eminence pxb board-only crossovers are a lower cost alternative to the "cabinet ready" models and are targeted specifically for custom cabinet projects as they do not include the terminal cup, input connectors or L-pad found on the "cabinet ready" models. They feature advanced circuit design to both preserve the crossover and your drivers. A benefit of the design is to form a voltage divider across the high frequency driver. The high-pass protection uses custom-built aerospace lamps. The tungsten filaments effectively track the program material, dynamically maintaining a safe maximum current level to the high frequency driver without introducing distortion. This circuitry provides smooth 3:1 analog compression during input overload conditions over 250 watts RMS. At full drive level approaching clipping, the electrical attenuation to the protected high frequency driver is -4.5 dB. In every way, Eminence pxb crossovers are a technically superior product. For use with 8 ohm drivers.

Eminence PXB3:3K5 3-Way Speaker Crossover Board 500/3,500 Hz
Eminence PXB3:3K5 3-Way Speaker Crossover Board 500/3,500 Hz is rated 4.7273 out of 5 by 11.
Rated 5 out of 5 by from Worth their weight in gold.I built a PA system from scratch this past Summer. 4000 watts per side, with 9 drivers crossed over at 8 points. I ran this X-over in line with another from PE as well as an electronic X-over for subs. These cabs are 6'x2'x2'. The entire cab(s) are subs driven by 2 18s (each), with the mains built into the center front of the cabs. The mains house a 15, 12, 2x10s, 8, 2" mid high, and a high long throw horn. These cabs are also 'active'. The only way I could get a totally 'full' range system was to build it myself. It's awesome. But unfortunately, my mixing board turned out to be not so awesome. Last night during a rehearsal, a low to mid sweep pot shorted over and pumped the 3K to full on. The fuses in these X-overs lit so bright that they hurt our eyes. It took about 5 seconds to shut down. Not only did the fuses NOT blow, But BOTH pairs of horn drivers suffered ZERO damage. I still don't believe it.

Rated 5 out of 5 by from Great crossoverI purchased these crossovers 1 year ago and they simply over achieve. No issue's, they can take a tone of power (McIntosh MC 2500 500 watts) and sound like they were custom made for my speakers. I'm using a 2404 JBL tweeter, Beyma 6.5" mid with a Beyma12" woofer, no issue's no complaints. These speakers with those crossovers will satisfy even the most discriminating listener!

Rated 2 out of 5 by from Ok but...I bought this to replace my 30 year old DIY crossover thinking it would make my speakers sound better. Unfortunately, because the midrange on this design is only a 6db/octave slope instead of my current 12db/octave slope, it blew out my midrange within an hour. Ouch.

Rated 5 out of 5 by from Great replacement CrossoverThis crossover replaced a 3-way in an old Audio Centron cab that caught fire. Sounds great

Eminence PXB3:3K5 3-Way Speaker Crossover Board 500/3,500 Hz

I would like to know if possible the R.M.S power handling for the tweeter output on this crossover, the total power is 400 R.M.S but how much will the tweeter recieve until the bulb limits the power and how much until the bulb burns and neds replacement? 

Asked by: Criss
The crossover as a whole handles 400 watts. Each output does not have it's own rating and there is no exact science for figuring out how much power a tweeter receives through a crossover. Generally speaking a woofer will handle 80-90% of the power and the tweeter gets the rest.

If i use 8 ohms load in the 3 M, H and W i will get an 8 ohm impedance of the crossover? sorry i'm new and i wanna build a 3 way tower for my living room with 2-8" 4 ohm mid's , 2-Tw 4 ohm and 2- Woofer 4 ohm each tower

Asked by: Victormx
Yes if you use 8 ohm loads for all three drivers, the overall load to the amp will be 8 ohms.

Didn't ask my question completely. My cabs will have two EM-428's in parallel and one ET-338 (all morel). will this cross over handle this application ok.

Asked by: Porky
not recommended for 4 ohm loads. It will change the crossover point by half.

Each cabinet will have two Morel EM-428 mids in parallel. Is this xover good for this application?

Asked by: Porky
This crossover is intended to be used with 8 ohm loads for each driver so if the Morels are 8 ohm, you would need a crossover designed for 4ohm loads in the midrange

I've updated a 3 way sealed system with a Phenolic Ring Tweeter from PE and Visaton W300-8 12" drivers (mids say 1-4.5khz but may have been relpaced).  Currently only has resistors to the mid and tweeter. Would this be a good match?  (Box is 2'x13"x15")

Asked by: ioev
Without knowing which midrange is being used it is impossible to say. As long as it can handle a crossover of 500 Hz on the low end this should not be an issue.

Is it possible to get a four ohm load off this crossover so I can utilize higher output from my amplifier?  Thanks. 

Asked by: pikeaxe
The crossover itself does not determine impedance. If you were to use 4 ohm woofers you would get the full potential of a 4 ohm stable amplifier.
