Product Details

Eminence PXB:250 Low Pass Crossover Board 250 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. In every way, Eminence pxb crossovers are a technically superior product. The 250 Hz low pass frequency is based on an 8 ohm driver. With a 4 ohm driver, the crossover frequency will be approximately 125 Hz. Dimensions: 5-1/2" L x 3-3/4" W x 1-1/2" H.

Rated 5 out of 5 by from Awsome product!!!I built a "bandpass" sub enclosure, but I needed the right "low-pass" passive crossover frequency in the unit I made? This Eminence product provided just that!

Rated 4 out of 5 by from Good Quality X-Over.I am an avid Eminence parts user and I find most of their products excellent, with quality.I find that the "T.I" brand capacitors are......okay. I wouldn't trust them for longevity. But, I have not had one fail. I would NOT power these more than they are rated. Common sense.Once again, Eminence has done well. GO FOR IT!!!!

Rated 5 out of 5 by from y2papoI purchased my first pair for home made sub boxes tuned to 20 hz. about 4 years ago and never looked back. They are phenomenal. I am purchasing one more at 250 hz cut-off for a 24"h x 24"d x 21" w vented box with a 15 inch peavey 3200 watt peak low rider sub. I will be pushing 800 watts rms with a qsc rmx 2450. although the amp can push to 1500 rms bridged at 8 ohms, I will follow the spec. from the sub manufacturer. My freind has this sam configuration and parts. The quality and presence this configuration is absolutely heart pounding and articulately low down to lower than 25 hz. Although the crossover is for 600 watts rms, it handles the 800 with no problem. Great product and actually better than advertised. P.E. will always be my choice for top of the line product purchase for speaker building.

Eminence PXB:250 Low Pass Crossover Board 250 Hz

How much will it affect the load that the amplifier is seeing? Will it add an additional 1 ohm per say? Meaning is the amplifier is driving a 4 ohm sub alone will adding this passive crossover increase the resistance to 5 ohm?

Asked by: Malek
The load is determined by the DCR of the coil itself. In most cases the DCR on a coil like this will be negligible at most and might add a half ohm to the overall load. This will make basically no difference in amplifier output power.

Hello, from what I been reading on here. It seems that I can use these in a double woofer cabinet with 8 ohms woofers. The end result would be 125Hz  4 ohms. Am I correct?

Asked by: kidgravity
Yes, at 8 ohm the low pass is 250Hz. At 4 ohm it will be 125Hz.

Can this crossover be used with a DVC sub woofer by connecting the outputs in parallel? That is, the positive output feeds both positive sides on the woofer and the same with the negative output.

Asked by: axeccn
Yes that will work fine, however the crossover point will change depending on impedance. The 250 Hz value is for an 8 ohm load. If it is 4 ohms it will double, if it is 16 it will be cut in half.

Can this be used with 4 ohm drivers?

Asked by: padenski
RussR was totally wrong by the way, it was a simple mistake, he says that the resulting crossover would double in frequency, but in reality it would half when going from 8R to 4R. So 250Hz at 8R is 125Hz at 4R. Just check the math with an online calculator and that was the consensus.
