Eminence PX:BULB Replacement Tweeter Protection Lamp for Crossover

Eminence px/pxb crossovers feature advanced circuit design to both preserve the crossover and your high frequency drivers. The high-pass protection uses this custom-built tweeter protection lamp.It is very easy to notice the flashing of these fuses as they work to absorb transients which are not being delivered to the tweeters. 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. For use as a replacement on all Eminence px and pxb pro sound crossovers.

Eminence PX:BULB Replacement Tweeter Protection Lamp for Crossover
Eminence PX:BULB Replacement Tweeter Protection Lamp for Crossover is rated 4.5 out of 5 by 4.
Rated 3 out of 5 by from BulbsI didn't realize that these bulbs were soldered together. They still worked for my application.

Rated 5 out of 5 by from Saves your tweeters!I bought this to replace one which had blown. They do what you would expect a fuse to do and more. I placed the crossovers in my PA mains near the vent, where they are visible from the FOH mix position. It is very easy to notice the flashing of these fuses as they work to absorb transients which are not being delivered to the tweeters.Get these for your speakers, you will not be replacing any more tweeters.

Rated 5 out of 5 by from Worked just fine!Worked great for a replacement for my peavey sp2x speakers. They are a little different than the original sullvania sk3 bulbs since these are two bulbs soldered together and the sk3's were a single bulb. But they still work and fit just fine!

Will these work on vintage Bose 501 speakers?

Asked by: TomO
These lamp fuses are designed for very high power applications, usually in pro sound. They will probably not be very beneficial in a lower output home audio speaker like the Bose.

Does PE sell a socket for these fuse bulbs to sit in.... as the PRV passive crossovers do not use a bulb fuse

Asked by: DMSLV
Unfortunately we do not have sockets for these lamp fuses. They are generally soldered in line with the horns if there are no previsions for them in the crossovers.

will these bulbs give a higher output?

Ok I have the peavey ecs 3x crossover & use the 44xt horn driver 100 watts & the eminence delta 10" 350 watts. Will this protection bulb deliver more output from the crossover to the drivers? The present bulbs glow way too high & the drivers haven't started to get their rms power.
Asked by: CEE JAY
These will provide twice the power as the original bulb so technically yes they should allow for more output.

Will this be enough to protect my Selenium D220Ti drivers? I run a 24db active crossover to them. The D220Ti has an RMS rating of 80 watts.

Asked by: AGPSYS
This fuse is used in the Eminence passive crossover boards, and performs its function well. However, if you're using an active crossover, the D220Ti should not require a fuse so long as you keep the crossover frequency at 1500Hz or higher, and provide clean power of less than 120W maximum. If your D220Ti drivers are installed in a rental system or otherwise not always under your direct supervision, then this fuse should provide a reasonable measure of protection.
