Eminence PX:BULB Replacement Tweeter Protection Lamp for Crossover
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.
I have used this fuse in exactly the application in which you are. The fuse protects the Selenium fine.I mounted the crossover near the port in the cabinet so it is visible when the system is in operation. This way you can visibly monitor the power being applied to the tweeter and change the fuse if it blows. The lamp begins flashing as excess power is shunted away from the Selenium. If one of the lamps suddenly stops flashing you know you have blown the fuse and to turn down the volume.More than one person has asked about the flashing lights in my cabinets.

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.
Most sound reinforcement drivers come with an RMS and music program power rating. The music program power rating is generally much higher than the RMS rating.I have used these in sound reinforcement conditions in which the high frequency driver has a 80 watt rating. This driver is crossed over slightly higher than the manufacturer's recommendation based on the our analysis of the drivers response curve when coupled with the horn we use. The cabinet in which this fuse is used is powered by a Crown XLS802 which outputs considerably more than the high freq. driver is rated for.Since beginning to use this fuse we have not experienced a single high freq. driver failure, period. We have had to replace one fuse when an amp lost a channel and DC'd the drivers.While it is never a good idea to exceed the manufacturers recommended power rating for a given driver, from our personal experience this fuse allows you some latitude in powering your high freq. driver.The passive crossover in each cabinet is mounted near the vent in the cabinet. I have watched these fuses blinking in time with the music all night long as they absorbed the excess power being delivered to the high freq. driver.The Eminence literature for this fuse says it acts as a 3-1 analog compressor. From my experience this fuse does work as advertised.Below I have shown the high frequency driver and the fuse we use in the product recommendation area.Good luck!

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