Passive Crossovers
 
PART# 
 
   
 
 
Our line of high-pass tweeter crossovers pass only sounds above a particular frequency. Their very steep 18 dB per octave slope provides for very accurate sound reproduction, high power handling capabilities and prevents low frequencies at high volume from harming the tweeter.

• 3rd order, 18 dB per octave crossover for sharp tweeter response
• Easily handles up to 200 watts of power.
• The sharp roll-off protects the tweeter from excessive levels of low frequency
• Models available for 4 ohm and 8 ohm tweeters.
• Encased in shrink tube with wire leads for easy installation.
• Individually packaged.

Bass Blockers remove or ' cut out' sounds that are below a certain frequency. They are designed to enhance the performance and power handling of tweeters and midrange speakers by removing frequencies beyond their capabilities.

•Easily handles pwer of up to 50 watts
• Leads are color coded to prevent misapplication
•Encased in shrink tube with wire leads for easy installation.

Band-pass crossovers utilize a 2nd order, 12 dB per octave slope for clean reproduction of the passing frequencies. The Band-pass crossovers are mono - one is required for each channel.

Part# Bandpass Point
BP24 Passes between 100-300 Hz for 4 ohm speakers.
BP28 Passes between 100-300 Hz for 8 ohm speakers.

Power resistors allow you to increase resistance to particular speakers to reduce signal volume. Reducing signal volume of tweeters, rear fill, center channel or other small speakers is a very easy way to produce a better balanced system.

• Can be used individually or in any combination to develop almost any desired resistance
• Capable of handling 50 watts of speaker input

Part # Description
R1 1 Ohm resistance
R2 2 Ohm resistance
R4 4 Ohm resistance
R6 6 Ohm resistance
R8 8 Ohm resistance
POT 50K 0-50k ohm adjustable, audio tapered, dual potentiometer (not shown). For RCA level signal.

Tweeter protectors are poly switches, which drawmatically increase resistance when power input to the tweeter rises to an unsafe level. The fast increase in resistance shuts down the power to the tweeter, protecting it against excessive power. Tweeter protectors allow the tweeters to 'turn back on' when power is reduced to a safe level.

•The RXE 065 will handle 0.65 continuous amps.
• Perfect for customers who keep 'blowing' tweeters.

PART# TM-100
 
   
 
 
TM-100 allows one amplifier to power both a subwoofer and a pair of stereo fill or main speakers. The Tri-Mode crossover passes the low frequencies to the subwoofer and the mid range and high frequencies to a stereo pair of speakers. Tri-mode crossover get the most out of an amplifier and provide a cost effective system for your customers.

You must use an amplifier capable of mono/bridged and stereo at the same time. Will work with any wiring configuration. Color coded for easy installation 12 dB per octave 100 Hz and down crossover to woofer. 6 dB per octave 100 Hz and up crossover to stereo speakers.

Electrolytics: Often a crossover with the needed crossover point or slope cannot be found. If you buy a mid range/tweeter set with a factory provided crossover and it doesn't sound right to your customer, you need to build one.
Non-polar 100 volt Electrolytics that will handle up to 250 watts of power and have a tolerance of less than 10% to insure that you hit the calculated crossover point.

• The M series will handle 300 watts of power, has a less than 3% tolerance and the esistance varies from 0.16 ohms for the 2.1 mHy model to 0.63 for the large 15 mHy model.
• All M coils have a plastic-mounting base to make installation a snap.The small S series will handle 300 watts, has a tolerance of less than 3% and the resistance varies from 0.03 ohms for the .05 mHy model to 0.19 ohms for the 1.8 mHy model.
• The lower cost L series coil will handle 300 watts, has a tolerance of less than 5% and the resistance varies from .3 ohms for the 2.1 mHy model and 1.0 ohms for the 10.6 mHy model.
• We use these same coils in our own crossovers, so you know they are good!
