    If there was a perceptible difference in the bass response between a Rane and Ashly analog crossover one of them is broken. The circuitry just isn't that different. Did you test the suspect crossover...

    Based on my testing of Chinese knock offs of EV DH1 diaphragms you have about a one in four chance of getting parts that match the original - or each other. Now that was ten years ago so perhaps...

    That is the driver used in the current mid sized VTX20 line array box . If you've been to a show using those boxes you've heard lots of those drivers. In those boxes the drivers ( it uses three...

    Curious as to why you chose second order crossover filters when you had fourth order available and why you chose the 1/3 oct for the eq rather than the parametric.

    36" is the correct dimension. I know because a pair of the cabinets stacked put the horn on top at eye level with me. We used the 2220s because they matched the 2220s we used in the 4560s at the time...

    It helps to keep in mind what different speaker system designs were intended for when they were new. The 4311s were designed to sit on a shelf along the meter bridge of a studio mixing console for...

    They sounded great with dual 2220s and others with K140s. I painted them grey and trucked them around the countryside using them for concerts. Probably not much help in answering your questions but...

    Nothing wrong with well designed plastic horns. Itís aluminum that makes a poor material for horns. The 2350 & 55s had to be coated with plaster to reduce the resonance but never really eliminated...

    One trick people experimented with back in the day ( before we gave up on 4560s altogether ) was to mount a horn in the 4560 horn with the HF driver acting as a sort of low budget phase plug for the...

    I suspect he means the vertical distance between the woofer and the horn. In front loaded speaker systems this distance would likely be less than one wavelength at 1khz. When listening at a distance...

    Hate to say it after the fact but it's actually easier to damage a speaker rated at 100 watts with a 20 watt amp than with a 200 watt amp. Music by its very nature requires the most power to produce...

    The 2350 radial horn was often used with the 4560. Makes life pretty hard on the 2440 / 41 drivers often used with them but that's how it goes when using a speaker cabinet designed for 1950s movie...
