You don't need to do anything special other than store them where it's not damp, lest the plates rust. -
The crossover doesn't change the width of the radiating plane, and that's primarily what determines horizontal dispersion....Leave a comment:

When you have the mids on the horizontal their combined dispersion is narrow on the horizontal plane, wide on the vertical plane, the opposite of what...Leave a comment:

With the cost of holding large inventory being so high it's more and more common for retailers to take orders but the actual item is drop shipped direct...Leave a comment:

A horizontal MTM defeats the entire purpose of an MTM. Going back to the original topic, JBL was aware that the horizontal arrangement wasn't ideal. To...

With close enough spacing and sufficient crossover slope you can get a good result, but make no mistake that when speakers have been built this way it...Leave a comment:

Where bass horns are concerned pattern control doesn't exist even close to the horn cutoff frequency, because you're not going to see one wavelength mouth...Leave a comment:

Without seeing the actual post I can't say if he said that one couldn't play lower than the tuning of a horn. One shouldn't play lower than the tuning...Leave a comment:

That's because they don't go low. On average a home theater sub goes an octave lower than a PA sub. That said, drivers with only 4mm xmax aren't going...Leave a comment:

PA drivers trade off low frequency extension for high sensitivity. DSP may be used to fine tune speaker response but it won't change the driver specs...Leave a comment:

I haven't seen any comparisons of IM in horns versus direct radiators. Doppler tends to be a problem with longer excursions, which is exactly what modern...Leave a comment:

With regards to the cabinet walls, I've made cabs with round ports located mid baffle, and triangular ports of the same area and length placed at the...Leave a comment:

True, but if it made the box effectively larger the tuning would go down. The response curve that results from a lower Q, especially in a sealed box,...Leave a comment:

Only those of us who like high sensitivity and inaudible THD.

That's not what stuffing does. It changes Q and impedance. You model it in WinISD in the Box menu, using the Advanced tab. Change the Qa to see the result....Leave a comment:

HD with tweeters is similar to with woofers. It has little to do with Fs, other than the closer to Fs the tweeter is run the greater the excursion and...Leave a comment:

Coloration would be linear distortion, since the reproduced signal differs from the original in the relative amplitude of different frequencies. Harmonic...Leave a comment:

Where time align is concerned it's primarily an issue if the woofer and tweeter approach 180 degrees total phase shift within the crossover region. One...Leave a comment:
