Re: Melded piezo array for a direct drive (non-horn)

I did something wrong (i was running the piezos on separate channels and the power wasn't equal), and i also listened the speakers more. Here is the plot, red is without horn, green is with horn. They still sound quite identical, but the 5 kHz dip and the less output over 14 kHz is clearly audible f...

Re: Melded piezo array for a direct drive (non-horn)

I had the opportunity to experiment a little with some piezos using a really flat response electret mic. Of course i know i'm not the first, but here are my results: - Tested 2 different piezos with (on paper) different capabilities, identical looking to the Monacor products, but not the same factor...

Re: Melded piezo array for a direct drive (non-horn)

You guys convinced me and i'm going to build a pair of OmniTop 12. I need to solve the "sub" problem tough. A pair of Omni will take a lot room from my car, and i'm afraid a Tuba 24 will not be enough for the low end.

Re: Melded piezo array for a direct drive (non-horn)

Sound is sound. What gets delivered is what's important, not how it's delivered. If a horn sounds better - it sounds better. Doesn't matter what type of music you are putting to it. A mid-range horn adds some color to the sound. Or at least all mid-range PA horns i listened so far in the last 20 ye...

Hello, i don't have proper measurement tools here, so i'd like to order a prebuilt tweeter array from speakerhardware.com.
