DIPOLE
SPEAKERS
I work a lot with the design of speakers systems.
Here I will show some of my dipole speakers.
Here's a big set-up of some
stunningly good dipoles. The sound of the speakers is controlled by DSPs. Each speaker is measured with a measuring microphone and calibrated. The DSPs also contain the 48dB Linkwitz-Riley crossover. With this filter and correct delay, all speakers will play fully in phase. The result is absolutely fantastic. |
The round speaker is a
Visaton B200. To this there is a Visaton sub with 12 "and 10" to the right of the B200. The crossover frequency is 300 Hz with a 48 dB Linkwitz-Riley crossover. The B200 provides a great vocal sound reproduction even at high volume. The left speaker is a three way system. Treble and midrange is a Seas H1699. Bass is two Visaton 10 "speakers. A three-way DSP crossover and three amplifiers are mounted on the back of the plexiglass plate. |
Here is a dipole line array. This is made for larger premises. The range of sound from this is great. A DSP filter with 300 Hz crossover frequency is used here. This layout is made for a big barn party. |
This is SEAS / Visaton
dipole. DSP and amplifiers are mounted at the bottom. |
An absolutely amazing
speaker, Visaton B200. With DSP calibrated with a measuring microphone, this sounds great !!! DSP is ADAU1446. |
Rack with amplifiers and DSPs for the line array and B200 system.
I calibrate the DSPs.
Testing the big speaker system before the barn party.
The result is very good.
Here we see the linearray from the back.
Super Hi
power bass / mid-range horn.
This is one of my most
successful horns. It consists of a 10 "speaker in a 2 liter pressure chamber. The frequency response is 150 Hz - 700 Hz. In this area, the efficiency is 42%! ! ! ! Have you heard of something better? At 200 watts, the sound pressure is enormous. |

VITAVOX S3
I clean in the basement, where I found these Vitavox S3 horns.
These sound extremely good and they also play extremely loudly.
