#1 WHY THIS DARTH VADER STYLED BOWL?
Shape of the enclosure has a vital role in the performance of the loudspeaker. Moving of speakers causes sound waves with very complex mixture in terms of frequency, amplitude, phase etc. If the shape is rectangular with parallel walls at certain frequencies two bad things may happen: the wall will start to vibrate due to interference and they will act as additional speakers, but without control. So the general sound will be unpredictable mix of the sound caused of the speakers and box’ walls. Second: standing waves will occur inside the cabinet which will raise enormously certain frequencies and will defeat other. So, why most of the loudspeakers have a shape like kitchen cabinets? Because it’s easy and cheap to do and many loudspeakers manufacturers do not manufacture the enclosures indeed but over source them to cabinets manufacturers.We went to the difficult way: we chose a shape which prevents both a.m. phenomenon. This shape is oval.
#2 WHY ALUMINIUM BOWL?.
Because of the complex design of the enclosure, the best manufacturing method is casting. The enclosure has primary function: avoid problems with interference and resonance and secondary: to be easy for processing. Most common materials for casting are many types of plastics. They do not have so good acoustical specifications and they are made of petroleum. We decided to use aluminium alloy like the aircraft one, because it has very good acoustical possibilities, it’s easy to be finished and it is not petroleum based.
# 3 WHAT IS “LIQUID STONE BAFFLE” AND WHY?
It is our formulated compound we cast in factory. It consists of marble stone, polyester resin and additives. The result is material which is very near to natural marble -
#4 WHY SUCH SHAPE FOR THE BAFFLE?
To avoid screen effect. When the baffle is flat and glossy another phenomenon may occur: it can act as reflector (in the similar manner as torch reflector for the light). Some frequencies will be enhanced but again out of control. We design very carefully our baffle and test it continuously in the anechoic chamber.
#5 WHAT ARE THE HORNS AT THE BASS PORT AND TWEETER FOR?
The tweeter’s horn is designed for uniform dispersion of the high frequencies, while the bass port is to reduce the turbulence and thus reducing the parasite noise.
#6 WHY SHARP FEET?
To avoid any possibility to transmit vibrations to the surface the loudspeaker is put on.
#7 WHY HANDLE?
You will love your loudspeaker and you will want to take it with you. Take it in the safest way.
