ELTIM DIY Speakerkits

In today's DIY world it seems to us that the only "correct" speaker is a bassreflex one with a 17-18cm midwoofer, a 21-28mm tweeter and crossed by a 12dB parallel crossover. Where are those days where so many other setups showed fantastic results.....??
We also notice another thing: frequency curve has to be absolutely flat! Why? If you put it in different rooms this curve is dramatically altered by the room. We go for flat impedance and phase curves instead resulting in better 3D and rock solid bass f.e.
In last 15 years we, as MOREL Europe till 2014, developed quite a number of speaker kits based on MOREL drive units. Over the years we made lots of DIY designs and today we list the best sold ones only. We developed a calculation program where we can enter all speaker acoustic performance parameters combined with the behaviour of a serial 6/6 crossover, resulting in a very natural sound, free of side lobes as all parallel filters show. We see the changes in impedance, phase and frequency in graphs while changing parts values. This results in absolute flat phase and impedance curves, even around the woofer Fs. This latter makes you smile while listening to the bass behaviour which is massive, solid and fast. With a 16cm woofer there is no sub required!
Curious about the results of our different approach and way of designing? Read a 6moons report about our SOLO project, also with (just a single) 16cm MOREl driver.
