The Kii Audio Kii Three, is a briliant construction and innovation setting new standards for a small speaker this size. Brain child of not least Bruno Putzeys, the inventor of the UcD class D amplifier topology and co-owner of Hypex, it builds on the heritage of small active studio monitors but with some distinct refinements. Another speaker of the time is the rivaling Dutch & Dutch c8 which shows much the same performance with regards to constant directivity but implemented in a different way. The speaker is of course fully active, and the filtering is done i the digital domain … Continue reading What Drivers Do They Use? – Kii Audio / Kii Three

Just bought myself a new subwoofer set. Earthquake DBXI-15D and SLAPS 15, a combination used in Earthquake’s Supernova 15 sup which cost around 3000 euro. The active driver is a 15 inch long throw unit with a linear Xmax of 37 mm one way! Will try the combination in a 72 liter box, which is the recommended volume from Earthquake, and I think similar to the Supernova. The T/S parameters given by the factory does not make much sense and can’t be real. So it is impossible to simulate up front. I think this is not really professional of Earthquake. … Continue reading Earthquake DBXI-15D + SLAPS 15

Read on: Having burned one of my midtone drivers, a renowned ScanSpeak 13M 8636, which has served me well for many years.

Actually I find it a rather steep price no matter what, but it is actually quite good. But instead I looked at alternatives, well knowing that just changing a … Continue reading Replacing Scan Speak 13M Kevlar with Dayton RS125
Many years ago I purchased a pair of Cerwin Vega D5e speakers for the money I got in present for my confirmation party (15 years old). I had these speakers through my teens up until I was on technical university where I build a new pair of speakers. They served through many parties, running uff my NAD 2020. Really efficient speakers capable for playing really loud in modest rooms with the only 20 watt of power. Amazing 🙂 I sold the speakers long ago … to get only a modest amount of cash … why 🙁 ….. Now some 30 … Continue reading Refoaming a Cerwin Vega 12 inch woofer

On paper the 6.5 inch D-165 looks really promesing.Link to shop: Reckhorn Amazing build quality for 30 € only?!Fast delivery and nicely packed … good job Reckhorn 😊 The passives are not as impressive and quite flimsy. Seem the suspension is somewhat more soft than the D-165 .. giving a lowe Fs. Comes with 3 small discs to add weight to the 20g alu cone. Plan is to build a small active sub in a box of 11 – 15 … Continue reading Reckhorn D-165
Retro look, good sound, and bringing a great speaker to life again Decided that we need some music in our living room. We have a separate listening room / home theater, so what we need is just to be able to play a little music from Spotify etc . I had a small dream of doing some retro, and restoring an old classic or something, which looked cool and play ok. A month ago I saw an add, to pick up a pair of Avance Concrete 180 speakers, for 25 Euro. They looked ok, but the foam surrounds on the … Continue reading Restoring Avance Concrete 180
