Hi amigos,
Let me introduce my new DIY floor speakers (2.5 way) based on the "ESSentielle ADS" diagram of "la maison du haut parleur" (MHP)
The cabinetmaking is made of French Ash wood with a vertical grain. (25mm)
These speakers are based on the famous ESS Heil AMT 3 Tweeter (latest generation) and two Satori MW16PNW-8 Woofers in Egyptian Papyrus whose measurements are here:
http://www.loudspeakerdatabase.com/SB/MW16P#8Ω
The Crossover was the subject of a patent after two years of R&D with a gain adjustment, it is manufactured by the "Maison du Haut Parleur" in Toulouse, still in France. It has been specially developed to get the best out of the ESS Heil AMT3 Tweeter.
This Crossover is mounted with discrete SMD type components. The Woofer part is filtered at 6DB / octave with two Jantzen Selfs (Grade 1B copper wire @ 3% / 0.10 Ω) with a very low DCR.
Here are the cutoff frequencies:
385HZ/1700HZ.
Bass Woofer can go down to 32HZ @ +-3DB
I wouldn't be very objective if I gave my opinion, would I?))) But I'm in love with Heil AMT3 Tweeters and I must admit that the first time I listened to these speakers, I took a real slap!
The Satori Woofers seem to marry very well with the ESS Tweeter, the listening is musical, detailed and of a beautiful straightness.
For ESS fans : you can listen to the DIY kit in Paris / Toulouse and in Lyon if you are ever passing through) They are available in a version with a different cabinetry and less elegant than my DIY version but listening and electronics remain the same.
And here are the pictures
SPECIAL Thanks to Anthony if you read me )) #fan de l'atelier des Apôtres"
