Happy New Year!
During the Christmas-holiday I finished my Quattro. I attach you some
Sounds is very good. I have a special tube amp which push the low
frequency more than the usual amps (Almarro A318B), so the low frequency
was a bit too much. We made a test with a measuring microphone and we
found my room is the guilty, because it increase the low frequency.
Around 40 – 50 Hz I have some “mountains”, so we made a room-correction
based on our measuring, and the final result became marvelous.
Beside the frequencies the Quattro also very good in sensitivity. I
found the music very detailed and responsive: it is really a good design
with good drivers. We compared it with a Dali Helicon and I found
Quattro has the nicer sound. Of course – it is a huge (for me) liter
volume box… But as far as I found I cannot have the good sensitivity
(90dB +) with smaller boxes.
