2 way louspeakers

[bracika]

Dear Collegues,
There's something I want to share with you.
I made it in past five or six years. I hope you'll like it.
My plan is to make something new, maybe open baffle design, I don't know yet.

I hope I get more time in second half or the year and make my dreams come true - OB 3-way loudspeakers. It's challenge.

Zdravo Drazen,

Saljem ti moj post i nadevam se mozes mi pomoc


I have wharfedale diamond 10.4 (2.5 way passive crossover).
I would like to make an active crossover but im very confused of meaning of two and a half crossover. Could i build 3 way active crossover and use it with these speakers?

Original crossover diamond 10.4 - bass 40-140Hz, midd-bass 140-3800Hz, highs above 3800Hz.

cut off frequency for bass 6dB
midd-bass 12dB
highs-12dB

Another problem is gain of power amplifiers. For midd-bass and highs i would like to use SE power follower 99. This design doesnt have gain so im using tube preamp with gain 30.
For low frequency 20-140Hz i will use Marantz PM 44 SE. I dont know the gain of this amp. If there is possibility to measure gain? Or to change the gain by changeing the components on circuit board of that amplifier. I dont want to use volume control to change gain.

I think they do sound as good as they look. I also like mini monitors, but standmount loudspeakers ...is standmount, especially 3 way.

Mostly used Vifa. Some of them (midbass) are modyfied.

"Amedeus" - the red one is based on Vifa XT drivers.
