A 3-way active crossover design study

[Vineethkumar01]

I went finally with a series crossover as parallel type was getting difficult to control the 2khz hump even with a contour filter. I have to finally measure them after implementing them - one channel. I have listened whole day today and did not notice any issue- though my listening skills are not very greatly developed. Having said that, i am happy with what I listened.

Glad to know. Thank you for sharing

I have been through many 2-way and 3-way system configurations by now.
These are the two systems which I like the most (as of now):
(All curves/spinoramas shown below are based on actual polar frequency response measurements of each driver and the overall speaker). I am just showing a few measurements out of literally thousands of measurements I have captured for the speakers, both for crossover design and for overall system response validation

1) 2 way system with ST260 horn on Peerless DFM 2544R compression driver + Dual Satori WO24P-8 woofers

Crossover

System response curves/Spinorama

Preference score

2) 3 way system with dual Satori WO24P-8 woofers, wavecor WF120BD03 mid and SB26CDC004 tweeter on elliptical waveguide

Crossover

System response curves

Preference score

Impulse and step response curves (in room, without windowing/smoothing)

Gated far-field responses on (tweeter) axis for left and right speakers

I think my explorations with speakers relevant to this thread are coming to an end with the above designs..
What is remaining now, in this regard, is to do a little bit of room treatment to reduce the flutter echo and, in general, improve the room acoustics a bit

Thanks
