BLH/TL Build for Dayton RS100-4

[Scottmoose]

I haven't got Hornresp loaded at present & I can't remember off the top of my head how it uses definitions; most common is terms of radiation angle or radiation space. For e.g.,
1/2 space = speaker sitting on the ground with no walls nearby
1/4 space = speaker sitting on the floor in close proximity to a wall (usually but not invariably a front wall)
1/8 space = speaker sitting on the floor in close proximity to a corner (i.e two angled walls)

All of this is a little late but you can find the plans at the link. The notch filter I have written down but didn't include with the plans. I ended up using an 8.2 uF cap, a 7 Ohm resistor and a .22mH inductor. This gives around 10 db of attenuation. You could reduce that by using a 3 Ohm resistor and that should take it to about 6 db of attenuation I believe.

I am hosting it on my business webpage so forgive the odd link.

this Notch filter is Parallel or Serial one?
