hi,
I try to know the kind of sound I can get with those bright JordanJXR6HD speakers: I want to use them as main speakers outside of my sailing boat.
I desing the box in a WC exaust hose ( have to resist storm force wheather= see attached). It is a regular bass reflex 2.8l box / 3.6cm diam and 17.7cm long vent.
It seems to go a low as 85-90hz as shown by WinISD curve, but I found first the sound a bit "shrap" and in fact it appears on the typical response curve that it needs a slight attenuation (4-5 db) after about 300 hz. So I add:
an attenuation circuit
a 6db/oct- 10000 hz lowpass filter
an impedance correction circuit
All that could seem to be a lot for such small speaker but the fact is that I enjoy the result.Very precise , bright and not aggressive.
But I need your advises or experience about such filter for this fullrange
See fdoc attached an excuse my bad english
