też myślałem o 60-80hz, od takiego głośnika nie oczekuję cudów jak już pisałem. Czytałem, że parę osób zrobiła go w tl i raczej sobie chwalą. Głośniki mają grać przy laptopie, na biurku nie daleko ściany. Jestem za monitorem, znalazłem też filtry do tego głośnika,
Głośnik będzie zasilany TDA1554Q.
Well, I got some new electrical componants to play around with and figured I'd revisit this project. After a few hours of testing different BSC's and notch filters here is the combination I liked the best;'
BSC
R = 4 ohms
L = 0.8 mH
Notch
R = 16 ohms
L = 0.11 mH
C = 4.7 mF
I say this is the best not because it had the absolute flattest FR but because it sounded the best to me. The main thing I was looking for was;
1) Decent free air (4pi) bass response without making the treble sound stuffed (something that hapens with too much BSC).
2) Taking the 7kHz shrillness / breakup out.
3) Maintaining clear treble (can be tough with these drivers).
Testing the bass is easy - it's there or it isn't. I found a set of songs that highlighted the shrillness I noticed. This included the moaning part of Rusted Root's "Drum Trip", most guitar by Satriani and "Mandelgroove" from Blue Man Group's "Audio". I've started trusting my ears more then my gear to know what will make me happy.
ale z tego co czytam jest to do modelu 656 :/
