please need advice on mid/woofer

6ri.l · 25th February 2007, 01:50 PM

hi, what do you think about this driver in a 20 ltr bass reflex enclosure.
it's for listening electronic music, jazz, and some rock.
so for electro music, i need deep, clear, precise and detailled bass and mid .
and wich kind of tweeter can i put with this driver?
thanks a lot.

At what freq do you plan to cross?

6ri.l · 25th February 2007, 02:52 PM

i think near 2000/2500 Hz.
do you think it's a good choice?

I'd cross it over sharpish, perhaps around 24 dB/octave, because with shallower slopes the peak at 4 kHz will intrude on the tweeter.

i'm sorry but i don't understand what do you mean, my english is not good enough, do you mean i need to cross it more higher?

He means steeply,
babelfish gives me 'en pente rapide'

an excellent mid/bass driver, but for electronic music I don't think it goes low enough, for satisfactory lows I think you need a response down to the low 30s. This driver with a sub of some sort would be an excellent arrangement (or a 2.5 way).

As for tweeters, Peerless make good ones, as do SEAS, I'd probably use one with a low FS so you can cross over around 2Khz
SEAS 27TBFC/G is a very good choice

C'est ce que j'ai voulu dire, mais etant donne que la plupart des gens ne parlent pas francais je l'ai dit en anglais.

En tout cas, la frequence de 2000 Hertz est bien choisie, mais vous voulez une pente de 24 dB/octave sinon vous allez avoir des pepins aux alentours de 4 kHz parce que la reponse du woofer sera de trop, meme apres le crossover.

Ceci dit, je vais me taper un verre de vin de Californie. Sante!

Thanks for all these good informations.

I think i'll build these one, and maybe if i want more bass, build a sub.((-i' have just finished two fullrange with sph-60x from monacor, good definition of the sound but under 60hz the bass are really really bad-))

Sreten, thanks for the url, many good things about the filter.
now i have to work...
DSP_Geek, merci pour l'explication en français... c'est plus clair, (i have to work my english !!)

Just one other question, about the phazing, how to calculate, where do i put the drivers?
And for the cabinet design, i've read on the web that it's better to have a deep cabinet and a not too large front baffle, it is right?
