High efficient closed 2(.5)-way system

Ralph · 30th December 2003, 04:54 PM

Hi all,

I'm currently looking for a new loudspeaker project. Untill now I've been playing with a 2 way BR monitor, with SS units. Because I'm changing to a tube amplifier I like to build someting a little more efficient. Have looked at various kits and designs but haven't found the right thing I guess. The new loudspeaker should be a monitor (2 or 2.5 way). I'm planning to use an active sub with it.

What I would like is:

1/ top quality units, now I'm using a 18W8546 and Revelator tweeter
2/ closed system, not bass reflex
3/ effeciency around 92dB for 2,83V/1m
4/ flat imp min 4 ohm
5/ f3 of around 80-100 hz is low enough

Like this one, very nice I think, but can't contact the owner ...

Can you come up with more ideas?

It all comes down to money. /hehe

High sensitivity designs... hmmmm
try this old thread.

PHL / ESg 3 way question - AR2

If money is no object, this 103db sensitivity tweeter sounds
excellent, $600 US. /hehe

Hi thylantyr,

I did and he came with the following suggestions:

1) 2x PHL 1120 + G2 in closed box. F3 will be around 250 hz. So in that case I need a basssystem, like a one with a Lamba TD15 you wrote about.

Question about this configuration. I read in another thread that the TD15 is not very efficient in a closed box. Is that true? In that case I need to drive it actively.

2) 2x PHL 1240 +G2 in closed box. F4 will be around 90 hz. In that case I need a powered (sub)woofer crossed over at around 90hz.

Millenium tweeter and two Accuton C95T-11 midbasses. Mind-blower if you can do/get a good XO! Relatively small sealed box.
