Default Driver/box recommendation

Hello all,

A friend couple ask me to build new speakers, and like Metronomes. Only condition is no taller than 1,25 m, then I'm limited to 4-5" drivers. Any recommendation?. Now they are listen music with Beyma 8AG/N and they're happy, but the box is too big.

I would prefer high efficiency speaker (Fostex ?), because amplifier will be Tripath2020 or Sure TPA3110.

They listen pop, indie rock, jazz, folk, never classical music. No subwoofer here, just full range.

Your suggestions will be very appreciated. Thank you,

Victor

The cornu fits many of the requirements and was originally designed for a FE108ESigma, but can work with FF125wk.
Ever think of building a Cornu Spiral horn? Now you can!

Dave,
You are right, but why ask for recommendations if you know you are building a Met?

I suppose he is looking for a driver recommendation.

OTOH I know what my drivers are (see below), but I am hoping for assistance with metronome cabinet sizing to suit the driver.

I have 4 of these drivers and a Metronome bipole looks like a good project.

Driver parameters are:

Fs 79 Hz
Re 7.3 ohm
Z 8 ohm
Qms 2.8
Qes 0.29
Qts 0.26
Vas 6.2 litre
Mms 2.9 g
SPL (1W/1m) 92 dB
Sd 55 cm2
Rms 0.55 kg/s
Cms 1.43


Thanks if anyone can help or advise me.
I am still stuck on this project and would still be grateful for any thoughts.

cheers

I have the same drivers and was sure I found the sizes in this thread somewhere.
I'm on the road right now but will check my records when I get home

He was asking for suggestions for drivers to put into a Met.

Dave, tnargs

You are right, I'm asking suggestions for drivers that suits well in a metronome. Around 100-150 $ per pair.

Thanks

Victor

Thinking of a compromise between getting bass and good efficiency, you might consider the Fostex FF125wk
