Newbie Zen Question

VictorG · 13th September 2003, 09:12 PM

I guess I am just not getting it,

I've been building many DIY speakers and am now looking toward amps....

Of peticular interest is the Son of Zen, but I just don't get it. Now I'm no EE, but if you want "volume" in music, arn't you looking at needing a whole lot more than 10W. Is this amp just intended for low power aps?

If I am totally misunderstanding the concept, please enlighten, how can you tell how loud an Amp will sound on a given set of speakers?

Thanks,
Brian

How loud your amp will get mainly depends on your speaker´s efficiency. With a value of 90dB+ you could already be happy with 10W.
Regarding the Zen designs you also ideally have speakers with an impedance not too low (>=8Ohms). Although you could modify.
Do you know these values of your speakers?
Which speakers did you build?

Cheers
Jens

My system is a set of ESL hyrbids,

The woofers are the peerless 8 inch CSX variety
SPL: 89.5 dB 2.83V/1m

As for the panels I really have no idea. I am inclined to think only aroun 87 or 88.

I currenlty power these guys across a passive crossover with a hafler dh-500, this puts out 220+ watts/side.

The impedance is about 7.2ohm.

See i was just wondering how I could go from 220 watt per side back down to 10W per side, and still get a resonable amount of voulume. This is why I am questioning my knowledge of power/volume relationship.

Thanks for your help.

10 watts is a tough one for ESLs. Try something with more
power.
