W00t! Dynaudio Audience 50's

Jimbo Mahoney · 27 Jul 2006 at 15:12

Just bought a pair of Dynaudio Audience 50's - my (realisitic) dream speakers!

£215 2nd hand incl delivery

Obviously, I'm looking for you guys to say - "Bargain" and "Great choice!" etc, as well as reassuring me that my modest NAD C320 (40W per channel) will drive them in a 5m x 4m room at low - moderate listening levels :rolleyes:

They'll arrive in the next few days, although I won't be able to use them for a couple of weeks until I get my HiFi back from storage (just moved to Belfast, so most of my worldy posessions being stored).

The amp will be the next thing to get upgraded, but not for a good while.

They will replace my Celestion F20 floorstanders, which will be relegated to fronts in a home-cinema project.

I'll sell you my C320

hehe, I was mostly joking, as the C320 is fairly entry-level and I suspected you would be after something with more grunt.

Re: impedance - my amp will do 40W continuous into 8 ohms, with 90W peak into 8 ohms, but it only gives the peak into 4 ohms - 125W. Is there any way of estimating continuous power into 4 ohms from this? It's also specced at 160W peak into 2 ohms.

I know the Dynaudios are hard speakers to drive - 4 ohms and only 86dB - and I want to be certain the amp can handle it without clipping. On the plus side - I've run the amp with a pair of Audience 60's without problem, and the amp has both "ISC" (impedence sensing circuitry) and a "soft-clipping" switch, which I could turn on if I'm worried.

CD Player is also NAD - C541i

I'm actually rather tempted with something like a Roksan Kandy amplifier... (then maybe the Kandy CD Player to follow...)

EDIT - and 'decent', not 'descent' (sorry, grammar Nazi in me, but seriously, just trying to help)

you sure the C320 has ISC? I have a C320BEE and that certainly does NOT have ISC nor PowerDrive.

The C320BEE certainly DOES have PowerDrive (which is ISC + tweakage), and the C320 just has ISC.

With 125W peak into 4ohm, you should get 88.4W continuous/RMS. This is 125/square root of 2 (1.41). Realistically, there are other factors (efficency drops, power supply sagging etc). Say 70W continuous

Thanks.

How come it gives 40W continuous into 8 ohms, but 90W peak into 8 ohms?

I make that 64 Watts continuous into 8 ohms, based on the 90W peak?

:confused:

Wierd, there is no powerdrive logo on the front and it says nothing about it in the manual.

Maybe you got a duff one?
