Ok.. I am starting to look into Dyn's as another option for my front stage.
Having a loot at the Dyn website it says that the System 242 GT has a continuous power handling of 100WRMS.
I thought "Sweet" because my Focal FP2.150 will push out 150WRMS.
I rang the local dealer of Dynaudio to get some prices and when he found out what my amp was, he said "Oh" that it would not have enough power and usually they push up to 1k per side into them and pretty much said that you would not want less and 400-500WRMS..

Now.. I am no noob to car audio.. I know that head room is good - I used to push 150WRMS into my Focal Polyglass splits and they sang beautifully. But... To say that you need this sort of power for a speaker that is rated at 100WRMS, does not sit right.. Yes, I would like to push about 200-250, alas, I cannot with these amps..

What are your thoughts?

Or would I be better off running KRX2's which are 2ohm and get 200WRMS out of my amp? Personally I am not sure if the increased THD for 2ohm is worth the extra 50WRMS..

150wrms a side will be fine.
sure alot of people seem to think that dynaudios only really come 'alive' once u start pushing ~300wrms into each side, but i say bollocks.

Had 200Wrms on the 240GTs and could cause the passive xover tweeter protection to kick in on hard rock/metal styles of music... So who knows.

150wrms will be fine..

i've had 300wrms a side into my 242's full passive, and 2x300wrms (@4ohm) + 2x ~200wrms (@6ohm) into them active..

run the dyn's off the current amp.. if you feel it needs more (and you can afford it), add another amp later..

2nd on the 150 per side - any more and they can bottom out@63Hz crossover.

[blue_6006]

Thanks people.. I thought this would be the case.. It makes me question what sort of amp they are pushing "1000WRMS" with....

[jas]

1000watts rms per channel

which single amp would do that?

only things that could do that would be bridged 4 channel amps and even then it would be a stretch.

short list that might come close:

RF Power T15004

The Audiosystems Mosconi AS 200.4

Can I ask who the dealer was?

400rms is warranty voiding power and if not setup correctly, could damage the speakers.

As above, The amp you have will be fine. Dyn's are pretty power hungry but they will still sound great with your amp.

I think he meant total power in an active setup.. Still in an active setup, 150WRMS would be even better because less is wasted in the passive XO.. So either way the logic is flawed.

Hey mate, I do not want to flame anyone directly on the forums.. But lets just say there are few Dyn dealers in Perth.

The dealer was me

There are a number of our customers that use large power amps (multiple 2ch amps) to run Dynaudio speakers.

One in particular uses two Treo 2ch amps that are rated at producing 1000wrms bridged into 4ohm, one per side. There is an Alpine PDX 1.1000 running the Oz Audio woofer and the system sounds really good

The only speaker failure that I can remember is an Esotar midbass that was running active from the bridged channels from an Arc Audio KAR series 4ch which is in Pete's car.

The midbass has been replaced and has been running fine ever since, it was only getting about 250-300wrms IIRC

I feel that Dyns come alive with >300wrms running them per side, as for voiding warranty there hasn't been a Dyn failure other than the one that I mentioned that I am aware of.

150wrms would be the bare minimum I would suggest running them with.

AHA! LOL..

Yeah, if you have the luxury of power - why not use it? As I said, I was pushing 150WRMS from a Sony XES M3 into my Polyglass mid's and 60WRMS from a XES M1 into my tweeters and it was amazing - so yeah power is always good.

If everyone turned around and said do not bother trying to power them with that amp, then I would not buy the speakers or get a better amp if I wanted them that badly so was just checking for user experience.

Anyways, I will try and pop down to have a listen to them on the weekend.

That i could agree with... I had 300wrms going into my dyn passive and they sounded good..
ran active with 4x 300wrms @4ohm (4ch bridged per side) and they really sung...

Its all about gain control i'd say....

[HEKYEH]

Exactly...gain control is very important.

Just because an amp is rated at 300wrms x 2 doesn't mean the speakers will actually get that much. They may only be getting 150wrms...

Hmm, possibly the protection was kicking in due to a slightly clipped signal?

Sure have, I'll dig them up and get someone to show me how to post them up on the forum.
