Hey Everybody,

As you know I've decided to go a three way front stage after listening to XHELL's car and talking with Northfield Drew and just reading several other posts here on the forums...

Question now is, to run say the Focal 165W3's or the Dynaudio System 340s how much power will I need to supply to them and what is everybody running these from who has them??

I'm going with the Audison LRx series amps, due to build quality etc, and was thinking of the LRx2.250, but after consideration would it be better to go the LRx2.500 to give the speakers that little extra headroom, or would it not be noticeable?

Is it the general rule is to buy as much power as you can afford?

Thanks for your help..!!..

Are you intendind on running a fully active or passive 3 way setup ?

Hey Marc,

I'm just looking at running the 3-way front stage passive with the factory supplied cross overs...

I don't know about the Focals, but I know the Dyns love power - the more clean power you can feed them the better off you are. If your keen to stickk with the LRx series, get the most power you can afford - you wont regret it.

I can't help but think a 2.250 has to be heaps for a front stage.

I use a VRX 2.150 and play it loud and never clipped it.....general speaker efficiency will be quite similar Dyns and Morels.

Hey Peeps,

Thanks for replies.. I guess what I'm asking is would a LRx2.250 that is putting out 2 x 120watts be 'adequate' enough to run either of the two 3-way systems above decently?? or will giving them only this much power make them suffer and sound 'soft and underrated' etc??

for some high quality 3-ways as you propose, would be worth having the added power IMO. i guess it's difficult to place a dollar value on any 'benefit' you may see.

but, for the $160 extra (from the webstore ), i think it's a worthwhile investment.

good luck

IMO that would be a healthy power rating to give them. How much are the splits rated at? Most components are rated at about 40-80WRMS each so that sort of power will keep them performing to their best.

i am giving my 340 about 50wrms eac side and they sound great to me. they definately need more power and i plan on giving them a whole lot more:D.
if you can afford the extra cost, then go for more power. i would say that at least 100wrms each side would be the minimum.

If you are set on Audison the 2.250 should be heaps. There is only so much 'headroom' or power a set of splits can handle, the more power you get the more money you are wasting, where that money can be used on other things (if that makes sense).

bear in mind that the dynaudio system340 is rated at 200WRMS per side.

i would go the rated power...and then some

the dyn 3" midbass even has a 3" VC, so it can handle plenty of power...the guys at audioart have done dyn 3way installs with a tube driver blue 2150 bridged on each side (crossovers were upgraded to custom passives though as these are apparently the first thing to go)

i always try and at least match the cost of the amp to the cost of the splits, so if you're spending 1200 on splits, budget the same again for the amp

definately get as much clean power as you can afford as it will always sound better with more power on tap

I'm using an MRV-1507 V12 to power my focal 3 ways, sounds good, but I'm sure would sound better off a cleaner amp

IMO.....yes!

more power to front stage = better sound? pffft

c'mon guys, you are talking about speakers that are less than a meter from your ears and sharing the same air sealed and highly reflective cabin space as you - and your advocating feeding them MORE power than most auditorium PA systems use?

seriously, spend the $$$ on good speakers and quality pod work

T Bro is perfectly correct.

You cannot underpower speakers period. All any extra power does is make them go louder before amp clipping kicks in, provided you dont reach the physical limits of speakers. This is often a good thing (more power) as many ppl want high output, but wont pay for it, so push amps beyond limits, trying to get volume they desire.

I run around 150 W to each side with my sys 360s, but less power would just mean I couldnt go as loud as I can now. As my amp is conservativaly rated its probably more power, and the Dyns sure dont have a problem with it, but the power is just about volume, not SQ, as when my systems judged for SQ its not using anywhere near the amount of power I have on tap.

Anyway if more power isnt going to add huge amounts to costs Id go for it, as crankability is nice, but dont kid yourself it will effect the SQ, as it wont.
peace

InCar Mag #54 (May/June 2002) - VW Passat with a pair of 6.5" Midbass drivers per door, fed 1400wrms per side (yep!), with another set in the kicks, getting 580wrms each. Add horns, and.....

Probably sounds alright too, eh??

Just showing an extreme example of what *can* be done. For the rest of us mere mortals, a quality front stage amp, IMHO, should have 100-150% of the rated power of the speakers it's driving on tap.

Nice setup on that Passat tho: the Monster Cabling and other power gear in there would probably top the budget for my entire system!
