Go for the higher amp power and a limiter if you must.You should ideally be running your system with an amplifier which can deliver more than the speakers can take thus ensuring you have a clean signal getting to the speakers.
Class D speakers I have no knowledge of but I can tell you that I run a pair of Turbosound mid-hi boxes rated at 150watts rms at 16 ohms a side.This then translates to 300watts rms at 8 ohms.I drive these speakers off a Crown amplifier delivering 650watts rms into 8 ohms without limiters and have done for years without blowing up any drivers.It all depends how careful you are in setting up your system,what components you are using,and how efficient your system is not necessarily about rms as you rightly say!!

ive recently bought a pair of peavey 12s ul series,do they have crossovers in them for when i add a bass bin ?and if my peavey 1200 watt amp has 4 ohms per chanel output,can i not only connect the 2 speakers of 4ohms but even add a 8ohms speaker as a monitor ?

my gear

1 peavey 1200 watt mixer/amp- 600 each side at 4 ohms
2 4 ohms each output

what am i allowed to add ?

If your amplifier is only rated at 4 ohms per channel, and you are already running speakers of 4 ohms per channel then thats about your lot. Driving into loads below 4 ohms may seem to work okay initially but can stress the amplifier components and lead to overheating and even failure. If you want to connect additional speakers of either 4 or 8 ohms to the same amplifier as your existing 4 ohm speakers, then you need to invest in a decent quality amplifier which is capable of driving loads down to 2 ohms per channel.

If you want to add additional speakers or even a monitor then why not invest in a powered (active) speaker?

cheers for that,....

why is it that the guide says to use an amp thats 50 watts lower than the power of the speaker. When i joined the forum i found a link on here to an external site with many DJ guides which i printed and read. The one on speakers clearly stated that the best sound will be produced when an anp is higher powered than the speaker, as running an amp at a high volume level will loose quality. ie 8 ohm 300 watt speaker should have a 400watt amp powering it.

does that mean that a 300watt 8ohm speaker is able to run at 600watt @ 4ohms?

Hi all,

I've been offered a pair of these

http://www.jblpro.com/catalog/general/Prod...Id=93&MId=6

barely used at a great price, tried em out and they sound good. I know they have been discontinued but really like these. Can anybody recommend a sub to go with them? Will one of these below be sufficient for the pair of speakers? Was actually gonna buy one anyway to go with my passive EV's but would like to have a spare set of speakers just in case, hence thinking of purchasing the above.

Or will I need a bigger sub than that to go with the powered JBL's? I normally only do small venues but have started to get some weddings in pretty big rooms now so need a bit more power. Im a bit clueless when it comes to sound equipment

Everyone’s tastes are different. There is no best speaker, only the one that is best for you. When you shop for speakers, listen to several models with familiar music. Take your favorite discs with you when you shop and identify speakers that sound good to you. Your experience in listening to live music is a good gauge to evaluate speakers. The speaker should sound natural to your ears, have balanced tone quality and should be easy to listen to for long periods. Don't feel rushed, listen to a speaker several times before making a final decision.
