this might sound stupid, but which is louder a 30W amp 2x10quot; speakers or a 60W amp with a single 12quot; speaker?

What's the wattage are the speakers? Their wattage will determine which is louder but I can tell ya, going from 30W to 60W isn't all that much of a difference db wise.

Well, actually it isn't only the wattage but also the sensibility which matters.

it's actually the behringer GMX210 and GMX112 amps. the GMX112 isn't out yet here so i can't test them side by side. i want to get the louder amp.

Wrong.

Speakers quot;takequot; wattage they don't quot;makequot; wattage. The main factor in how loud a speaker will play is it's efficency/sensitivity. (not sensibility! whew...) That's how much sound it will make given a certain amount of power.

A 30 watt speaker and a 60 watt speaker driven by 30 watts of power will put out exactly the same amount of volume if their efficency rating is equal. The advantage of the 60 watt speaker is only that it will handle more power. But the extra 30 watts will only net you a few more dB.

All things being equal 60 watts will be louder but not by too much.

So you inital question can't be answered until you know the efficency of the speakers in question. But my guess would be the 60 watt amp would be a little bit louder.

Yes, I know they take wattage but for example, two 75 watt speakers in a 2x12 and even a 4x12 will be louder than one single 75 watt speaker, assuming they are all of the same type and efficiency and having the same amount of power fed to them such as a 50 watt amp. Not by much, but it will be louder. You can increase volume a few db by adding more speakers to the mix.

Thanks, I needed that

Here's a better angle maybe... which tone do you prefer? I personally have no great love for 10quot; speakers. Just don't do it for me. I like bigger ballsier 12quot; speakers, heck take it to another level, gimme a big old honkin' 15quot; JBL D130F! Got one of those in my Tweed Pro.

Find the speaker tone you love first, then figure out how many you can afford or actually need.

Rule of thumb is adding a 2nd speaker will usually gain about the same amount of additional volume as doubling the power.

Generally speaking, I think two 10quot;s usually seems louder than one 12quot;. But it depends on the speakers. Two really weak and inefficient 10's would not be louder than one really efficient 12...but two high quality and efficient 10's might be alot louder than one weak and inefficient 12. Lew

my follow up question will be: what tones do different speakers give? is it always the bigger, the ballsier?

thanks for the advice guys. i still have a few weeks to wait before the GMX112 shipment arrives so keep them coming.

Well, if you're looking at it from a cone mass perspective, the sound from a bigger speaker will be quot;slowerquot; while a smaller speaker will be quot;snappierquot; if playing the same frequency range. This is the reason why many speakers use multiple drivers because they're ability to move is different...well yeah haha.

You could always get a beefy 10quot; driver which would sound quot;ballsierquot; than a 15quot; one, just try out a 10quot; velodyne HGS/DD subwoofer and compare it to a normal one with a 15quot; driver.

the bigger the cone, the more low frequencies that speaker will 'attempt'. If it doesn't have the capacity to do so, because of magnet size or voice coil size, then those frequencies will fart out.

Smaller speakers tend to sound 'tighter' because of this-a 15 inch speaker will fart out more than a 10 inch speaker with the same voice coil and magnet size.
