When you run a 100w amplifier head into a 4 X 12 cab like this, the power will be divided equally between them. So each individual speaker will get 25 watts. They are rated to handle 75 watts comfortably, so they will be fine. As others mentioned, you do want speakers rated higher than the amp. My 40 watt HRD has a 60w 12" speaker for a good example.

There are some basics about sound to understand:

1) Everytime you double the power (wattage) you get a 3 decibel increase in volume. This is just slightly louder, but perceivable. So, a 100 watt amp is just very slightly louder than a 50 watt amp, not twice as loud as most people believe. In fact, it would take about a 500 watt amp to be twice as loud as a 50 watt amp.

2) 12 decibels is considered a doubling in volume (twice as loud).

3) Two identical speakers in close proximity results in a 3 decibel increase in volume.

So, adding a 4 X 12 cab SHOULD get you about a 6 decibel increase in volume. This will not be twice as loud, but it should be noticeably louder.

However, this is a little misleading as well. If you have a 100w head with a single 12" speaker, that speaker is getting all 100 watts. But as I said earlier, if you go into a 4 X 12 cab, now each speaker will only get 25 watts each. So you lose a little bit with multiple speakers.

But all in all you do get an increase with multiple speakers simply because you are moving more air. And it will absolutely sound fuller. Multiple speakers handles deep bass better also because a single speaker can get overpowered by the bass and start to distort. The multiple speakers are sharing that power. It is spread out between them. So you get a deeper response without distorting. So this is one reason to use a 4 X 12, to get huge, but tight bass response.]]> Live Sound Wes Inman https://guitarnoise.forum/live-sound/stacks-cabinets-heads-questions/paged/2/#post-167564 https://guitarnoise.forum/live-sound/stacks-cabinets-heads-questions/#post-167500 Wed, 22 Mar 2006 04:03:39 +0000
i personally like a stack/half stack better than a combo amp because of 1) the cool factor (haha...sorry to anyone i offend but a stack is the classic rock and roll look) 2) the sound is a little bigger (not necessarily louder, just has more presence) 3) you can replace the head if you need/want to and can still use the same cabinet and 4) stacks/half stacks just have that "it" factor for me that combos don't (can't put my finger on exactly what it is).]]> Live Sound jtb226 https://guitarnoise.forum/live-sound/stacks-cabinets-heads-questions/#post-167500 https://guitarnoise.forum/live-sound/stacks-cabinets-heads-questions/#post-167131 Mon, 20 Mar 2006 22:24:00 +0000

on amps watts refer to the output of the amp. how many watts it can put out when you have it cranked to 10 and you are playing your guitar as loudly as possible through it.

therfore it iis as others have said. as long as your cab can take more wattts than your amp can you will be fine.

ALSO ALL OF THE ABOVE ONLY APPLIES IF THE CAB AND THE AMP HAVE THE SAME IMPEDENCE.
generally impedence is listed as ohms or as a little upsidedown horsshoey thing.

if the ohms don't match then things get messy/interesting/expensive/above my head.

hope this helps :P]]> Live Sound afterblast https://guitarnoise.forum/live-sound/stacks-cabinets-heads-questions/#post-167131 https://guitarnoise.forum/live-sound/stacks-cabinets-heads-questions/#post-167127 Mon, 20 Mar 2006 22:21:58 +0000
