12 inch speaker work?

#2
it might be if it's sensitive enough and it can take that many watts (or close to it)
it would also help to put it up on something to help get it closer to ear level
or you could always convince your band mates to turn down :rolleyes:

This makes a huge difference, especially with larger diameter drivers.

You will hear it fine, but the band (read: drummer) won't. Too bad... turn down. Loud rehearsals allow the sucking part to be covered up. Try an acoustic rehearsal sometime... very revealing...

:D

We practice in a very large room. I use(for practice) a Behringer bx600 on an amp stand. It is turned slightly for the drummer's benefit and works fine. We practice at full volume through a PA/monitors. We are able to hear the bass OK without running it wide open. It saves dragging my bigger rig around. Your results may vary.

Hey, I'm wondering, would a single 12 inch speaker at 8 ohms be usable for a decently loud band practice if driven by 350 watts into 4 ohms?

Thanks.

Depends on the efficiency of the speaker/cab.

If you're talking about a SS amp, @ 8ohm your typical SS amp will give you around half what they're rated for @ 4ohm.
So expect around 175 - 200W into that 8ohm 12".

Something like a Bag End S12-D would work pretty well in that type situation -- others...I dunno (maybe an Aguilar GS112). [Uuuuh, those two together would be great -- 4ohm total load -- GS112=deep & S12-D=punchy.]

[Most tube amps have taps for 8ohm & 4ohm that both deliver the same amount of power.]

I had an swr bass 350 (into 4ohms, 2?? into 8ohms). I ran it into my aguilar gs112, sounded pretty loud, but like the other guy said you'll hear yourself fine, but for the band to hear you I'd suggest either more juice or another cab. I ran with 2 gs112s and the 350 and it was good for most of MY situations.

i use that combo quite often - it's what you thought it would be :D
just ignore the pesky s-15 in the middle

depends on the 12's, all speakers are diffrent[/QUOTe

4 into 8 is ok. 8 into 4 is trouble.

High Impedance output into a low impedance input
Distortion caused by the higher voltage,
Tone shift - tinnier sound - due to impedance mis-match.

Low impedance output into a high impedance input
Too little signal,
Muffled tone and accentuated bass.

Thus, we need to match the impedance of generator (source) to the load (destination). Often, a small mismatch will be passable, but the input impedance should be lower than that of the following circuit - i.e. Low into High will go, but high into low will not - damage!!

Particularly in the case of loudspeakers, an impedance mis-match won't do too much harm. But when feeding the output of a 100w amp into a loudspeaker you need to know the max power of the amp and at what impedance figure it's quoted at. Make sure your speakers can take the worst case - or you can blow your speakers (believe me, been there, done that!)



-it wont do any harm
