Could house wiring affect the amp much? my house is at least 23years old and the wires are that old as well
If it is say a bias issue how hard is that to fix? My multimeter should be here by next week,
I'm not finding it anywhere as bad as my old Fender hot rod was. I think I can dial in a much better bedroom volume with the wizard than I ever could with the fender.
In fact I'm really pleased with the taper on mine
I was told that it hadnt been played for more than 5 hours.
So I'm not sure what the go was. all i know is it works amazingly now.
and clips arent going to happen just yet sorry, the rest of the family is home and somehow i dont think they would appreciate having the whole house shaking
Do I believe that speaker cone size factors into sensitivity? Yes! But the sensitivity of a speaker doesn't double because it's paired with another speaker. At "X" watts the speaker produces "Y" dB of output. I'm interested to understand how that can possibly change. I mean I understand phase cancellation and its effects on audible volume, not talking about that. What we are talking about is a measure of power being driven to a speaker load. If we are stating that the 4x12 will be 3dB louder than the 1x12 at the same nominal impedance (in our perfect world let's not forget) using my 64 watt example, then we need to figure out where the additional 64 watts required to squeeze out that additional 3dB is coming from. That or we need to figure out how passive speakers can create that acoustical energy on their own--independent of the power source they are hooked up to.
British Voiced meaning?
I hear good things about these cabs. I'm getting a 6505+ head.
I'm thinking of getting Afterburner 412B, Straight front. OR Mesa boogie 4x12 Stiletto (slant) cab
crap man you should have been here yesterday..or I should have said something. Today was the last day.
in a seven swampash h/s/h fixed bridge.
not yet. it'll be here in june.
I just joined the club.
hmm I'll have to run a test. what's your 7 string?
Well ok let's say I have one swamp thang rated at 150watts right in a 112. and 4 of the same speaker in a 412. Obviously if i'm 10-15 feet from the speaker it's going to sound louder out of the 412 because of where the sound is coming from right. But is there actually a pure volume increase?
damn - you just posted again. All I was going to say was shit bro you got all smart and shit on us
Erock has it right. There's a lot of variables going on here that make a direct comparison very very hard.
Still I find it hard that adding a single speaker would increase the volume significantly since you are cutting the wattage to each speaker and thus each speaker is working less hard as a result.
Everything I've heard previously on this forum is that adding speakers does not add a significant amount of volume. I haven't studied the subject so I won't talk too much. But assuming what was said earlier that "adding a speaker increases the volume by 3dB"; a 412 cab over a 112 cab is 9dB louder (which is almost TWICE as loud.)
Twice as loud is a HUGE difference. Thats about the difference between a 20w amp and a 200w amp.
I can tell you from experience that going from a 112 to a 412 does NOT double the volume.
I think alot of people in the thread are talking out of their ass, we need a legit psychoacoustics expert up in hurr.
Erock, holy ****! How've you been?
And me either. I'm dying to get my hands on one of those.
Yeah i was like.hmmm that must be him! haha.
Yeah you're not around much anymore. I"m sporting a JCM900 right now .
You make me sad that you got rid of your splawns
Whoa!!!! Erock!!! haven't seen you in like...ages...
Do you hang out on RT much? there is a guy by the name of Erock on there to
I see you have both a CCV and a Herbert.....how would you compare them? I have a chance to get either a CCM or CCV and don't know if it is worth it to buy it or even sell the Diezel.
and im sure all the "cheap meters from radioshack" in the audience will be congradulating the TS on how loud his amp was at his show.
Thing is, 4x speakers wont move more air than 1x speaker at the same wattage, assuming linear efficiency,
The single speaker will move 4x as much as the four speakers, and so move the same amount of air.
My amp actually sounds quieter through a 412 than through a 212
^See page 1 of thread below.....I think this is accurate but damn it sure is hard keeping up
PS: Erik, someone else here recently got a Wizard - I think that is documented on the last page of the same thread.
Just sold both my Mesas, so debating on a few things ATM... I messaged you on AIM the other day but you didn't answer, you bum!
How are those Tung Sol EL34Bs different from...say...JJ ones? Jw.
The Tung Sol EL34B is a tube i've been looking at. Considering how much I love the sound of my amp with the old EL34's in it, new ones might just be all I need.
A Fabled Erock appears!
FWIW, I was running a pair of JJ KT77s in my Traynor YCV40T for a long time. Never had any problems.
I say go for it.
I've definitely heard that the JJ's are a little less than reliable so I'm a little hesitant because of that. I like power tube saturation, too, so maybe it would be better to stick with EL34's? Also, to clarify, my power tubes are old but my preamp tubes aren't. I changed those last year. Are there any other companies worth noting that are currently making the KT77's besides JJ?
all else being equal - an additional speaker will add 3db.
where the fuk have you been brother
and why of all the threads did you decide to post in here
Good to see ya
Yeah, all this "percieved volume" crap. If it SOUNDS louder to the human ear, it's louder. That's what volume is. Take the "human ear" part out of that equation and tell me if there's any volume at all.
all things being equal 4 speakers versus 1 is an issue of dispersion rather then absolute volume.
If you have 4 speakers of the same efficiency through a 100 watt amp then each speaker is getting 25 watts at x sensitivity.
If you have 1 speaker then that speaker is getting 100 watts at x sensitivity.
It's impossible that the 4 speakers will receive more output wattage then the 100 speaker.
The issue is dispersion. It all depends on where you are measuring the perceived volume. Are you inside the cab? to the side? on the ceiling? A 412 will move more air so it will seem louder closer to the cab but since each speaker is receiving less wattage the strength of the sound coming out from each speaker will disperse and interact with the sound coming out with the other speakers differently.
If you have 1 speaker in the middle of the room it's going to sound quieter at the extreme left and rights of the room. If you have 2 speakers in the corners it's going to sound quieter in the middle.
So I've had my 5150 for about a year and 6-7months and I think I'd like to get some new tubes. I dont know how often you're supposed to change them but I'd like to get some just in case. So I was looking on craigslist(as I always do) and I found this guy who's selling a shitload of tubes. But i dont know which ones to buy, so if you guys could help me that would be cool. Here's the link...
It's about half-way down where he has the tubes. I've got money so I'm not really worried about that but I dont wanna' spend like 50$ for a tube. So how many of which ones should I get? This dudes got alot and I think 5150's have 7tubes.. I think, not sure. Any help is appreciated.
