does yours have single coil pickups? mine has humbuckers so its a lot less harsh
ya.. its stock pickups in an older tele. if you have humbuckers then disregard.

Hey Andrew or Kevin.....or all nerds!!

http://edmullen.net/manuals/Shure_Vocal ... 300_ug.pdf
i use this PA Tower as a cab, is it 16 ohms?

so if i use this and at 8 ohm 4x12 whats my final load?

how do i run speakers in parallel?

looks like 16 ohms.

here's a site to help you learn load calculations:
http://www.tunemybass.com/bass_amps/how ... inets.html

(impedance of cab 1 X impedance of cab 2) / (impedance of cab 1 + impedance of cab 2)
=
(16 x 8) / (16 + 8)
=
seems to be 5.33 ohms to me. running them in parallel means plugging both of them into speaker outs on your head. this is the normal way of doing it.

5.33 ohms is not good for use with a tube head. do NOT plug these into a head that only pumps out at 8 ohms, it could seriously damage your equipment. if you have a head that can run at 4 ohms, it would be possible to run this load without obvious problems, though it's really still not that good of an idea if it's a tube head. you could get away with using a solid state head at 4 ohms.

Reece, how does that PA column sound for guitar?

it's rated at 16 ohms. you can also get yourself a multimeter and measure it yourself but 16 ohms is safe.

edit - 16 ohms and 8 ohms together will run at something like 10 or 12 ohms which can be a mismatch depending on your amp. some maps can handle these types of mismatch just fine(you may end up losing some volume but it won't damage your amp) make sure this is the case before continuing.

edit again - the above 5.3 ohms is correct. running that at 8 ohms on your head = burn city. bad news, running the head at 4 ohms should be fine.

I was about to lace into you for not knowing how to calculate parallel load.. your lucky. running at 5.3 is fine but you don't get whats called Maximum Power Transfer to your speakers meaning that your wasting some of the power.. most tube heads are very inefficient so its not that big of deal. Its always safe to run a load (speaker) thats greater than the output of your amp... the other way is when it gets dangerous.

As long as said load falls within the range that the amp is rated for (ie. don't run an SVT, which is rated to run at 2 or 4 ohms, with a single 8 ohm or 16 ohm cab).

Thanks guys.

How would I plug one cab into the next whats that called? series? whats are the pros and cons of that?
The shiiittttty solid state amp i'm using is rated at 4 ohms so i am fine for the time being, and the next amp im buying is a ZT which can only plug one cab at 8 ohm minimum.

I really like the sound, its noisey and really cuts through the mix. Might be time to retire it though.


So can i get tube heads that can handle 5.3 loads? or should i just get another 4x12

ya.. the further away the worse it is... I personally would only run matching loads on my amp head. its pretty easy to re-wire a cabinet to get the impedance you want. In this case.. re-wire the 4x12 cabinet to 16 ohms and run in parallel with the other 16 for 8 ohms. That is of coarse if your head has a 8 ohm setting.

yeah, rewiring the speakers in a cab should be just as simple as having a soldering iron and a screwdriver and you can get a lot of different combinations to reach the desired impedance. right? I've never actually done this but in practice it seems fine. and four speakers gives you the option of series, parallel, or combination (this is referring to the actual wiring of the speakers). I am all about matching loads as well. I've been lucky that none of my gear has had weird impedances. every guitar cab I've owned has been 8 ohms (two of them = 4 ohms) and every tube head I've owned has been switchable with 4 and 8 as options. yeah.

You couldn't practically/safely run the 16 ohm cab in series with another cab.

Yes, if you get an amp that can run at 4 or 8 ohms you can run a 5.3 ohm load at 4 ohms. Some amps are more sensitive to ohms matching than others.

What's a ZT?

A lot of audio guys sing the praises of vertical column speaker arrays, but they aren't very practical for transporting like a traditional 4x12 cab.

Not every cab rated for 8 ohms can be rewired to run at 16, it depends on what the speakers are individually rated for.

The ZT is a 200 watt single 12" speaker amp. They ruleeeeeeeeeeeee, you can plug it into an external cab with an 8 ohm minimum. its so light and easy to transport.

exactly... you would just need to open up the cabinet and see what ohm each speaker is rated.. although now that I think about it you may not be able to get from 8 to 16 as you likely have 16 ohm speakers wired series/parallel.

That's pretty cool, have you had a chance to play through one?

Ive gone like 4 times and played around with it haha. Have yet to run it through a 4x12 but the guy said he tried it and it ruled.
