Mesa Boogie experts? Help me identify this 1x15 and its Ohmage?!

    Hey guys, I just landed a SWEET deal (UK£150!!!) on a used Mesa Boogie 1x15 cab! :hyper: :D

    The approx dimensions of the cabinet are:
    Height: 23.5" (60cms)
    Width: 19.25" (49cms)
    Depth: 17.5" (45cms)

    The cabinet is black and sealed (with just a small recessed jack input hole in the upper back) and the front has the dark grey wide-spaced diamond grill with the Mesa/Boogie logo in the top left corner above the 15" speaker. There is a 2" deep bass port along the bottom of the cab (under the speaker) and on the cab sides it says MESA on the handles.

    I believe it to be a 1980's cab with an EV in it (any way of knowing the era and the speaker make?) but I have NO IDEA what ohms it is....

    I am concerned as to whether it is a 4 ohm cab or an 8ohm cab (or even 2ohms!?) as it will affect what cab I can use it in conjunction with and whether my amp will handle them....

    Thanks for any advice that can be given.... I believe someone on this board is from Mesa/Boogie?!

    That *should* be an EV speaker at 8 ohms. Best way to check is to take it out and look at it - there will be a marking on the frame telling you what ohms it is. It's possible for it to be either a 200 or 400 EV as well, so check that while you've got it open.

    I'd be ignoring my educational duties if I didn't point out that there's no such word as "ohmage", the term you're looking for is "impedance".

    Lesson over, let's go get a beer! :hyper:

    Back in the 80's, this was an actual exam question in a "Physics of Sound" course I took in college. The correct answer at that time was that it was a misuse of terminology, and that the proper engineering term was "impedance". Curious as to whether this has changed since then with the dictionary, like the addition of the word "ain't".

    Because the English language is always in flux. Makes it pretty hard to learn if it's your second language, and we Americans don't make it easy on foreigners since we ain't too keen on learning other languages. We're lazy, you know.

    I'm waiting for them to add "nizzle" and "shizzle" to the dictionary.

    Thanks for the ohmage/impedence info.... :) I may *try* and take the grill off and speaker out to check it....yikes! :eek:

    Oh and thanks (I think!) for the English lesson, but 'English' and 'American (corrupted) English' are two different languages..... and being 'English' myself I'll use 'ohmage' and/or 'impedence' as being in 'common' use :p
     
  9. If you can get your hands on a multimeter ( maplin UK sell a digital one for £2.50 ) you can plug a lead into the cab and measure the impedance in ohms approx value to tell if 4 , 8 or something else by putting your test leads across the other end of the jack lead.

    Note if you are going to open up the cab some are front loaded, more often they are rear loaded so you may need to take the back off, depends on brand etc.

    Was this the cab on ebay recently ??

    £150 is a great price hope it sounds nice, what amp you going to use with it ??

    Cheers for the Maplin suggestion. I may try and get one of those Multimeters today.

    Yes, it's the cab that was on there recently. Got a great cash deal on it! :)

    I'll be putting my Tech21 Landmark 300 Head or my Ampeg SVTIII Pro through it and may combine it with my Hartke XL410 or Harkte XL4.5 for aural destruction! lol! :smug: :D
     
  11. The correct term is impedance which takes into account reactance and inductance in addition to resistance. A speaker is not a static resistance, hence it has impedance.
     
  12. Make sure you get the digital Multimeter from Maplin not the needle analogue type. If you are putting it with the SVT111 pro make sure both cabs are 8 ohms so your total impedance will be 4 ohms when used together.

    I saw that on Ebay looks great deal, well done
     
  13. Just checked with Maplins they have 7 hundred in stock : £2.99 each, good luck

    I bought one of these today and tried it as you said but it didn't register anything at all! Are you sure you can check the impedence of the speaker cab by plugging the speaker lead into the cab and putting the test leads on the other end of the speaker lead? :confused:

    I've taken the speaker out to try and find out the impedence. Please see separate thread and help if you can....

    "correct term" and "no such word" are not the same thing!!

    Thank you 'supposed language specialists' for the hijacking of a serious thread... :meh:
