Thunderbird Club

I have a 4 ohm GK Neo 410 and 2 X 8 Ohm GK Neo 412s- gives me lot's of flexibility.

When I was first trying to get my head around ‘the ohms thing’ I was told there was less noticeable volume increase (improvement?) by using the 1x 4 ohm cab vs 1x 8 ohm cab; more by just using 2x 8 ohm cabs and that the 2x 4 ohm cab is ruled out on many amps.

Then of course there are those Hartke cabs that are switchable between 4 & 8 ohms.

I finally decided that I wanted to build towards the Bassman 100T with 2x Rumble 115s. Which went out the window when my Eminar arrived. Seemed pointless to have 2 100w valve amps in the house for a hobbyist.
But you never know what will present itself at an opportune moment in the future. Just needs to be wide enough to sit my amp/s on top. :)

Speaking of Hartke... what kind of reputation do their cabs have? Been trying to research them online.
 
Backing off the GAS...
I dropped into South Austin Music today just to see what they had. They had a nice, red Epi TB for $500. Pretty but not the red I want.
Then I found a sweet '67 (IIRC) Gibson TBird for $7500. I didn't even play it because I didn't want to fall in love. I dig this store because they always have cool old stuff (a bunch of old Fender amps, an old SVT. etc.) but I'd love it a lot more with a spare $20K in pocket change.
 
The New Cataldo Plan For World Domination (or Damnation, take your pick). Apologies to 'The Brain'.

One cardboard box, rained today.

One quality part, burn the rest. Cat-with-no-tail-who-lives-in-a-Tree don't care, ain't putting no mackerel in his bowl.

Some high class components.

etc...and...

EfSoBird!

Also be a P version. Both with front or back electronics cavity, paint or stain, body wood, neck, and hardware options, etc.

'Research' says there'll be interest in the GP for something like this after the VP's success. Lull offers similar but at a higher price than I'm seeking.

Am I outta the Club?
 
The rule of thumb is +3dB everytime you double the drivers. The ohm rating on a cab tells you nothing other than the load which is presented to to the output stage of the amp.

You can wire 4 8Ω drivers to present 32, 8 or 2 ohm loads, ie series, series-parallel or parallel.

Now, if we ignore the cabinet ohm rating (not relevant here) the SVT112AV cab (single driver version of what I have) is rated @ 96dB for 1W in. The SVT212AV is rated @ 99dB -- you see, double the drivers gives you another 3dB for that same 1W in.

If you were to add another SVT212AV (yes please), you would get 102dB for that same 1W in. We can go from 1 driver to 4 drivers on the same amp and get an extra 6dB output, which is noticable, bearing in mind twice as loud is +10dB.
