it depends on what ohmage the speakers are.
Let's say you have two speakers:
there 25 watt, 8 ohm.
That means that wether you wire'm parallel or serial, the resulting cabinet is 50 watts.
When wired in parallel the ohmage is:
1/8 + 1/8 = 2/8 (then turn around, just lke resistors) = 8/2 = 4 ohm.
when wired in serial it is 8+8 = 16 ohm.
So if you get speakers there are 16 ohms, you can wire them parallel and you have 8 ohms!
If you have speakers that are 4 ohms: 4+4=8 ohms!
But if you have 8 ohm speakers, you can not make two of them become 8 ohms.

good luck! and remember the rule of thumb.
speakercabinet always have the same or higher ohms then the amp. then your amp will live longer.

and if it's half powered when it's plugged in a 16Ohm cab, it become as powerfull as the Tiny Terror..
I didn't explain it good enough, because i'm definitely no expert on this stuff and when it comes to power output its all very different.
I haven't found the info yet about this so here from the top of my hat.
Let's say you have a 50watt amp. and let's asume that it produces a maximum of 100dB of sound. let's call that the outputpower; the energy that you get out of it (all terms used here are just and only for this explanation).
The way sound works and dB's work is that dB is on a logaritmic scale. doubling the output power wil increase the dB with 3. so in this explanation when using a 100 watt, the maximum outputpower would be 103 dB.
That doesn't seem much, but it is a lot.
A normal band rehearses between 110 and 115 db or more. really loud bands hit at 120db and more. There are tables with the corrext listings.
A jetfighter at take-off hits 126 dB.
My band, for example, when measured, produces about 118 - 120 dB. But it doesn't sound as loud as an jetfighter taking off, not can we even with the amps cranked.
That's because of the logaritmic scale and because each soundfrequency has it's own dB sort of.
A low frequency at 100dB sound either louder or not louder as a high frequency at 100dB. Don't remember which.
Now... to create a low frequency, you need more power, because you need to move moer air. That's why a bass-amp is usually more powerful as a guitar amp.
The power rating on an amp show use the maximum power (but can also be rms or max power at certain frequencies), say 30 watts. its stand for the power (electrical, not sure) the amp has to drive a speaker to create the ar to move to create sound.
Yes, i totally forgot what i wanted to say.
But don't compare a tiny terror and a laney vc30 with thinking "if i connect a 16 ohm's cab it'll be an amp half as small".
because it's not like that, its way more complex. way more and then some.
And a vc30 with a 16 ohms cabinet will still be loud, you might loose some headroom, but that's basically it.
So forget the technical mumbo jumbo and trust your ears.
Oh and open up the vox cabinet to find out the ohmage of the speakers.
If it's a stereo cab with two speakers i thinkthere two 8-ohm's in them, and you can rewire those to make a 4 ohm cabinet.
Which fits the Laney.
Problem solved!
Why didn't i think of that before i wrote all of the above!
(I hope I'm using the good word.. 
)
