Hello everyone

I have just recently acquired a sweet used Hot Rod Deville 410. I noticed you can power an extension cab along with the amps regular speakers. I was thinking about adding 1x12 to hopefully give it some more low end range. I'm confused as to what ohm speaker should be right.. And any recommendations on a type? Anybody pair a V30 with there's? Eminence? Any info on this matter would be most helpful! Thank you!

Turn up the bass control. The 410 Deville has almost 3 times the cone surface area that a single 12" speaker has. With 60 watts, it is capable of tremendous bass response on its own. Adding an external cab will not make the bass go lower in frequency, it will just be boomier.

The manual might just have that info. :wink:

When in doubt, whip it out.

I recently got an Avatar G212H cab which I hooked up to my 410 DeVille III at last Saturday's gig. The cab has Celestion Creamback 75w speakers.

The difference was amazing. The amp sounded 500% better. I think those that implied you could get more low end just by turning up the bass have not actually tried adding a cab.

The cab you add has to be 8 ohm. That means if it's a 1x12 it has to have an 8 ohm speaker. If it's a 2x12 it needs two 16 ohm speakers wired parallel (which mine is).

Also the cab will need at least a 60w rating (twice the wattage it will getting). It would also be best if the additional cab had speakers that have a sensitivity rating of 100 or slightly over. That way the 4x10's won't be drowning out the added cab.

So if I'm correct then one Vintage 30 should work fine. I do love the Creambacks though, and think they'll give you more low end.

You do not understand the statement that was made.

I said "Adding an external cab will not make the bass go lower in frequency, it will just be boomier."

The lowest note on the guitar is 82 Hz. The resonant frequency of the Creamback speakers (of most guitar speakers, in fact), is 75 Hz. In a closed cab they may go lower in frequency, but there is no frequency content below 80 Hz (unless you tune down or use a sub-octave pedal, in which case a lower resonant frequency would be preferable) that is going to drive them. The additional surface area will however make the bass louder. In other words, adding a cab will not give you useful bass below 80 Hz with a guitar, but it will make that 80 Hz sound louder. So will turning up the bass control. With my 5F6A Bassman clone, I have to keep the bass control set to 4 or less when the volume control is set to 6. Any more bass with the volume turned up higher will shake the walls and everything in the room.

+1!

And any extant sub-harmonics below 82 Hz are likely to be inaudible since such frequencies are typically -10dB or more due to a speaker's (any speaker's) inherent design.
