Default 2 x 10 speaker ohm. help?

Right I guess this question is rather 'noobish' but here it goes. I have Peavey 210TVX. It has two 10" speakers and is rated at 4 ohms. However I would like the overall inpendence to be 8 ohms instead, as I would then be able to connect two 8ohm cabinets to my bass amp instead of just the one.

I know that I would need to change the speakers in it and I am therefore guessing that two 16ohm speakers would, when used in one unit take the inpendence down to 8ohms. The problem is I cannot find any 10" 16ohm bass speakers.

Anyway, any help would be greatly appreciated.

Thanks a lot

Chris.

I'm not very clear exactly what you're wanting?.

Presumably this is a combo?, and has two 8 ohm speakers in parallel to give full output into the resulting 4 ohm load.

You want to replace the internal speakers with 16 ohms ones, so it's a LOT quieter, and add an external 8 ohm speaker to bring the power back to what it was before.

Using four speakers rather than two will give a small increase in volume, but probably nothing worth all the effort and expense. Bear in mind the amount of power is still the same as it was before.

I would suggest building an extra cab with a slave amp built-in, and feed that from the combo - so you're getting a genuine increase in power and volume, and it's probably no more expensive than having to buy two new speakers anyway.

If what Nigel has guessed is correct, you can keep the drivers and wire them in series to make the cabinet 16 ohm. Then you can parallel the two cabinets to bring it back to 8 ohms. At 8 ohms it will only be 3 dB less than 4. But it still begs the question why?

Sorry, I don't think I made myself very clear

basically I have a Behringer BX4500h bass amplifier head churning out 450 watts. I have a peavey 210 TVX bass cabinet which is 4 ohms and capable of churning out 175 watts. I also have a Peavey TVX 115 which is 8 ohms and capable of churning out 350 watts.

I cannot use these together with this amplifier at present due to the ohm impendence being too low for the amp to handle. Therefore I would like to somehow make the 2x10 cabinet 8ohms instead so that both cabinets can be used simultaneously.

Any ideas?

You would need to replace the ten's with either 16 ohm ones in parallel, or 4 ohm ones in series. For a start you might try connecting the existing drivers in series to make 16 ohms, and see how the two cabinets sound together then.

cheers for the help. I have had a look but I can't really find any bass drivers which are 16 ohms. Also, if i wired them together to create 16ohms overall would that be likely to make the amp overheat or is it generally ok to run an amp on that.

Wiring them at 16 ohms will make the amp run cooler. It gets hotter when the the impedance is low and too much juice is being let out of the amp.

You want to paralel your 2x10" combo with your 15" combo ?


Tone Tubby can be ordered both 8 and 16ohm

But you might get an exstra amp cheaper, as suggested

Or wire the 10" in series, and then in paralel with the 15", as suggested
