CL Score - Peavey Data Combo!

jimmyb · #1 03-14-2013, 01:28 PM

Just purchased off cl philly for $100. Peavey data combo circa 1987. 450watts into a 15" black widow. Loud as he'll, and just as heavy!
Can't wait to hear it in a band setting...

All the USA Peavey stuff is fine, You got a steal on the data-Bass. i have played through those and they got the stuff.

Wouldn't touch their imported stuff, though.

Buy American.

I would had a hard time not buying that myself!

looks like it's in killer condition too!

Just a reminder ... if you push those amps somewhat hard ...you'll toast the speaker ...

Thinkin about adding an extension cab out to it so the 15"bw doesn't have to handle it all?

Do NOT try to add an extension cab! The internal speaker is 4 ohms and that amp should not run into a 2 ohm load.

A better approach, IMHO, which I have done: I put in an 8 ohm BW speaker with the same T/S parameters as the original speaker. So now the amp is only putting out 300 watts or so into the single speaker (still more than adequate) and now I can plug in a second 8 ohm cab if I wish.

i use to own one of those. It was nice for the era but as you said heavy as hell.

@ nashvillebill
Can i run an external jack and connect a 4ohm cab or do i have to change the internal speaker to a 8ohm?

4 ohms is the minimum, which gives you an option. You can run a 4 ohm cab only if you wire the speaker out to disable the internal speaker when connected. Or you can wire it to run in parallel with the internal speaker, but you'd have to swap out the internal speaker for an 8 ohm and run an 8 ohm cab. There are other options, but they'd be non-standard and would likely cause confusion.

Nashvillebill's way of doing it is probably the best. Finding an 8 ohm Peavey driver shouldn't be too hard.

Well, you could disable the internal speaker and connect a 4ohm external cab. But then you'd be toting along a lot of weight for nothing!

By changing to a 8 ohm internal driver, you get the best of everything: a loud amp when used by itself, with a little bit more probability of the speaker holding up, and the option of adding an external 8 ohm cab without disabling the internal speaker. Cheapest way to do this: since this is a Black Widow, you unbolt the magnet and bolt it on to a 8 ohm replacement basket.

And you could (but nobody does) set it up to run in series, and run a 4 ohm cab in series, so it was an 8 ohm load. You'd (probably) still get more usable, non-speaker-toasting volume that way. I've given this some thought, as I also have a 4-ohm Peavey combo, and they come up far cheaper than new speakers do on a regular basis. At least for the LF end where limited speaker Xmax is the killer, you'd not be anywhere near the limits of the amp even at 8 ohm loading...

And, if you got 3 more 4 ohm cabs, series - parallel for the 4 ohm win -)

And you could probably STILL blow the speakers without the amp breaking a sweat. Limited Xmax is a female canine. On the other hand, you get nice SPL out for watts in, so if you remember that the point is to make noise rather than to spend as much wattage as possible on making noise, it can still be a win...

And another option no one has talked about yet is to just give it to me problem solved sir

Yep series could be done with a switching jack. I hate using switching jacks though, especially when handling power. Or use a toggle switch that would shunt the jack.

Note, the internal volume of the Databass cab is pretty small for the driver, meaning it sacrifices really low performance but yields a midrange bump. It's also bottom ported, so you'll get better response on a solid floor rather than carpeted. I recall putting some spacers "under" the feet (between the feet and cab) to boost the cab up another 3/4 inch off the floor since some places had carpet.
