PA Speaker hookup

[tle4]

I just got some old Black Widow Peavey SP2 cabs and Peavey Black Widow 118d
cabs. Can anyone give me some info on these cabs. The back of the SP2's say
150 watts max 8ohm and the 118d's just say 8ohm. How many watts do these
things handle together?

I also have questions on how to hook them up. On the back of the SP2's there
is a crossover there are two jacks that say full range and two jacks that
are under bi-amp marked high and low. I figured out that I can connect a
line from the amp to the full range side then run a cable from the other
jack to the 118D. How would I connect the speakers with the bi-amp side.

Thanks

When using the cabinets internal crossovers there are a couple of
different ways of doing things. Which way you do it depends on your
circumstances. If you come from your amp > SP2 full range > SP2 other
full range > 118D then you will get a full range signal to your SP2's
(including the low frequencies). If you go into your 118d first then
it depends on the internal crossover of that box. If it has an
internal crossover and a high pass out then the SP2's should be linked
from there. If it has no crossover then you will still get the full
range to your SP2's. Running the LF through the SP2's will reduce
your headroom greatly.

For the biamp operation. You would require 2 amplifier channels to run
the SP2's. one to run the mids and one to run the highs. You would
also require an active crossover before the amplifiers to split the
signal to each amp up. there are various benefits to doing this, it
gives you more control over the various components. However with doing
this you would also be advised to run a separate signal to your
118d's. This means 3 amps and a 3 way crossover. This is the obvious
disadvantage to this setup.


Unfortunately i cannot give you any information on the driver in the
118d.

It's a disadvantage in terms of expense and complexity, but there can
be a substantial improvement in sound quality and output..

As far as the 118D goes, it appears to be a 4 ohm sub with 350 watt
rms handling, 700 watts program. 49Hz -3dB point, 31Hz -10dB point.

Mine are older than 2004. I think they are from the early 1980's. The Mains
say 150 watts max 8ohms and the subs just say 8ohms on the back.

I dont think we want to go with a 3 amp setup. These are going to be for our
band doing local gigs.The less equiptment we have to hook up the better.

I am still looking for specs on these cabs. I guess I may have to call
Peavey and see if they can tell me.

So, get an amp that delivers 300w into 8 ohms, and you'll be good
to go on the mains. What more do you need to know?

The SP2s have two separate inputs for the purpose of running them
in bi-amped mode. In order to utilize that setup, you'd need a
crossover and another amp. I am not familiar with those cabs,
but I'd say it's a safe bet you cannot feed your subs off the SP2s.
You will probably need another amp and crossover, to get any
use from the subs. Simply jumping another cable from the full range
jack on your top cabs will send full range info to the subs, and
create a 4 ohm load that will want a lot more power.
Some subs have a built-in crossover, and an output labelled
"full range". Sounds like yours do not.

You haven't mentioned any amps. Do you own any, yet?
If so, what are they?

I have a Yamaha emx powerd board that has 3 different output settings
100watts x 2, 300watts x 2 and 500watts x 2. We also have a crownCE2000. We
will use power from one to power mains and sub and other to power monitors.

You fail to mention which one.

Your best case scenario would be to run the subs off the Crown,
and use one channel from the EMX for mains, the other for monitors.
I still think you really need a crossover, and another amp.

Yes, it's nuts to drive the subs and top cabs both full-range.

If the amps in the EMX have inputs on jacks then you can easily add a crossover
into the scenario.

So get one amp with a built-in x-over, run one 300W side high-pass to
the mains and the other sub-out ch to the sub. Lot's of MI amps have
built-in x-overs. Mackie and Yamaha come to mind, I don't think the
Behringer's have one tho.
