molan Posted November 19, 2013 Share Posted November 19, 2013 Be super careful with a PF500 and any low impedance load. They have a nasty rep for going 'bang' at the slightest provocation A dead PF500 isn't the worst thing in the world but if you shred your speakers at the same time then it really won't be a lot of fun. Definitely make sure you have a separate DI option (like a little Sansamp pedal or similar) if you're planning on gigging the PF. Quote Link to comment Share on other sites More sharing options...
chris_b Posted November 19, 2013 Share Posted November 19, 2013 [quote name='Dropzone' timestamp='1384878394' post='2281778'] ....Having run just the S12 at low volume last night the low A was farting a bit.... [/quote] Farting at low volume won't be a problem with the cab, and not one that extra cabs will resolve. Quote Link to comment Share on other sites More sharing options...
RandomBass Posted November 19, 2013 Share Posted November 19, 2013 [quote name='Dropzone' timestamp='1384878394' post='2281778'] The footprint of the S12 is about half that of the Mk1 Compact. Looks brilliant together, If only I could work out how to add pictures. [/quote] This confuses me. I've owned a mk1 and mk2 Compact together, and an S12, and mine all had the same footprint.

RandomBass Posted November 19, 2013 Share Posted November 19, 2013 [quote name='brensabre79' timestamp='1384877870' post='2281770'] Well Pete, the 'mis-matched' 2x10 / 1x15 setup was indeed popular for a long time. As was the Laney Linebacker... Thing is, some of these were designed to work together. My rig with similar speakers was bi-amped with a crossover for example, and it worked brilliantly. but that does not mean that any old 2x10 and any old 1x15 will work well together, especially with just the one amp. SOME of the Barefaced modular series were designed to be used together or apart. The Super12 and Compact were part of this range, along with the Midget I believe... Having said that, I personally see no need for these sort of stacks unless you're playing in a stadium without PA support! To the OP. The Super12 will easily handle twice the power your Ampeg can muster. You can get the full 500 watts out of it just by using the Super12 on it's own. You'll get 60-70% of that with the compact on its own (8 ohms). If you use them together in series you will still get about 70% power. That's with all the knobs at 11 mind... So just use the Super12, turn it up so you can't hear every person in a 30 mile radius telling you to turn that f****g thing down!! [/quote] Pretty much it really.

Dropzone Posted November 19, 2013 Author Share Posted November 19, 2013 The farting was caused by the -15 db button being in. S12 definately louder than thecompact and shifts air nicely. Not as loud as my Mark bass and compact together but a much tighter tone. Still gutted i cant use both BF together. Quote Link to comment Share on other sites More sharing options...

LawrenceH Posted November 20, 2013 Share Posted November 20, 2013 [quote name='stingrayPete1977' timestamp='1384876866' post='2281753'] I have noticed that the resident experts on here are quick to tell everyone not to use mismatched cabs even though a 1x15 and 2x10 was a very popular rig for a long time yet the most popular mismatched rig I see now is normally some kind of Barefaced mountain of various cabs piled up with some on their side etc? [/quote] That's a different issue, we're talking running in series here - the impedance curve mismatch between the dissimilar drivers will Mess S**t Up. I agree that the theoretical problems of running different speakers (in parallel) can be overstated compared to real world situations. Sometimes it messes up the bass end, but even then you might not notice! The room will often do a lot more 'damage' to that region. Quote Link to comment Share on other sites More sharing options...

Conan Posted November 20, 2013 Share Posted November 20, 2013 [quote name='Dropzone' timestamp='1384897018' post='2282128'] S12 definately louder than thecompact and shifts air nicely. [/quote] You'd expect that because the S12 has two drivers and is a 4 ohm cab! The Compact only has the one 15 and is rated at 8 ohms - so will draw less power from your amp at any particular setting. They also have different voicings, with the S12 being (I believe) more mid-focussed. All of these factors make it seem louder and actually be louder. Why anyone would need more than a S12 is beyond me... sounds like there is a problem somewhere. It could be the amp, but it could also be something else.

[/quote] My mistake, meant with the button out. In my quest for volume, there is loads more without cutting but this seem to overload something either in either the amp or cab. Both basses I tried are active so it might be too much but even the E was farting without cutting it. However, cutting does remove a lot of the low end oomph, which makes me sad.

StephenYork Posted November 20, 2013 Share Posted November 20, 2013 So let's get all the info, you are using an active bass into a PF500 and a S12. The farting (when the 15dB cut is off) could be the amp clipping at the input stage, did it stop farting when you pushed in the 15dB cut?

Dropzone Posted November 20, 2013 Author Share Posted November 20, 2013 Yep, ;ooks like without cutting it the amp is being over driven. The clip light doesnt come on though but the sound is dreadful. Push the button in an it tightens right up but loads of volume disappears so have to turn the volume right up, but it stays tight.

barkin Posted November 20, 2013 Share Posted November 20, 2013 [quote name='Dropzone' timestamp='1384868403' post='2281597'] I have just purchased and Ampeg PF 500 and a Barefaced Super 12 to also run with a Mk 1 Barefaced Compact. At the back of the amp there is a speakon and jack output. With both cabs having speakon outputs. Does it matter which I run to which or is it all gravy? [/quote] No - electrically it's all the same, the outputs are parallel connected. Quote Link to comment Share on other sites More sharing options...
Dropzone Posted November 20, 2013 Author Share Posted November 20, 2013 I was hoping there was some clever circuitry that would allow me to run both but it would seem not. Perhaps I need something bi ampable or will I always struggle with two different impedence amps???? Size and volume (with a good tone) is everything ;-) Quote Link to comment Share on other sites More sharing options...
