Topic: Special 130 - Hi and Lo inputs |

Hi all.
I have a Special 130, Ken Fox modded, with a Eminence speaker. I love it, but sometimes during gigs, i notice that i get some saturatione on the signal, probably because I go full down with volume.
The Special have not Pre Gain, only a volume (I use the clean channel). My Carter has a SS10 pu that is really hot, and normally I use hi gain input on am to have more volume.
Have I to use low channel and keep up volume on amp, or use something in between amp and volume to put a little down the volume of the steel? or an impedence adapter? or something else?
Thanks!
Matteo

Matteo I have found that if I open the volume on the amp a little more than I would ever need and then play on the back of the volume pedal I eliminate the overdrive of a hot pickup.
In addition while playing on the back of the volume pedal and with plenty of head room on the amp I get much more use of the pedal for swells and sustain.
Just a thought
Michael

| It is possible that you are heating up the voice coil in the speaker, have you considered a JBL or other high-effieciency replacement? The K130 puts out nearly twice the SPL per watt over the Eminence. |

The commonwealth speaker has 250w on 8 ohms, I think it's correct

Should be a 4 ohm speaker. You would be suffering a power loss at 8 ohms.

I have a couple 4ohm Scorpion's that I really don't need. Both in great shape if you want to change. One of the Scorpions came out of a MX that I bought. I found a 1203-4 BW and put the amp back factory. The two scorpions have the 200 watt magnets on them. The baskets are the same, 100 or 200 watt.
Just a thought.

I tried out some other speakers in my Sp130 the other day and was surprised by two things:
1) The stock scorpion speaker sounded better than anything else I tried (albeit, some of the others were 8 ohms)
2) The stock scorpion is light as a feather! Probably @ 4 lbs.
This is a great little steel amp, but, as with most 1x12 options, lacks bottom. Perhaps a bass speaker or ev or such could fix this, but the amp is already crazy heavy for its size: hate to add weight to it.

I tried before and after changing, the power loss is really little.
I tried pushin up volume on amp and staying low on VP, seems to be better..

Doubling an amps power will only result in a 3db SPL change in volume, the least change the human ear can perceive as a change. Typically it takes 10 times the amp power to double the volume of an amp.
Running the amp at 85 watts will clip a lot sooner than at 140 watts.
Unlike teh N112 amp at 80 watts, your amp does not have Peavey's DDT compression. that keeps the N112 from clipping by compressing the signal when it hits 80 watts. Your amp at 85 will clip and there is nothing to stop it. Running it at full power will result in more headroom in the amp.
You could well run an 8 ohm extension and get the full amp's power. Another advantage with the extension speaker is 3db SPL increase in volume. |

The power rating of a speaker has nothing to do with its efficiency, Matteo. You can have a 600W 8-ohm speaker with 89dB sensitivity and a 150W 4-ohm speaker with 103dB sensitiviy and the 150W unit will be significantly louder - more than twice as loud in fact - in the same amplifier, the difference being that you can blow the 150W unit much easier if you drive it with a 300W amp. As Ken's amps deliver 130W solid power to a 4-ohm load, any of the K or E series JBL's at 4 ohms will increase useable volume levels at the same power over anything Eminence, Celestion, Jensen or most any other manufacturer can offer.
If it's light weight you want that's another matter, here we are discussing compression and/or loss of power at high levels over time, thus my suggestion of a more efficient driver. |

So... have I to put again on the stock scorpion? or something else new?

| Don't you have any JBL speakers in Italy? Find a used K120 or K130 for that baby and you'll be glad you did, really! |

Ken, any SICA speaker suitable? Or other suggestions?

I'm picking up av EV 12L soon. I'll let you know how it sounds with the Sp 130 (that is, if I can still get to my laptop after I lift the thing and break my back!!)
