I have 2 black widow 8 ohm speakers. I am interested in replacing them with 4 ohm speakers so my power amp runs cooler and more volume. There are so many models I don't know what to buy. Can someone help. |

What model are the 8 ohms?
What is your amp rating (ie: XX Watts into XX ohms)?
1203-4 (12") and 1501-4 (15") are considered "steel" models. |

All they say on the back is Black Widow Superstructure. There is no model number.. When I measure impedance I get 6 ohms. 6 X 1.3 = 8. So I know they are 8 ohm speakers. My power amp manual says
180 watts x2 @ 8ohms
180 watts x2 @ 4ohms
I spoke with the tech at Stewart and he said my amp (which has been running hot) would run cooler at 4 ohms. That is why I am asking. There are many speakers from peavey and was wondering if someone on the forum could suggest a model for me. |

Then if this amp is for steel and you want to stay with Black Widow speakers, you probably want the BW 1501-4. Peavey doesn't sell these anymore, but they come up for sale from time to time on the Forum.
You can, however, purchase from Peavey the 1501-4 Replacement Basket and a Neo Magnet as follows:
- Neo Magnet Structure - Item No: 00560870
- 1501-4 replacement basket (4ohm) - Item No: 00560140
The Peavey Item No's above can be ordered through any Peavey Dealer. The Neo mag can be attached to the replacement basket easily in about 5 minutes. |

The posting by C. Wagner pretty much covers the Black Widows for steel. I have a set of 1203-4 superstructures and they sound great, (with a Telonics rack) especially for E9. I also have a set of 1501-4's when I want to make a lot of noise.
However, I typically run one 1501 on the left and a 1203 on the right. The 15 on the floor and the 12" on a stand. Many people have commented positively on this set up.
I suggest you post some pictures of the back of the speakers, so the forum members can see what model you have. There is the possibility that you can replace just the baskets with 4 ohm models and save the cost of two magnets.
However, the new Black Widows baskets will not mount the old magnets. If you post a picture, forum members will know exactly what you have. Another idea would be to call Mike Brown at Peavey with your questions. He is very helpful and will know the answers instantly. The Peavey web site has their service phone number.
I replaced the speaker in a solid state combo amp with the 250 watt Sica speaker, 15" version, that Ken Fox sells and that works very well. Much lighter and enhanced bass, it is available in 4 ohms.

We have something in common. I run a Steel King or a Evans SE200 on the right . I use a Music Man with a 12" EV on the left. Both on the floor.
I always figured that I was hearing the Music Man and the crowd was hearing the Steel King. It takes a 15 a little more distance to sound right. The 12 runs out in about 10 feet. _________________ Bill |

4 ohm speakers draw more power and will cause the amp to run hotter (if we are talking about a transistor amp). Be sure the amp is rated for a 4 ohm load. I assume a stereo amp? Two 4 ohm speakers on the same mono amp would be a 2 ohm load, too low for a mono transistor amp (as most are rated 4 ohms, there are exceptions to that) |

What Ken says is scientific fact, Ron, I don't know what your amp tech had in mind, but a 4-ohm load will definitely cause more current to flow through your amp, generating more heat than the same rig at 8 ohms.
Are you certain that the amp lists the same power output for 8 or 4 ohms? Unless this is a tube amp with different tranformer taps for different loads the output should vary with the load. |

Well the technicians at Stewart Amps say the exact oppositte. They are telling me when an amp is rated for 4 or 8 ohms the amp runs cooler at the lower impedance and produces more power to the speakers. |

I called back to Stewart amps and the tech explained to me how voltage changes when the impedance is lowered. resulting in the amp running hotter. So I am happy you guys corrected me because i was going to buy new speakers and now iI won't. This forum is so totally cool. I just keep learning..... |
