I just tried putting a 4ohm black widow in my twin reverb and it just don't sound as loud as I thought it might.
Have I pulled a boo-boo? I figured any ol 4 ohm speaker would do fine.
The sound is nice and smooth, but............
Might it be that the black widow needs more power running through it to really drive it correctly? I must admit I've never personally played a twin with a 15" in it, so I don't exactly know what to expect, but it don't sound as 'driven' as Ricky or lloyd.
Or I could be just a little paranoid and all is well. I just don't want to blow my amp up. I don't really have much but a somewhat "keen sense of the obvious" to work with here.
Any input would be greatly appreciated,

The Twin is designed for a 4 ohm load so the 4 ohm BW should be OK.
It's more efficient than many speakers so that wouldn't be a problem.
Perhaps it's just a bad speaker or it's not what you expected.
I had a Twin and replaced it with a 4 ohm JBL K130 (there weren't any BW speakers back then).[This message was edited by Jack Stoner on 11 October 2005 at 05:17 AM.] |

The Vibrosonic is designed for an 8 ohm load. Any Twin Reverb I've seen stock takes a 4 ohm load. You can do two speakers of 8 ohms to get a 4 ohm load. |

My Twin Reverb had two 12" 8 ohm speakers wired parallel and the OT was 4 Ohm. I replaced the 12's with one JBL 15" 4 ohm speaker and had not problems. It could be that someone has modified the amp for an 8 ohm load. Most TR amps I have seen were 4 ohm output impedance. I'd try another speaker. Also, it could be the OT.

So, were you expecting an increase in volume? Even though the 1501 is (was) one of Peavey's best (read: most efficient) speakers, it probably wouldn't sound any louder than the two twelves you're replacing. |

take it out on a job etc, give it some time, it should sound great with the Twin/BW1501 combo, my twin was a four ohm output, as stated above it probably won't be much louder than with the stock speakers but at the higher volume levels I think the BW will sound more up to the task. How was it to put in? It took me a while to place the speaker right as to not hit the transformer, but a nice mod to a great amp! |

What I was saying was that it actually seemed as if I had lost volume when the BW went in. The 2-12s were louder. and punchier.
I had lucked out and found a cabinet already done up with a 15" baffle, placed correctly, so it was an easy in/out.
I actually found a twin with the jbl already in it, so when it gets here, I can listen to the 2 amps side by side.
The one I have here now (w/2-12's) is a 1970 no master vol. that has been blackfaced. the one with the jbl in it that will be on it's way shortly is a 69'( no mast. vol.) that has not been blackfaced, although it has been "Sarno'd". I'm interested to see if I can really hear any difference in the two.
