| I have an old LA 400 Peavey amp with the Fox intense mod. Sounds great but the original 30 year old black widow speaker went bad. Amp a 200 watter like the nashville 400. I put in a Jensen neo-100 watt speaker as a substitute and to my surprise it sounds great at low volumes. Breaks up just right for the sound I like. I'm concerned tho I might blow it as its not rated for 200 watts. My question is can I run a 100 watt speaker in a 200 watt amp at low volume? Will it hurt amp? Will speaker survive? Thanks |

Here's the secret... don't lend it out! Should be OK if you can keep your foot out of it... step on the gas too much and you'll have problems. Big thing with neo speakers is overheating... the super magnets don't like it, and will lose their mojo quickly, followed by overheating and failure of the coil. If the magnet's not right, the coil makes heat instead of mechanical energy, then voila... crispy coil. That's why the neo's have the funny fins on them, heat dissipation.

Maybe put a load resistor in parallel with it...or put a fuse in line with it.
Its just electricity....circuit protection techniques abound. |

A hundred watts is a LOT of sound! As long as you're not playing with lots of distortion, or Chalker-like bottom end, the speaker will likely work just fine.
Keep in mind that a 200 watt amp is rated that high with all the volume controls maxed, and we seldom play that way. In fact, most steelers with 200 watt amps are seldom using with more than 50 or 75 watts! |

One secret bass players use... you can play speakers rated at less watts as long as you don't overdrive the amp... when you start making square waves, the coil spends a lot of time at the extremes, just sitting there... and the current doesn't go to moving the coil so much as it does to heating it up. Since the bigger amp has the higher headroom, you can get more from the speaker without stressing it as much as if you connected a 100w amp to a 100w speaker and crank it up into clipping.
Just don't lend it out and you'll be fine.

| Unless I misread, you didn't mention impedence of speaker. I'm running an Eminence Deltalite 8ohm in my Nashville, so the amp is putting out more likely 130 watts. Eight years still no problems. |

| If you're running the speaker into breakup, you may be putting it at risk. |
