I recently sold the chassis of my Nash 400.I'm using the cab with a JBL D130F,to go along with my Musicman amp(head).Instead of taking the old baffle out,I cut a 1/2 inch piece of ply and glued/screwed it to the old baffle,traced the hole and cut the 15" diameter.The baffle thickness is now over 1 ".Does that matter or will it affect the sound?-----Thanks,Jim |

I removed the 15" speaker from my Nashville 400 and made a new 3/8" baffle board for a 12" speaker BW 1204-4 and screwed the new board directly to the existing board.It sounds great to my ears. |

Thanks Len,I basically did the same thing ,but used 1/2 ply.Now my baffle is 1/2 plus whatever the old baffle was?(3/4).Thought I read somewhere that the thickness of the baffle plays a part in the sound.Not sure if that pertains to open back cabs or not.--Jim |

I went with a 1/2" baffle as an experiment, my theory was a resonating baffle board, my Taylor is as light as a feather with a thin top and rings like a bell, I like the thinner baffleboard better |

The original Fender Bassmans have a very thin speaker baffle, a lot of people think that has a lot to do with the way they sound. Like Jim said, the baffle itself tends to resonate. I have a '59 Bassman and you can actually flex that baffle with your hand. It must be 1/2"? I've never measured it. On the other hand, those original Jensons are very light, I'm not sure how a heavy modern speaker (like a BW) would work with a thinner baffle. Seems it could easily warp or sag over time. |

I think in General a 1/2 baffle is to thin. It flex's to much as well as resonates to much. This would cause the cabinet to loose deffinition. 5/8 and 3/4 seems to be a better choices. To thick and the cabinet can no longer resonate at all. You really need something in between.One side note is how big the cabinet and baffle are. Meaning that on a 12x12 inch baffle board, the 1/2 would probably be ok. But in a cab that is 20x20 inches, the 1/2 baffle would be too flimsy. Joe |

For sound accuracy (flat frequency response) you want as little cabinet wall or baffle resonance as possible, for example with hifi speakers and PA speakers. Any audible resonance causes the speaker to sound cheap and boxy. For guitar and bass speakers, accuracy is less important than getting a sound you like. Some people like a little "boxiness" enhancing the sound, others don't. Generally, the baffle is about the same thickness as the rest of the cabinet. |

Yes, every aspect of the design effects the sound, ie; speaker, baffle, type of wood, eq type, etc.. That's one of the reasons why a lot of R & D goes into a product during its initial design.[This message was edited by Mike Brown on 02 November 2004 at 11:04 AM.] |
