Suzy Chang build mistake

bobhowell · 15th October 2009, 01:41 PM

I am building Suzy but made one too narrow. Somehow the internal width is now 5 7/8". I am using 3/4 wood so I got one correct and messed up the other. I build these different from other folks and use solid soft maple. I glue the sides and top together and then add front and back. I can make the top chamber bigger if that is all I need, by say 1/4", but the throat will be off by a small amount. I can open it up also, if needed.

Suggestions.

So, I take no comment to be no one knows of a problem or how serious it is. I'll just leave it as is.

This is really a question for Scott... he is kinda scarce at the moment, his Dad is having health issues and his mind and his time is on that.

If i understand you, the cabinets in the pair are different? If they were the same i'd say try it and see how it works... you are off by 7%, the drivers can be as much as 10-20% out.

If they are different you will need to build another to get a matched pair.

Locating the two speakers in sonically different positions in the room will probably make more difference than that.

If I made that mistake I would build a new unit.It would drive me crazy just looking at them otherwise.

Bob, Scottmoose is the designer, he would be able to answer your question. Maybe pm him, he is an enthusiastic dude, and a great designer. Solid maple fronts, very nice

My 10mins of free time today is rapidly running out, but essentially the only way out is to build a new box. Sorry. The point that the room dominates down low & that driver variences are also wide is a good one, but it will likely still make an audible difference. YMMV -try it first & if you a/ can't hear a difference, and b/ can live with the aesthetics, then you've got away with it.

Expressed as a %, one is off by 5%. So, I don't guess it is significant. You can't see it. I'll move on to completion.

Thanks

Bob
