Greetings everyone; I have a pair of Yamaha SV 10 speakers for my band (yes, I know, cheap bad sounding speakers). We have a 6 piece jazz band that plays acoustical (including no amp for the bass and guitar) and the speakers are used exclusively for vocals. For our needs they have worked out great.
I noticed the other day one of the woofers sounded a little scratchy and was thinking since these are basicly the cheapest PA speakers Yamaha makes they probably have cheap components in them. I have been toying with the thought that I might be better off replacing the driver with a higher quality one than have the existing one re-coned.
I cannot seem to be able to find any of the specs on the Yamaha website; will I just have to measure the box and crunch the numbers? Or can someone recommend a good replacement speaker?
For what it's worth I plan on replacing the Piezo horn with a Compression Driver in the future also.
thanks
George

George:
New Woofer + compression driver (+ horn ! ) + time/labour to router out hole for horn to live in, Why ??
Cut your losses now, and just replace the box.

You forgot the crossover, a very critical part of the speaker, and by far the hardest part to diy. A compression driver will require a very different crossover than a pizza.
That puts you over $300 per speaker by your pricing, which seems about right. You could easily find something used that would be better than what you have now, and probably better than what you could cook up in that price range used.
A good place to find used speakers are the Music Go Round chain, and they might take your speaker on trade.
You can do some searching in the Lounge for endless discussion on the qualities of the less expensive options, but the best option is to play some music and sing through the speaker(s) you are interested in prior to purchase.
And you can't do that when you buy it one piece at a time.

...ooops. haven't used a (passive) x-over in over 20 years !
As I am not in that end of the pond, I was thinking more like 250-350 woofer, 150-300 comp, 100-150 horn + 2 hours (or more - any internal bracing that interferes with the new components ? )per box, plus 2 crossovers.
George: Like I said, I am not in that end of the pond, so I have no suggestions for you. By my thinking, 700 put into a refurb job (per box) is NOT a good investment.

Chris, valid point. Don't think I haven't though about it; unfortunately economics plays into the decision.
The way I was thinking I might spend $100-$150 for a good woofer; $50-$100 for a Compression driver and $20 for the horn (I own a router); could I buy a better complete speaker for $270?

George,
The numbers you are looking at spending on components will not get you very far, and you haven't thought about the crossover.
Put a WTB ad in the Marketplace with your budget.
Guaranteed you will find some used speakers that will be an upgrade over what you have.
As an example, you can often find Mackie SRM450's for around $300 used. They aren't my favourite speaker but at that price they would be a major step up and are self-powered to boot.
