Some random thoughts;
1. Zaph's opinions are based on driver tests, not subjective tests.
The Dayton RS series drivers hold a unique ratio of price to performance. While their performance does not approach European high-end drivers, it's not too far off and the price is a mere fraction.
These type of comments lead people to build the same designs over and over again in
cyber and they never explore other drivers.
For example,
"performance does not approach European high-end drivers"=
could be true
"it's not too far off and the price is a mere fraction." =
could be true
Or this can be way off in judgement.
The application plays a role in determining if the drivers are suitable. If you look at his
tests, some comments tell you to use the driver in a specific bandpass to get it to work
well. Duh.. what if I found a better driver what has a wider bandpass in spite that it
cost more? In that case for that design, the expensive driver can rule.
Zaph doesn't test for maximum SPL using a reference acceptible distortion level. What
about thermal power handling tests? There is more to driver tests than feeding it
1 watt and charting some data. People take these tests to heart way too much. They
are just guidelines to filter out the really bad drivers from the good ones. Others see
this as a precision test, I see it as s crud 'estimate' test because there is other tests that
aren't done.
2. People ask me 'if you know so much about this, why don't you start you own audio business' ? ... lol ....
a. Technically, I did have two audio businesses, but they were home businesses for fun
to try to make some pocket cash, to learn more about 'stuff', etc. Business is not my bag baby [Austin Powers]. I don't know everything about everything.... lol ... common sense
is your ally. Everyone can figure this stuff out.
... to continue.. Lets say hypothetically I wanted to enter the home audio market with
a speaker design that I would love to show off. It would be a floor standing tower,
3 way design. The subwoofer wouldn't be included.
Lets figure out how much it cost *you* for drivers in low quantity orders because these
speakers could be made to order - to keep your business model lean.
Cost for two speakers;
1. Tweeter cost: $1400
2. Midange cost: $300
3. Woofer cost: $500 - $1000 [uber woofer = $1000/pair]
Crossover parts: Lets use good parts, lets figure out $200.
Crossover PCB: You need to invest a few grand to have custom PCB's made, but
lets say $25.
So far, about $3000 just for drivers and crossovers.
How much is wood for this project? Depends, what type of wood, how exotic ? Lets
budget $500.
How much labor to make this? You hire a woodcrafter and he tells you he wants $25/hr
labor, 2 weeks full time to make this. $2000.
You are at $5500 in costs.
How much profit do you want for all your trouble ? Geeez... I want to make some decent
cash. I wouldn't mind making $5k profit for every pair of speakers sold.
Total cost $10,500
Dealer model: Your cost times two = MSRP
MSRP = $2099.99 //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
You walk in the store and way ' WTF ' $21k for speakers? The salesman lets you talk
them down to $16k/pair.
I make $5k profit, the dealer made $5.5k profit.
Keep in mind, speakers that cost $20k in the store won't have the level of
quality as this recipe I just mentioned, not even close. If I were to find a speaker
like this in the store, it would be in the $40k range easy.
/crazy/
That's why you see $1 tweeters in Klipsch, Polk, etc., low cost mainstream audio.
