SWEET JESUS! $50 an hour!!!?? if anyone is around me, and would like to get this done for free, let me know. i have access to a RTA and i have way more than enough reference cds to tune your setup well.
no problem. 12khz cutoff?? hmmmm, how did he determine this? if he used an RTA, which one. im pretty sure it did not register on the RTA. where and how is the tweeter mounted? i am assuming you are using the silk tweeter and not the aluminum. im pretty sure they can extend to at least 14khz and the slope should end at about 18khz or so. a 30band eq can somewhat fix that.
let me ask you this, how do you like your diamond speakers? if you like them, no need to change them. he is probably trying to sell you something. get a nice eq before you change speakers. a nice eq can do wonders for any speaker.
just so you know, on my Lotus tweeters, the RTA i used doesnt register anything past 14khz, but i can hear it up to 19khz. unfortunately, my ears cannot hear 20khz. use test tones to see if you can hear past 12khz. i am pretty damn sure you can on your diamond tweets.

not too sure what RTA he used. a BIG white one if that helps
- he used pink noise while using the rta - the tweeters are mounted right in frt of the speakers - please note this is not for my S (I've sold my S) but rather a 1993 Crown Victhe tweaters may not be Diamonds because i purchased them used from a member of new england and Kevin (the tuner) was not trying to sell anything - I asked what my next logical upgrade would be and he said a set of high end speakers (i may be able to get a set of Focals if one of our locals upgrades his set-up but all in all i do like the diamonds - bought them for $200.00 and because i had my system loud before i couldn't tell how good they really were but now they sound great..
I agree i should consider a good eq. because the head unit only has a five band eq.
Thanks very much for your feedback!!

$50/hour seems a might high to me, but value is in what the market will bear. all in all, i don't think it's outrageous, but...
either way, i'm glad you were able to have it done Steve.

If a speaker just can't reproduce a certain frequency (or range) how can an eq help the matter? Also, if the tweeters are not angled properly or don't have a good off-axis response I'd think there's not much you can do about it?

Really?

an eq can help because like you said, with a speaker that has poor off axis response or cuts off before 20khz, you can boost up those freqs that are lacking.
i also find a completely flat response on the RTA is overly harsh.
[QUOTE]hell, that's Dr. Bose's theory? if the speaker sucks -- get an EQ.

when comparing good quality speakers, they all have the ability to sound good or great when adding an eq. its like, when you take a listen on the demo board, most decent speakers sound pretty good or even really nice speakers sound great, but as soon as you install them into a car, it doesnt even sound like how it was on the demo board. main reasons for that is resonance, rattling, and reflections. this is were the EQ comes in.
- The woofers are aimed at your feet.
- The tweeters are placed too far away from the woofer.
- The tweeters are aimed at each, angled poorly.
- The left tweeter is too close to the driver's ears compare to the the rest of the drivers.
- Take a look at the stock tweeter grill - forget about any off-axis response!
You can use a 30 (or whatever) band eq and time delay to try to fix these problems. OR, you could start with good speakers, install them properly, keeping all above issues in mind as you place/angle them. There is a good chance all you'd need is a bit of time dealay (mabye a 5 band eq) and it will sound pretty good.
Just my $0.02

Does that imply: "Best speakers need no fixing..."

J/K
however, most cars are terrible sound environments, which is more of what you're fixing than the failings of good speakers...
