Hello, I'm new to this forum and the audio world. I just hate the fact that there isn't a lot of hight end audio stores carrying any high end brand. I've purchased all my equipments base on extensive research and other audiophile's opinions. Ok, back to the subject, I've heard that the Scan Speak R2904/7000 is one of the best tweeters out there, it creates a smooth and liquidy sound. From what I've read at DIYaudio forum, other people called it "other worldly". I'm thinking ordering a pair of these, can anyone post an impression if you've heard it?

This is what I have:

Rainbow vanadium phase plug (haven't put it in yet)

Mcintosh MX4000/MDA4000

Mcintosh M431M amp (4 x 100 watt)

The question is, how should I set up the scan speak? Let me rephrase that, what is the proper way to set up these without blowing it? (it's just pricey!)

Uhh... Never heard it but heard decent things about it.

The proper way to set it up is to make sure that you are :

1. Not sending it too much wattage.
2. Making sure the wattage you are sending it is not clipped.
3. Making sure you cross them over at a decent enough point so too much low frequency isn't going to get to the tweeter...

hey man, welcome to the forums.

i think you'd be best to ask that question over at diymobileaudio.com. a few people have probably listened to the tweeter and its best to ask over here. not too many people on this site has even heard of scan speak.

Your in the CAR AUDIO SECTION...not the DIY take it to partsexpress.com

wedoca-DIY or ECA(Elite Car Audio) would be the place to ask. The majority of members over here are not running stuff like Scan Speak, Peerless, Vifa, Seas, Dayton, Dyns, DIYMA, Aura and others like these. There are some but not many.IMO

Do a search on DIY or ask the question over there.IMO

Indeed I do what I can.

There are some very knowledgeable people here on this forum. Most of them hide out and lurk around. It is too bad that there are so many n00bx who don't know their anus from their elbow... :fyi:

out of every tweeter I've owned/tested...

none have come close on axis...off axis it *****...

I could use any tweeter in the world and I'll choose this everytime and it is why it's in my car....I have 480 watts to each tweeter and they love it....

OK I am jealous. I really like the kicks, that is a lot of work to pull that placement off, I have to get started on figuring mine out. You fanning the fire. Really nice work. I would have to put something over them though or I would put my foot on them and destroy them.

Yeah that design has high frequency beaming like crazy. If you are sensitive to frequencies above 10khz those tweeters are a problem only being a few degrees off axis. Deffinately not car-friendly.

These are the exact same tweeters as yours?

http://www.madisound.com/cgi-bin/index.cgi?cart_id=4120449.13640&pid=1151
Just wondering why the different mounting plate, or whatever it's called. I currently have the morel supremo and hiquophon OW2 tweeters. I got 2 different tweeters because I'd like to compare the difference in sound, but am interested in the scan-speak also, since it is so highly regarded. However would need to have the round mounting plate so I could fit it in, and am wondering what the reason is for having the oval plate.
Thanks!


BTW here is the latest progress picture

The tweeter will go just above the midrange on the Apillar, angled in the same direction as the midrange.

His is oval because it is the modified driver from Genesis.

Ok, thanks! I guess Genesis will say they have improved the unmodified version. So that leaves me with a couple of questions.
Is their version regarded as better sounding than the unmodified scan-speak, by car audio buffs
and
What purpose does the larger oval plate serve? I would think that for some installs, a smaller round plate would make it a little easier to fit, so it must have some other advantage.

If I were to guess, I'd say it has something to do with baffle step diffraction...the same reason it's recommended to flush mount flanged tweeters in home audio cabinets, and speakers like the Cain & Cain Abby have their mid drivers mounted on parabolic baffles. Helps the frequency response...

Ok, thanks again. I read about flush mounting drivers but don't know about any of the other stuff. Will do some searching to understand better.

carpet on what?....the baffle has a layer of white laminate to match the subbox and amp rack...if that is what you are asking

the shape has nothing to do with baffle step...infact you can't flush this because the outer edge is beveled:pissed:....

it does how ever make it a ton easier to place in areas like a pilars and allow you to cram it closer to your mirange driver beacuse it's not a circle...

Ok, thanks for that. I guess I assumed it was close to 4" across the narrow part, but having a closer look, it's probably a bit less than 3". So I can see how the oval shape actually allows for a better fit in most car installs, also allowing it to be closer to the midrange.
From looking at the picture of your install, with the gap between your tweeter and midrange, it looks like the round plate could have fit in there just as close to your midrange, but in that case the round plate would have been right up against your midrange. I'm guessing that having the tweeter right next to your midrange wouldn't allow you to adjust the tweeter angle exactly how you wanted it, so if you had the round plate, it probably would have been about another half inch from your midrange. Anyway, thanks for clearing that up. For me, I'd have to use the round plate version so I could easily exchange it with the other tweeters.
