Yummy!!!

i discovered a few things to work on with the stratus tonight (with the test disk).

my sub/mid integration needs a LOT of work, i don't know the exact freq cause i still can't find the details on the test disk i have, but one of the warble tones has a huge hole in it, i'm guessing its around 40hz but that's a total guess. It's loud both before and after but drops to nearly inaudible there. When i have more time that's hopefully easily fixable.

My door panels have two resonances, one in the 200-300hz range and another up near 1khz or higher. I knew about the lower but not the higher. I'm hoping solving that will help tame some of my reflection problems as well since they seem to be right around 1khz.

oh yea, center image sucks, i need to actually setup the time alignment

A hole is MUCH better than a peak. Either way I'd try and roll down the freq's next to it even if it means higher levels on the gains to compensate. Boosting with an eq has never given me results that I am very happy with (other than minor boost of course)

what i wish i was running...

h701 combo seems to be what i'm lusting after ATM

mdt-33s in the dash

7" nextels (damn you tom)

12" Q x2 in custom trunk molds

2x memphis belle (1100W/sub and bridged a/b channels for mids and tweet)

If you had an H701 and 2 belle's you should be in the 3 way world. Bridged belle for midbass and the other 4 chn for midrange and tweet. Then you need to up the 7" driver a notch, even though I LOVE the Nextels.

you americans and your v8 powered, rwd cars get all the fun

surprisingly, not that many of us actually drive V8-powered, RWD cars anymore

Nope but there are a chit ton of RWD V8 trucks.

Morning Adrian & Ramos!

Oh so tempting.

[ramos 2]

That is a pretty good price on a decent scope . I bought the same model about 4 years ago and paid $200 for it

[///M5 2,833]

I bought a real old school one at a Toro auction for $15, got a nice drafting table too. This was before ebay and craigslist so I am not sure how business's get rid of stuff now, but they used to just have little sales. I did cheat and had an employee buy it for me as there wasn't public availability.

You also get a free Digital Multimeter when you but that scope as well, not sure if its worth two chits, but its free.

mine is on it's way

didn't even try to talk to someone who works at a local radio station because i don't want a huge bulky scope...

Are these good scopes? All I've seen are ones that are $1000+ so are these pretty accurate? I really want a scope so I can see exactly what my amplifier is doing... let me know what you guys think.

They may only be 5% accurate instead of .1%, but for your purpose you really just need to see the waveform shape. The time clock may not be the ultimate in accuracy either, but again it will be relatively correct which is more than adequate for your needs. It isn't like you care if it reads 41hz instead of 40hz (when counting the time window).

In other words, I wouldn't worry about the accuracy. If it were a 10% device it would be fine. For your app, you really only need to see clipping and the waveform and neither matter that much on overall accuracy.

[///M5 2,833]

Now whether a cheap piece of gear is reliable and will last is another story. Who knows on that. If someone has had one for a while they could pipe in.

ok, that's what I needed to know cause there was a lot of specs that I don't understand. Glad you could decipher that for me

I'd like to know if Ramos still has his or not. 4 years would be impressive

Also, what attachments do I need if any? Wouldn't I need red & black probes for the + & - speaker terminals, or do you just use that single probe in the picture?

-John

[///M5 2,833]

I didn't even read the spec, just a generic response. As for the probes you really only need two unless you want to measure current (which it may or may not do) and then you would need a current transformer (CT).

[Adrian_D 520]

i think they supply both the probes

[Adrian_D 520]

someone was trying to talk me into buying an old scope. something like 2 channel, 20MHz bandwidth, but that would've been overkill.

i don't want to measure the slew rate and other stuff

waveform is enough

dbfan187 has one iirc

and lukas (audiojunkies) also owns a scope just like the one in the ebay link.

Gotta shower and get to the fair grounds
