Arc/Rainbow CAL 25 Tweeters

What's the lowest xover point for them? I'll be tinkering with my comp set by going active. The passive xover point is set at 3200hz but would like to know if it could go any lower with a 24db slope.

thats the whole point in going active, test test test. see how it sounds when crossed lower.

Yes that is true. I can't find what the frequency response is for them and I'd like to start as low as possible and then work my way up.

The Jersey boys should know...3.5max and 6spdcoupe are the guys that could help you with that. Nice tweets huh! Told ya //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Right on Fox, thanks. I'll shoot them a pm and yes, those tweets are awesome!

Test test...... but don't give them too much power at like 100hz ! //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I say with a 24 db slope start at ~2k with low to medium volume and pile on the volume slowly to see how they behave. If you are the type that likes balls to the wall loud listening level all the time then may 2.4-2.6khz is a safer point.

I had them in my car, with tweeter ear level positioned at 2.5khz 18/24db slopes with a 85-100 rms per tweet amplifier on them.

^^^ he always beats me to it. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif I definately wouldnt dip below the 2K range though.

I didnt realize you had em that high Manny, **** my memory is shot. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

As i understand it, a good place to start might be to find the Fs on the tweet and double it. For example if the Fs is 1000Hz, start at 2000Hz. I am learning more and more about this active stuff everyday, so someone please correct me if I'm wrong. //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

Ok, I'll start from there and see where it sounds best. Thanks for the advice!

Gotcha.

Ahhhhh, now that you mentioned it, I do recall about doubling the xover point at the Fs. Read it somewhere in some article, probably Autosound 2000 or some mag.//content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif

Speaking of A2000, wasn't there an article about tweeter protection while going active? I think it was some type of mylar cap going inline or across the terminals. Hmmmm .... someone help me out here.//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

A 20 +/- mF cap could be placed in line. Some people believe in it, others dont. Its used to absorb extra DC saturation coming from the amp. There are a few articles for this floating around on carsound.

Thanks coupe, I found the article at carsound and the formula to calculate the capacitor value. I'm not sure how many people do this but I just want to protect my tweets from pops and spikes.

Keep in mind adding a cap/filter inline will create an automatic 6db slope...so basicaly thats stackable to whatever slope you chose when playing with the xovers actively. So say you want to achieve a 24db slope, you really only need a 18db using the digital xovers on the HU. So in reality you have up to a 30db slope to play around with playing your tweeters lower.//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Manny,

So when one runs comps in passive mode, the passive x-overs will be stackable with whatever slopes I use on the H/U as well?

I'm still breaking in my Rainbow Profi Kicks but actually had an itching to try out the CAL26 in active. Just curious to see what sonic benefits over the already good x-overs. Would you also recommend the same x-over points as the CAL25 per the above (mine's in the sail panels and will be fed the same power via 4150XXK)? What bandpass settings would you recommend for the W 165 Kick woofer?

Also, I take it you and 6spd don't use the cap?
