CDT Components are they as good as some people say??

I love my CDT CL-61a's. 120rms and they are definately worth the $100 I spent on them. I wouldnt hesitate to buy them again.

If you want some really nice clairty and can mount them pretty much exactly on-axis, then I'll recommend the Peerless/Vifa XT25 ring radiators to go along with the Exclusives mids. Cross them at no less than about 2500Hz with 12dB/Oct slope or around 2000Hz with 18-24dB/Oct.

knowing what i no and cruising around the diyaudioforums recently and listening to more and more systems of diff needs and wants, i personally would drop the 3 ways i have and go 2 way active from start. i wish i did.

i personally dont like my midbasses in hd642 set, 1st pair broke, new ones are loosening up lil to much.

But i wish i went with a rainbow set if i bought by same brand and i wish i did the peerless exclusive 7's with seas or ow1's.

So that peerless exclusive 7" must be a fairly well-known or well-respected driver in DIY components.

Yes, for both home and mobile audio applications.

Sounds like I could do a lot worse (yeah I sort of understand the specs, but going more on referral here).. A match up with that alum. seas tweeter I guess, with active setup with a cda-9887, aught to be serious bang for the buck.. given an adequate 4 channel for the fronts.. maybe a pdx or xa4000.

With a PDX-4.150 (or maybe even the 4.100) or an XA4000, you're going to have no power problems at all.

One thing I was wondering.. That peerless 7" is an 8ohm speaker.. Given the lecturing I've had from other guys about getting more power from lower impedence load, should I be concerned at all.. or play away happy as a lark on 8ohm mid drivers?? Typical for a home driver, but in car audio it seems the norm is for 4ohm or even 2ohm loads on individual channels off the amp.

I do also understand that some of the ICEpower amps don't bump in power depending on impedence drop from 4 to 2... don't know about 8 though.

Sorry.. don't mean to hijack the CDT thread..

Started my own on "DIY" drivers for lack of a better name:

There's going to be absolutely no difference sonically between a 4 and an 8 ohm driver from the same amp in the same configuration/install.

The equations work out the same regardless of impedance, and the industry standard method is to use 2.83V at a distance of 1M = measured SPL (in dB).

8 Ohm Driver

SQRT(Watts * Ohms) = Voltage

SQRT(1 * 8) = 2.83V

4 Ohm Driver

SQRT(Watts * Ohms) = Voltage

SQRT(2 * 4) = 2.83V

See? It takes twice the power to get the same measured SPL out of the 4 Ohm driver as it does the 8 Ohm driver.

So when you see an 8 Ohm speaker with a sensitivity rating of 87dB and a 4 Ohm speaker with a sensitivity of 87dB, you now know that the 4 Ohm speaker requires twice the watts to get the same result.

Don't worry about it being an 8 Ohm driver! It'll perform beautifully.

Understood.. That's good news. So I started up a DIY thread then naturally AFTERwards I searched.. It's obviously been way covered in here.. a good thing but a lot to read.

Lot to read yes, but a lot of good information to commit to memory. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Funny how more and more I recognize these drivers from high-fi speakers I've seen and heard.. Krell, etc that use sourced drivers instead of their own like Paradigm, B&W, Wilson Audio, etc. Seas and Scanspeak quite a bit, as well as Usher. Seas makes phenominal mids.. sorry I'll leave it for that thread.

How about this...you'll never see a car win a finals either MECA or IASCA using cdt....and you have to understand...that it fits a price point for them...I will say this to the day I die.... CDT IS HORRIBLE!!!!!

Must be a Missouri thing. I always thought CDT sucked as well. //content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif I could always find something better for the price.

Although...A coworker recently purchased some M6's and if looks meant anything these would be the most kick *** mids ever made. But 'll have to wait a few days to actually hear them.

lol....I had their flagship 7's to test...Horrible!!!!! but alas.....it's hard to convince people on the forum...in person is way easier when all I have to do is let them listen to my car //content.invisioncic.com/y282845/emoticons/naughty.gif.94359f346c0f1259df8038d60b41863e.gif
