Re: Phase Linear Andromeda Bob Carver Speakers & Subwoofer

That one cap will put the tweeter 90º out of phase with the woofer. If you don't care, neither do I.

Yes, it was the natural mechanical rolloff I was talking about. If you look at plots of response versus frequency, the curves tend to get ugly toward the limits of woofers.

The nice thing about passive crossovers is that you can decide where in the frequency spectrum you want the cross to take place (hopefully, a nice flat spot in the frequency response of both speakers).
It should sound like it isn't there!

"Yes, it was the natural mechanical rolloff I was talking about. If you look at plots of response versus frequency, the curves tend to get ugly toward the limits of woofers."

Hence the "requirement"/desire for a steep rolloff curve! And once the rolloff progresses several db, it becomes not too "noticed" even if a bit "erratic" (which I'm not sure this is the case with EPI woofer - have not seen any plots!).
But I guess if you had a musical note RIGHT at 1800 Hz (or whatever x-over freq(s!) your speakers have) for an extended period of time, you MIGHT hear some "distortion". But what are the odds of that? I'm sure if you put any system's response under a "microscope" for SOME frequencies. you'd see many "skeletons". But per usual, it's what your ears tell you for the vast majority of listening to the kinds of music YOU listen to that is the ultimate arbriter! Peace/Enjoy!

Re: Phase Linear Andromeda Bob Carver Speakers & Subwoofer

Too true. If they sound great, that's the ultimate arbiter.

Well I won them playing around with eBay. Now I have to pick them up. I did not really think that low of a bid would win.

Re: Phase Linear Andromeda Bob Carver Speakers & Subwoofer

Roy, thats great! What a deal, a set of these historic speakers.

I can't wait to hear your opinion of them & what they sound like.

It would be a real treat if you brought them to the fest. Maybe next year.

Congrats Roy!

Re: Phase Linear Andromeda Bob Carver Speakers & Subwoofer

congrats on the new set of speakers. Now you need to figure out what you are going to power them with. Any ideas?
Some cool Carver stuff!

Re: Phase Linear Andromeda Bob Carver Speakers & Subwoofer

Does anyone know the differences between the I,II,III? This version I'm picking up is version I.

Re: Phase Linear Andromeda Bob Carver Speakers & Subwoofer

Roy I know just what you need to do.

You need to pick up those speakers & bring them to the Fest!

Once there, Bob will be so happy to see them He will go through them to ensure everything is perfect.

We will demo them over & over & someone will offer you a great deal of money for them.

You will accept the offer & return home a hero with money for additional OCCD expenses.

This is an absolutly perfect plan.

NOTHING CAN GO WRONG!
