Dean still working on crossovers?

Recommended Posts

Dean rarely responds to emails . You have to call him .

I would give you the number but Dean works at a place that harbors alien technolodgy .

I don't want to be vaporized or worse , sorry .

I sent him an email a few weeks ago (didn't know he doesn't like them) and haven't heard, BUT then in looking at some of his posts i saw where he said he was taking a hiatus to work on the house for awhile. Hope he gets that done so he can play more here with us.

Hope so.... After I recover from the economic "crisis" and my retirement payout will be above the level of a retired street peddler in Ethiopia..., I really want to sell off half the stuff I own and get a pair of Jubilees... and ask Dean to do a pair of passives....

Sorry guys, I just have too much going on in my life right now to give up time to crossover work. When I do have free time, I prefer to spend it enjoying my own system. As for email, I have it shut off through the forum, and I don't look at PMs. I've also stopped using my sbcglobal account, so if you've sent something there I won't see it.

Too bad. I should have done it when I had the chance.Would you divulge the resistore change so I could have it perfomred by someone else? Strictyl for personal use.....?

parts and a small value adjustment to a single resistor in the notch
circuit in the HF section reduces the ringing to an inaudible level."

Don't you know that all caps and resistors sound the same -- why bother?

Huh? ; )

"In
spite of being a great speaker right out of box, the RF-7 has some
ringing from both the underdamped cones, as well as in the treble
response from the horn's resonant peak. The combination of the better
parts and a small value adjustment to a single resistor in the notch
circuit in the HF section reduces the ringing to an inaudible level.

What I do:

I
desolder the parts, remove all of the old solder with braid, clean the
boards with denatured alcohol, and then replace the capacitors and
resistors. I use Kimber capacitors in the HF section, and Solen or
Dayton Audio in the HF notch circuit and LF section. The junk resistors
are replaced with Mills non-inductives.





Those who listen with the RF-7, and who are on a tight budget -- might
find the most cost effective improvement by simply tacking on a 10 ohm
resistor to the existing resistor in the notch circuit. You won't get
all of the benefits of the full package, but it would probably prevent
the tweeter from going shrill during some musical passages. At any
rate, I wouldn't hesitate for a second to buy a set of RF-7s and listen
to them just as they are. The mod is sweet, but it doesn't make or
break the speaker by any stretch of the imagination."

I did the resistor mod after listening to my RF-7's for about a year. It really does make a difference in the top end. I did my RC-7 also.

I am ordering Auricaps 5.000 µFd. 10% 200V 1.10 X 1.17 and 12.000 µFd. 10% 200V 1.40 X 1.53 to do the upgrades. What resistor should I use?

Buy six resistors:

(2) 1 ohm Mills (12 watt)

(2) 2 ohm Mills (12 watt)

(2) 10 ohm Mills (12 watt)

Parallel the 10 and 2 ohm resistors together, and insert in place of the existing 2 ohm resistor next to the 18uF capacitor on the HF board.

Ok thanks. I was looking at the pics of your modded crossovers, What capacitor did you put in the LF section? Also, is a 12 and 5uF OK to use in place of the 18uF that's in the HF section or is it better to get the 18uF 400v 1.93x1.95?

I have been fishing out in Montana for the last 2 weeks. Did Dean get rid of his Jubilees?

They're not in his signature anymore. [:^)]

Oh well, so much for next years email to Dean![:(]

I gotta know - What happened to those Jubilees?
