Double Diamond Electronics

Hi Folks,

Anyone here ever hear of Double Diamond Electronics? The reason I ask is that I ran across 4 model ss-00x speakers at a local thrift. The cabinets seem to be well made (1" mdf front panels) but at least one (and I suspect all 4) woogers need foam.

Any help at all would be greatly appreciated.

I thought Double Diamond was a strip club.

Thanks but in the case of the speakers, Double Diamond is a manufacturer.

The wife is gonna kill me

I stopped by the same Sally Ann today and all four speakers were still there. I asked how much, she said $30 for all four, I said but the wooogers need fixing so she says $20. I say sold.

I'll use these for my first refoaming attempt since they were so cheap.

I also decided to go ahead and buy them because of the comments made in one of these many speaker threads regarding small manufacturers and how there are some unknown gems out there and also the comments made regarding whether to buy based on build etc. My thanks to all those who contributed to my knowledge, my apologies for not remembering which threads or who. :thmbsp:

Once I calm the wife down :nono: I'll borrow her camera and post some pics.

More Info

I did some more digging based on the part number that I found on the tweeter and discovered that the tweeters are a Philips AD 0160/T8, also used in the Dahlquist DQ-10, and that Double Diamond was taken over by Philips sometime in the 70's.

The funny thing is, the Double Diamond trademark was primarily known for bowling supply machinery and electonics bits. See here http://strategis.ic.gc.ca/app/cipo/...685&extension=0&startingDocumentIndexOnPage=1.

The logo is identical to the one on the cabs I picked up except it does not say "Bowling Supply Ltd."

Pics to follow as soon as I pull them off the camera.

Firstly, really neat score. For $20 I'd be making it out the door with those. Good for you! :thmbsp:

Secondly, Since you got four of 'em, I say use 'em for a vintage HT setup.

Then go rent either Kingpin, or Big Lebowski, or both...

From the April 2001 issue of Bowling Digest, written by Mike Allen...

"The two biggest films that feature bowling are undoubtedly "Kingpin" (1996) and "The Big Lebowski" (1998). "Kingpin" follows Roy Munson (Woody Harrelson), a down-on-his-luck former bowler who apprentices a young Amish boy (Randy Quaid). The culmination of this odd pairing is a chance for Munson to defeat his lifelong foe, Ernie McCracken (Bill Murray), at the National Bowling Stadium in Reno...the best part of the movie is when the young, flashy Munson throws a strike that defies the laws of physics.

"The Big Lebowski," is similarly quirky but far superior, a movie where "the bowling team" represents stability for a special man, "Dude" (Jeff Bridges). This film will be long remembered for the scene in which Walter Sobchak (John Goodman) pulls a gun from his bowling ball bag to settle a dispute over whether or not an opposing player made a foot foul."

Additional bowling movies...

"Gangster fun: Both "Scarface" (1931) and "The St. Valentine's Day Massacre" (1967) feature a mobster being gunned down in a bowling alley. The moral? There's always someone who has had a worse day on the lanes.

Love and bowling: "Racing with the Moon" (1984) stars Sean Penn and Nicolas Cage, telling the story of two pinsetters who work in a stunning four-lane alley. With time running out before they are to begin serving in World War II, they deal with the ups and downs of their relationships..."That Night" (1992) stars Juliette Lewis as a teenage girl who falls in love with the counter boy at the local bowling alley. This story, set in 1961, features several scenes that take place in a large hopping beauty of an alley...

"Porky's," anyone? Maybe the last tiling you'd expect in a "teen sex" flick is bowling. Believe it or not, we've found two such films, "Nude Bowling Party" (1995) and "Sorority Babes in the Slimeball Bowl-O-Rama" (1988)...

Bowling ball as weapon: The most creative use of a bowling ball has to go to Janeane Garofalo in "Mystery Men" (1999). Playing The Bowler, Garofalo's crime-fighting weapon is the skull of her deceased father encased in a golden bowling ball.

We've managed to find some other mentions of bowling in films starring such notables as Kim Cattrall, Carroll O'Connor, John Candy, Jack Nicholson, Joe Pesci, and Treat Williams, as well as animated stars Mr. Magoo and Tom and Jerry. But while they all may have toed the foul line, so to speak, on film, we haven't seen their work yet."

Pics?

My PE order came today so I'll be foaming these puppies in the near future. Anyone want me to post pics? I've already got some naked shots. :thumbsdn: or :thmbsp:

lets see 'em

Pics

Here's the pics pre-reapir. I had to pull the side of one cabinet off to get at the drivers because the front panels had been screwed and glued plus the drivers are back mounted. I'm going to cut out the backs of the cabinets now that I know how they are put together. I should be able to do it with a razor knife and some sweat.

Note the mid isolation. The cabinets are actually pretty well made from a furniture making perspective.

By the way the mids are 5" and the woofers 10".

I included pic 6 only to show the switch.

To those with more know how than me, is a recap in order?

Very interesting, thanks for sharing and I'll be waiting to hear what you think of the sound. Those X-overs look like quality stuff to me, also very unique and cool baskets on the woogers. :thmbsp: Nice score, Jay

One pair up and running

I've finished refoaming and reassembling one pair and have given them a little break in period. I've got them in a small room (roughly 8x9) along with a pair of Polk Monitor 40's and I must say that the DD's have nice crisply defined highs and mids but the Polk's have the edge on bottom end and are much more efficient. For now that is. I've already noticed a change in the amount of bass in the DD's after about 20 hours.

Attached is a before and after pic of the DD woofer.

For the second pair, I have a pair of HPM-40 woofers that I also just refoamed and I'm going to try a side by side taste test once both sets are broken in. I've got one of these put together already and right now the old alnico DD's have the edge.

I also noticed that the DD's are more forgiving than the HPM's when it comes to refoaming- more room in the voice coil area. The HPM's have a little rattle so I'm going to try the rotation trick.

The baskets are the same as those used on the Turbosound TFM-202, a floor stage monitor http://www.noretron.fi/sendfile.php...78&PHPSESSID=211a0cc88f61f6c3987e799903140daa. I got a couple of these woofers from AKer ARRAY that I will fix sometime in the near future.

thedelihaus, your review of Bowling for Columbine?

A recent episode of House, M.D. also...

Thanks

Hi, I am very interested in your double diamonds, as I have just picked up a nice pair of sm800 that are in need of reconditioning. The boxes are mint, just the speakers. Mine have crossovers 12 inch woofer, 2 4.5 midrange and tweeter. Any information you may have found or do find, please let me know of the origins. If I find any, I will do the same.
Thank you.
