15-20 watts + 30hz sine + pop can sealed enclosure = 4mm real p2p

DesertHeat sells these for $30 a set.

Enjoy.

these might work for an idea i had to make a center channel speaker to fit on top of an LCD monitor...

Effendi: The sound very nice to me, personally. Not much mid bass, but they're only advertised to play down to 125hz. I get a response that isn't harmonics at 30, but it's so little that you'd never hear it in a car. I ran them in my car for a while, I took them out because it looked horrible, and there were too many wires.

I painted the cans, naturally. The weird yellowish gook is actually a glue designed for carpet, it cured into something more like play-doh than glue. I use it because it's airtight.

like so? you would only get 10 to each of them though, cause they are 8 ohm

I also have much larger 3" versions that play to 80hz if anyone is interested. They can really ghetto bump for there size! The 3" is rated at 20mm peak to peak excursion, I have measured it more like 10mm, not sure were they got there #'s but even 10mm is crazy for a 3" driver.

Raven
12-28-2004, 10:47 AM
How much for those?

To use a pop can, you have to cut out the top of it. The big indent in the can where the lid attaches is perfect. The thin paper holdy things the mids come with can be glued in there, and then you just work from there.

Hahaha hey man good call, there is already line arrays from aura with these! They are not for sale but look really cool. For one of my home projects this summer I want to build an array with 30 of there 3" versions per tower! Matching them to some of there car audio silk domes that I have tons of. Very cool! Going to put them on my office matched to a trancendant T16 otl tube amplifier.

Are they anything similar to the small maybe 1" speakers that used to be used in the Apple g4 towers? We had a bunch of them in or publications lab...and had a little speaker mounted in the front for sound...i remember those moved **** far for like a 1 or 1.5" speaker. peace

This thing hit 4" peak to peak before long throw subs were even popular, they were sick! Put one of my old huge cell phones next to it to show how freaking huge it is, makes that crappy phone look tiny..

Who besides desertheat has some of these and can I ask you some questions. I actually have an imaging thread up that I had given up on until I saw these little 2 inchers, now I have some renewed hope.

So this is what I was thinking, I have MB Quart PSC-216's (discontinued Premium line with the 1" titanium tweeters) (http://www.mbquart.com/2003/en_US/products/prod_detail.asp?isArchive=true&cat=&series=premium%20series&strt=1&model=PSC+216) and I want to use the 2 incher as the midrange and relegate the current 6.5 midrange to midbass duties (say 80Hz to 275Hz). So these little two's would have to take on 275-2500Hz.

You guys that have these, can you tell me how they might perform in this type of situation? How are they working in your app and what is your app? Any comments or suggestions? I am only asking for your opinion becuase I am serously scroogin it and spending money is not going to happen right now so $30 or nothing.

that thing is so insane yet so awesome
the magnet is funky shaped

desertheat
01-02-2005, 08:22 AM
The mag is neo radial! In simple words strips of super freaking powerfull magnets about 4" long. The mag structure weighed about 44 pounds and the cone was held on by 8 bolts. The cone was field replaceable for concert use and of one cracked or blew, just unbolt the magnet and slap on a new cone! The magnets were so powerfull that one time I hade the cone detached and dropped a screw in the gap. I could actually pick up the magnet by holding the screw with a pair of plyers. Had to have a bud hold it down so I could pull it free!

If you notice the magnet structure on the huge 18", it is the same design as the ones on the mr62 speakers I sell. They are just tiny versions of that monster!

Ah you know that amp :) Yeah I have had my eyes on it for quite some time. I have the schematics to build it but I think I better get the kit instead. It is a thing of beauty. I am actually probably going to do the dual monoblock build from them! I cannot even IMAGINE the sound of an otl with 40 watts per channel, it is going to be insane!!! DROOOOOOOOOOOOOOLLLLL

If everyone else is wondering what we are talking about take a look at this page and these specific kits, they are AMAZING!

Yeah, I've heard of the OTL design, I don't know the technical details quite as well as some other types, but from what I do know, it's slick :) most of my tube experience has been with push/pull or single-ended triodes.

01-11-2005, 01:31 AM
no really though i was too stupid to make a pop can enclosure, so i used a 7x4x4 metal speaker box thing and just rigged them into there in a parallel config and plugged them into my home stereoon one channel, they sound ok for two inch speakers, but im not blown away, and now im not sure what to do with them, i really would like some headphones with them, but i dont have the skilles, they lack the depth of my other two way computer speaks, so they arent really an upgrade,,,hmmm any ideas?

brandontw
01-11-2005, 01:43 AM
yeah thats what im using them for ;) , my cheap shelf system thing is hooked up to my computer, and thats what i hooked them to, and they are on top of my monitor, so they are plenty close, but they arent in stereo, ill have to build an actual little enclosure for that. ill prolly give that a try

Raven
01-12-2005, 09:53 PM
Pop cans involve cutting the top of the can off. You actually get a lot of resonance, but it actually sounds *better* with it than without, IMO. It raises the frequency responce for the midrange like how a nice ported box does for bass.

Moe Lester: I was considering welding together some 1/4" plate steel for enclosures. I'd just have to cover it in p&s so the thing doesn't rip the metal box apart. =p

01-12-2005, 10:26 PM
i have the soda can enclosure, and i filled it half way with some expandi-foam to see if it got better response, and frankly i cant tell :p:

my biggest problem is that the reciever i have is turned up to 70 (max volume) and they arent to loud. so it looks like its only giving like 5w to the **** thing. and i also dont have any means of a crossover for it.

anyone know what i need to build to have a passive crossover from 250hz~2500hz or whatever they are spec'd at? cuz they play the high notes, but when they play the lower ones, the highs get really distorted.

any ideas?

Raven
01-13-2005, 10:31 PM
I found that 150hz works well. The light blue colored Stinger crossovers perhaps. I have them attached to mine sometimes. On and off, just trying to find what sounds better.
