This is a transcription of a YouTube video on how to rev up your vintage stereo speakers without having to tear your stereo components apart. You will not need to hack your speakers apart, plus you save money, too! Thanks, Wired!

Today we are working on an econo way project which involves updating vintage speakers with more modern frequencies.  The benefit of the flat curves instead of the roll up highs of this old speaker.

 

The parts that you need to buy are Old Speakers $20 Crossover kit from Zilch; Selenium D220Ti Compression Drivers, $80 a pair; and, JBL Pro Wave Guides, $20 a pair.

 

The other great thing about this build is you do not have to hack apart your speakers. You can just set it on the top.

 

This is a compression driver.  This is a wave guide, it is a modern horn.  It features constant directivity, this runs right on the back and then this gets installed inside of your speaker or on top of your speaker.

 

These crossover boards are available from Zilch.  So let us get to soldering.  Let us start by installing small components first, so we are going to stuff the board real quick. I am putting these leads through the board and bending them back to hold the component in place.

 

So I am just going to go ahead and solder them into place .  Keep  in mind while you solder you might want to work fast, so that you do not inadvertently pull these metal bits off the board with the tip. It can get stuck and then the project will not work. Here is the work I just did.

 

Clip the leads.  This Zilch board is great because it bi-ampable, you can use more than one amp to power the bit for the woofers and one amp to power the tweeters.  Then just install these jumpers now so you can just run it off of one amp. 

 

And I just made these jumpers from the leads that I clipped off. Let us keep stuffing this board.  And the reason we are using double adhesive tapes on the board is because we do not want these parts vibrating.

 

Let us install the inductor.  If you are stuck at any point, you can just refer to the installation guides that came with the parts or you can go to the Wired forum.

 

Leads need to be stuck a little bit so they make contact on the board.  You can see this copper coloring on here.  We need to strip that away so we can make a proper connection on the board.

 

I need to install the inductor which also needs stripping.  This inductor we get a zip tie.  Next we solder the lid to the woofer and the wave guide.  I had these connectors earlier to save a little bit of time.

 

Here is our completed crossover.  This separates the signals, lows to lows, highs to highs.  It protects the highs from being destroyed by the full signal.  This will be a good time to test it.

 

This compression driver is then mounted on this cheap $10 JBL wave guide.  Our crossover is together and we just need to connect to the input terminals to the crossover.  It says in and connect the speaker cables.  We are in business.

 

Right now we are connecting the board to the input terminals.  I bet we can easily screw in on the back of the speaker for easy access to the speaker cable.

 

And the test works!

This is a complete transcript of Manny The Movie Guy's review of the movie Terminator: Salvation at YouTube. He was surprised to find that the movie fared well, despite the absence of Arnold Schwarzenegger and original director James Cameron. If you guys still remember, it was the Terminator movies that launched Cameron's film career. As an act of desperation, he sold the script of the first Terminator movie to Hollywood for only $1. The movie of course went off to make box office history!

I was prepared to hate Terminator Salvation. How can director McG top the stellar productions of the first two Terminator films by James Cameron? Besides, the third movie of the franchise was a forgettable mess.

The writers of the third Terminator, John D. Brancato and Michael Ferris, in an attempt to erase that movie from our memories, also wrote the fourth film. And now, Brancato and Ferris are forgiven. Terminator Salvation is a worthy addition to the franchise.

The best part of the film is its Western structure. Terminator Salvation borrows myths and conventions from good, old Western films in order to come up with a flawed but ultimately satisfying movie.

The film is set in the year 2018. Judgment Day has come and gone. Now, an army of Terminators roams the desolate, post-apocalyptic landscape. But small groups of survivors have organized into a Resistance. Their would-be leader is a man named John Connor (Christian Bale).

The character John Connor has been present in the last two Terminators. Edward Furlong played him as a young teenager in Terminator 2: Judgment Day and then actor Nick Stahl in Terminator 3: Rise of the Machines.

In Terminator Salvation, John Connor accepts his heroic destiny, but he must first come to terms with Marcus Wright (the fantastic Sam Worthington), a new Terminator prototype that is part-machine, part-human, yet whose heart is all intact.

Adding layers to the narrative is the character Kyle Reese (the charming Anton Yelchin). You may remember the name from the first Terminator played by Michael Biehn. In the 1984 movie, Kyle came back in time to save Sarah Connor, the lovely Linda Hamilton, and became the father of John Connor. Now, Kyle is a young member of the Resistance and is about to meet his son for the first time.

Terminator Salvation is a story about three men who must find common ground to take a stand against Skynet, the artificial intelligence network that is increasingly hell bent on unleashing nuclear annihilation. Like a Western film, the women in their lives are either genteel (Kate Connor played by Bryce Dallas Howard) or rough and rugged (Moon Bloodgood as Blair Williams).

Director McG once said that he offered the role Marcus Wright to Bale but the actor declined and chose John Connor instead. And that is a good thing because the character was given ample focus. The bad part? Bale seems to be stuck with his growl and scowl acting he perfected in the Batman films. He wasnt able to add gravitas to the role.

But the savior of the film is Worthington. The Australian actor is the heart of the movie, literally and figuratively. He gave a memorable performance as a conflicted Terminator who must choose between following Skynet or saving humans. Worthington is also cast to play Perseus in the upcoming Clash of the Titans remake, so this actor’s star wattage is poised to shine bright.

Yelchin is also a great addition to the cast. The guy who played Chekov in Star Trek is stepping yet again into mighty big shoes. But he proved to be such a charismatic actor that he embraces the Kyle Reese character and makes it his own.

McG did his best to create a summer popcorn film and succeeded! Terminator Salvation has great special effects (watch out for those giant Terminators and their robot motorcycle siblings) and cinematography. From the first time you see Marcus boots in the foreground with a decaying Los Angeles in the background, you’re entering desolate American west by way of post-Apocalyptic future.


The film has some glaring plot holes but I wont spoil the movie for you by spilling them here. But there is one giant surprise that I cannot keep from you. There is an homage given to the original Terminator, Arnold Schwarzenegger. And you will find yourself clapping with joy.

And for that, Terminator Salvation gets 3 the-franchise-is-back kisses!
