Step 2:Choosing Your Parts & DriversPlan, Canvas And Gather Information:Before you go crazy on shopping spree. Be sure to read more articles in the net, canvas more about their prices, read more reviews and take a lot of consideration inselecting brands. I'm a practical kid, I try to buy things worth my budget.

Speaker Drivers:To start off, Parts Express(online site) is a great source for speaker sales. Brands that I recommend buying are Dayton, Focal, Fostex, Seas, Tang-Band & Zalytron.

Try to find speakers that can reach a wide range of frequency. For woofers, a frequency response of 60Hz - 6kHz are good to start with. A frequency response of 2006kHz for midrange speakers and 4kHz - 20kHz for tweeters.

Remember that the human ear can only hear 20Hz - 20kHz of audio frequencies so don't get excited if you find speakers that can go above or below the audiblefrequencies, it would be a great impracticality.

The Crossover:Audio crossovers are a class of electronic filter used in audio applications. Most individual loudspeaker drivers are incapable of covering the entire audio spectrum fromlow frequencies to high frequencies with acceptable relative volume and absence of distortion so most hi-fi speaker systems use a combination of multiple loudspeakedrivers, each catering to a different frequency band. Crossovers split the audio signal into separate f requency bands that can be separately routed to loudspeakersoptimized for those bands.

As much as possible go for the bessel or linkwitz type of passive crossovers. They are the most common type of crossover filters, it has been and will always be thetrusted and safest.

Enclosures:There are two commonly used speaker enclosures, one is the ported and one is the sealed. The sealed enclosure is perfect for small speaker enclosures, it dampens sound given off, resulting to a punchy sound rather than the woofy effect. The cons: is that this design will require a 100% airtight enclosure for it to be effective. Theported enclosure is only ideal for large speakers (+ 6.5 inch").

My Speakers/ Drivers:Don't bother searching for my drivers, you won't find it. I have a friend who sells OEM speakers. According to the data sheets, this thing resembles the Dayton Audioclassic woofer, a veteran in the section of DIY HiFi, it was able to maintain it's quality over the years. You won't believe how much I got it for :D A pair was sold to me a1,600 php ($32), a real bargain! For the tweeters, I found mine from a local audio supplier, locally made, a brand that I trust. Again I got my pair at a cheap price of 500

php ($10).

Step 3:Planning The BlueprintsMeasure your speakers using your good old vernier caliper! Then write every measurement down on a piece of paper. Take note, you don't just make speaker enclosuout of random measurements. Calculators & formulas are required in order to design the perfect box. You will need to acquire your speaker's datasheet in order to desa proper enclosure. The links below are the sites that helped me learn building DIY audio enclosures.

The Calculators I Used:- DIY Speaker Enclosure Calculator- Speaker Enclosure O utput Calculator

Step 4:Marking The Soon To Be Cut WoodAfter finalizing the measurements of your enclosure. Get a long ruler and compass, use pencil to mark on the wood. As you can see, I used plywood in this picture sinmade a prototype before I made an MDF version.

Step 5:Use your jigsaw and cut through the MDF material. Also, don't forget to drill the screws holes where you wil l mount your speakers.

Step 6:Gluing The MDF PanelsApply enough woodglue to hold your MDF material in place. Bracings are added in order to reduce the amount of unwanted vibrations which may cause cracklings anddistortion.Also don't forget to use battens (1x1 wood) to firmly support the 90 deg. intersection of the MDF panels.

Step 7:Installing The Binding Post, Bass Port & Crossover1st.) Wire up your crossovers.2nd.) Screw you binding posts in place.3rd.) Use wood glue to mount and seal the bass port.

Step 8:Let Them DryIf you don't have the pressing equipment, there's always the mighty duct tape! Leave them overnight to dry.

Step 9:Apply Wood Filler Then SandTo achieve a flat and smooth surface, apply \wood filler in the gaps. Use your handy electric sander to smoothen the excess fillings.

Step 10:Chose & Apply Your Vinyl SkinHere's the hardest part for me (lolz), choosing the best skin for my speaker's enclosure. It would only lead with two options, to apply a sheet of vinyl wallpaper or do apaint job. I prefer a wooden finish so I chose the wooden vinyl skin.

Step 11:You're Done!Enjoy your music! Hey look it's my old kenwood automatic turntable. This is my simple room setup (@my bedroom) :D

Sorry for not showing the finished vinyl skin. This was a postponed project, actually.
