    As you can see the port has a corner in it, this isnt idea but well worth it to get the lowest possible response. What your looking for in WinISD is a flat response with the lowest response you can get. Its a pretty advanced program so you are best off watching a few videos online. Remember the volume of the port is excluded from the volume of the box Add port volume and box volume together then calculate dimensions.

    As pointed out in the comments wall thickness of the port as well as a rough estimation of the volume the driver will take up need to be taken into account and a not part of the "Box Volume" WinISD will give you. Next the cutout for the speaker needed to be made along with the terminal for the back of the speaker.

    I used neoprene as its super cheap as a gasket for the speaker which I just cut out with a stanley knife, thsi gives a air tight seal around the speaker and the box.

If I had more materials in a perfect world I could have designed the box to hit a bit lower than 32Hz but hey. Lots and lots of wood glue then left in clamps overnight. I opted for no nails or screws just to make my life easier when i came to painting and it seems to have done the job perfectly.

    After it had been routered it needed to be sanded, I used a palm sander with increasing grain sandpaper until it was as smooth as I could get. Primer First of very many coats then after so much hassle and a fair bit of shouting the paint was done to an acceptable level Used black automotive spray paint. It was a real bugger to get a nice smooth finish on this but I'm pretty happy with it, the finish really relies on the primer.

    You're best off doing a coat of primer, leaving it overnight sanding then repeat this with finer sandpaper until the finish is smooth to the touch. This should give a nice gloss finish after a few coats of spray paint.Setting up a proper home theater doesn't have to be terribly expensive or complicated.

    If you're still watching TV on a tiny screen and crappy speakers, it's time to upgrade. Here's how to set up your first real home theater. There are a few basic components to any home theater setup.

    In this case, when we say "home theater," we're not talking about putting a full movie theater in your home—though we've shown you how to do that before —we're just describing what your home entertainment system will be like when you're finished: multiple devices, an awesome TV, great speakers, all working together in harmony.

    We're going to assume you have a few things already, like a game console, Blu-ray player, or a cable box—the stuff you're actually going to hook up to your home theater. Our home theater will be a little basic after all, these can get really complicated if you have the budget and the spacebut it's a good start if you don't have much gear. We'll tackle how to shop for the best components without breaking the bank in a moment, but for now here's a quick list of what you'll need:.

    Now that we have the general components you'll need, let's look at each one in detail, along with tips on how to shop for each one. Buying the right HDTV isn't difficult, but it can be easy to buy more than you need because you think you have to have p video or a 60" screen.

    The most important things that determine the type of television you buy are the type of video you plan to watch and where in your living room you plan to put your TV. The farther back you sit from your set, the less your eyes are able to tell the difference between p and p. If you're sitting really close to your set, 60" may be simply too large for your eyes to absorb, but if you're sitting really far away, you're not getting the benefit of real p video.

    Don't get seduced into buying them just because they're there: If you already have a game console or a cheap set-top box that you use to stream video, buying a Smart TV may not make sense.

    Voice and gesture controls are cool, but if you have a universal remote or connect other devices to your TV it may be useless. No 3D movies? Don't spend extra on 3D.

It's easy to get seduced by stats like raw power, HDMI inputs, and add-on features like AirPlay support or Pandora streaming when you're shopping for one. Here's the bottom line: look for the features you need, and no further.

    For example, if you don't have iOS devices or Macs, don't get stuck paying more for AirPlay support, something many manufacturers charge more for after all, you can often add those features yourself for cheaper.

    If you don't plan to hook your home theater up to a set of 7. There's something to be said for futureproofing, but if you're not planning to upgrade and make use of the features in months don't bother.

    Remember: Electronics prices always go down and new models of everything are released every year. Stick to reputable names Denon, Onkyo, Marantz, Pioneer with well-regarded hardware, and make sure you research specific models before you buy them to make sure you don't buy something with known issues some of our more seasoned readers may have great suggestions in the comments, too.

    If you have older game consoles or peripherals, make sure your receiver can support them before you buy—it's easy to assume that any receiver will be a snap to configure for an old PlayStation 2, but that may not be the case depending on the cables you're using a problem I ran into when I set up my receiver. Check out this buying guide from Digital Trends and this article at Crutchfield for specifics on the specs you'll see while shopping for receivers and what they all mean and more importantly, whether they're important.

Will you have to run cable to get your speakers where you want them? Do you have furniture or other decor in between you and the speakers, or that you have to work around?

So, do you need a preamp for your home theater? Based on the many different home theater systems available today, the need for a preamp is dependent on three main factors.

    The first applies to existing home theater systems. If you have a receiver, it is unlikely that you will also need a preamp. If you do not have a receiver, the answer depends on how many sources you will need to connect to. Finally, you also need to consider the sound quality you desire. When I first began setting up my own home theater, I found myself constantly trying to figure out what pieces I needed and what worked together best.

    Depending on your desired usage and outcomes, as well as your space requirements and personal taste, a preamplifier may be a necessary piece of equipment for your home theater system. But what does that really mean to you? A preamp is used to connect multiple source components, such as your compact disc player, DVD player and Blu-ray player to a single output signal that can be controlled through an amplifier. We will talk more about the differences between the preamp and the amplifier later.

    When you use a preamp to do this, it allows you to switch between each of the source components seamlessly, with no need to disconnect one device to use another. As stated above, the preamplifier turns multiple input signals into a single output that is sent to the amplifier. The amplifier, in turn, then sends this signal, as well as the necessary power to produce sound, to your speakers. It should be noted that both the preamp and amplifier will need their own power sources.

    They are separate and distinct devices that often require the use of the other to produce a rich, quality sound. As such, if you opt for a preamp system, it is essential that your amplifier works with your selected preamp.

    Now that you understand what the purpose of a preamp and amplifier are for your home theater system, you may be asking yourself why you should or should not invest in one. By opting for a preamplifier set up, you will need to pick and choose each component for use in your home theater system. From the preamp and amplifier to the speakers and subwoofer — every aspect of a home theater system will need to be carefully selected. For those looking to go beyond the standard 2.

    In fact, depending on the device you buy, you can expect even an channel set up to produce crystal clear sound steadily.
