DIY Speaker Build

I’ll mark the placement of the woofers, tweeters and air tube being sure to stick with the exact placements as in the instructions. We have previously shown you a DIY effort from Klipsch Forum member Jonathan Wood who created a Frankenstein-version of the Klipsch KPT-904 cinema speakers This time, we’re turning to fellow Klipsch Forums member Steve Bedard who created a similarly monstrous speaker that utilizes a K-402 horn and borrows elements from the elusive Klipsch Belle speaker.

Woodworking skills are required to construct wooden enclosures (e.g. for speakers), with some enthusiasts going beyond traditional woodworking to CNC lathing, and luxurious veneers and lacquers Room acoustics solutions are also popular among DIYers, as they can be made with inexpensive and readily available insulating materials, and can be dimensioned to fit each particular room in a precise and aesthetically pleasing way.

Now all you have to do to complete your speaker cables is to terminate them with good spades or bananas , like those from WBT, Furutech or Eichmann Make sure that you note whether the solids or striped wires are positive polarity and and be consistent with your other cable channel or you will have your speakers running out of phase with each other.

You see, I have designed and built the best DIY speaker i’ve ever heard.and it’s one of the best speakers I have ever heard, regardless of price.and it’s efficient enough to work with low powered SET amps, even in large rooms.and it’s very easy to drive, with an impedance curve that doesn’t drop below 8 ohms.and in its basic form is one of the cheapest hifi speakers available.and it can be built with no experience, and minimal tools.

While we were at it, we sanded the PVC piping, then painted it with a Satin black to give the stands some contrast. Since subwoofers are usually self powered you don’t need as powerful an amplifier for your main speakers either. Rockler Woodworking and Hardware is selling both DIY Bookshelf Speaker Kits now. Alternative: Instead of creating your own, you can hack apart existing speakers.

One good example of a spherical speaker is the Gallo Nucleus Solo above on the left which is made of rolled steel or brass. Make 2 monoboxes In each, connect only one channel (left or right) of the input jack directly to the amplifier circuit board, and use a SPST switch to connect or disconnect the other channel, so each box has its own mono (or 1-channel) selector switch. These Kinivo portable speakers are my favs – ?&tag=431-20&ie=UTF8 can play excellent quality sound.

A well-designed speaker will also have lots of LED lights which blink depending on which of 17 different crossovers are activated (floor to ceiling, remember- you think it’ll just be a 3-way?). Modular Design – headers connect the speaker and battery pack to the circuit board, so you can easily try different configurations or replace a broken part. The small horn speaker kit goes together much like ready-to-assemble furniture. For the money you outlay on this you can for a little more, build a proper Hi Fi set of speakers that will sound excellent.

Speakers and audio systems are great ways to enjoy music and entertainment with your friends and family, but if you’re weary of spending too much on these technological devices, then these DIY activities are offering some creative cost-effective alternatives. Attempting to use Off-The-Shelf parts like this will result in a speaker that sounds like crap. The manufacturer specifications for drivers can only help so much in determining speaker box volume and crossover design for your system. Tom has designed speakers using planar magnetic and Heil Air Motion Transformer drivers for mid and high range units, and very high linear displacement sealed box subs.

Other manufacturers of tube amps & kits include Bottle Head , Decware , Welborne , Wright , and Moth Audio These low-powered tube amps (3-10 watts per channel) are well suited for very high efficiency speakers (97dB+ 1W/1m). The front of the box is just wide enough to fit the mid and tweeter, and the box is just deep enough to fit the woofer on the side. Perfect for crafty individuals who have an affinity for high-tech gadgets, these DIY speaker systems will definitely showcase your passion for customized products. To attach the tolex to the cabinet I’ll just brush some contact cement right on the plywood.

Commercial entries or entities are prohibited: Individuals or entities that sell finished speakers (part time, full time, or any time) are excluded from registration. Similar in concept to the Sonab and Bose speakers of the 70s and 80s these kits are designed to provide a high quality, spacious sound, and are very versatile in their placement options. I’ve also used in the past in order to source cheaper parts (including a speaker). Even though an amp would make my guitar (usually a Tele these days) sound better—and louder, of course—it can be a pain to grab one, plug it in, re-situate myself on the couch, etc. Tom turned his hobby into his profession and began work in the electronics repair field.

His comments were that whilst the frequency extremes aren’t the best ever, if the price of integrating them with other drivers is to lose some of the magic in the sound then it’s not worth it. the weaknesses are easily tolerable because they give so much more information than normal speakers. The speaker of the Samsung Galaxy Note II sits in the bottom left on the backside of the phone.

The simple answer, is that at just under $15 each, we start by buying 8 of them – 4 for each speaker. Whatmore – this is about as simple a DIY project as you can get – i’d enourage you to give it a go! Typical testing equipment involves a microphone plus computer software to analyze the response of your speaker system. The main difference between this schematic, and the one listed in this article, is that you have an extra potentiometer to control the gain (a must have with a guitar amp). If you used the same amp I did, you’ll notice a loud pop when it turns on. This is a side effect of being cheap! You now have very low inductance speaker cables that are equivalent to 10 ga.!!!

EVERY dimension in ANY speaker cabinet design WILL DEFINITELY affect the acoustics either enhancing, detracting, or null, the latter of which is virtually impossible. We’ve featured other unique speaker builds , but this is the first 12-speaker omnidirectional speaker we’ve seen. My box was so thick I needed to cut a little relief inside so the power jack would reach through.

Step Six: Wipe away any dust or debris and give the boxes a few light coats of primer on the inside and outside of the box. You only want sound waves which come from the back of the speaker cone to greet your ears if they have been slowed down (port, transmission line, etc.) or reflected so they don’t cancel out the sound waves coming from the front of the speaker cone. If that’s your leaning, Parts Express is a well-stocked and reliable source for speaker builders and a good place to start.

PVC’s much lower resonant frequency coupled with sand filling as a damping material and now we’re talking about a good sounding speaker stand. Sharing a power source like we just did creates a ground loop that will make your speakers buzz! For the best bass performance, seal any gaps or air leaks in the box with hot glue or caulk then fill the box with a moderate density of Dacron pillow stuffing. It turns out that MDF is not only cheaper, easier to mill and less susceptible to warping and shifting than hardwood, but the difference in densities of the MDF and plywood also reduces cabinet vibrations when you layer them together.

Using David Mellis’ documentation for Fab Speakers , solder together the electrical components using a soldering iron, making sure the speakers will fit into your jar—the 66 mm speakers should fit a small mason jar. No reason to start over and change your box design to decrease the volume of a chamber by a couple of square inches when you can keep the current box and make it stronger in the process.

All ported cabinets, for instance, have a resonant frequency curve which looks like a saddle (preference is always flat hence no coloration of sound) with the valley of the saddle corresponding to the resonant frequency of the speaker cone. What speaker did you use as it probably cant handle to low freq’s well without distortion. I share them here because simply building a speaker is not necessarily an easy task. In the end, I found a speaker stand that was pretty similar looking and everybody seemed happy with it.

Sharp edges on the front of the speaker box will cause distortion, so rounding the edges can make a world of difference. The benefit obviously is that the speaker cone is free to vibrate more faithfully representing the varying voltage it is receiving. Hearing things you’ve never heard on your favourite CDs before through a speaker that you’ve kept in the shed for a decade is a sobering experience! For years, Bedard had friends who were pushing the Klipsch La Scala speakers on him and he understood why. Note that amplification increases when the phone speaker faces the bottom of the bowl. One of the cleanest sounding speaker cabinet designs in the world uses concrete.

Volume: I measured peaks 90dbs at 1 meter distance before distortion set in. This was with an 8 Ohm speaker of mid/high efficiency. Other People’s Projects – Here are a few writeups I did as I built some projects designed by some of the DIY masters out there. All sound waves coming from the back of the speaker cone and reaching the front will cancel out sound waves coming from the front of the cone because they are 180 degrees apart unless those waves coming from the back are slowed down to correct phase cancellation.
