Vidsonix 500-watt powered speakers

Integral pole mount socket and threaded mounting points. Comes with two "brackets" to adapt the speaker for floor monitor wedge use, very nice. They performed well, they had a nice crossover, everything seemed good. However the horn failed on one one day, I wrote the company and requested a replacement diaphragm under the warranty which was shipped promptly no questions asked. When I cracked the case open I found that one of the 12v bulbs on the crossover which is used for HF protection was improperly soldered and caused the HF horn to stop working, but when this was corrected with a bit of solder the speaker worked fine. The other speaker also failed in this manner about a month later which leads me to believe this was a widespread factory defect.

L ine arrays offer a method to achieve high efficiency in a relatively small package. However, conventional line arrays also have a very narrow dispersion angle on their long axis. The CurveArray Photo 1 is intended for horizontal placement, offering the high sensitivity of a line array with the dispersion of a point source.

The difference in dispersion compared to a flat array is dramatic. Specs—fs Hz, Qts. Be sure that you choose full-range drivers, with response to at least 8kHz. These tweeters have no mounting flanges, so they must be glued in place. There are many variations of this Onkyo tweeter available, some with coaxial mounting frames that can be discarded. The reason is shown in Fig. Minimizing dis- www.

The usual method of doing so is to space drivers with their acoustic centers no more than a wavelength apart.

The center cabinet is an array that incorporates an outward splay angle. The cabinet on the right shows what happens when the drivers are splayed inward, cross firing. I tested the CA configuration with tweeter spacing half that of the final version, using two tweeters per woofer, and found no improvement below 12kHz. For that matter, you can make life much simpler by not using tweeters at all. Figure 3 shows the response of the prototype without them, and the HF response is adequate for most center-channel program material.

Draw intersects on these lines as shown in Fig. These are the centers for the holes for the woofers and tweeters, respectively. Drill holes for the drivers, sized for your drivers and their mounting schemes. After drilling the driver holes, draw cutting lines on the baffle per Fig. Be sure the angles are facing the correct direction, and that the two end segments www. Sand the baffle segments in preparation for finishing before assembling them, because it is difficult to do so after.

Dampen one mating surface with water, apply a few thin beads of glue to the other mating surface, then hold the two parts together for three minutes. You can tell the glue has set when it foams out of the joint while curing Photo 3. In this fashion you can glue the six baffle segments together in about 20 minutes, which is probably less time than it would take to fashion a jig.

When the glue has fully cured, scrape off the excess with a utility knife and sand the assembly in preparation for applying a finish, taking care not to break any joints. Measure the finished baffle Photo 4 end to end. Cut the back the same width as the baffle. You can go even deeper; for example, if you want to use the cab as a TV stand.

You also can go wider, adding wings to either side of the baffle, should you wish to match the width of the cab to your TV. Should you decide to make your top and bottom from solid wood, the easiest way to joint them is with biscuits, clamping them with clamps and cauls to hold them flat Photo 5. The outboard woofer magnets will come close to the sides Photo 6 , and with some woofers the magnet could actually hit the sides, so trial-fit the baffle, sides, and a woofer before assembling the cabinet, routing recesses in the sides if required.

Glue the baffle assembly to the cabinet top, with the woofer holes being closer to it. If you have enough clamps, you may glue the baffle, sides, and back to each other and to the top simultaneously Photo 7. Leave an equal amount hanging over the top at either end.

If you have only a few clamps, glue the baffle in place first, adding the sides and back after the glue has set. After the glue has cured, screw the bottom in place temporarily. Remove the bottom, finesand as required, and apply a finish. My preference is tung oil, which does a professional job with the least amount of effort. For an airtight seal, use a driver sealing gasket tape, such as Parts Express With a frameless tweeter such as the Onkyo, glue it in place with a hot melt glue gun, first with a thin bead around the frame perimeter, then thoroughly filling the joint to ensure an airtight seal.

I wired those of the prototype in banks of three, each bank parallel wired, the two banks in series. I crossed them over second order at 6kHz, using component values from the calculator contained in my WinISD software www. Install binding posts or a jack through the back, and function-test the cab before loosely filling it with poly batting. Screw the bottom in place, using the driver gasket tape on the joint for an airtight fit.

M any audiophiles are interested in making changes to their audio equipment to improve performance. Tweaks usually seem to be controversial, often without generally accepted explanations—and sometimes no explanations at all—about how they could work. Like many, I trust engineering concepts. Who knows, maybe there are nonobvious or yet-to-beexplained mechanisms operating? I have a special mat placed under my power amp, and a painted statue sitting on its chassis, and I have not the least doubt that they greatly improve the listenability of my system.

The amp is an older, rebuilt, modified Hafler DH I keep it sitting on the floor near a corner, driving my main speakers. I recently noticed a weak but bothersome hum coming from the amplifier.

Apparently, the laminated core of the power transformer was vibrating with the AC power waveform, and the vibration was getting into the chassis and from there to the floor, projecting a low humming sound into the room. I also came up empty after a brief search for an inexpensive replacement transformer. So, I tried putting some folded foam padding under the amplifier to isolate it from the floor. That helped, but the chassis still was radiating hum directly through the air into the room.

I noticed that if I pressed down a little on the chassis, the hum level would drop. Well, soon Nipper was standing guard on top of the power amplifier—and the hum problem is now gone. There are plenty of real, known issues to pursue in audio that have a tremendously higher likelihood—at least for technically educated people—of bearing fruit.

Before I become interested in investing time or money and actually trying some tweak or seemingly unlikely mod, I like to see some reasonable, competent, nonsense-free theoretical explanation about how it might work; or, failing that, some evidence that it actually does.

We regularly strive to be deceived by our systems and to give in to our imaginations. Actual evidence can be hard to come by, though. ABX testing, which aims to offer it, is time consuming to do, and it is complicated to maintain controls that might guarantee a verifiable result.

And ABX also seems like a tedious operation that would not be much fun, at least not compared to relaxing and just listening to music. And the results of ABX are too often challenged on the basis that the ABX switchbox itself might be masking differences that could really be there. That argument seems to me to be more than a little like a dodge, but it could be possible, I guess. And, should no evidence of an audible difference be uncovered in an ABX test, the strongest statement that might be made is that no audible differences were revealed while using that given set of associated equipment, by that particular set of listeners, with those particular recordings, at that particular time.

At best, it might be suggested, but never be proven, that something is completely inaudible. But the opposite could be proven were it to be the case—that something is audible under some circumstances. That would be a useful result and might lead to something interesting. Yet none of these persons have ever demonstrated at an AES convention, for example, the ability of even one listener to differentiate, by hearing alone, when different components are changed.

It seems this would be an easy demo to set up for such obvious improvements, and could result in fame for that listener and a chance to shake up the foundations of audio engineering, while providing excellent press coverage and powerful material for advertisement copy for manufacturers. Cable companies might choose to consider doing this if they really believe in their products. With the lack of interest in conducting time-consuming verifiable ABX tests, or for making clear and incontestable public demonstrations of differences being heard, it would be good to have some other ways to get evidence that tweaks or mods might be worth checking out.

So a good first step toward giving evidence for a tweak or mod might be to show that it does something to an electrical signal in equipment or to sound in the air. You need a way to show when audio signals have changed; that is, when one audio signal made one way with- Your one-stop-supply A S Authenticaps K J A High Grade precision Caps N F I R S And even much more: We stock more than different types of tubes, sockets, books, cables, T resistors, spareparts, transformers, chokes Transformer service: custom made designs, large.

Direct replacement, also for compact amps. Custom designs and dealer pricing upon request. Due to a special fabrication technology our platinum quality High Grade film caps are almost free of parasitic inductance and offer brilliant sound experience in guitar-, audio-, crossover and all other uses.

Rated V DC they are also excellent for repairs. Available types range from 0. It would be better still if you could listen only to the part of the signal that was different, removing the unchanged part of the signal, so you could tell whether those changes all by themselves might register to your ears.

When you talk about differences in audio signals, the concept is very similar. You can also subtract the signals representing sound in a sound system. In analog electronics, subtraction is done by inverting the polarity of the second signal and then mixing summing the two together. If the signals were exactly the same, they would cancel each other out and leave a silent signal, a difference of zero Fig.

If they leave something other than noise, then the signals must have been different in some way. You can use this process to see whether two signals are different, testing whether use of a tweak or mod has changed anything. If you obtain from that a result that seems significant, you will have some evidence. The test could have been done erroneously, for instance.

This is what fits the budget for now. I've been googling around in the last few days, but I couldn't find a definite answer to my question. During pre-purchase research, I've read that both my new speakers and amp are capable of bi-amping. I figured some speaker wire and banana plugs won't break the bank, so there's no reason not to do it if it would improve the sound even a little. My only concern is that the speakers rated for Watt, the amp pumps out 95 Watt.
