Stereo west was well know inphase out in west omaha. Loud and clear was right around the corner. which now inphase currently resides. metro audio dynamics moved a few times. A couple of other orion dealers in town that i can not recall the names off. I remember all those competitions every year all the battles between the stereo shops. I looked forward seeing the creative installs. The sq/spl judging for top trophies. Back in the day everyone appreciated the hard work and dedication to their builds and helping others sound their best. I miss all those days not like today. History is in the magazines glad i own a few year. It would have been a pleasure I am sure if I heard and seen your hard work and dedication to the sport! Keep car audio memories alive Thanks for sharing your experiences!

Understand that the path length under the seat is very long. Much longer than that from any other place in the car. While this is ideal, it also means that that matching to other speakers which have much shorter path lengths is paramount. <br />Here are the steps to a trick I used many times with absolute success: <br /><br />- Focus only on the sound quality at the crossover frequency between the two speakers that are being matched. <br /><br />- Listen to the height at that frequency. The height should be at anyone of three places: <br /> (a) above the dash, <br /> (b) right in the middle of the dash (air vents, radio, etc)<br /> (c) or near the floor.<br /><br />- If the sound is (a) above the dash, you have chosen the right crossover and the right frequency. From (a), changing the crossover slope by 6dB's is not advisable. From (a), changing the crossover slope by 12dB's could be accomplished if you flip the polarity of one of either the low pass or the high pass speaker but not both. From (a), changing the crossover slope by 18dB's is not advisable. From (a), changing the crossover slope by 24dB's could be accomplished if you retain the polarity of both speakers. <br /><br />- If the sound is (b) right in the middle of the dash, your setting is wrong. It must be changed. From (b), testing the crossover slope by changing it by 6dB's is highly suggested. From (b), testing the crossover slope by changing it by 12dB's is not advisable. From (b), testing the crossover slope by changing it by 18dB's is highly suggested. From (b), testing the crossover slope by changing it by 24dB's is not advisable. The goal from all these tests is to get to (a) above the dash.<br /><br />- If the sound is (c) near the floor, you are in luck. Simply flip the polarity of one of either the low pass or the high pass speaker but not both. This should get you to (a) above the dash. <br /><br />If successful on getting the sound to be above the dash, then go back to (a) and try fine-tuning. If not successful, keep experimenting with the frequency and or crossover slope.<br />By the way, I am including what to expect when changing slopes so that you may find one or two settings that work OK. In this way you will be able to select the best of them. It's all about playing. <br />Changing by 6dB's means that if you're starting from a 12dB/Oct slope, you would go up to 18dB/Oct (12+6=18) or down to 6dB/Oct (12-6=6).<br />This method can be used between any pair of speakers but is essential when using speakers of very different path lengths.<br />When done right, the resulting sound will be big and transparent. On the other hand, when crossovers are poorly done, expect musicians to seem like midgets. While IASCA judges seem to like the little-instrument type of distortion, diminutive images are a character that is completely missing in the real world. Just stay quiet for a minute and listen to your family around the house. They will certainly not sound vertically constrained. Why, then, should your hi-fi be small sounding?<br />Enjoy playing with your system and feel free to share images. If you chose to share, just send me your email on a comment that I will not make it public. Instead I will just use it so that I may send you mine. You will then be able to send images directly to me. I will be more than glad to add any text you may want to share as well. My goal would be to share seemingly crazy ideas. albertoalopezhttps://www.blogger.com/profile/01993782226348320330noreply@blogger.comtag:blogger.com,1999:blog-5773772622008994113.post-13736744844170263002016-05-12T22:37:24.713-04:002016-05-12T22:37:24.713-04:00as soon as i read this i went out to my car and te...as soon as i read this i went out to my car and tested the posistioning and saw some amazing results. got me thinking up a few interesting ideasAnonymoushttps://www.blogger.com/profile/14797007185147663990noreply@blogger.comtag:blogger.com,1999:blog-5773772622008994113.post-7184990102839080912016-05-12T19:27:39.852-04:002016-05-12T19:27:39.852-04:00Steven,
Physics are constant for both a truck and ...Steven,<br />Physics are constant for both a truck and car. Understandably, the only thing that changes is the ease with which a speaker could be placed underneath a factory seat. Trucks have seats that are placed further above the floor than those from cars. This extra clearance makes it easier to insert the waveguide and it's motor under a truck's seat. For tighter applications a waveguide such as those sold by Illusion, which place the motor at the back of the guide rather than above or below it, may be a better choice. But again, the issue is mainly the space. <br />Over time, Matt Billmeier's truck would have benefited from completely re-fabricating the structure under the seats. Making this change would have allowed the guides to be placed further to the outside of the vehicle. While requiring a much more advanced set of installation skills, this would increase stage width by a substantial amount.<br />The same could be done in a car but it would require the help of someone who can make very precise steal brackets. Let's remember that s car seat is exposed to tremendous forces during even normal driving conditions.<br />At the end of the day, floor carpeting and seat cushions provide a few extra inches of space that is never immediately available when looking at an install. At least this is my experience. I was always able to squeeze things into spaces that seemed too small for the application. It was all bout extracting millimeters of extra space everywhere possible. <br />If you try placing the guides under your car's seat, consider matching them with a very fast midbass driver positioned in the floor as well. A solid enclosure would be essential to prevent the type of enclosure resonances that call attention to the floor. Recently, I guided a competitor with his speaker placement and his installer built a supposedly rigid enclosure. Well, maybe it was rigid for car guys but certainly not for home specs. The box had to be remade three times. Each time it came out better. Still, rigidity didn't happen until real fiberglass and braces were applied. For car guys, a brace is a piece of wood. For me, braces are a set membranes that follow a randomized pattern designed to redistribute energy according to pressure and speed. <br />Finally, MDF may be ok for some uses, but for very good results, it must be covered front and back with real fiberglass. It seems that car installers think that fiberglass results when using resin over fleece. They seem to somehow miss that there is no "glass" in that stuff. No, use real fiberglass or carbon fiber instead and apply it to the front and the back of the MDF. In this way a constraint-layer composite will be created of extreme rigidity and tremendous ability to opposed resonances. Maybe this could be a good subject for a future article. <br />Thanks for your inquiry. I too get excited about this stuff.albertoalopezhttps://www.blogger.com/profile/01993782226348320330noreply@blogger.comtag:blogger.com,1999:blog-5773772622008994113.post-17526308621558655442016-05-12T14:56:33.200-04:002016-05-12T14:56:33.200-04:00SO THAT SAID, DO YOU THINK IT'S POSSIBLE TO GE...SO THAT SAID, DO YOU THINK IT'S POSSIBLE TO GET HORNS TO WORK IN A REGULAR CAR IF FIRED STRAIGHT AHEAD AT THE FIREWALL?<br /> not yelling, just inspired. steven hubbsnoreply@blogger.comtag:blogger.com,1999:blog-5773772622008994113.post-30120798636620208452016-04-07T00:06:07.898-04:002016-04-07T00:06:07.898-04:00i know the legendary speakerworks cars well. as yo...i know the legendary speakerworks cars well. as you di, i studied them voraciouslyAnonymoushttps://www.blogger.com/profile/14797007185147663990noreply@blogger.comtag:blogger.com,1999:blog-5773772622008994113.post-81630586236663412842016-04-01T10:28:10.136-04:002016-04-01T10:28:10.136-04:00Here is the link to the Holdaways page

Now that placing the midbass at the quar...Part Two:<br />Now that placing the midbass at the quarter panels proved to have three main problems. First, there is a big headphone effect. When listening to headphones, it is impossible to project a stage in front of the listener. So while the kick panels were trying to create the stage, the midbass kept pulling it back in a weird way. <br />Second, the experiment proved once again the importance of path length equalization. The two lengths were quite different. This meant that there was a very strong near-side bias quality to it. While I was trying to make center images stronger, the soloists body kept moving towards the outside of the car. I later tested them as woofers and still found the discrepancy in path length to deteriorate bass quality. In a nutshell, you just can't have speakers where one side is so close to your ears. From that point on, I only tried mega long path lengths. <br />Finally, Most woofers have some cone created color. Something about moving large masses at very high speeds means that if you have such a speaker close to your ears, you will inevitably hear the color as a distortion; albeit a faint one. After that, I went on to search midbass drivers of exceptional speed and stayed away from slow speakers like Boston Acoustics and ADS. <br />In the end, I became disappointed. The Peerless sat inside the car for a few years but never again played any music. I only took them out before selling the car after I moved to England. I still have the woofers. They are pretty good bass drivers. Because of their size, they could not be used for the deepest of bass. But they could do very well in a nice project. <br />On the other hand, the idea of placing midbass at the rear quarter panels died soon after birth. Even the Holdaway cars and their systems faded into history. Thankfully, the experience made me place midbass in the floor of my car. There, path lengths were symmetrical and cancellation moved way higher in frequency. My car would move on to having much more imaging and a very sweet, robust sound. By my standards of today, the car would be a very good car at best. But for back then, it was the beginning of a long relationship with stupendous sound; car or home.albertoalopezhttps://www.blogger.com/profile/01993782226348320330noreply@blogger.comtag:blogger.com,1999:blog-5773772622008994113.post-90576713777439745702016-04-01T10:13:15.707-04:002016-04-01T10:13:15.707-04:00In hind sight, it was a bad idea. But I need to re...In hind sight, it was a bad idea. But I need to remind myself that there was a time when much of the art was a mystery and the science was well beyond my understanding. <br />I remember reading about the Holdaway cars; the Grand National that was bought by Richard Clark , and the Acura Legend owned by Harry Kimura. Speaker Works were ahead of their time. They launched waveguides, aperiodics and kick panels into the car audio scene; all which went on to become technology icons over time. Well, both of these cars used midbass placed in enclosures on the rear quarter panels. They were also winning everything in their respective class. <br />The idea seemed to make sense at the time. I had already discovered that midbass in the doors would always cancel based on vehicle dimensions. Trucks, cars or vans were all destined to have a dip centered at about 400Hz. This explains why car audio systems lack 'body' when compared to the simplest of home systems even today. No amount of equalization or amplification would solve this issue. I had to find a solution. In my case, I knew I could keep the door speakers as woofers. But the midbass frequencies needed to be solved. <br />Placing one speaker near my outside ear and the other further away from my inside ear would move the cancellation out of the midbass band. You double the difference between the distance of the two drivers to your ears and that will be the cancelling wavelength. In paper, it was worth testing. Today, we would just use a computer to model it. Then, I did everything by ear, even my crossovers' part selection. <br />A potentially good aspect of using the quarter panels that other places in the cabin would not easily allow was the deployment of a solid enclosure. I always admired how much body small monitor speakers projected because of their use of a real enclosure. While many installers would claim to use enclosures for mids or midbass, most of them were leaky at best. Over the years, many of the best cars in the US found their way to my shop for the purpose of solving acoustic or noise problems. So I am qualified to say that their so called enclosures were shameful attempts, but no more. albertoalopezhttps://www.blogger.com/profile/01993782226348320330noreply@blogger.com
