Greeting once again folks, okay here is the plan, until I can obtain the big machine I will forge ahead with the alternative. Which is to borrow the crossover from another speaker and design and build the cabinet, fully time aligned and mirror imaged. This way all that will have to be done is to construct the new crossover and then compare the two side by side. As fate dictates this model will just so happen to be right in the middle of the two speakers I had originally intended to design and construct, the 4 or 8 way systems. The reason being that the borrowed crossover is a five way system that I have added a 15" sub woofer and sub woofer crossover to making it a six way system, the photo shows all the parts except the 1 " dome tweeter which has not arrived yet. After having examined the borrowed crossover very closely their is no way anyone could know what was going through this guys mind to be able to design and construct such an apparatus as this. The amazing thing is that it actually worked, and there is no speaker at any price today that can compare with the sound and sophistication of this one. The most difficult aspect of this current project will be the location of the crossover, putting it inside the cabinet is impractical because it produces heat which should be vented along with disruptions from magnetic fields and placing it outside posses a risk that it could get damaged for a number of reasons. But I will think of something. This could easily take a couple of months to achieve so until then have a safe day.

Greeting once again, after further study i have learned that you really can't just wind up an inductor and throw it on a $100 meter and get an accurate reading. Its more like do the calculations to make your inductor, wire it up to your circutry, turn it up to full volume, and then test your reading on a $4000 or more machine and if you don't get the numbers back that you were hoping for start over. Well lets say that if you were starting from scratch and wanted to make the big 8 or 10 driver system you could probably spend a life time designing, finding the parts and testing the thing and then you would still have to find the time to actually build the speakers, market and sell them. So we are going to have to take another approach since there is no support from the family on this project and right now I dont have the finances to buy the machine and begin a lab of my own.
Things to be considered are do you want to just try and recreate the sound of the past (which by the way is still over the top of many of today speakers) or try to improve somehow on that same concept while still making them user friendly. And what I mean by user friendly is making them so they can be easiler transported and something that you don't need a mansion to hear properly, again this is no easy task but I believe can still be accomplished. Below are some old speaker inductors I picked up,most of which have no values attached and most of which I have no idea where they came from, but I will toy around with them and build some circutry. Then listen to them and either find a lab that can test the values, or a job in a lab devoted to finishing the project, or find some investors that would prefer to start a lab, or wait until I can save enough money to get the machine needed to read the values. This could take some time or I could get lucky and things might speed up quickly, if you know anyone or are interested yourself in helping to further this project contact me at mvcproducts.com where these speakers will first be offered to the public upon completion, and we can make a deal. Until further notice have a good day.

This is the crossover of the 1970's, the circular objects are the inductors, five of them, the other parts are resistors and capacitors. These are not the only inductors i have seen like this. And the only thing I can think of is that most of them are just copycats of the orignal 1970's version.

Good day folks. This is my favorite month of the decade, but you need not be concerned about that. I was hoping to show you some crossover technology from the 1970's but I seem to have lost that file. Anyway it was a 5 way speaker that had been crossed over at a 6db/oct rate and toned down with a bunch of resistors. The pair sounded fantastic but I now wonder exactly how much they knew and how much was experimental and just sounded right. Because the dimensions of the inductors are completely different from the ones I am about to receive. Which makes me excited about what this 4 way system could sound like. Previously I had showed you a picture of what I thought would be a close version of a tweeter inductor, and the difference it made. Well that difference was at extremely hi volume where one ear was piercing and the other was not, at low volume you really could not tell much of a difference at all. These new inductors could produce off the charts at all volumes. Primarily because the people making inductors today have never done this before, it is new to them and they had to start from scratch, a rather enormous task especially for anyone not really knowing what they are doing, like possibly back in the 1970's or your average joe who is just winding up an inductor on his lath. Your ability to measure the inductance is only as good as your equipment. So we patiently wait for our precious inductors to be delivered knowing they should be far superior to anything in the past.

Hi all, today we have a picture of an unshielded tweeter inductor perhaps 2000 or 3000 Hz, ours is going to be cut off at 5000 Hz. But even this inductor placed in paralell has a dramatic effect on eliminating the harshness of the raw tweeter and does better than a resistor because the inductor acts as a resistor in addition to acting as an inductor. The other photo is an inductor being used in circutry, to complete a 24db/oct it would need 2 capacitors and another inductor and to fine tune it you would need to get the inductances correct and for our purposes wind it to 5000 Hz. I knew these inductors would be a major link in the success of this project and they were the first thing i began to investigate and the only thing i'm still waiting on. Have a good day.

TESTING

Hi folks, well, the pre-amp is back and the equipiment test was positive, power to spare. So with the cd player pluged into the tape input I tested the raw drivers, all eight of them. And with out having been lifted or time aligned or contained or crossedover they sounded pretty good, which tells me that all the equipment is working just fine and the speakers just need to be fine tuned. We are still waiting on the most crucial part, the inductors, which hopefully will be coming along soon. Until then have a blessed day.
