GR Research is a fairly small corporation and I spend my time among various aspects of the business. I do some design work, some assembly work, pack and fill orders, handle calls and e-mails, and all kinds of other things.
As I reflect upon my work and think about what it is that I really enjoy most (besides listening to music) it really comes back to the design work. I really enjoy the crossover design work and trying to take things to new levels. I strive on challenges. And trying to get the most out of a given design is very rewarding.
So for the
month of June rest of the summer I am going to offer free crossover design services.
Here are the specifics.
You have to send me the speaker. You don't need to send me the pair unless I am also building them out. I need just one of them. No you can't just tell me what drivers you have and expect me to design something based on T/S parameters. I need them here in the box that you are using them in or that they were designed for. This can include various commercial designs that have fallen short of the mark. I design based on acoustic output of the drivers and the cabinet design (surface reflections) are part of the output. So I have to have a speaker here.
When I design a crossover for you then you have the rights to use it for your own enjoyment and not for commercial profit. If you are seeking design work for something that you intend to produce and sell that I am still glad to help you, but profiting on my design work (my intellectual property) will require an agreement prior to the work being done.
You will get a full set of measurements with the design showing you exactly how it performs.
You will buy your crossover parts from GR Research. I am not going to do the design work for free then hand you a schematic so you can source the parts elsewhere. Budget parts will be recommend for budget designs and higher end parts will be recommended for higher end designs. Options of types and prices of parts will be made available.
You must wire the drivers used in the design so that they can be driven externally. That means each driver has a pair of wires that are accessible even if you have to hang the wires out the port.
There may be a handling fee if you send me a large speaker for me to have to box and un-box.
And you pay shipping both ways.
I can then provide you with the parts and a schematic so you can assemble them yourself, or I can provide assembled crossovers for you. I can even fully assemble the speakers for you. But only the design work is free.
No other company has ever offered a service like this before. Now is your chance to get professional designs services at no cost. You can even send me what you my have designed or had designed elsewhere for measuring, testing, and evaluation. We have always offered free testing and measuring services. Again commercially purchased models are also welcome.
I had so much fun with the design work that I took in for the month of June that I am going to extend the offer for the rest of the summer.
