DIY Waveguide loudspeaker kit
I am finalizing the design of a 10" two way system ala the ESP10 at www.ai-audio.com. This speaker has very high output and a very clean response and sound quality. I am going to sell it as a kit.
Would people prefer to buy as few parts as possible or a completely packaged all-in-one kit?
The crossover design is specific to the drivers, which are B&C, and so using other drivers is risky and likely to be a disaster. But I can get B&C drivers at a good price and can send them directly to the builder. Would people want to buy their own drivers even though I can sell them cheaper than they can buy them? Remember the crossover only works exactly correct for the one specific set of drivers. It's not feasible for me to do more than one crossover design because they take so long to do.
I can get the crossover parts more reasonable than most people can buy them for. Would people still prefer to buy their own parts?
If a full kit were a much better deal than buying the individual parts would people prefer the full kit? Piecing out the sale means I have to charge a lot more for the individual parts.
A set of drawings would be possible, but the waveguide and foam plug are very difficult for the DIT to build. I could just sell the baffle, waveguide and plug and the builder does everything else, but this too requires a lot of competance in doing a good crossover etc. I don't just use a single axial response, my crossovers are optimized for the full polars - which is not trivial.
I'm just trying to get a feel for what people are most interested in.
Thanks for any input you can give.
Most DIYers prefer to construct their own speaker enclosures.
So IMHO, your best chance of success with this new system would be to package all components, including drivers, crossover parts, waveguide, phase plug, input terminals, recommended damping material, etc, and supply a full set of enclosure assembly instructions.
Good luck with your venture.
Does it go to 110dB continuous? That's dangerous.....
I'd be inclined to want just the waveguide, baffle, plug, and schematic/plans. You could offer 2 versions, the proprietary stuff only version (above) and a full on 'kit'. I also strongly suggest issuing a CD along with the kit, including some test/setup signals and extensive build documentation.
Some options would be:
Offer pre-assembled XOs and/or unpopulated boards
Offer flat-pack cabinets
If you'd like, I'd be happy to betatest the kit for you.
I saw you at THE show a few years back, but didn't get to hear the speakers, you were engaged in conversation and I hadn't seen the waveguide tech previously, so didn't have the interest I do now.
Shipping all the wood for the cabinet will be expensive so I'd think you just want the hard-to-get/proprietary stuff in the kit.
I would be interested only in waveguided baffles with plugs, ESP15 especially :)
I think these are the most valuable parts in the kit.
I would most like to be able to buy the waveguide, plug, and plans. Drivers and crossover parts I'd prefer to buy myself, as funds allow.
I would prefer a more complete kit. I don't see any need to buy my own drivers and crossover components since you can provide them at a lower cost and also ensure they meet your specs.
Yes they will easily do 110 dB, without breaking a sweat!:)
Now, there is a limitation that you MUST understand. The waveguides will not be wood and have to be bonded to wood - MDF in this case. So the MINIMUM that I can supply is the full baffle with the waveguide bonded to it. (You could easily cut off the bottom for the waveguide only.) Options to this most basic part are simply not cost effective, especially since this will be the single most expensive part.
I thought of four maybe five levels.
1) Baffle only (non-routered edges) about 33% of total cost
2) Baffle and crossover design and parts about 50% of total cost
3) Baffle, drivers, crossover design and parts, about 80% of total cost
4) Baffle, and drivers, crossover design, about 70% cost
5) Everything (Routered baffle) 100%
(Baffles come with foam plug and driver mounting plate.) The baffle is 1.25 " CLD MDF. Edeg round is 1".
It seems to me that 2 and 3 are not worth doing because you may as well at least get the drivers too. 1), 4) and 5) make sense to me.
A flat pack for the cabinets is what I had in mind - I would never assemble them - that makes no sense. If you consider that $600 was my target price you can see what the options would be.
Earl, I think you're making life difficult for yourself with all the options. Stockholding and order processing could get very complex. I'd go for two options 'till you get yourself up and running, baffle with waveguide and foam, and complete kit, your options 1 and 3. You can always add more choices, depending on how sales go, later down the line. ;)
I sent you an email. Let me know if you get it.
