This web-page is under-development with anticipated completion near the end of calendar year 2021. If that seems slow, this web-page is a secondary and part-time endeavor for me and I am not a web-page designer so I’m learning the web-development aspect as I go. In the meantime, I am offering assembly services using the email on the contact page as the preferred contact method. Thank you for looking

FUTURE SERVICES

AMPLIFIER BUILDS

At a future time, I plan to offer assembly services for DIY amplifier kits. I will likely pre-assemble small batches of popular and proven designs. Examples could include popular ICEpower modules such as the 200asc/200ac, or modules from the Hypex nCore series. Component prices for those kits could range between $200 and $600 depending upon the modules selected, plus an assembly fee.

In anticipation of the question, I have no plans to build or offer any of the lower end, sub $100 kits, as I don’t find them to offer significant value or advantages over the many imported amplifiers already offered in that same price range.

CNC CUT FRONT BAFFLES AND FLAT PACKS

At a future time, I plan to offer CNC services primarily for front baffles, with some selective offerings of flat-packs. Those services would be offered for published cabinet designs or to any custom specifications desired.


SERVICES I DO NOT PROVIDE

I do not provide crossover design services.  

There are many talented speaker designers who already offer this service. I am not trying to compete in that market.

I will not violate intellectual property rights of original designers.

I will not build you a DIY kit crossover that you have not purchased or is not publicly available.  Occasionally, someone has asked me to build them a crossover for one of the popular retail DIY kits, that they have not purchased.  I can only offer assembly services for a kit you have purchased, or for a crossover schematic you have provided.  I will not provide schematics for a build of someone else’s design without their permission, or unless they have made that design public. 


RECOMMENDATIONS

There are many benefits to building a speaker from a DIY kit.

Cost Savings / Value: DIY kits typically have incredibly low mark-up. They are typically sold by their designer or a few select retailers, without distributors, wholesalers, or other middlemen who all add a price increase as they pass it along. There’s no national branding or marketing campaign expenses. You are paying cost for the actual components, with a small and well earned markup to the designer, plus your raw materials and labor for the speaker cabinet.

Premium Components: Most of you reading this, have likely already researched various DIY kits. In comparison, you have seen the insides of retail speakers and have seen examples of the dirt-cheap tiny crossovers, seen the raw woofers out of box, and seen how crude the interior cabinet construction is, despite an often attractive outward appearance. It is amazing how little product cost goes into a retail speaker. $15 worth of crossover components, $40 worth of woofer and tweeter, thin walled and un-braced speaker cabinets, and a $250 price tag. Don’t misunderstand me, some of them can be very enjoyable, may be very well rated, may sound very good even. I own and have owned many retail speakers that I have been pleased with. However, side by side, using objective measurements and/or subjective comparison, they generally don’t perform as well as a professionally designed DIY speaker kit of similar but lower price. This is the reason why once people go down the path of DIY speakers, they typically never go back to retail.

What kit to build?

There are so many great options. This website is still under development but I will add resources and kit reviews in the future to further assist you towards a great DIY kit or build plan if you haven’t already selected one. In the meantime, my basic recommendations are as follows:

Spend a little more– At the bottom pricing ranges, small cost increases typically do provide very immediate and very noticeable improvements. What that means is: Yes, the $300 pair of speakers will perform better than the the $200 pair. The $200 pair will be better than the $100 pair, particularly if both options have similar design principles, and similar cost mark-ups; Of course there are always some exceptions, and some well renowned designs will perform above their price bracket, even compared against other DIY. However, that general rule applies when comparing reputable kits from reputable designers. The increased cost goes directly into improved components, and generally provides a corresponding benefit, when properly engineered. The $200 increase from a $600 kit to an $800 kit may be more subjective, but a $150 increase from a $100 to $250 kit will bring immediate improvement.

Reputation and experience matter– Choose a kit from named and reputable designers. If you’ve followed any of the many forums dedicated to speaker DIY, the question always presents itself where someone wants to design their own kit, perhaps using software simulation, or is looking for help to design a crossover for their chosen budget woofer. Don’t even think about going this route, unless your goal is to learn a lot through trial and error. Learn you will, but you will not randomly luck into a design that rivals other proven designs. You simply can’t reasonably expect to end up with a quality similar to what you would get using a proven design. Software simulation is not enough and can only provide a starting point. Successful design requires lots of trial and error, adaptation, and more trial and error, usually prefaced with lots of experience and education, and aided by appropriate testing hardware and knowledge. More simply put, if your goal is to build the best speaker kit you can for your budget than don’t try to go it alone. Don’t try to replicate any of the one-time builds that you saw someone post on Reddit, Etsy, Facebook, or a Forum. Anyone can post to the web and share their custom build. They may even provide really clear instructions to follow. However, if they aren’t an experienced designer, than I’m confident they didn’t casually stumble onto an award winning design. Please save yourself that learning curve, and pick a design from a reputable designer.
