What building my own speakers has taught me...


Hi Everyone,

After 8 years or so I have finally finished my "reference" speaker system.  I say eight years because what started as a small, high end 2-way has morphed into a 3-way active system.  Really happy with the results for myself... but I wanted to step back a little and reflect on the audio industry right now. 

First, I’m not here to convince you to DIY your next pair unless you NEED to build something.  And I’m not here to rail against the high price of gear, which does have some merit.   Mostly what I think about is how difficult it really is to make a business selling audio gear, and that I’m actually SHOCKED at how many companies attempt to do so, and even more when they thrive. 

Pricing out all the components in my speakers I come to a total parts cost.  Lets say it’s $1,000.  It could be $10, the actual amount doesn’t matter, but pretend it’s $1k. If I try to imagine "How would I take this product to market?"  I simply can’t get to a selling price under 15 to 20 times manufacturing cost. 

At the same time, the cost of the average "reference" speaker over the last 20 years has really skyrocketed, while the audio enthusiast market has dwindled.   Then along came HDMI whose ridiculous licensing and technical requirements seems to at least have been partially responsible for Meridian and Theta Digital dwindling from the market. 

I can’t imagine how hard it is for anyone besides say Sony or Harman or Samsung to be in the market for audio gear.  Increased costs, high competition, dwindling consumers.....  are we in a bubble or does every generation think "this is it, this is the end of high end audio?"

Please note that this design was not originally going to be a 3-way.  If I were to do this again, I would have made the upper section sealed to start with, which would make it significantly smaller, but I’d keep all the drivers as-is. 

The 6.5" mid-woofer is crossed to the tweeter around 1,800 Hz so despite the large "midrange" I’m using the off axis measurements are essentially perfect. 

Well, I say I'd keep them the same, but the tweeter is about 80% more expensive than when I bought it, while the 6.5" and woofers all cost around $200 each.  I think what I'd do if having to build today is use a Scan Speak air-circ dome instead, like I did in my center. or  as Troels sometimes suggests, the excellent Discovery series tweeter instead. 

I do like scanspeak I think there from Denmark and the amt mundorf.nice job an enjoy the music

Absolutely beautiful and I bet they sound as good as they look.  Very ambitious endeavor.   BTW in case my thanks didn't get your way I appreciate the reinforcement for the Mogami XLR's. --John

After 8 years or so…

I’m too old to start DYI from scratch to reach such a high sonic level.  
@erik_squires - congratulations on your accomplishment
