I've built a couple of pairs af speakers, and a few subs, and I am very pleased with them all. However, it did occur to me that it is quite expensive to build a pair of speakers compared to buying a pair of highly rated ones off the shelf. So:

    Do we build speakers to save money?
    Do we build speakers purely for the experience and thrill of building our own stuff?
    Do we build speakers because it would bever occur to us to buy them!

I'm keen to know your views before I embark on my next project.
Thanks,
Mark

I build speakers because the off the shelf ones are crap or a rip off expensive.

@RevM,

Do we build speakers to save money?

Sometimes yes, sometimes no... I'd say that for the same amout of money, you have the possibility to build better and more following your needs or taste.

Do we build speakers purely for the experience and thrill of building our own stuff?

I must confess that it's rather true for me, but not only.

Do we build speakers because it would never occur to us to buy them !

At the price where some speakers are sold, I'm tempted to say yes indeed !

But it's me, OK ? :)

-tbln.

i've been spending my time lately looking a what diy compared to commercial offerings are and in most cases a sensible approach with material choices and design it's far easier to get better performance at the same price point IMHO.

All very interesting, thanks.

It does strike me, though, that commercial designers have access to CAD/CAM and simulations that I don't. They are able to produce really funky designs that they can simulate and test while I am left with an pencil, paper, calculator and a load of formulae! However, I also believe that my speakers sound better than commercial ones at the same price. Seems odd.

I built a set incorperating 1" tweeters and a 5 1/4" midrange. The drivers were Peerless and in a box same size as mine they were selling
for $4,000.00US a par. I payed less than $300 when finished for the wood and drivers. The xovers I left out as I am x-overing in the pre-amp stage and using separate amps for each speaker but the x-over would add about $125 to the total. The sound is wonderful and I venture to say as good as the retail set. So $425 or $4,000 for the same set.

1.) Purely economically, I think you do get better quality in terms of possible construction and raw parts for a DIY project than you get spending the same money on a finished speaker. In my experience, a well designed DIY project will pretty much always beat out comparably priced production models for sound quality when compared dollar to dollar. I try to design DIYs to be at least 3x better in quality per dollar compared to a similar production model.

That said, I think you also have to account for what your time is worth. If you account for the number of hours it takes to design it, build it and any tools you might need, that value may disappear.

2.) I personally love the process of finding raw drivers, designing crossovers, designing boxes and building things in general. The hours it takes to put it all together is very satisfying. Sometimes I even just pick out random drivers online and try to make crossovers for them just because it's fun... with no intention of building a finished piece.

3.) I'm not going to say I'd never buy another pair of speakers. Sometimes that's just the right solution. But I've discovered that I can build them for myself, there's no going back. I'm addicted.

If you want to try some simulation software, you might want to look into one of these free programs. They really allow you to experiment with your crossovers providing instant visual feedback. It almost feels like cheating.

If you ever need to convert a picture of a response graph to .frd or .zma data you can also use this:

Good Luck :thumbsup:
