DIY does have a tendency to attract those people who always want something for nothing, because they believe they are being ripped off. This attitude probably extends into every element of these peoples lives.

Without the traditional Hi-Fi market investing in Driver manufacturers the DIY market will be up the creek without a paddle, to put it mildly. For sure no major drive unit manufacturers relies on the specialist DIY market to keep them going!

Linkwitz acknowledges the cost of doing business:
DIY and the Cost of Doing Business
It seems as I have an attitude problem...

But still - DIY for me is to share knowledge of very good products found and share the knowledge for everyone to enjoy and better. The meaning of this in the posts above seems to mean that the posts is more an appetizer of what a wannabe company might produce IF interest is out here - and sell.

But then again - I had no clue of that the loudspeaker thread was a commercial one.

Sorry for the interupt - keep it going.

Especially for you SpinMonster - I'm really sorry that this thread got totally out of boundaries but keep up the good work.

I posted here to pay a comliment to those who have built and shared designs, crossovers, and shared testing. You took on the position somehow that I was bragging about my work (I wasnt) while I was saying thank you to those who shared their work helping my recent work eclipse my prior best. I posted a test on a $18K speaker that mated a 12" woofer with a ring radiator tweeter to show how rediculous the high end market is when you compare it with the results of a budget ZAPH speaker and I'm treated with sarcasm.

I'm not sure what I did to get the attack and I definitely took your posts that way. I'm sure you are really good at what you do (far better than I if you went to school for it). I'm sorry if my post offended you in some way. I wasnt bragging but rather saying thank you to those who helped me.

Sorry, yes very sorry indeed to what seemed to be an attack on you personally. That was not my intent! The answers in the thread gave me all knowledge I need. Sorry again Spinmonster... Keep up the good work and don't give your findings to the dragons! They will absolutely without a blink steal your ideas and sell them as their own - due to small pay in the indusrty (now how ever else could I understand the whinining in the previous posts?).

Now, make sure that everyone understands that this
is your design that everyone acknowledges. This is the crucial point. After this it is quite lost for the dragons - the more you show up on your ideas the better it is - the more popular it gets there may be another industry popping up.
The dragons will then have a few ways to go - bettering their offers or offering better ones.

Now, again if you don't understand what I wrote I can't see it in any other way that you are out fishing to find out what the DIY market would prefer. Now - if that would be the truth - does that make me bad?

Doesn't diyaudio serve as a meeting place for rookies and some of the greats. It amazes me that I have been mixing with Lynn Olson, John Kreskovsky and Jack Caldwell in threads!

So many different approaches to good sound. But these people are deep thinkers, and it is a pleasure to learn from them. It's like speaker university.

They've got me reading Steen Duelund at the moment. He has a way of thinking outside the box, and since I like to share, it all seems to lead to Fourth order Linkwitz-Riley filters and wide bandwidth drivers with smooth slopes.

I do it because I love it. Like the old Greek mathematicians. Hope you do too.

DIY is a force for greater good certainly.
This is a golden age for DIY, global communication between users and expert designers, far better drivers, far more variety, great software, active crossovers, experts sharing with novices, B.S and snake oil is exposed, fantastic!

Also I think DIY can influence commercial design, if not to the same extent as the other way around.

Bring on the exposť, bad designs deserve derision, sort the wheat from the chaff. Remember the Hi-Fi industry is small, the ultra high end vastly smaller, some of these absurd designs with high price tags probably sell in single numbers. Find them in the classified ads some years later and you could well get the actual pair the magazine heard.

Weird and not so wonderful silly price tag designs actually get put into production and reviewed in mag's, but in what numbers? is this proof that the high end is simply pure snake oil? of course not, this is also misrepresentation.

Another thing a lot of us like doing is getting folks to upgrade ropey old speakers. It's not hard.

I once found a pair of nice vented voicecoil 8" bass units new in a junk shop for £30. No idea what they were really. Imagine my glee when I then found a pair of empty stripped Wharfedale Linton cabinets in the street.

Thankyou God, I thought. I bought a two way Maplin crossover and a pair of tweeters and lashed it up with a DIY reflex tube under the bass. I really had NO IDEA what I was doing. But after a few tweaks, those were as good a pair of speakers as I have ever heard!

Hey, who upset SpinMonster? He's edited his opening post. Bad business.

I am amazed how confrontational/sensitive some people get round here. I thought we hung around here for FUN. Anyway, I have a new driver to look at, thanks to SM. Good man.

Shall we continue to share groovy ideas. Here's one I liked. This diagram of mine shows how amplifiers are really all the same. Mosfet, Transistor, Valves.

...All the same. Now tell ME something interesting.
