input requested on new DIY speaker gallery

[paulspencer]

I'd like to create an online DIY speaker resource for those who would like to build speakers without designing the crossover, which is often the biggest impediment. Often beginners are recommended to buy a kit, copy a kit (if the crossover design is freely available), or copy a good DIY design where the crossover is published. Quite often the latter is not available with the drivers that you may wish to use, or it may be that the project exists but you just haven't found it amongst the thousands of DIY audio sites.

Contributions are invited which include:

- your own speakers which you have built - including at least one image, a description and the crossover schematic (if there is sufficient interest, I will create a standard format for people to follow and post it on my site)

- liinks to DIY speakers and kits on the web which have freely available crossover schematics included

Looking forward to hearing about your DIY speaker designs,

Regards,
Paul Spencer

Hello Paul,

I think the idea is a good one. The trouble that normally occurs is in maintaining the links over time.

My first speaker was built following the Audax KLS9 design, but they have since changed their site and it is no longer available. There are however, copies of the project around the web containing the panel sizes, crossover components (very simple first order deisgn) and some alignment data e.g. http://design3d.host.sk/Hi-Fi/Audax/kls9.htm There appears to be some form of kit from http://www.worldaudiodesign.co.uk and at least one member of this forum has built a unit.

Mine would not be a good example to use. For some unknown reason, when I copied the design down, I copied AP210Z0 for the driver instead of the HM model, therefore my cabinet is hugely oversized. I will attack it at some point but....

Is this the sort of thing you have in mind?

Basically I'm looking for anything that can be copied, that is worth copying, and can ethically be copied. If someone were to post the crossover of a commercial speaker, and the drivers used, this would obviously fail the ethics test! To be helpful, the drivers would need to still be available. And to be worth copying, it would need drivers of reasonable quality and a crossover that has been designed properly - you may not be able to really determine this, but I think most discerning DIYers can make some sort of judgement.

Are the drivers for that example currently available?
Yes, I know what you mean about links.

regards,
Paul

Paul,

I hadn't checked on the availability of the drivers, it appears as though the HM210Z0 is no longer made, so this is not practical. On the other front though, the design was from a DIY page at Audax, intended to be copied and produced by individuals, so it probably passes the ethics test (albeit irrelevant now).

I was trying to follow on from the discussion about beginner reference speakers, but I am sure that there are some other cheapish ones around.

I will have another look,
Andrew

Andrew,

Thanks for trying

Look forward to whatever else you might find.

C'mon DIYers, let's hear about those speakers that haven't been posted on the net yet!!!
