Hawaii 5.0

[Kofi Annan]

I've heard good things about the Hawaii 5.0 and I have a set of RS 40-1197s that I'd like to do something with as soon as Dave's (Planet 10's) phase plugs arrive.

I can't seem to find the plans for the Hawaii 5.0. Would anyone be kind enough to post them?

Thanks,
Kofi

I lost the plans on another computer but heres the t/s on the 40-1354. It was merely a bottom vented bookshelf design that was apparantly nice but didnt fully take advantage of the drivers LF ability. Bob Brines TWQT/ML designs are a better bet. But if you want a smaller enclosure, plug the t/s into winISD or similar.

Upon re-reading your post, I now realize you have 40-1197s and these were not the drivers used in the Hawaii. I have bipole floorstanders and open baffle speakers with this driver and they are excellent for a frugalphile speaker.

Hmm... thought the 1197s worked in the Hawaii, but it makes sense that they wouldn't since the 1354's are MIA now and the Hawaii 5.0 plans are ditto.

If you've got any ideas for a good design for the 1197s, I'd be glad to hear it. I've only got two 1197 drivers, so the bipole is out of the question.

The Buschorn is a favorite and widely used. A small sealed enclosure used with a sub is nice and my favorite is on a large baffle (dipole) with a helper tweeter above 10K and a dipole W sub.

Thanks for the link!

I've made planty of horns lately and I'm really looking for a small bookshelf deal or mayble a voigt pipe. Any ideas for a bookshelf / voigt pipe (non-dipole) with the 1197s?

How about these? Anyone had any experience with these?

Any other speaker designs would be welcome... and thanks for the input, amt!

As mentioned, the Five-O is for the 40-1354. For interest sake, here is a link:

The Solo103 looks like a nice bookshelf project. Along the lines of a bookshelf you can consider the Fostex BR enclosure for the FE103.

Good luck and let us know how you make out.

Folks seemed to like the folded Voigt pipes loaded with DD's tweaked 40-1197s I slapped together for something to bring to the Atlanta DIY Meet a couple of weeks ago. They were designed around stock board widths to keep cutting to a minimum, with external dims of ~24"h x 10.75"w x 7.25"d.

I imagine the 40-1197 would work in them, but won't have the extension/gain of a long pipe.

GM--

I was at the DIY Atlanta meet and saw your 1197s there. I was very impressed with the sound you got out of them.

If you ever decide to post the design for those, please let me know. I am nothing more than an amateur at this with very little experience, but I have been learning by doing and your speakers would certainly be worth doing.

I understand that posting the plans is easy for me to request and hard for you to do, so if I were going to try and design my own, where would be the best place for me to learn about a basic design?

I know about Speaker Workshop, but I don't think that it does MLTLs. Also, I read somewhere that Martin King removed the MathCad worksheets from his site, but I've just been over there and it looks like they're still available. I'll download those and try my hand.

Any other ideas on these? Jeez, sorry for all the questions!

Thanks! Did we talk? Kofi Annan certainly wasn't there, so who are you?

I don't have any drawings, just some notes, though DD said he would make one (and I assume either post it on his site or sell it for a modest donation to help defray his site costs, his choice), I just haven't gotten around to sending him the info yet.

I tried to sell them cheap + what DD wanted for the drivers to everyone who showed an interest just to get rid of them and not have to ship the drivers back to Canada, but no one was interested. At the end of the Meet though, Woody and I worked a deal and I'm now the proud owner of some RCA Red Seal vinyl albums, so I'm a Happy Camper!

Well, you can build proven designs to hear/measure how they compare to their sims and change them to learn what does what and eventually you will see patterns that will help you calc a good first approximation to fine tune, or you can do it right and learn the basics of speaker driver, T/S, and pipe theory, as well as everything on MJK's site to help understand how to apply it to best effect. Earl Geddes claims his book covers everything you need to know, but is very math intensive AFAIK...........

Since higher math is an indecipherable language to me, I had to learn by doing, though conversations with folks like Marshal Leach, Altec and many other mechanical and fluid dynamics, etc., engineers helped me to better understand the wealth of knowledge I had collected, but didn't always understand their underlying physics.

AFAIK, only MJK's WSs can do them.
