Default Small 2-way Project

Guys-

I'm looking for a little help. I'm interested in making a small 2-way used just for 2 channel listening, I was wondering if anyone has any experience with the following designs.

MurphyBlasters CAOW1
http://murphyblaster.com/content.php?f=CAOW1.html
or
http://www.execulink.com/~kandfbuck/index.htm

Zaph's Audio
http://www.zaphaudio.com/audio-speaker12.html

Troels Gravesen
http://www.troelsgravesen.dk/W15.htm
or
http://www.troelsgravesen.dk/W15_Neo3.htm

They all look great, and before I invest my hard earned cash I like to hear from someone who has built one of these projects.

Thanks

John

Default come over to the dark side...

and experience fullrangers if ya can

seems like all the choices you have made are for what appear to be VERY nice small 2 ways. I can't comment on the sound but all those mentioned have had very good reports, all use good quality components, and all have had revisions (I think) which shows that the designers continue to listen to their loudspeakers and take feedback from those that have built em. Ask the authors for a list of those that may have built em.. I'm sure there are some folks here who have.

That's an excellent idea, I'll contact the designers, to see if they know of anyone who has used their design
I think these are all excellent projects, I was just hoping to get a little feedback from builders in hopes of manking my choice a little easier.
Thanks

John

Hi,

IMO the Zaph design is the most cost effective and balanced.

The DM design is probably best built with all GR drivers, the budget choice.

The W15 designs with / without ribbons are all expensive.

I have done Zaphs L15 project, and it's fantastic. My only changes were both speakers are centered, and the Lpad resistor in mind was 1.5Ohms. It's a great design, with fantastic imaging, and a little thump to boot due to the long throw design and superior basket on the woofers.

it doesnt look like you can really go wrong with any of those designs, all i can say is that zaphs knowledge is seemingly infinate, and all his deisgns take pretty much everything into consideration.


....nanook a no-no, nanook a no-no! dont be a naughty eskimooowhoaaaa

Default I'm a dancing fool..

.,as well:
"some people prefer cupcakes,
while I prefer muffins...
I am a muffin man" :-)

Like I suggested, any of the speakers you mention are or have been evolved and seem to have great followings. Zaph, Planet10 (come over to the dark side, don't need no stinkin tweeters), GM, simply too many to list.

wish I was where you are when I started out....

Thanks for everyones advice and opinions. I've order the parts for Zaph's L15 speakers, from Madisound and I'm looking forward to putting these things together. I'll throw some pics up on the web site as soon as things start progressong.

Thanks

Good choice, you can't go wrong with it. My musical taste ranges from 80's rock and even metal, to jazz fusion, blues, jazz, Pop, and Classical....and I truly believe they all sound good on these. Keep in mind, for rock and metal (if that's what you like) you may want to go with a bigger design like the L18 that Krutke did. You just need to be careful with the 4ohm impedance, though I doubt that's a real problem for any modern solid state amp...

Good luck with it!

One last question, I purchased the Seas 27TFFC tweeter and the components for the optional high pass response shaping circuit, should I have just purchase the Seas 27 TDFC and skipped the optional filter. I ask because I need to order some more parts from Madisound, cost is not concern. Also how important are the resistance values on the inductors??? Should I try to mach them exactly or is a lower resistance number acceptable. Thanks again I appreciate everyone’s help.

John
