Anyone completed a Zaph 2.5 waveguide?

neutron7 · 20th December 2006, 01:47 AM

If so, how do you like them, and how much power do they need. I was looking at using them with a 60 watt SS amplifier.

I have a friend with access to a furniture factory CNC router. and we are routing corian baffles and lathing the waveguides (maybe also from corian)

apart from that they will be built to Zaphs measurements and crossover

I haven't ever built something quite so expensive on some guy on the internet's sayso

Hi Neutron,

I have not build the 2.5 waveguide Zaph speakers but I have built a set of Zaph L18's. I can tell you the L18's are great speakers. I enjoy them a lot and would compare them to speakers costing a whole lot more.

I can't think of anyone else that I would trust as much as John for a speaker design. He is thorough and designs his speakers using facts, testing and not opinion. So, I'd go for it and it would be great to see some pictures once you're done. That equipment you have available would likely be every speaker builder's dream.

Regards and best of luck,

I know that John's designs are very well regarded, and from reading his posts on different message boards, he firmly believes in not posting something until he feels it's high fidelity quality at a minimum. That being said, if you like the wave guide speakers, and you can build them to his spec's (baffle size, and internal dimensions) I am sure you will be blown away.

as for the build, how does corian compare? I have some solid surface stuff in my kitchen and bath, and I am curious to know how that stuff would react as baffles? Would it vibrate at all? my solid surface bathroom sink isn't very solid (not like a 1 1/2" piece of MDF would be anyway)

I would think corian would be ideal. At least compared to the flimsier plastic used for the mcm waveguides.

Thanks for encouragement about Zaph speakers!

if you look underneath your sink you will probably find it is not 1/12 inch thick ut 1/2 with a surround to make it look fatter.

Corian has double the density of MDF 100 lbs/cu ft. vs 50 lbs/cu ft. solid corian is not flimsy. its almost like rock.

I have ordered a riser for my Taig lathe so i can turn the corian waveguides. the nice thing is there will be no screws showing on the baffle at all except the speaker bolts. also the waveguides will attach to the baffles and the tweeter very simply without any extra bits needed.

the furniture place could not machine the waveguide bacause you would need a custom (and huge---expensive) carbide router bit made.

the only thing now is to decide what colors to use for the corian and veneer the other guy wants to use white corian. it would look cool against the drivers and make a change from the usual black baffle.

understood,

please be sure to post pictures when you are finished, I am really excited to see what you end up with.

How are you guys going to decide on the curvature?

neutron7 · 21st December 2006, 05:08 AM

i will use the curvature provided by zaph which actually says "Waveguide profile - for turning your own on a lathe" he was kind enough to measure the plastic one perfectly and make a PDF of it. i will make a guide from the pdf to machine it from.

I bought the mcm guide for use as template and have a local turner make one out of wood. $20 each for labor.

I was thinking to build similar waveguide, but use
one Scan-speak 18S/8531G 7" Shielded Revelator instead of two seas woofers.
price is about the same and scan-speak is shielded and have lower Fs.
and i need shielded speakers.
Do you think one scan-speak 18S can perform as well as two CA18RNX woofers? I need a speaker that is able to play very loud and clear.
