zaph's silverflute/vifa speaker

for frequency response data. Also please note the comments on the Silver Flute driver. 1,800 hz seems to be the best crossover point for this driver. You'll need a not so cheap tweeter for this. An MTM arrangement might be a knockout, crossed over at that 1.8k.

<shrug> Oh well. To each his own...

Orient Express FR

An externally hosted image should be here but it was not working when we last tested it.

OT, but Undefinition, any chance you'd make a center channel version of the Orient Express? I'm building a 5.1 surround set or Express', but I can't figure out how to make the last piece. Also, what version of the Silver Flute should I use? Solen has two, the 4 ohm and the 8-ohm one.

I have gotten a few requests for a center channel. Originally, I'd just say build one more TM and stand it up above or below your screen. Of course, that's not exactly the most glamorous setup, but it would definitely put out the right sound. And hey, we're on a budget here!

However, since Chainenoble was so generous to give me a pair of the woofers, I can certainly design a sideways MTM. I foresee two issues with this, but I don't know how big of a problem these would be for most people:
1. The Ohms load would be significantly lower than the normal TM version (theoretically half), since the woofers would be in parallel. This could be a strain on some HT receivers.
2. With two woofers in parallel, the output is [technically] 6 dB louder than a single woofer. This isn't a huge deal, but it does mean that the person setting up the home theater will have to compensate for this difference in volume between the center channel and all others.

So to those who were asking about a center channel, I ask that you chime in if either of those things are concerned or how badly you need the cosmetic look of a horizontal MTM center channel.

Thanks,
Paul

I apologize for the hijack, but has anybody been having trouble viewing Zaph's blog? Seems like the content simply disappeared.

Yeah...the receivers I'm seen have a min. of 6 ohms...don't know if it's a good idea. If building the vertical version (for center use), which side should the tweeter be on?

Thanks, Brendan

Question about the special sale shielded 5.5" silver flutes at madisound:
Can you remove the shielding parts and end up with the same thing as the unshielded 5.5" silver flute? I don't know if manufacturer's just add a magnet and bucket for the shielded versions or if there are other changes. Anyone have insight on this?

Hi,

No. The cone and coil appear to be identical. From the numbers
you can ascertain the shielded version has a somewhat smaller
main magnet than the unshielded version but not a lot smaller.

thanks paul

i just noticed you have finished the sheilded version(china syndrome) .it sounds like it was much more work than expected!much appreciated.maybe this will get my **** into gear and build
a pair.

another option that is good

use the 2 silverflutes and a Vifa D26NC-55-06 in a WTW arrangenment and use the recommended volume and then have madisound create the crossover this should give a very good result and the Vifa tweeter there are many available on ebay
