Design for Silver Flute W14

[coolkhoa]

Hi guys,

First of all, some info on this well-received driver. I have read over Zaph's Silver Flute design but wonder if there's a cheaper tweeter that mates well with it. As for the crossover, I want something simpler but adequate...how about a 1st order Butterworth?

Comments are appreciated.

I have built a MTM & Daline TL using Silver Flute W14RC25-08 and Seas H883 tweeter and I am very happy with them.
Crossover has been designed by Madisound (LEAP).
Let me know if you are interested...

Just a simple question:
What's the crossover topology and crossover frequency?

Attached the schema of the LEAP crossover.
BTW I've seen this morning on Madisound forum that Rick Graig has done measurments of the shielded W14RC25-08, he proposes to send results by mail.
This is what he wrote :
"I did a near-field test on the 5.5" shielded version in a sealed box. This woofer is perfect for this application if you need a compact speaker to go with your sub(s) in a HT/music system. F3=76hz, F10=47hz. I'm combining it with the JP3 ribbon. E-mail me for the response curve."

WKR,
Lionel

The speaker and the external crossover.
Daline TL gives good results in term of low frequencies response.

The 2 Silver Flute W14RC25-08 and the Seas H883...
Sanding and painting need to be finished but it's still too cold in my basement !

The event and the crossover.
Need finition too...

Thanks, Lionel! It was especially generous of you to provide the LEAP crossover schematic that was paid for.

You're welcome.
It's small contribution compared to the huge amount of precious information you can find here.

After listening to the W20s and assuming that the W14s have similar yet, more extended sound, I think that based on sound characterstics the Audax TW01E1 may sound sweet with that woofer...I'll haul up my old stuff to see...

I'm thinking of using the shielded Silver Flute, but it's really better in a sealed box...with less bass "punch." Then I'd also need a cheap shielded tweet...any ideas?

Edit: Thanks Bose(o)...I posted this a few minutes after your response.

W14RC25-08 : Unshielded version in a 11 liters vented box.

W14RC25-S-08 : shielded version in a 11 liters closed enclosure.

This driver in a sealed box of this size would yield a Qtc of about 0.66. I'd rather go with a smaller box and higher Q (up to about 0.8). So I think a 7-liter (0.25 cu ft) cabinet is good.

Well...I'm not sure about anyone else...but I like the sound of my tweet (still) more than my Seas 19TNF...the Silver flutes are very nice sounding too. I have only used four tweeters in my life...Audax TW01E1, Peerless DT80C04, Illusion Audio TN-25, Seas 19TNF08. Seas is best for accuracy...Audax have a brightness in the right spot to give that natural flare that metallic instruments possess in live.

I need a good shielded tweeter to go with the Silver Flutes, preferably under $20. I'm really only considering Seas and Vifa because of their consistency (well, Axon is an alternative).

If I go with the Axon T1, I might as well base the system on Axon's excellent 6S3 6.5" midbass...

Audax TM025F1 and TM025F9 are shielded and cost $19.10 at Madisound.

Can't use Audax...I heard they won't be doing DIY much longer...what happens if I want to commercialize my product?

Seriously...

I'm not sure how these tweeters would match with the silver flutes, but here's some good bang for the buck tweets

NORTH D25-06S ($36 per matched pair)

Dayton Silkies ($16.75 each)

GR Research T1's ($30 per matched pair)
http://www.gr-research.com/drivers.htm#grt1

I, myself, am planning on using the w14 with the fountek ribbon tweeters, but those are $81 each (I got some help from Rick Craig, he's thinking about putting out a kit with this combo.)

 

[diamdiam]

It's actually $33 for the gr research. The price I listed is for the unshielded.
