Enclosure Suggestion???

[fringy75]

Hi all.

I picked up a couple of widerange speakers from the New Zealand version of ebay, specs are below. Manufacturer is unknown. Can anyone suggest a enclosure that they feel would work? I also have no other t/s detail.

One pair of Neodymium magnet, paper cone Taiwanese-made wideband speakers.

Similar to Fostex fullrange speakers with a balanced and smooth frequency response. Reports had some prefer them to Lowthers.

106mm driver faceplate
94mm baffle hole size

Approx 89dB efficient
68hz - 20Khz
Imp: 4ohm
Fs: 68Hz
Qt: 0.48
Vas: 7.68 l
Xmax 2mm
10w rated, 15w music
Surround: PU
Cone: Paper

What basic shape of cabinet are you thinking about?

Tall and narrow
Wide and shallow
Standard stubby
Or...?

Hi Cal.

To be honest i don't mind, WAF in the room that my audio sits in is not an issue.

I have an wide taste in music, so could be classical one minute followed by Pink Floyd! although saying that I do have a preference for female vocal jazz.

Room is 5 metres wide by 8 long by 2.4 high and will be run from a Topping TP30 T amp.

Sounds like a Cornu candidate.

Thanks Cal. I will take a read of the 75 pages of posts 🙂

Only 19 pages if you set it to 40 posts per page. 😉

You have musical tastes very similar to mine. I will agree with Cal and suggest the Cornu for this driver (standard 28 in size x 4.5 in deep) and also another option is to go with a FH3-like design. http://www.diyaudio.com/forums/full-range/227460-fh3-inspired-foam-core-mini-build.html I had very good luck scaling the FH3 down to work with the Vifa TC9FD. Btw, the frame on this driver looks just like a Vifa/Peerless (probably a custom run by Peerless for this company). The FH3-like design will have better spatial imaging soundstage but Cornu will fill space better and have wider sweetspot. Both are great for female vocals. Good luck.

Cornu.
It makes sense in so many ways unless you are building fully from wood and then the options other than Cornu are endless. I think it's the frontrunner due to it's ability to have a working model in a short number of hours. Due to it's nature, it's not going to sound a lot different in a wood cabinet than if it's foam core with wood baffles. That's hard to say with other alignments. Hey man, you're the genius here, run with it.

Hello,
may be the CORNET would be a choise,
bass down 34 Hz, tube amp possible,
look measurements and feedback:

Thanks guys for the suggestions. Xrk971, I have read the whole thread on foamcore enclosures, and I have to admit that they do sound like fun 🙂

The great thing is that I can always build multiple enclosures and play.

Foam core is great for quickly trying many designs. I hear it is a little expensive in Australia though, here in the States we enjoy $1/sheet as it is actually made here.

I am listening to my Cornu right now and Sade sounds fantastic on it. Given how easy it is to build, you cannot NOT try it.
