I build these drivers in a small cabinet because I want use them as a near field monitor coupled with a sub-woofer. For such a small speakers they throw a large sound stage when compared with my Open baffle speakers, that says a lot about the drivers. At this early stage(<10hrs usage) the treble needs to be tamed, I think it will settle down a little after more hours of usage. I prefer them to my FE167 Fostex.

The cabinet dimensions are 14cm*23cm*21cm(w*H*D), I use a wool fibre for damping

I got mine from the same place that ttan98 did. Thanks ttan98 for the details of your speakers. Has anyone got any thoughts or ideas about putting a pair in a Fonken cabinet? I quite like the look of those. I wouldn't have any idea of how to calculate the dimensions bearing in mind the specific parameters of these Chinese speakers. Would Fonkens be something to consider?

Going by the factory spec., I'd say borderline. Incidentally, I'd be rather careful of assuming the factory specs. are accurate too; there's a glaring inconsistancy between Vas & B*L for example. If the Vas figure is right, then B*L must be rather lower than stated, & visa versa. Generally speaking, I'd be inclined to suspect the B*L figure as being the more accurate as it's easier to measure. What that says about the rest of the figures though is anyones guess. The Audio Nirvanas, which AFAIK are out of the same factory, have often had T/S specs. well away from the published data sheets, so YMMV.

Anyway, Dave can speak best for the Fonken loads; a modified version of the prime might (might) do OK. As they're limited availability etc., I'm not sure it'd be worth doing a dedicated design. Dave?

A ~7 3/4 litre sealed box would give you a nice 0.707 Qtc alignment with a 52Hz F10 based on the factory specs (with Vas adjusted).

It will work OK if the factory numbers are close.

See the attachment for required adjustments to the vents.

Hello - I have a pair of these drivers and would like to put them into a simple horn. Has anyone got any ideas?

They might do OK in the Frugel-horn.
