Default FE208EZ

LABYRINTH - Platinum

As I'm not a woodworker I would not hazard trying to build even a simple loudspeaker cabinet yet alone a complex one. However, I am capable of putting together a kit.

Has anyone any experience of the Fostex FE208EZ ?

I'm tempted to try a full range driver to see how no crossover affects the general sound of a loudspeaker. The FE208EZ however only extends to 20kHz. Would this too benefit from a tweeter and a dreaded crossover ?

Do bear in mind that I currently have a pair of B&W 683's which are already impressive.

I need something that will be capable of handling my 100W amp.

I think there is a mistake in the specs, Fostex rate that driver to 14kHz, which probably would need a tweeter. I don't think anyone past puberty can hear 20kHz though many claim to. Download a signal generator and test yourself.

I could up to about 2 years back, but I've dropped off since then to about 19KHz. That's not going to last much longer either I suspect, since I'm 34 & extremely lucky for it to have lasted as long as that.

Anyway, the FE208ESigma is about done by 12KHz; no bad thing since Fostex concentrated on getting the low end & midband right, leaving the HF to be covered by something better adapted for the purpose. The T90a is the minimum needed to do justice to it.

The 'labyrinth' as Wilmslow call it, or as everybody else in the known universe refers to it the 'factory back loaded horn' is one of Fostex's better enclosure efforts, although MDF is not what you want for it. A good ply is essential. Wilmslow can supply that, or you can make it yourself since the plans are freely available. It's not the best box design out there, but it's a solid one & a decent performer. If you don't want to use a supertweeter to fill in the HF, the FE206En will work fine in that enclosure. Note however there is still an XO there: it's just that it's a mechanical one, not electrical.

They won't sound like B&Ws, that's for certain. As for 'capable of handling your 100w amp', that is entirely dependent upon how far you turn the volume knob. They don't require anything like that. About 3w is all that is needed since they're about 98dB 1m/w. They were designed largely for SET amps & class A designs, so unless your 100w job is something from Pass Labs, McIntosh, Accuphase or similar, they're not going to sound great. System matching is key. You can use high resistance wiring to improve the impedance match (i.e. provide the speakers with something akin to what they were designed for) though, so this isn't an instant turn-off.

Yes, not far off a T90a, but it's an internal-mount unit.

It seems to me that the Labyrinth is the Fostex designed cabinet for the 206E.

The 208 sigma cabinet is this :-

I built this cab, but used the 206E driver.

T90a not 900. Much more sensible.

I think a great budget solution is the Fe206en as Scottmoose suggested. I have a couple in Vulcan cabs and find them very pleasing.
