Is a Falcon a TL?

Yes. Desktop labyrinth. One of the Woden Baby Lab set.

Ha ha, fantastic thanks everyone! 'High Ratio vents' makes a lot more sense! 🙂
I'm now doing a bit of reading tonight to try and understand their advantages.

And i never took typing. You will note on yout keyboatd that T is next to R and Y is next to T.

Here are plans.

Thanks Dave, VERY much appreciated!!

I see the photo you posted of the Falcon shows the port on the rear. Assuming the port dimensions are kept the same, would it be detrimental to move the port to the rear?

My drivers have turned up earlier than expected in Australia! I best get on with cabinets! They sure are cute little drivers!

Not an issue unless you mount them too close to a wall. A better way to think about it is to mount the driver on the back.

Slightly OT but it puts a smile on my face. I hope he gets something close to that.

Hi everyone;
Don't know if it is still interesting for anyone, I found the mentioned test of the german magazine HobbyHifi under the description of the SOL at an retailer:

If there are some problems with translating this text I may help; PN me 🙂

Anyone can comment the SOL Freq. Response curve

From the curve derived from the above reference(thks S4m) and another source I came across, I believe there is rise in the freq. response curve above 5khz to 20Khz from on axis measurement.
My question is does anyone find the freq. rise irritating if it not control via a Low Pass filter to remove it? If not how do you control it if not all.

Toe them in/out ~15*. Most FR drivers with rising response will be nearly flat around 15*. The extra highs splashing around the room will provide "air".

+1 Some of the more extreme rising response 'FR' drivers can require 30+ degrees in a highly reflective ['bright'] room.

No more stock?

It looks like all of the units may have been sold - there are no more on EBay nor any of the Fostex resellers I've checked (Madisound etc.). I've been looking at these for a while and grabbed two pairs of 16ohm last week.

 

[chrisb]

wouldn't be atypical of Fostex's "special editions" - too bad, this one was quite interesting

What? You NEVER toe-in a lowther 😀

I find them nearly unlistenable without orienting them carefully and picking a good sweet spot. But with that done, on the right content, they're magic.

 

[xrk971]

Never mind the FE103-SOL, there's bigger fish to fry with the FE108-SOL:

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

 

[chrisb]

Could be a excellent driver, but perhaps subject to the same limited production / distribution for which Fostex is well known?

 

[planet10]

I just put a pair of those on the break-in bench. Very nice looking drivers.

Hi Dave, are you talking about FE108-sol? any impressions so far?

Thanks in advance,

 

[planet10]

I didn't get much chance to listen to them before shipping them to the customer. He is pleased with them.

They are an impressive looking driver and the listening i did get did not reveal anything nasty.

[Scottmoose]

That's good. 🙂 Judging from the pictures, the box cut-out will need one heck of a chamfer for decent air-flow.

Only nearly?! 😉

Needs the $0.98 and phase plug tweaks for me to get there.
