Your Welcome!

I'll place data on the ESR thread.

I'm a little worried about testing the drivers T/S params (I use the added-mass tech. and adding any mass to these diaphrams is a bit worrysome).

Default Loose Parts?

Anybody else receive a pair of these with loose plastic rings on the perimeter of the surround? One of mine is detatched 1/2 of the way around while the other is loose along about 1/4 of its length. I would just glue it back down except that the surround material is bonded to the metal frame under this ring. There's no telling what might happen over time if I chose the wrong adhesive. Bummer

make sure you complain... if they don't get feedback they can't know to tighten their QC.

Default hybrid Karlson/Transmission Line cabinet

I have built a number of hybrid Karlson/Transmission Line cabinets for a number of Fostex drivers. Currently I am running a set of fe166e's as well as fe126e's in these cabinets. I have run both fe167's as well as fe127's in these cabinets. I have included a photo of an early version of the cabinet used for the fe 127/126e driver. The benefit of this cabinet is that it provides a significant load to both sides of the driver. This then generates a very good impedance match between the driver and the air in the room which results in excellent output with the limited excersion these drivers have.
This idea is not the norm that I have seen on these forums and is very different from what common wisdom would call for but the cabinet is compact while its structure is very ridgid and bass response is better than I had hoped for. I do not have any measurements to supply but I have previously built ML TL for both of these (all four) drivers and find the hybrid K-Line to have superiour bass performance. Best regards Moray James. I don't know if the photo will attach but if it does you can get the general idea of this design. can't seem to paste the photo perhaps someone could walk me through it?

Per the Madisound web site the FE166ES-R is old out.

My drivers arrived in perfect conditon. I checked the plastic surround retainer ring this morning and it was tight all arround. I have been playing them free air sitting on a table for the past couple days to assist with breaking them.

I should get my cut Baltic Birch from the lumber yard next week. The fun begins.

Default All's Well That Ends Well

Regarding those defective drivers - Madisound must have kept a little something in reserve. I called first thing Monday morning about the loose plastic rings (I'm sure there's a technical term for them) and was informed by sales that they were, indeed, sold out. A small amount of pressing (barely twisted the guy's arm) got me forwarded to the service department, where I was informed that they did have ESR's and would swap out my set. (Can't say how many reserve sets they might have - didn't ask. And they probably wouldn't have told me if I had).

Madisound issued a call tag, which saved me the cost of shipping them back and sent out the replacements the same day - should be here on Friday! I'm impressed. If only the rest of the world operated this way...

Apparently, we've caused quite a stir over these drivers. The service rep commented that this special order has been keeping them busy. Hopefully, this bodes well for more goodies. (Which makes me wonder: Where do you guys keep all your finished projects? If I get too head over heels with this stuff, I might have to open a B&B with a hi-fi in every room!)


I know this is off topic but could someone explain how to quote another message? Looked at the FAQ and searched to no avail. - Thanks!

I try to give them away to friends or sell them, profit free. I just want to make room for new stuff.
