Ok I finally got some time to start getting into MLSSA and measuring the TB 3" drivers.
http://www.earthwks.com/ns/m550.html
http://www.earthwks.com/ns/preamps.html modle 1021
http://www.mlssa.com.
Ok all of the measurments were taken with the mic 5ft off the floor stationary.
Distance to speaker from Mic was 2ft.
In the cabinets below.
6.5 (W) X 7.5 (H) X 7.25 (D)
with a 1" port 3/4 long.
A piece of insluation 15" long on the top,back and bottom only.

The MCM 606 was made as they dropped the TB line a while back and had a demand for the 319S1 which they could not get.So they had Lyeco make these.A steller unit to say the least.

The Models I have not measured in the cabinet but will.The W3-593S and W3-594S
As these are the modles that both Nuera and PE had made into a round frame and the W3-871S and the W3-879S was made from them.

The W3-881S PE had seen the W3-532S but wanted a round frame for the DIY.
Well not bad little driver just a little shy in the top end as you can see.
The difference between the 879 and the 871.
Large in responce as you can see but they are also differnt drivers completely.
The 879S has a different spyder,cone cone angle and phase plug lenght and shape over the 871S.
Yes cnot even close in anyway shape or form.

I did these to show you all that realy for the money any one of these will please your tastes just how high you can listen.
I have used these all as a fullrange no filter what so ever.Nothing.
The thing I am going to do is the 1.5 cabinets just installing the drivers above in pairs and using Jim Griffins designed 1.5 filter.
A 1.5mH and a 5.6 resistor.
This will be to show all those with making the 1.5 with other drivers other than the 871S what they will get in a responce.
Enjoy.
