Dont suppose you have a photo of what a LT looks like assembled?

i just had a look at the LT calculator online as it was readily available. the Caps and resistors is there any recommendation behind picking them? ie 250v or 400v and 10w and 5w etc.

THe triangle configuration confuses me a little as well, as it goes from positive from the amp, to negative, then splits?

ok, as it happens, i just happen to have a 2.1ch class d amp board sitting in a box and a TEBM65. If i can figure out this LT filter, i could boost the 3.5inch in the 0.06 cuft box and i think the low pass will kick in around 100-140hz so it will act like a ghetto sub. as for the TEBM35's they can operate around that 80-100hz. if memory serves me correct, you would generally need to use a LT in a sealed box, is that correct?

Either that or the TEBM's with a oval shaped PR each (thinking from PUI Audio). They (PUI Audio) did have some interesting looking and sounding drivers as well, just not a lot of information and no reviews to speak of.

I had some scrap ply strips and glued them up to make a few 12mm panels and created an overall box with internal dimensions of 300x66x90mm (overall 0.06cuft)

Any thoughts @5th element @xrk971

The triangle is a circuit symbol for an opamp. The zigzag lines are resistors and the two lines capacitors. The other lines are the connecting wires, or traces on a PCB that link everything together.

Google opa2134 and look at the datasheet for an opamp. These aren't passive devices. They need a power supply. Or NE5532.

LTs only work with sealed enclosures. When designing the component values make sure to keep the resistor values low to minimise noise. Say aim to keep them between 500 and 10,000 ohms and size the capacitors to fit.
What the hell are you screamin' for? Every five minutes there's a bomb or somethin'! I'm leavin! bzzzz! Now with website! www.5een.co.uk under construction.

Right, I would never have guessed the opamp. Might be best I Photoshop up the parts and how I think they sit and get power and post it to see if I understand correctly.
