Pass SLOB Build Discussion

^^^^^^I'm headed that way also and just so happens I have the resistor module to cross these @ 100Hz and doing it now. You guys are great.

 

[mkane77g]

And now trying to figure how to do the 160Hz high pass

 

[mkane77g]

Is this what I need to make REW work. Thanks Amazon.com: miniDSP UMIK-1 USB Measurement Calibrated Microphone: Musical Instruments

Are you doing active or passive crossovers?

Here is an example with active crossover. Leave off the 1kHz Step EQ section, you don't need it with AN.

Op amp no party

Dolled up a bit. Wife doesn't like black cones.

Nice sound room. Do you listen from those chairs?

 

[nicoch58]

 

[WalterW]

hahaha

 

[mkane77g]

Depends what you're listening to. Just Imagine. Curtains drawn, fridge off, power @ 121v, no street lights for 5 miles, no other occupied dwellings within 1.7 miles. Damn quite around here, perfect for analog reproduction. And the listening chairs are out front of the baffles 11.764'

 

[Nelson Pass]

That 5 mile figure seems to lack the precision of the rest of your description.

 

[mkane77g]

Yea, sorry. Nearest stop sign's 5.1 miles out. So actually nearest light more like 4.5 miles away.

 

[scottjoplin]

Nice, how far to the nearest bus stop?

 

[mkane77g]

Close to 7 miles would be my guess.

 

[scottjoplin]

Has anyone measured the polar response?

 

[okankav]

I have found these:

where did you find this? I need this enclosure design for 10-12" drivers

Likewise. I plan to use a 10in FR driver and assume the baffle panel will need to be a larger but would appreciate some guidance on the required dimensions or any advice on how to calculate them?

I'll keep the bass driver and slot structure exactly as Nelson specified it in the drawings right at the start of this thread.

Cheers

Sorry guys, I really can't remember, perhaps this was the place:

Thanks Gyuri but I couldn't see anything about calculating baffle size.
