I need to measure the Thiele and Small parameters.
I calibrated my sound card.
I calibrated my measure.
I use 50g playload (mms= 100g)
Uses resitances in my soundcard inputs, an amp and a resistance of 16 ohms Rsense. I tried different resistance value. It's still the same error.
RE My hp fact...
I just bought a DC and did a first typical calibration , i am using SVS PB12-NSD and i was hoping to see a decent flat curve but i see it is more or less better after 35Hz . is it good? how can i improve further any advice?
I see the response starts very low is it normal?

A friend just picked up a Klipsch KW-120-THX woofer for a steal. Unfortunately TS parameterss for this woofer haven't been easy to come by on the net. I can't seem to find box dimensions either.
Do any of you guys have any of this info or know of someone in the DC area with a test rig to...
This is a little puzzling... voice coil measures 3.7 ohms, but I have to enter a value of 3.3 for REW to calculate TS parameters, and REW spits out Re of 4.06 ohms, which seems high? Any ideas if this is an issue with my test rig?
I have been thinking about a home theater in my basement for a couple of years now. I finally got around to starting to build a space out this spring. I'm now at the "finishing" stage and am stuck. I have browsed a lot of build threads and seen quite a few pictures.
This is the space as it...
Oh say can you hear, by the dawn’s early light!
It’s hard to believe that four years ago the epicenter of the free world and capitalism, not to mention loads of folks with deep pockets, was completely devoid of a festival to showcase audio products. Luckily for those of us in the Mid-Atlantic...
How do I place the mic to measure my DIY Tannoys DC's ( 3839 in 140 L reflex cabinet )
Did some measurements ( nearfield ) with Umik-1 but see some strange dips and clips .
The sound is great ! but want to get the max out of it .
Growing up I'd always been a DC fan. Seemed to me their comics and characters were better, that was the '70's. Now that we have been thoroughly inundated with comic to film adaptions and I am now leaning toward Marvel.
Aside from '78 & '80 Superman, '05 & '08 Batman and maybe '09 Watchmen...
SO I finally got my BFD hooked up last night, and have a descent graph now. In order to keep electrical consumption to a minimum, I am using the switched ports on the back of my receiver to fire off an ac relay that is hooked in to mains (Receiver is only allowed to do 1a switched) I then have...
