I hadn't really decided on either, but consider the 2nd bedroom claimed. Thanks.

I think wall + earplugs + alcohol should be more than sufficient to deal with snoring.

We need to get some of the head-case muscle to persuade the concrete guys to reschedule the slab pour. It would be a real shame if you're not able to make it. Related: Is there anybody who would be nice enough to split a room to reduce costs? I'm one of the few planning to be there Thursday to Monday, so I'll probably book the room myself.

Where's the puke emoticon when you need it.

Just don't start shaking me violently when I'm taking a drunken nap again, okay?

I'm planning on flying back monday, I could easily make it a later flight if there's still gonna be some people around most of the day.

Or get somebody else to divert attention away from you. I was the drunk kid at DanJam until you went and outdid me at CanJam.

Wow, being within stumble distance of Cigar City sounds friggin amazing. We're so getting crappyjones hammered. Dang, that's too bad.

I've always been able to make it change direction at will.

i would hate to be a pilot when the plane becomes a zombie.

That's horrible. How are you holding up?

Yeah that's a pretty sweet deal Brent, think I'll need to go with that. Not thrilled on getting up early for both flights, but even factoring in gas and a new battery for the car that's still less than what it would cost to fly from ATL.

Yay for all I say.

Any bets as to who would get to Tampa first if they both left at the same time: Crappy flying Spirit, or Brent driving down?

I've secured my travel fund, and I've got a green light to take time off, so I'm officially on for this party meet.

Removing it just boosts the treble, which isn't something I really want.

I don't think so, at least not significantly. The sim doesn't match up as closely to the measurements I took of a very high serial # pair, but the difference is rather small and would make sense with 5-10% tolerances on the cap and inductor. The real question is what the nominal values are supposed to be. I suppose one could reasonably go with the nearest common value.

No idea, never really felt like trying to make a complete model of the driver. I don't think it has any significant amount of inductance, at least not relative to the filter, since the resistor model matched the acoustic measurements pretty closely.

DCR is only 5.6 ohms.

It's long overdue, but I finally decided to go and figure out exactly how the filter PCB in the K1000 affects the sound. As has already been established, it is a low Q notch filter in the treble region, with a noticeable effect on the sound. It consists of an inductor, a resistor and a capacitor in parallel with each other, and the filter is in series with the driver. The values I measured were 7.1mH, 88.9R and 0.168uF. The resistor markings clearly show it as an 88.7R 1% resistor, but the other two would require assumptions towards their nominal value. Simulating the filter based on a 120 ohm impedance gave results that conflicted with the measurements I took of the K1000 with and without the filter installed. Measuring the impedance showed it varies from 130 ohms at 1KHz to over 140 ohms at 20KHz, so I put 135 ohms as a compromise and then the simulation and actual measurements agreed with each other. Based on both the filter simulation and the actual driver measurements, it seems the notch filter is centered around 4.6KHz with 4.4dB attenuation, and has a bandwidth from approximately 2KHz to 11KHz.

Money, usually.

Finally took proper measurements on the K1000 filter board, may do some tweaking to it.

Had an amusing thought last time I was ordering parts, and decided to change the connector on my K1000:

Been thinking about this the past couple days, I'm gonna make it happen one way or another. Gonna see what I can unload on ebay, craigslist, or head-fi and then I'll book a flight.
