Woah. No one is in the chat. Normally it always says 1 person. I just figured the board stayed logged in. Not today

Only "concern" with it is the low input voltage/output voltage capability. If you have a cheap amp your gain may need to be in the region where thermal noise becomes an issue. Coming from a headunit is no big deal, but direct from an Ipod like device can be.

Balt I'll assume by sound you mean you'd rather use it as acoustically you sure as shit aren't going to hear a difference. European Beech Ply is very strong and ridiculously expensive. The guy at the wood shop recommended it over Birch for strength. Called Baltic Birch here. Love it. In fact cut some tonight

Run it. 1000w won't be audibly different to you. Definitely would make a difference, just not big enough to bother with. The box will have a bigger impact.

Too much not water, rofl

That'll have "bite" AND taste good. Assuming of course you use at least reasonable tequila. ie, nothing with the Cuervo lable

Too much sweet and not enough booze. Try: Rocks glass full of ice Juice one lime 2 shots tequila .5 shot/splash of Cointreau Sweet syrup to taste. none is necessary with good limes, but we sure the fuck rarely get those.

BOO. Frozen marg's are a waste and your liquor to mixer quantities are really weak.

I thought you liked to jerk off in the rain.

It's instantaneous and on the fly when connected...except you can only click on one "channel" at a time so listening to them requires you to click on all 4 and make the change. Each one happens in real time and there is a defeat so you can focus on each side independently really easily. The user interface is uber simple as well. There are two ways to input a crossover and slope. One the 6,12,18...48dB and type, the other is to use a custom biquad (which with a spreadsheet I can email you is super easy). The biquads allow all sorts of fun filters. On one of the channels in my boat I have some coaxials where JL thought that having the tweets be more lively than I like was logical. I wrote a shelf filter and knocked down their artificial boost to really make them sound better. All sorts of fun flexibility when you have a modular DSP.

There is a big fan shooting at it as well. Pre-fan I couldn't touch the aluminum plate for the bash plate amp. Now that is cooler than the motor but that took a few hours to heat soak.

With in reason, due to the cooling channels, as long as the cone is moving the coil is cool enough. Can I use it as a hot-plate? Need MO POWA!

I keep meaning to write a macro for our scanning system to make the Klippel look like a children's toy....but that takes time as there are all sorts of audio specific algorithms they use I'd have to synthesize. I will say this though. Serious manufacturers rely on the Klippel only for rudimentary measurements. Their engineering meat comes from a different tool.

With in reason, due to the cooling channels, as long as the cone is moving the coil is cool enough. The motor is sitting on carpet... It isn't glue melting hot.

Demonstration of near field analysis results for small audio brands? Not quite. We measure surface velocity. So any dynamics portion of the FE, but without any erronic assumptions that FE models make. When I first joined here I was maybe still working for Bruel & Kjaer in which case I had closets full of the worlds best speaker testing stuff including to do near field work. At this point I still have a B&K mic and spectrum analyzer, but no way of performing a simulated free field measurement. It isn't terrible hard to get there, but I just haven't had the need.

And the motor is HOT

Sorry, I know you guys aren't morons but can see one click in the thread and misquote me or misread me badly.

That being said it is fun to drive it through resonance and see how much more violently the whole structure reacts. Serious energy amplification.* *all speakers do this to some extent so don't read that as a negative, just fun to see.

If I had a SV right now I'd take some data on it that would make FEA stuff look like childs play. It won't help me or Aaron though so it probably won't happen. Cost $1000 just to ship it here and then $1000 back so I'd need to have a different reason to spend that much company dough to have fun.

Something else changed then which of course is hard to avoid.

I have my personal measuring equipment here but no company stuff. ie, no lasers but plenty of ways to measure acoutics.

The cone is slightly warm, the amp uber hot, and I have a big ass fan blowing on both. It's noticeably moving further now though. Of course it's also had more than 250,000 1" p-p motions as well.

As I mentioned before the cheapest option will either be to sell your headunit and buy something like a used Pioneer 880prs....amusingly I sold mine this morning...or to buy a 2x4 miniDSP which will actually give you WAY more processing power but require a computer to make changes. I use a pair of those in my boat and they are ultra flexible. In your case you'd be out $109+shipping from Asia for one. $99 for the DSP and $10 for a 4chn Advanced plugin.

epends on the quality of the ply. Cheap ply is worse than mdf, good baltic birch ply (~$75/sheet) is better. I'll assume by sound you mean you'd rather use it as acoustically you sure as shit aren't going to hear a difference.

Freaky fun. Night and water are two things I love together.
