That's the reason why you electronically delay the mains, to match the physical delay of the subs.

they will all be in a line horizontal, side by side, with the tweeters above each driver.

Please don't do that.

It dinna be the British Open, laddie, it's The Open.

I still use lead solder for electrical work. I don't drink water that's passed through wire.
Someone who does a lot of soldering would want to avoid lead solder, but someone who does a speaker every now and then probably need not be concerned.

If they need to be stripped of enamel and they break when you untwist them unwind enough from them to connect them again, after stripping the ends. It's not going to significantly affect the value.

That looks very good. It's not the species that matters, it's the number of full plies.

Why?

The coil wires are coated with enamel, not lacquer, and usually the last inch or so is left bare for soldering. If it's not you'd have to remove the enamel there.

Leaving the back open makes it a bandpass. Yes, it's louder in the upper bass, but at the expense of low bass, and at the risk of blowing the driver.

The point missed isn't how a 3015LF in a ported cab and a ten in a T24 compare, it's how a 3015LF in a ported cab compares to a 3015LF in a T48, or how a ten in a ported cab compares to a ten in a T24. In both cases the horn will be larger, but in both cases it will also be better.

I don't now or have ever owned a 100 foot speaker cable....

Nor should you. Even if the resistance losses are tolerable with that much length capacitance and inductance both will result in significant high frequency losses.

14 or 16 is sufficient. http://www.bcae1.com/images/swfs/speake ... istant.swf

If you look at the specs posted for current draw by amp manufacturers it's usually stated at 1/8 power. That's because amp manufacturers are aware that's as much continuous power that an amp is likely to be run at. QSC, for instance: 1/8 power represents typical maximum operating conditions 1/3 powe...

The Kappalite 3010LF was discontinued a while back, but a new version is now available. They call it the KL 3010LF, to distinguish it from the old version. It's a plug and play with any cabs that recommend the Kappalite 3010LF.

I’m planning to build two Tuba 30s 20”-22” single loaded with 3010LFs.

3012LFs are the same price, have higher maximum output.
