Will you do this:

1. Shellac the whole thing,
2. Mask off the front baffle,
3. Shellac tint the cab,
4. Shellac the whole thing,
5. Poly the whole thing?

I ask because I have a maple baffle...

There's tons of examples of driver measurements out there. Tip should slowly understand the basics and then build up to a level of understanding XO design. If that's what he wants to do.

Correct, except below Fc the slopes are both "good enough". Whether 12 or 24db they both push down excursion faster than it rises. And again, talking about protection, not HD. There may be other...

On my phone so not a great response, but when it comes to protection LR2 transfer function is the safest. That's different that rising HD which may rise faster than 12db/oct.

That's an honest 93db at 8ohm in free space down to 100hz and a slight roll off down to 70hz and sealed! Not many speaker that size can claim that.

From a Google search the HTM1 seems to be a center channel speaker. You plan to use the 1099 as LR and keep your HTM1 center? I haven't heard that speaker so I'm not sure about the match. But it...

Its been discussed before, but here's the brief reasoning.

Around these parts most say nothing is overkill. I'd actually agree this time, they should make a good surround provided the vertical coverage isn't to limited. I'll have to see what can be done...

Yes I am. That's a great example of how you can't use eq to do what you want. 40hx is below the port tuning on the 1099 so you couldn't safely eq it flat to 40. 50hz would probably work, but it does...

It's difficult and I'd need both the MBM and speaker for a while to develope it. Active is easy at these frequencies because they're flat and predictable. Impedance is a mess however. At higher...

Just to get extension. Also reduces excursion at the bottom of the passband. Sealed is fine too, just takes a higher XO to the subs which one benefit of an MBM is to cross lower. So it depends.

Whether BB or MDF doesn't matter to me, more what other people would want.

Slot port is always best IMO.

Golden ratio is the best, but might not be of a benefit in the MB range, and it can make for an awkward size. I'd suggest a width that matches some of the existing diysg designs. The height and...

Basically, more clarity in the midrange on the 1099, but more laid back / full with the Cinema 10. Very subtle differences though.
