I drop builders from the list only at their request. As for more modern retail cabinets, there have been very few significant changes to them, other than upgraded driver performance. I account for that by periodically revising the recommended drivers list, so to the extent that commercial cabs are g...

FWIW the LAB became a viable option when neo driver prices went nuts. LAB prices are up too these days, so shop around for equivalent neo drivers if weight is a concern.

There's no such thing as power hungry, other than with very low sensitivity drivers, which wouldn't be within spec range anyway. You just won't get what a high Pe long xMax driver is capable of if you don't have enough power, which often means you're spending more than you have to. Where driver comp...

Either will work, the 800 will have more output in the lows with sufficient power, the 700 is stronger in the midbass.

Have you read this? https://billfitzmaurice.info/forum/viewtopic.php?t=398 Part and parcel of proper sub placement is that they not be directionally locatable. That means crossing at 120Hz or lower, but no lower than necessary, to take the low frequency load off the mains. BTW, your JBLs are down 3d...

60v. It's set to the Pe or Xmax limit, whichever is lower.

Personally I wouldn't be mixing drivers, which can result in having to use different EQ and limiting, which can lead to driver killing mistakes. Pick one and stick with it.

This is for an OTop 8??

Ideally you want to run subs up to where the tops reach their excursion limit at full power, if not a little higher. Knowing where that is can be a problem.

Getting into the fine details of horn design is a topic that falls beyond the scope of our purpose here, which is to help people choose, build and use the right cabs for their needs. If you want to get into those fine details learn how to use HornResp. There are many on line sources to help with tha...

Don't. Just use a driver with the correct specs. Lowering Fs in a horn is not only unnecessary, it can be detrimental.

It does, because IMO the Simplexx porting arrangement is the best. All that differs is that they were specifically sized and tuned for the Celestion drivers.

This is the assembly video for the enclosure I designed for Celestion, using the TSQ 2145 driver. Plans are on their site, as are plans for their TSQ 1845 driver. https://www.youtube.com/watch?v=UYieLZ0XNbs

Looks OK, you'd just need to wire them series/parallel as required to get the correct impedance. You would not be able to substitute them for 8 ohm 6A drivers.

I would not use solid wood.
