Louder yes, but it's best to have the bass feed in the monitors high passed at 120 to 160 Hz. Side fills too. The backline provides all the low end either you or your band mates need on stage. It's only the directional frequencies, above 120 Hz, that need to be be spread around better. Part of the problem with spreading cabs and running full range into monitors and side fills is that it not only provides more mids and highs that you want but it also provides more lows that in most cases you don't. The case where you might need lows is on a huge stage outdoors. Feel free to run full range at Wembley. 😉

FWIW don't split cabs. When you do it creates hot and cold zones in the lows, AKA 'Power Alley'. If you want to be heard on the other side of the stage aim one cab at yourself, the other across the stage. That aims directional mids and highs so they can be heard, without creating a power alley. This explains. It references PA subs, but applies to bass cabs as well: https://www.prosoundweb.com/the-power-alley-discussion-solutions-to-the-troubling-interaction-of-subwoofers/

Where tone is concerned reggae isn't low end strong in the 40-60Hz range, it's midbass strong in the 60-90Hz range. That's because the benchmark reggae cab, the SVT 810, isn't low end strong, it's midbass strong. It's also loud. The reason it's loud is the eight drivers, which have a combined cone displacement of 1300cc. If you want to get SVT volume without the SVT size and weight the way to do it is with high displacement drivers. The highest displacement drivers available in commercial cabs are those used by Barefaced. Four Barefaced tens or two Barefaced twelves will go almost as loud as an SVT 810.

That's where the driver specs come in. The ideal tuning for contemporary high quality fifteens will be closer to 45 Hz, but as the saying goes they don't make them like they used to, so 53 Hz may be best for that driver. This and five minutes is all you need. https://www.parts-express.com/Dayton-Audio-DATS-V3-Computer-Based-Audio-Component-Test-System-390-807?quantity=1

Having seen some real nightmares I never assume that anyone knew what they were doing without checking it for myself. 😉 By and large most fifteens work best with cab tuning of 45-50Hz. That can be confirmed from the cab dimensions alone.

A hole is a port. A hole with a tube or extension behind it is a ducted port. Over the decades the 'ducted' part of the name has been dropped from common usage. A hole is still technically a ducted port, with the duct length being the thickness of the panel it goes through. The longer the duct the smaller the port will be and the smaller the cab may be for a given tuning frequency. The smaller the port the higher the velocity of the air vibrating within it. With sufficient velocity you can hear that air mass vibrating, so there is a point where it can be too small. Your cab may be fine, it may not, which can be determined with the exact cab dimensions and the driver specs.

They were actually Canada's Fender. They were fairly popular as a less expensive alternative to Fender back in the 60s-70s, especially in the states that bordered Ontario and Quebec. I bet thousands made the trip across the bridge that connects Windsor, Ontario with Detroit. Back in the day crossing the border entailed not much more than a wave at the agents, and no one paid much attention to what was in your car.

Far more often than not that's true. You can combine just about any two cabs and they'll sound better than either one on its own. That's because the two will be louder than one at the same amp setting, and louder is subjectively better. However, the only way one can know if X+Y works better than, or even as well as, X+X or Y+Y, is to try all three combinations side by side. In some twenty-five years of seeing these discussions I can't recall a single instance where someone actually did so.

Horizontal 210s, or horizontal any ten or twelve configuration, were originally created because valve amps were wide. It's not like the audio community didn't know that vertical was better. St. Paul's Cathedral in London was equipped with vertical arrays in 1949. They were only recently upgraded, with new vertical arrays. http://www.pamphonic.co.uk/029_wireless_world_1952_St_Pauls.PDF Now that amps are much narrower speaker manufacturers are finally making available what they should have in the first place.

I haven't come across the tweeter option at BF. I recommend the Eminence BGH25-8, in part because it rolls off above 10kHz, where there's no useful content. The other part is because with 4th order filtering it can be run down to 2kHz, where it gives much wider dispersion than a woofer can.

Tweeters don't hiss. Amps do.

It doesn't. But the extension should be ported as well in any event.

That's true of all speakers, and so long as they're less than 1/4 wavelength off the floor it still applies. I/4 wavelength is 86cm at 100Hz, 172cm at 50Hz. The same applies to the distance from the baffle to the wall behind the cab. This does bring up another point. If you have boom you can reduce it by lifting the cab high enough and/or pulling it away from the wall far enough. In effect you can utilize the cab height off the floor or distance to the rear wall as a notch filter. As to cabs being too bass heavy at gigs it's often for the same reason. You can have a combination of cab to ear to boundary distances that result in cancellations of the lows where you're standing. Move away and the distances are longer, cancellation frequencies shift downward to below the range of the bass, and magically it's louder and deeper ten meters away from the cab than it is at two meters. Just another tidbit that guitar players need not be concerned with, but bass players must.

Yes, but refrigerators tend to be between 38 and 40F, so as not to freeze anything. My mother told me when I was a baby our refrigerator, in winter anyway, was a peach basket perched on a stand outside the kitchen window. It's going to hit 50F here tomorrow, then back down to the 20s on Sunday. We're usually around 10 degrees higher than Toronto, 10 degrees lower than Boston. For sure OP keep an eye out for refrigeration. Commercial units are notorious for creating a mess of the AC, even when on different branch lines.

Probably rounding it up. That's OK, because nominal driver impedance ratings are just that, nominal, not exact.

You'll get the best result with another cab loaded with the exact same driver. Otherwise you're creating a chain with a weak link. Comb filtering has nothing to do with the driver sizes. It happens in the highs when drivers are placed side by side. Doing so also halves the horizontal dispersion in the mids compared to a single driver, or multiple drivers vertically stacked.

Three 16 ohm drivers would give 5.3 ohms, which is as low as one really needs. That's no problem with OEM, but at retail there aren't many 16 ohm drivers to be found.

Resistors won't work, they lose too much power and get too hot. 12 ohm voice coils aren't a problem for OEM, you just have to meet the minimum order requirement. With Eminence that's 50, although I can't see anyone order fewer than 100.

Oh, I always replied similarly when my wife said something. But I never actually heard what she said. It was just a defense mechanism against her repeating herself. 😉 I didn't notice where you were ordering it, so this advice is late, but this or something similar would do much better: https://www.sweetwater.com/store/detail/AmpStd--on-stage-stands-rs7000-tiltback-amp-stand

I'd think it's cold enough there to put much of it outside. Not frozen, of course, although I could have done that last week.

I wouldn't, since my 112 goes as loud as a '69 SVT 810 would. 😉 It's a form factor that we really haven't needed for some thirty years now, thanks to both driver technology and PA. It remains the staple backline rental cab, since you won't find anyone who can rightly say that it's inadequate.

It's certainly possible. How low or how high a driver will go isn't determined by its diameter.

When you have one speaker that's optimized for use in the lows and one that's optimized for use in the highs. Electric bass 410s and 215s are not. They're both full range.

I saw that, but separately powering isn't bi-amping. I said 'you may' as one amp may suffice, if the impedance load isn't too low,

That could make things worse. Ground loop noise intensity is increased as the length of the ground wire is increased. Worse, it varies by the square of the wire length. Doubling the wire increases noise by a factor of four.
