Acoustic Control Corporation 126 combo. The distortion may be the driver being pushed too hard, causing it to exceed it's mechanical limit. It also could be a sign that the driver is damaged.

It could mean the degree of attenuation, though that would be unconventional to say the least.

I'm hip, but the result on those stages will be the same no matter where the port is placed.

The port location doesn't matter. Dispersion of sound waves from ports, and from the cones as well below roughly 250Hz, is omnidirectional.

If I was Canadian I'd be looking at Traynor/Yorkville.

I would but that's out of my range for a weekend trip, which is as long as I can be away from home. If you haven't hit the Comedy or Jazz festivals in Montreal you need to add those to your list.

It's not just the area, it's the roads. In GB you can hardly drive more than 10 miles between roads. In most of Canada you can drive 100 miles between intersections, if there are roads at all. Nunavit province is mostly islands that can only be reached by boat or airplane. At 800,000 square miles it alone is ten times the size of Great Britain, yet has a population less than 40,000.

It's not bad, certainly no worse than any major American city, better than New York. When I get there the car stays parked, I either walk or take the Metro.

Big to say the least, but 90% of the population of Canada lives within 100 miles of the US border. Montreal is only a five hour drive from me; I visit there pretty much every summer. Another hour north and you're in the middle of nowhere. For the most part it's miles and miles of nothing but miles and miles.

+1. Some 90% of GB can be driven to from any other place in GB within ten hours. Some 95% of Canada cannot be driven to within ten hours from any other place in Canada. The province of Ontario alone is five times the size of Great Britain.

It would, the reason being that with the BGH-25-8 and the crossover I designed it works down to 2kHz, so you avoid the beaming issue with the woofers. The BGH25-8 also rolls off above 10kHz, where there's no useful content for electric bass. A 3.5kHz tweeter crossover makes perfect sense in a hi-fi speaker with a 6.5 or 8 inch woofer, but not in an electric bass cab.

BTW, if I was to go to the trouble of replacing the tweeter it wouldn't be with either the Peavey or Eminence APT-80. Neither go low enough to reach where the tens are beaming. This thread explains:

I found that, but it's next to worthless. You need a real data sheet, like this: https://eminence.com/collections/eminence-tweeters/products/apt_80#specifications

I can't find any real data on the Peavey Triflex to compare it with the APT-80. I found replacement diaphragms for the APT on Amazon and eBay, but that's the US sites.

It might look cool doing that, but the unplugged 115 will become a passive bass trap. 😲

Periodic cleaning of the jacks is a good idea.

Even at the top tier of touring sound I'd say 90% of FOH engineers don't know how to mix the bass. Most of those who do are also bass players and/or recording engineers.

Yes, I was. Even at 'only' seven pages there's a lot of different topics in this thread. Someone who might have an interest in one of them has to wade through a lot of information he doesn't care about to find what he's after. If this thread gets much longer it's going to need a table of contents.

Yep. What those not in the business don't realize is that both amps and speakers spend a lot of time being Beta tested before they hit the shelves. It's done so that it sounds good out of the box with as little EQ adjustment as possible. The manufacturer of one speaker that I designed took close to a year of Beta testing with dozens of players just to dial in the crossover. 😲 It was worth it, it won numerous new speaker of the year awards, but still that's a lot of testing. Using an FRFR you usually end up using a lot more EQ to get the sound you're after, which means it's not going to be a simple plug and play unless you have an modeling amp or accessory speaker emulating circuit. Think about that. You have an FRFR speaker and then you need an amp or accessory to make it sound like a speaker that's not FRFR. 🤥

For the cleanest sound set the output at full, the gain as high as necessary for the desired level.

Agreed, specific questions should be posted in individual threads, just as in the amps & cabs section.

True. But while the on-axis response of the 410 may be better the off-axis response of the 115 is better. Dispersion is inversely proportional to the width of the radiating surface, and you get comb filtering from a 410, you don't from a 115. Not only is mixing a 115 and 410 not a good idea, the 410 format is not a good idea. With the capabilities of today's ten inch drivers there's no question that even for high volume applications a pair of 210s vertically stacked is the modern benchmark.

Don't sell the PA. There will be times you can rent it out, with you at the helm of course. That puts money in your pocket, and gives you the opportunity to hone your PA skills hearing what it sounds like out front.

That's quite likely if his amp is too big. A smaller amp. 50 watts into one twelve is sufficient.

Insist that his amp be on a tilt back stand that aims the speakers at his head. If there's going to be suffering from his volume let him be the first to experience it. As for the ear plugs, if they're not buds to hear the monitor mix he's playing too loud. The backline should only be pushing the stage volume, not the room. They should all be in the FOH, bass included. High pass the bass and keys, if any, so the only thing in the FOH from them is the higher directional frequencies that need to be there for even distribution across the room. Also try aiming your lower cab towards the drummer, so he can hear your mids.
