Ampeg is mixing cabs!

Well, it appears that the Ampeg rep doesn't want to have anything to do with this:
"This subject is a well-worn road and you’re trying to find answers that don’t exist.
The answers do exist. Either the responder doesn't know what they are or he'd rather not admit it, because they don't fit the company marketing goals.
As for Ampeg bashing, I don't see it that way. Every company that markets the 1x15/4x10 combination is equally guilty. Ampeg is by no means alone in denying inconvenient truths.
 
Adding mush before the room gets hold of it is surely a daft thing to do.
Not that I disagree with this entirely, but I've heard plenty of mixed rigs carrying the room that weren't mushy. Me, I don't like the sound of the vast majority of mixed rigs I've played, and I do see the point you're trying to make, but to say that it guarantees mush is just as daft.

Ever hear of something called "freedom of choice"? Tell you what...when Ampeg reps spot you at the store and force you to buy a 410/115 rig with a gun to your head, then you'll have a legit complaint. As of yet, I've heard of no company ever doing that to potential customers, even that bad old Ampeg.
 
I always find it odd when I read posts where people are arguing with manufacturers that their product "wasn't designed that way" or that it works differently than the person who designed says it does. Learning requires the willingness to listen and being ready to admit that there are things you didn't actually understand as well as you thought.

If I were a manufacturer/designer, I'd find some of the feedback and attitude to be a disincentive to continuing my participation on a frequent basis. I'm very thankful for those subject matter experts and industry thought leaders who choose to continue to hang out, share their insights, and basically provide us a free education.

And that's why Bill Fitzmaurice and Greenboy no longer grace these pages.

Not really. Bill left because TB brass requested he be less condescending in his replies and he didn't want to. I liked Bill myself, but he does get a kick out of being condescending. I don't think I'm letting any cats out of the bag there. It's pretty true about Greenboy, though...he left because he was sick of being hammered by anti-fEarful types who accused him of forming a cult and sending this cult out across TB to force people into buying his cabs.

I stand corrected... somewhat. I remember reading some of Bill's posts/threads where folks pretty much said he didn't know what he was talking about. After a while that takes it's toll. Ah well, the more things change, the more they stay the same.

It's pretty much the same thing for all teachers. There comes a point where you get so fed up with students arguing with you that your options are to either become the object of a school massacre headline or to walk away. It doesn't help when the school administration isn't in your corner.

Not according to Bill.

I am sure that's Bill's interpretation of it, but I was there when it happened and actively posting on the thread that ended it for him. Sure, some people attacked him, but that's what you get for having such rigid and unbending beliefs. Bill's scientific knowledge about how cabs work is stellar, but he could be incredibly impatient with people who tried to get him to further clarify his statements or disregarded the science in favor of their own tastes. And he didn't differentiate between them and the people who were deliberately yanking his chain just to piss him off.
 
Yes, it is a loss. They could be pretty contentious at times but were a font of knowledge that's now lost here on TB. I'm sure there are others who gave up and went home too.
My entire professional life has been spent with extreme type A personality military operators and alike, as well as with some of the most brilliant scientists and engineers in the world...make no mistake here, I was pretty much parking cars and serving drinks in that crowd, but that was still the crowd I traveled with.

If you can get past the occasional lack of political correctness or nurturing attitude/approach in the interpersonal communications skills area (yes, I'm being kind in my characterization), you can learn a ton of stuff that most people wouldn't even know is something to ask about.

If you want to engage with the greatest minds and thought leaders, you really have to toughen up a bit - its not personal. While not everyone in that league is lacking in the social graces, most are driven in ways that they don't have the time or patience to be slowed down/annoyed with arguments and ideas that they feel should have been well understood before you walked in the door. They will gladly teach, but only if you will listen and your questions are an obvious respectful quest for deeper understanding and not a personal challenge.

Swallowing my pride to travel with these kind of folks has always been worth it to me. YMMV, and it's most certainly likely to vary a lot for those who tend to somewhat disrespectfully challenge everyone and everything, but aren't packing the intellectual gear or experience to carry the day.

Of particular interest is an explanation of...wait for it...why 1x15/4x10 usually isn't a good idea, along with supporting data that the Ampeg guy says doesn't exist.

As an engineer (albeit not in this field) I can't think of one good reason why this approach should work well in general. However, I leave open the possibility that with the right drivers, cab designs, and crossovers all matched to be complementary, such a set-up (in one or multiple boxes) could work for some. While I do not personally care for the voicing, size or weight, Mesa has a 410/115 cab all built into a single box (PH1000) that many like.

Right. Ampeg is pure evil. They hate you and they want you to be so dissatisfied with any purchases we make from them that you return them and cost them lots of money eating the returns.

It's patently obvious that you will never settle for anything other than a blanket apology and refunds to everyone who ever bought a mixed cab setup from Ampeg since the 70's. So I'm checking out of this aspect of the conversation, but hey, far be it from me to tell you to stop your search for the justice you seek.

No less of authorities on the subject than Greenboy and Bill themselves have both stated that it's entirely possible to have mixed cab rigs with similar phase relationships that have no ill effects on the sound. Greenboy used to recommend using a 12/6/1 with a 15/6/1 all the time. Still does, too. Hell, Bill used to recommend installing two Jensen Mod 10-50-32's in the 810e's of the mud era (2000-06) to brighten them up! Andy said that when he was working at Genz Benz that they would use speakers with similar phase relationships in their cabs of a given line for this very reason. So did the engineers at Ampeg I've talked to. So the idea that this isn't a consideration is a construct in the minds of those with an agenda. I don't dig the mixed cab rigs, either, but let's not pretend that every company just slaps whatever speakers they can get for cheap in a box.

EDIT Not saying you're saying that. Those I'm speaking to, know who I'm speaking to :D

Point well made Jimmy and you're right, I'm neither an Ampeg hater (quite the opposite actually) nor a "no mixed cabs ever" zealot. The current Mesa Subway line, which I am very familiar with, actually benefits from mixing cabs not only IME, but in the experience of many others according to their representations on TB. I also know that Hartke designed their 115XL and 210XL cabs to be used as a set - a buddy has them and they sound great when he plays them and I enjoy playing on them as well. I could go on, but I think the point is clear.

I tend to agree that any two random cabs in combination, especially from different manufacturers, like say a 115 and 410 or a 610 and 112, are likely going to be a crap-shoot for a great number of technical reasons, but it could work out well. As an engineer my only general caution is to not assume that because say a Subway 112 and 115 or 210 and 115 sound great together, we now have empirical evidence supporting a position that any 210/115 or 112/115 combination will sound good together. In fact we can't even readily assume that any 115, 112 or 210 will sound good on its own. ;)

Right...as they say, the results are unpredictable in those cases, and there's only one way to find out. Personally, I still think it's the safe way to go under any circumstances, but I had to let go of the notion that most people want to do anything more than plug in and play some bass!

Absolutely! And here's a thought that many of the "right or wrong, no maybe's crowd" rarely seem to consider (at least when I read their posts): It's entirely possible that two random cabs manufactured decades apart by two different companies might actually sound better to someone or an audience than two cabs manufactured on the same day, by the same company, in the same factory, which were designed from day one to be 100% complementary.

Physics can be funny like that!
