Blew my 12".....AGAIN!!!!!

That's the rig I was talking about. But a single 5" speaker would get blown to bits using real power, when compared to a single 15".

That's the exact same thing I usually say to myself, when people post the fallacies about speaker size not mattering...
It comes down to driver design. There's not many 5" drivers out there designed to go low. It's possible - massive, massive xmax and other T/s tweaking. But you lose a ton of efficiency. There's always a trade off involved.
And, that's just looking at the speaker. The enclosure is just as (or, arguably, more) important. Just take a listen to a 2x10 ported versus 2x10 sealed for instance.
Edit: Also, when that phrase ("speaker size doesn't matter"), it's plainly obvious that Talkbass members are talking about common bass cab speaker sizes - 10", 12", 15" and 18".

No single mid bass driver of any size can take 900 or 1500W - which is the power rating of the head the OP is blowing speakers with (bridged). It's a moot point in this case. More drivers or a smaller amp is what he needs.

Did they pay you extra for your bouncer services?
No, the bar usually shared tips with us (in addition to the venue pay). That night was much less than they usually took in with us performing
.I agree with every word. Especially about cabinet design.
Forcing a smaller driver to inefficiently drive down where a larger speaker can do it easily is a massive waste of time, energy and money.
here's another vote for the Eminence LF series. my favorite bass speakers. I have one in my Aguilar 1x12 and it is a MONSTER
Also, keep in mind while you limited your argument to 1:1, often times that's not what is used. Even a 2x10 can easily go lower than a ton of 1x15 and 1x18 cabs, and do so efficiently. There's not even that many 1x10 cabs out on the market.
For 1) I would use a crossover that sent anything less than 150Hz, not 100,000Hz. and for 2) I would put a low pass filter on there so nothing below 30Hz gets through.
Disagree. Give me 2 15" cabinets, and I will go lower, at a higher volume than 2 10" speakers because of the amount of air I can move.

I know it doesn't matter to you, but power handling and frequency response (just to pick a couple of parameters) are not identical. If you don't identify exactly WHICH drivers you are referring to, comparisons based on size alone represent a slender hope of grasping an illusive certainty, IMHO.
In other words, you can find any number of examples to support your view, but they all ignore the basic fact that there are plenty of good smaller bass drivers that kill plenty of crappy big bass drivers. Discuss.

That depends a lot on the 15" speakers. I have a couple Celest 15" guitar speakers around the garage that can't handle the "bass" from a skinny string with more than 30 watts each.
That is not a fact that can be stated. You can't paint with such a universal brush.
Which is the point - just because it's a 15" driver, does not mean that driver and enclosure is designed to "go low". There are 2x10s that will *still* go lower than 2 1x15 cabs. Take for instance the Acme Low B2 cab. That is tuned incredibly low. It'll go lower than say, 2 Ampeg PF-115s.
And I've seen 5" drivers that couldn't handle an AM radio.
There are crappy drivers made everyday. But, all things being equal, a larger driver can always go lower with more volume. It's based entirely on the ability to move air.
Get a 10" speaker with great excursion, and a 15" with e same excursion, and the 15" will go lower every single time.
That is based on cabinet design, and not speaker size. The two things are completely independent.
So? If I had to pick one up to go to this theoretical gig with zero FOH, I'll take the Acme, not the Ampeg. Lower, louder, lighter, more power handling.
The only thing the diameter of the speaker tells you, is the diameter of the speaker. Everything else is up to T/S parameters.
If you wish to continue this, I suggest a new thread or feel free to PM me. At this point, we're far off topic and not helping OP.
