two 210s or 210 and a 115

I'm not sure how you can say a 1x15 cab and a 2x10 cab are each "full range" I guess that that's the break in communication. A cab with 2x18 with 2x10, some 2x5 and then some tweeter/horns would be "full range" Also, I'm not sure how the lows that a 2x10 can't get to that the 1x15 can are not going to be affected because it is still 8 ohm instead of 4ohm. Unless it's an amp that doesn't double it's power into 4 ohms from 8ohm rating. Impedance is frequency dependent.

If you hooked up, in parallel, a 12" 8ohm driver and an 8ohm tweeter you will not get a 4 ohm load. But if you hook up, in parallel, 2 12" 8 ohm drivers and 2 8ohm tweeter, you'd get a 4 ohm load.

I've built a few speakers. So I'm cool with how speaker impedance works in relation to frequency reproduction. ;)

Yet at the same time, unless you're crossing over your 10's from your 15's or you've got an active crossover running, a lot of your example doesn't make much sense.

Specifically, almost ALL production cabs with 10" drivers are full range cabs and almost all cabs with 15" speakers are full range. Very few cabs with multiple drivers (unless designed as two or three way speakers) have individual speakers that are not running full range (A couple that do are Accugroove and Acme).

The tweets that are in these cabs usually have a very crude high pass at best, rather than something that crosses over with the woofer, and has a frequency range/sensitivity that doesn't cover the same territory anyway (usually even leaving a big hole in your tone in between tweeter and woofer as collateral damage).

*edited to add that your understanding of how frequency and nominal impedance work in relationship to 10's and 15's isn't correct, and yes, liable to cause damage. If we're talking about what a properly crossed over mid or tweeter presents to an amplifier that's one thing, but not to general mix and match cabinets.

Wouldn't a 15 speaker give a little bit of a fuller low sound than 10 inch speaker. I equate it to plucking an open A string or fretting the E string at the 5th fret. Same note (A), same octave, but they do have a different "sound". So in the realm of cabs I could see the benefit of paring the 10's with a single 15". That is a pretty common stack configuration anyway. Using the 115 to give a nice deep sound while the 410 (or 210) provides the punch and clarity. Keep in mind this is only a layman's view, I am not a sound technician in any way shape or form, it just seems to make sense that way.

that's what you call "engineering by looks." the 15 looks bigger so you think it will go lower. yet, i've never heard a cab with 15"s go lower than the ampeg svt 410hlf, so that pretty much puts the kibosh on engineering by looks.

I'm kinda in the same situation myself. I have a 15/6 LDS cab that I love....and I want to add either a 15 sub cab or 1 2x10 cab.

If I ensure the impedance is the same for 2x10 as my current 15/6...I figure things should be fine.

But a big ol' 15 stuffed under my 15/6 sure does sound like some serious meat.

i would add the 3015lf cab. that mid cone should give you all the mids and low highs you need.

Every time someone ponders a mis-matched cab above or beneath a 15/6, God destroys a vintage SVT. ;)

Get a 15 Sub. You won't regret it, AND it will sound better out in the room since you've got matched drivers. And trust me, with a 15/6+15/sub rig, they WILL hear it out in the room.

Then help me understand the prevalance of the 115 paired with the 210 or 410 cab configuration. It seems to be a very popular bass rig. If the different size speakers don't do anything different then what's the point. I am very intersted right now because I am wanting to upgrade from an Ampeg 115 combo to a head and cab setup and can't decide between a 410, a 115 and a 210, or a 115 and a 408.

bass players are not rocket scientists, by and large. and somewhere along the line, a couple famous bassists who weren't rocket scientists got the idea that a 410/115 was a best of both worlds thing, and manufacturers played into it. next thing you know, lots of people are doing it.

And it keeps on happening because virtually noone compares 2 rigs side by side at gig volume in the same venue by listening to the mix from out in the crowd and walking around.
