Just in case you forgot.....15's RULE

Discussion in 'Amps and Cabs [BG]' started by Lowactnsatsfctn, Jul 1, 2012.

Do 15's RULE for bigger Gigs?

Poll closed Jul 16, 2012.
  1. Yes they RULE! Everyone knows that

  2. I use something else, but know they Rule!

  3. I disagree ( please explain)

  4. Carrots are the best veggies for metal

  1. When you get down to the Basics, 15's RULE

    1.) They push more air than smaller versions of the same model.
    2.) They are cost effective when you consider a small up charge from a 10" or 12" driver. While it takes 2 of the smaller drivers for the same results. (2-12) is more cone space, but twice the cost

    Yeah, they're pretty much okay. :)

    I ordered a 1x15" cab friday and should have it next week.
    But I like all kinds of speakers, from 8" to 18" (and even Phil Jones 5"). It really depends on the cab itself.

    Last I checked, an Eminence Kappalite 3015LF cost a few dollars LESS than a 3012LF...just one more good reason :)

    With or without roadies?

    Good 15s are good, but there are some really horrible 15s out there. If a 15 is cheap it often ends up much more muddy than another size (in my experience this is the case anyway). But my point of view may be skewed a bit by the fact that the amp I use primarily (school supplied, wouldn't touch it if I could avoid it) is a Behringer Ultrabass BXL3000.

    410's move more air without being flabby but . . .

    I sure do have mighty GAS for a fEARful 15/6 and the Hard Truckers HT215B.

    I prefer 12's, but each to their own :)

    Not to beat a dead horse, but speaker size doesn't have much if anything to do with the way they sound...cabinet design, crossovers...well, lots of stuff but I have cabs loaded with 12's that sound EXACTLY the same as the ones loaded with 15's...the 15's just go louder, as a rule

    There's a lot more to the sound / tone / depth or whatever you're looking for than just the size of the drivers. Recently I was using a GK 115 Combo, but found that when I added a borrowed SWR 2x10 I got a much smoother / deeper bass response. Head to head, the SWR was better for what I wanted.
    Mindful of the smaller gigs we're playing these days I'm using a Hartke 112 Hydrive. It's fine but if I push it too hard it does become a bit raspy and the low end suffers a little bit.

    I have always been a fan of 15's.. One day I will be running another showman 1x15 (for big stages) to have an amazing room filling big tone that only two 15's can give.

    One thing I have noticed with 10's vs 15's is that the low end on a good 15's sound much more natural and open compared to a 10..

    I'm pretty happy with my fEARful 1212/6/1 or 12/6 depending on needs of the gig. Before fEARful, I used an 810e or 410HLN in the same roles. My last 15 loaded cab was an Acoustic 406.
  12. 15s Rule!!! :D

    EDIT: Someone once asked -
    If speaker size does not affect tone, why do they exist?

    Because some larger speakers move more air, handle more power, have better venting and etc. For example - just because an 8” woofer may be able to cover the same freq.‘s as a 15” woofer doesn’t mean it can do it at the same volume level (SPL) as a good 15" woofer - that’s the reason why there are no high power sub woofers the size of a dime.

    This is what Eminence engineers say ~

    Generally speaking, the number one contributor to a transducer&#8217;s power rating is its ability to release thermal energy. This is affected by several design choices, but most notably voice coil size, magnet size, venting, and the adhesives used in voice coil construction. Larger coil and magnet sizes provide more area for heat to dissipate, while venting allows thermal energy to escape and cooler air to enter the motor structure. Equally important is the ability of the voice coil to handle thermal energy. Eminence is renowned for its use of proprietary adhesives and components that maximize the voice coil&#8217;s ability to handle extreme temperatures. Mechanical factors must also be considered when determining power handling. A transducer might be able to handle 1,000W from a thermal perspective, but would fail long before that level was reached from a mechanical issue such as the coil hitting the back plate, the coil coming out of the gap, the cone buckling from too much outward movement, or the spider bottoming on the top plate. The most common cause of such a failure would be asking the speaker to produce more low frequencies than it could mechanically produce at the rated power. Be sure to consider the suggested usable frequency range and the Xlim parameter in conjunction with the power rating to avoid such failures. <snip>

    Generally - speaker size also matters when it comes to moving air (SPL) - cone area.

    How to calculate cone area.
    Cone area = pi x (r x r)
    pi = 3.14 r = radius of sub

    # 8&#8221; 10&#8221; 12&#8221; 15&#8221; 18&#8221;
    1 50 78 113 176 254
    2 100 157 226 353 508
    3 150 235 339 530 763
    4 201 314 452 706 1017
    5 251 392 565 883 1272
    6 301 471 678 1060 1526
    7 351 549 791 1236 1781
    8 402 628 904 1413 2035
    NOTE: All numbers rounded down to the nearest inch.

    Drivers, enclosures, power, etc all are factors - and speaker size does matter when it comes to moving air (SPL), etc and shouldn&#8217;t be downplayed. And remember the cab is built around the driver and not the other way around.
  13. Orange OBC115 is one example of why 15s are great.

    I've played some good 15's but my musicman hd212 does everything the 15's can do and probably sound more punchy and clear.

    They also have poorer dispersion than a smaller speaker. Just sayin. IMO marrying yourself to a specific speaker size is just silly, find a cabinet that you like and go with that, regardless of what size speakers it has in it.

    That said, I currently use two 115's.

    A 15" by itself....nada. Never heard one that had a nice tight punchy sound with lows that are not muddy. I like to be able to actually hear the notes. Not just feel them!

    I switched over to 10"s back in 1988 (my first was a Trace Elliot 4x10) and have not looked back!

    Now a 15" cabinet coupled with a 4x10 (even a 2x12), that is a whole other story. You can get some killer sounds from that!

    I'm probably the black sheep here, but I stopped using cabs, for the most part, at gigs anymore. I have a 2x10 on stage, but usually just some volume for a mic.

    I don't see the point of big and bulky cabs on stage that throw stupid volume. That's what P.A.'s are for, and my in-ears give me more than enough bass. Just look at Dream Theater and Rush....
  19. If someone has to explain why that general statement is wrong, chances are you will not be willing to learn why ;)
  20. True - good post, and I agree - however when the 15 crushes the 10 we hear how little dispersion actually really matters in the real world. ;)
