How come 410's have more bottom end than 115 or 118?

    i've played through a number of rigs while i was at my teachers studio and at the music shop. i've noticed that in general, the 410's have a better low end than most 15's or 18's. i've played through an acoustic 301 through a 370 (350 watt head through an 18 reflex horn). it didn't sound floppy at all (big speakers = floppier, right?) but when i played through the same head and a peavey 410 (don't know the model), it had more bottom end. why? or is this too subjective a question?

    Well, the 18 might have been a good cab, that's why it wasn't floppy.

    The 410 might have had a lower freq. response, but it also probably has a much "tighter" bottom end that cuts so that's what you were hearing.

    Hope I was helpful, MP:)

    It depends a lot on how the cabinet is tuned. Even Eden's 410XLT has a lower reach than their 115s. Some say it's because of the fact that a 410 has about twice the speaker surface area of a 115. Others say it's a lie. I think they're all liars, and nobody really knows. Like Phogchris says, just go with your ears. Hear me now and believe me later.
  4. Porting plays a key role too in frequencie response as well.
  5. There has been a lot of discussion on this.
    All said above is true. There is a lot going also_One thing about 18s and 15s, especially folded horn design, is that the low frequencies that they produce so well, are not that appearent in on stage. They develope out on the dance floor and the back of the room. The 4-10 cabinets produce better "near field" low end, and seem to stay pretty even throughout the room.
    I do, however, have a 15 in a scoop cab that sounds great up close. It is a Musicman wth a 15 BW in it.
  6. Because the 15's and 18's are put into cabinets that are too small for them to develop maximum low end.

    I Have a Crate with 2 15's in it up close it sounds great but at a distance it doesnt sound as good

    I just wanted to tell you:eek:

    thanks! this clears things up quite a bit.
    i've heard the more surface area bit a lot, but i wasnt sure. i have a question for ROCKBOBMEL: is there any way you can control where and how the low frequency sounds are "projected" or is that all dependent on the way the cab is designed?

    Surface area has nothing to do with it, I assure you.

    i have to agree with ROCKBOBMEL on the acoustic 301. i've got an acoustic 301 powered with an acoustic 370 and all the literature i've read on it says that due to the folded horn design of the cabinet it takes at least 25-30 feet for the fundamentals to fully develop. i have yet to try this rig in an outdoor setting or even a large room, but i bet it would really rock. check out the reviews on harmony-central.

  11. It's because of a phenomenon called sound coupling. When you place 4 identical 10 inch drivers in a box and feed them an identical audio signal they respond like a single 40 inch speaker and a single 15 or 18 is no match for a 40 inch speaker.

    :D I don't think so, Mudbass!

  14. I'm not sure I understand your question about surface area. I hope this will answer the placement part.
    Like MikeyD stated in another thread. If you hang any speaker enclosure from the ceiling into the middle of the room, you get a stated amount of bass. Move it to the floor in the middle, and you double the bass response. Move the speaker to a wall in the middle, and you double that. Now move it to a corner on the floor, and you double it again.
    I read this once in a McIntosh catalog, and it had a good illustration on the doubling effect.

    Sorry I am not concerned with all the technical specifications...

    Yes - it's often inherent in the cabinet/speaker configuration (design of the cabinet and shape of an array of cabinets). As Bob said, placement relative to room boundaries also is an important factor. Regarding "throw" of bass, see the thread I started about a year ago at
