Will 2 x TS212S give the same deep bass as 1 x TS218S?

I would like the deep bass accosiated with an 18" sub like the TS218S, but this speaker weighs 32 Kg and we would like a lighter setup that dosn't break the back of those who have to carry it. The TS212S only weighs 20 Kg.

Would 2 x TS212S produce the same deep bass as 1 x TS218S ?
Or would it be better to by 1 x TS215S?
(We will have this setup on each side)

According to the specs TS218S and TS215S both goes down to 35 Hz, where as TS212S only goes down to 42 Hz.

  • Hello,

    Thanks for posting. 

    No, the sub will not produce the same amount of deep bass that you're looking for as the TS218S. This is because the TS218S has a frequency response of 35–95 Hz, whereas the TS212S has a frequency response of 42–100 Hz. If you're looking to add deep bass to your sound, it may be better to use the TS218S.

    In fact I would go one bit further and have two TS218S subs as your never going to have a rich bass otherwise, a friend of mine has four TS215S and with a bit of tailoring the bass is reasonable but depending on what your using this set up for, I don't want to disappoint you but in my opinion the TS212 only has a 12" driver and to be honest good for very small rooms with a mid to high range effect, any cabs sporting a 12" driver are good for 'foldback' or monitors and if you want them for your main PA you gotta stack them on top of some subs I'm afraid. Keeps you fit.
    Here is what I use 21" sub, 18" sub/bass, twin 10" mids, & twin HF horns per side. running 4 way active, sounds nice.

  • @Phil, our events usually have around 100-150 guests. Your setup seems to aim at a larger venue.
    Anny way I dropped the idea of using TS212S.
    I'm still considering the TS215S. And of course two of them. One on each side. :)

  • The specs for both TS218S and TS215S says 35-95 Hz. So would TS215S have the same deep bass sound as the TS218S, just with 2 db lower max SPL?

    The whole idea of having a larger cone is that it will normally be more efficient in developing a lower frequency albeit maybe only 10 to 20 hz lower than a 15" cone but 30 to 50 Hz lower than a 12" cone at the same SPL (sound pressure level) yes there are many 8" or 10" drivers that can reach lower frequencies in tuned cabinets designed for HiFi with much lower SPL where you will need 4 or 6 cabinets to equal one properly designed PA cabinet using a 15" driver mainly because it moves more air. but for a 150 guests which is a reasonable crowd (if they are all up dancing) I would always want a bit of headroom not wanting to red light the amps all night, funny thing is I had a larger system back in the 80's and we used this for the same numbers as yourself but never really cracked it up to full volume, but it was a quality hifi sound with plenty of headroom.

    But I would say that if your concerned about the weight issue then go for the TS15's against 18's as most people wouldn't notice the difference as they came there to have a good time. The photo was taken on a film camera in 1980 of my older setup.

  • We might have to do with the TS215S for now, since the guy who has to transport the gear is pushing hard to get the weight down.

  • Using the TS215S should be fine but tell him that lugging round your kit is good for exercise, lol.
