HOW TO CONNECT SUBS WITH DXR15

[gsc1ugs]

I'm goin to get some subs probably dsx12 so my question please is this, do i use thru connection or link out at the bottom of the dxr15 cab? would i also leave the settings to FOH and HPF to off

Thanks in advance

If you are using DXS15 subs then, yes, use the 'thru' for the tops. Turn the HPF to 'on' so that you aren't wasting energy on frequencies that the subs handle. I would probably set the FOH to 'on' as well as there is a slight top end lift. But that will be a personal preference thing so try it and see which you prefer.

12” Subs with 15” tops?

I’d suggest the other way around. Replace your DXR15s with 10s or 12s and get a single DXS15 sub for the time being. I had that exact setup (DXR12s over a single DXS15 sub) a couple of years ago and I would say that nothing new in that price range could beat it. It was quite a powerful, and great sounding compact rig.

[Sam Spoons]

Yup, putting a 12" sub (or two) under a 15" speaker is far from optimum, you may get a little more headroom from the tops but probably no more bass than without. I use 2 QSC K12s over a single EV15" sub and it works very well. Two DXS12's a DXS18 do not make.......

[gsc1ugs]

i have sell my dxr15’s? Can a 18” sub work?i love these 15’s

[Sam Spoons]

An 18" sub will give you more extension and free up a little extra headroom in the tops. If you like em then keep em, they are good speakers

[gsc1ugs]

Anyone know a good 18 sub? size is an issue so smaller better

[Sam Spoons]

All the name manufacturers make decent 18" subs, compare cost, max SPL and size, they won't vary much on size. A quick glance suggests the JBL EON 618S might be a contender https://www.thomann.de/gb/jbl_eon_618_s.htm but go and see if there's anything on a deal at your local shop.

[gsc1ugs]

So consensus is the dxs12 sub wont improve anything?

[Sam Spoons]

Yup.

[MarkPAman]

If you want a consensus, then:

Yup.

I have DXR12s. When I’ve tried pairing them up with small (12” ) subs, or even bigger subs that weren’t up to it power wise, I’ve thought - why have we bothered?!!

The matching subs for the DXR15s are the DXS18s. There are other subs that would also do the job but they will be as big, as heavy and of a similar price to the Yamahas. Have a look at the specs and see if this is something that you could store, transport and set up.

[gsc1ugs]

Thxs for that will have a look. I hoped technology had got better but i suppose thats just top end, i believe to push air size does matter

[Sam Spoons]

Correct, as Scotty would say "ye canna beat the laws o physics Cap'n"

[gsc1ugs]

Why is this cab over a grand??? Dxs18

[Sam Spoons]

'Cos it's good. It's considerably louder than the cheaper ones, probably sounds better too. It's also very heavy though.

FWIW this one is €3500 and is passive/un-powered https://www.jsfrance.com/en/caissons-de-basses-actifs-passifs/11603-l-acoustics-renfort-de-grave-passif-sb18-version-2-neuf-2100000126361.html

Is a sub not just a thump downstairs? i cant understand why something is this expensive even that passive link you sent

[Sam Spoons]

Being pragmatic, in most places I play the sub is just producing some extra thump but, even then some sound much more musical than others. Cheap subs usually sound very 'one note'.

What is this?

Equipped with: 1x 18" Ferrit Woofer

[MarkPAman]

Something like this I think????



(Sorry)

Which speaker? Ferrite refers to the magnet.

[Hugh Robjohns]

As Sam says, cheap subs tend to be very one-notey, so they thump loudly but everything sounds the same and the bass doesn't play tunes. They also generate a lot of harmonic distortion which tramples all over the sound the top units are putting out, making the system sound harsher and nastier than without the sub in place!

A good powerful sub is inherently an expensive thing, and you do get what you pay for.

[gsc1ugs]

so the dxs15 is not good enough also, is one enough or do i need two? i'm doing a few mecca bingo places tribute

[Music Wolf]

If you are doing bigger venues then the usual suggestion is to hire for the first couple to;

a) get a feel for what is needed
b) limit the spend until you know what you need and have sufficient bigger bookings to make it financially viable.

If these bigger venues aren’t paying enough to cover the hire cost then either you are not charging enough or you are only getting the gigs because you are cheap.
