I'm in the process of getting some HD15's and loading them with Fane Sovereign 15-400 LF, as the specs mostly match what should go into one of these boxes.

Now for my question.A reputable person told me that I will most likely damage/destroy my drivers by only using a crossover,and not a DSP.

Bare with me,he told me that I should high pass my HD's to 50hz.I'm still sort of new,only operated smaller systems before,and never used an x-over.Is it not in the capabilities of a crossover to high pass my bins?The person also mentioned something about the HD's needing EQ correction points.I'm sorry if I'm not making this clear,translating technical terms is a total bitch.

If I do, indeed need a DSP, is there a workaround?Like getting maybe an equalizer and crossover?

Sorry if this seems a tad bit incoherent, not being able to understand is extremely frustrating.

By cross over you mean active not passive rite?... if so a crossover will be "ok" but you really want something you can set delays with to get a better result. You wont destroy them but you also wont get the best sound you can out of them. A crossover is a good start and a cheapy like the berry 3400 has a delay function so you will get a better result then mst crossovers.

If you mean passive crossover... then dont both building HD at all. Lol
If it sounds like a gorilla is trying to escape, turn it down.

So,I should pick up and active cross over first.As I understand it, this will enable me to set the frequencies to where they need to be.

Aside from an active crossover what should my next purchase be?

Thanks

But,wait,why would I need delays?I'm going to be stacking 4 HD's,eventually 6 with a pair of good tops.From what I can gather you would use a delay in case of different types of subs.

Finally something that makes sense in the last 48h.
Don't have one.I'm open to suggestions.Guess I'm getting one with delay.
Anything else I would need for the system to sound proper?

you can't set any decent highpass on a simple active crossover. All of them have no highpass or a25 Hz highpass.

It's stupid to use something like that on a horn.

You'll blow the speakers on your first event.

And a DSP can do that safely,I presume?
Also,when you said EQ correction points,did you mean the delays?

To recap, I would need to do the following things to get the sound right and not destroy my drivers:
-Delay
-50hz Highpass
-Coupling the horn mouths properly

Did I miss anything?

....and then phone the person you bought them from and try to get them replaced under warranty claiming you only ever used them at half power at a christening.

(I'm not joking either.... this has happened)

+1 on the dsp, you'll get much more out of your speakers, you'll have your delay, your x-over and eq all in one. What will you be using your system for?

Don't get it eventally, get it now!

No proper lms with highpass is a recepy for tears and a lot of shredded drivers. Borrow one for the time being, don't waste your money on an active crossover!
