DSP - worth trying?

Silly question alert:

The bias weight currently sits flush against the ‘lever’ - does this mean I’m currently at minimum bias? If so, I’ll try leaving it there and see how it all sounds.

Cheers

Left it as it is.

It’s fine.

You just can’t help some, erm, people ?

If you mean me, then yeah…

EDIT: with hindsight, I’d like to think that some of my posts in this thread make me appear more stupid than I actually am.

But in truth, I am pretty fucking stupid most of the time.

Your collective patience is appreciated.

Don’t these speakers have DSP already, perhaps I saw the wrong model, or you can’t change it?

What I would do with a standard pair of speakers is bypass the XOs.
The originals will be 2nd, 3rd or 4th order and cause horrible phase rotations around the crossovers.

Then multi amp;
a cheap Crown for the bass oomph, some silicon or tube amp for the mids and another for the treble.
Then use a decent DSP unit (miniDSP flex 8?)
Use only 1st order XOs (they cause only 90 degree phase rotation) and use PEQs to assist above the low pass, either side the band pass and below the high pass and control the phase rotation.
Protects the drivers at high SPL.
This way you avoid the usual phase F ups.
You can then use a few PEQs to smooth the SPL response to taste.
Time the drivers relative to each other so they work in unison maximising phase coherency.

A few PEQs to take care of room modes, job done.

A changing phase is a change in time.
You can’t hear phase rotation limited to 90°, or phase rotation below about 100Hz.

Perhaps other Zu models include DSP, but not the Definition 2.
Funnily enough, the guy I bought the Zus from threw in a Crown XLS-1500, which he had been using to power the bass units, as he said he had RFI issues relating to the built-in bass amp. He did tell me he’d been really impressed with the Crown and didn’t feel he was losing anything by using it over the integral amplification. I never had any RFI issues, so the Crown hasn’t even been out of the box since I acquired it.
Your post prompted a google, which suggests that the XLS-1500 includes some basic DSP functionality, which might be worth exploring further?

Thanks.

Yes, that’s the one.
It can’t do PEQ filters though.
Just brutal X/Os. I don’t use those on the LF (50 to 325Hz).
They’d be fine on the Subs though ( 20Hz - 60Hz).

You need the more expensive XTi range for PEQ facilities.

Take back control :joy:
