On a TV screen connected to the sub or with the Plus series on a connected PC, you can see the current frequency response and make your adjustments. You immediately see the effect of your adjustments. You can not only move the bands (parametric) but you can also adjust the slope of each filter. This way you can make adjustments for smaller or wider areas.

The Digital Drive series also offers Auto-EQ, but this feature never really convinced me. And since it is so easy and convenient to do it manually, there really is no need for the Auto-EQ, IMHO.

Velodyne also offers the parametric EQ in a separate product, which is the SMS-1. I think it is in the same product category as the device that Kal mentioned.

Cheers!

Yes, they are in the same category, nominally, but I have had consistently better results from the AM Dual-Core than from the SMS-1. I agree with you about using the Velodynes in the Auto-EQ mode because it uses only the fixed default frequencies and does not take advantage of the ability to vary frequency which the manual mode permits. OTOH, the AM Dual-Core works very well in auto mode and has more controllable variables.

I do not use EQ with the Bryston SP3. I connected the Velodyhe SMS-1, but aside from the fact I may not have been using it correctly, I thought it compromised the sound in a way that I cannot articulate. Perhaps my room is sonically perfect which I sincerely doubt. But, I like the SP3 without room correction.

I wish the SP3 had room correction. The argument against it having room correction sounds hollow to me. Let the owner engage room correction if he/she wants to, but let owners have a choice. I am sure that most folks do NOT have a perfect room.

Thanks to all that responded regarding my question on an EQ for my subwoofer. What really has my interest at this point is using Dirac along with my laptop. I have read reviews which claim it is superior to what Audyssey does.


I guess I need to invest some time and educate myself on how to set-up a Dirac system and how to use it to EQ my sub.


Thanks again,
David
