Here is a topic I'd like opinions on as I'm thinking ahead to building new DIY subwoofers. I'm looking closely at a pair of Devastators. For those unfamiliar, these typically use high SPL 21 inch drivers in huge cabinets. One of the main purposes for this build is they peak around 130 dB in the "chest slam" frequencies. Gun shots, punches, etc..
When thinking through this, I'm starting to question how one would configure something like Dirac to maintain this chest slam outcome. If you set your curve to flat, then you would essentially attenuate out the slam. On one hand, one might have a goal for a flat response, but doesn't this method remove the whole intent of a subwoofer cabinet such as this? Sure, you'll still be moving a ton of air, but I feel like allowing Dirac to follow a flat or a Harmon curve would severely limit this type of build. It is my opinion that you would tailor the curve for the subwoofer to keep this intentional peak.
Thoughts or opinions?
What I am looking for is feedback regarding this scenario. What I am not looking for are opinions that suggest this isn't pleasing to the Sound Gods. Let's keep the discussion constrained to the intent of this particular subwoofer build and its purpose. ☺
Thanks in advance!
Interesting read, thank you for sharing as I too have toyed with the idea of building a sub-woofer. Although I was looking at the Fi audio HT1 and pairing with my crown CE1000 amp. ficaraudio.com/product/ht-1/
At any rate; your question on EQ and how it affects your output if done via Dirac. Could you bypass Dirac for just the subs and manually EQ them? I have not worked with Dirac nor your processor so I am unsure. If manual setting the sub/s are available I would think a full signal pass with a cutoff of around 200hz (or wherever you want to cut them off at) would give you what you want. Anything above 0 will boost the frequency anything below it will cut if off. Also a sealed box will tend to give you a bit more punch from my experience in car audio.
Again I am not a pro just talking it through, hope this helps and if not well.... Good luck
