Peaking on high frequency

[Deto1992 5]

I started a thread recently in which I got some good advice about specs for new box. I was told that I needed to build a new box with a higher tuning(37-39 hz) to accomodate my AQ driver. After building the new box, the driver has become irritatingly peaky. It hits a 45 hz note very well but drops off significantly on lower notes (30-32 hz). What can I do to eliminate, or atleast decrease, the peak?

How have you determined at what frequency it does what?

Tune lower like your previous box or decide on your goals. You cant have a high tuned box with great low end presence, its a give and take thing.

Not so accurately haha. I have simply guessed based on what I hear and have heard from test tones. I could be a few hz off obviously but the peak is more than noticable.

yeah I understand. Hopefully Kevin at Skar wouldnt mind taking this driver off my hands so I can see how the new VVX-12s sound. Hopefully I will be able to achieve the low end output that was lacking with the AQ.

I know the issue already, not enough port area.

EXACTLY!

it has nothing to do with the driver, it has everything to do with the box and user. if your refferring to the HDC and trying to compare it to the SKAR? hahahaha your kidding right?

maybe the SDC? which is what i hope you have.

when accomidation port area with high tuning, you simply cant plug something into a calculator and decide whatever port width you want.

it takes real math and real tuning. those subs are not meant to play that low, and in a box tuned to the 40hz range, they will never see the motor force at those frequencies.

if you want lows tune low. if you want highs tune high. theres a very hard middle ground.

As long as the design is there it can be very musical.

Friend of mine had a 4 15" walled F-150 with DD 9515"s. Box was tuned at 42Hz with 400^2 port for 20 cubes. It played down into the low 30's with no issues and peaked at 46Hz.

@ chris the man

May I ask where you see a comparison? You dont, because there isnt one. I can bring up two drivers in a post without comparing them. I was simply saying that I am not satisfied with the HDC3s performance (yes, the hdc3, I do know which driver I own) and taking advantage of skars trade in program may be a good idea. Before you act like Im completely ignorant, read twice so you will better understand what I am trying to say.
