So i have recently added some Hertz 6.5" mille pros, they are really good with real good clear crisp sounds, now that ive sorted out the crossovers



What ive noticed is that that the mid bass thump from the 6.5" does not correspond with the subwoofer bass thump



Theres like a minimal 1 or 2ms delay, like the 6.5" Hertz millie pros hits the bass then the subwoofer hits afterwards



You cant notice it with the bass on high volumes but its there



My previous head on my VW had a subwoofer delay option, im currently using a factory head on an Audi A5 B&O set up



I cant change the head because it covers everything else in the car



Any suggestions?
 
It’s a function of delay indeed, a DSP is the best solution but you could try switching the phase of the subwoofer amplifier to see if that helps.

If it doesn’t try pointing the subwoofer in different directions in the trunk until you find a combination of phase and direction that sounds best.

I find positioning a sub near the rear of the trunk and pointing it away from the driver is a good starting point in most saloons.

thanks would you say that fitting a dsp is an easy job for a amateur? like someone with basic experience? it seems the DSP is connected between the RCA leads and amplifiers?

Yeah, DSP is easy and effective. It’s changed everything for car audio for those reasons.

The Dayton audio dsp408 is cheap and works well in my experience.

how comes its only the Americans that only sell this device, Dayton audio dsp408

its not available in the uk ebay or amazon or any uk retailers, where did you get your from?

thanks matey

I got mine from the ‘States as I have family that live out there and visit us a few times a year.

Soundimports.de knock them out for around £150 I think, Buying a Dayton Audio DSP-408 DSP module? | SoundImports - SoundImports

If I wanted another one I’d be tempted just to order from the parts express shop on eBay and pay the import taxes, lots of options.

i see

ive done some research but not finding the info on install

If i got this can i simply connect the input with rca input from my rca tapped from my loc

then connect output rca to my amplifiers?
