Question about mixing component speakers

Please excuse any incorrect terminology I may use, I am by no means an audio enthusiast.

My runner has the Focal ISTOY690 kit installed in the front. This is a component system with 6x9s in the door and tweeters in the dash.

I was thinking of replacing the tweeters with Infinity Reference REF-3032CFX 3.5" coax to fill in the mid-range some more.


I'd like to make sure the frequency ranges are handled properly. Looking at photos of the Focals, it looks like there's a capacitor glued to the 6x9s. I was thinking could give it the snip snip to bypass it.

The Infinity 3.5's come with a capcitor in the box, I was thinking of soldering this in-line just before the speaker connection.

Does this seem like a good approach?

Thanks in advance.

 

What makes you assume the Focal set was engineered to have a hole in the spectrum? I’m not big on Focal but I also don’t think the speakers are your issue.

 

I was thinking a 3.5" coax (which to me looks like a 3.5 speaker with a tweeter in the centre) would have better sound than a standalone tweeter. The idea was since the 6x9's being down by the floor, I thought having something more than a tweeter in the dash would be a good thing.

 

Really all you are doing is moving the same sound you already have around a little bit. It’s not going to sound remarkably different in my experience.

I had wide band speakers in the dash for a while, crossed over at around 300Hz. I’ve since changed that up, installing tweeters that are crossed at around 3200 and I don’t have an issue with midrange lacking or sounding like it’s at my feet.

I’ve run both ways passive and active and there was decent coverage of the full spectrum both ways. The sound stage was similarly high as well. I will say that I wasn’t satisfied using the factory radio as a source until I added a lot of correction and processing to it. If that’s what you are using I’d recommend looking into more power and a DSP so you have some control over the spectrum because the factory controls are not adequate, and what is there doesn’t address its weaknesses.

 

I see what you mean about moving the same around around. For the price that I paid, I'm convinced Focal did their homework when engineering the set. Thanks for helping me understand the concepts!

I'm using the original head unit and have some extra power going to the speakers by a Alpine KTP-445U 4-channel amp. I'll look into DSPs and different head units.

 

If you already have an amplifier you can get significant benefit by adding a FiX between the factory radio and that. The output on the FiX gives you a 10 band per channel EQ and the input correction makes the factory radio sound much better.

I have this on my factory radio and it sounds much better.

 

Im going to look into the JL Audio Fix 82 some more. Thanks for the guidance and suggestion

 

Depending on your needs/wants, you might want the 86. The 82 only has a L/R pair of outputs. I mainly chose the 82 for the digital out. I’m just using the analog L/R out for a full range subwoofer signal into the Epicenter. The 86 has your conventional 6 channels of output.

 

You're fine. If you run a 4 channel amp, you can adjust gain on front and rear speakers independently so you can match outputs pretty easily.
