Looking for subwoofer placement recommendations

[Evolvd]

Let me first preface this buy saying I’m reasonable intelligent with audio builds but not in the S550 chassis.
That being said, I’m looking for input from those who’ve tested or swapped their subs facing into the cabin vs facing into the trunk.
Im sure many of you are running one way or the other, I’m only looking for feedback on what noticeable sound differences you’ve heard if you tried both in the S550 before settling with one direction and why.
My plan is to do a custom fab permanent sub box and would prefer not to waste the time and material trying to figure which direction sounds better.
Thanks!

You're asking a question that can be subjective. I've had my subs facing to the rear and am satisfied. I admit, I never tried facing my subs forward. There are plenty of people that have them facing forward and also satisfied. Do you have any audio shops nearby where you may be able to get opinions or possibly see and hear some installs?

As a semi professional musician for 40 + years, for bass frequencies orientation does not matter. The size of the driver does.

No offense to your experience but orientation can make a significant dB difference. This has been proven time and again and there’s plenty of evidence posted to YouTube to back it.

Unfortunately the quality of audio shops around my local area is limited to box and speaker installs, very little to no custom fabrication work. Not that it matters as I doubt any of them would be willing to let me “borrow” their gear only to give them no business afterwards. I am more than capable of fabricating my own test equipment, but as I said in the original post I’d rather not waste the time and material if the experience of what I’m asking for is in this forum. My apologies if that was not expressed properly.

If it is out of phase, you are correct.

Exactly. Without expensive mics and measuring equipment I have very little way of seeing if my sub placement is allowing the wave to propagate or if it’s causing standing phase issues. Obviously with bass frequencies it’s not likely I’ll run into any significant wave cancellations, but that’s the whole point of this post…to find out if anyone has done the testing or measurement.

Place the woofer where it fits, get a dB meter and swap the wires. Radio shack made an inexpensive one, many professional bands use them to comply with sound regs.

What a lot of these morons don't know is you may be 100dB in the car and 130 60 feet away.

Except that I’m doing a custom fit wall which will be permanently affixed to the car. Turning it around won’t fit right, hence not wanting to waste the material and time just to “figure it out” on my own. I feel like I’ve said this a few times now. Yes there are multiple ways to skin this cat, but the fastest and cheapest is to see if anyone else has done it….not to sequester opinions on what I “should do”.

 

[K4fxd]

Since it is a "custom fit wall" you need to do the experiments.


Personally I hope you shake the car apart.

It seems it's most important to get the spacers in the rear seat back cushion so the bass transmits to the cabin through the gap, otherwise it's just trapped in the trunk.
.

I don’t use my back seat so they’d be in the down position when I’m cranking it up.

Might be some cheaper ones......

Ok, I’m trying not to be rude here but it seems the point isn’t getting across. Im NOT looking for recommendations for where to mount my subs. Im asking if anyone has tried front firing against rear firing and what their opinion between the two is. Thank you.

 

[Cathul]

If you do front firing make sure you seal your trunk to the cabin.

You might be better off asking this on a dedicated audio forum where people have figured out the best way to mount subwoofers in an S550.
