Want more midbass?

I run a rather ridiculous sub stage so I needed more mid-bass to keep up with(or try to) the subs. I'm running HAT L8SE's in the doors similar to the OP's Dynaudio's. I run 2 different sub stages during the year due to traveling for my kids sports. I run a sealed 13W7 which played up to 80hz well and was far easier to tune and drive when running 2-way with 6.5". However with my dual 15's ported tuned at 29/30hz would roll off 10-15 numbers below 80Hz. I initially added a 3.5" driver so I could play the 6.5 lower 70-75Hz without it also being required to run up to the tweeter x-over point. While it sounded okay I didn't get the impact I was hoping to achieve and doubling up on the wattage pushed the driver to hard. The 8" drivers however sound amazing and integrate far better with the 15's and perfectly mate with the sealed 13.5" sub.

From my experience any deadening/dampening applied to our vehicles helps in multiple areas.

Hey OP where did you install your mids and tweeters? What wattage are you running to your 3-way?

I started with the Dynaudio 8" in the doors, 3" dome and 1" Dynaudio tweeter at the top of the dash. But because the 3" did not go down low enough for me, I changed the 3" to a focal 4" mid and 1" tweeters with the Focal 3-way passive crossover. I had to cut out the dash and heat/bent the AC vents under the dash panel to get the 4" to fit. I ran this 3-way with a JL audio 300/2 and had a single 10" JL sub ran off a 500/1. This along with about 100lbs of sound damping material made this truck one of the best sounding/ staging vehicles I have put together. Here is a photo with the original dash speakers before I changed them to the focals.

Great idea. I haven’t thought to place the mids and tweeter on the dash. Currently my setup is stacked in the door panels. The imaging is good but I’ve been thinking about relocating the L3SE’s in the sails with tweeters in the factory Bose location. The doors I cut up are from an Escalade so I have the old ones in storage. The sails could be difficult to execute well. Especially since I use fiberglass one every 10 years. Might have to go the dash route now.
I also used about 100lbs of deadening materials along with 40’ of aluminum L-bar and gallon of panel bond.
I have a tendency to go heavy on the sub stage.
I do love the mid-bass response of the 8” in the doors vs the 6.5” I started with. Have you thought about sealing up the large opening on the door behind the panel? I used plexi(because I had it) then sealed up with deadening. It seemed to isolate the rear wave more and helped provide more punch. I am running 300 watts to each 8” so I could feel airflow around the bottom of the door prior. Now there’s far less and mostly around the glass. Thanks for the info.

I hadn’t thought about sealing up that hole but can certainly see how that would benefit; maybe I’ll do that on my next one which I’ll be starting soon. Speaking of 8” mid bass, look what I just won yesterday

I have edited my original post because the way it was worded was a little unclear. I am providing a template for others to use to put 8's in the doors.
