Subless setup - Peerless SLS 6.5

[SiW80]

Won’t be listening with engine off and don’t have time to fab a box, boot (trunk) build etc so wondered if a pair of SLS drivers up front in the passenger foot well or rear foot wells would give enough lower midbass / high sub bass for listening while driving.

What size sealed box do they need?

Anyone used these as a sub in a multiple array?

Other front speakers will be Alpine Type X 5.25” mids (biggest size I can easily fit in the doors) and Alpine SPX clone tweeters in pods on the dash or a pillars.

Cheers!

I would definitely go vented with this driver, as bass output would be nonexistent in sealed.

PE recommends 0.21 ft.^3 vented, for an F3 of 55 Hz. Not sure of corresponding tuning for that F3, but guessing ~50 Hz.

The 8" sls is a popular door midbass driver as they work well IB. The 6.5 would be better ported as grinder pointed out. If you dont want to build a box I recommend an IB subwoofer install, if you can make it work in your car.

Happy to do a small box up front but can’t use the doors.

A driver that's well suited to IB will typically need something on the large side. PE recommends 0.72 ft.^3.

Take more time to mod space in footwell than to throw a box in boot or just put some under seat

I had a lot of luck running the SLS6 IB in my door with significant midbass output. However I was high passing it at 70Hz. As you pointed out, if he could fit an SLS8 in the door that would be awesome for more low end extension.

3x the cost compared to the peerless for not much gain if you just need something for 500hz and under, the peerless are hard to beat for price and performance.

I have a similar interest...

I'm planning on using all four door locations for some strong midbass drivers, and would also think about ones that could extend down to 40 or even 30 hz if possible.
I want my sub box to be removable, and could have an alternative DSP setting that would remove the high pass filtering from the midbasses and turn off the sub channel.

I was hoping for a 6.5" that would be sufficient in a sealed setup as well (difficult to do that inside a door cavity - but at least easier to get sufficient space for a 6.5" than an 8"), but I suppose there's always the possibility of venting it just sideways into the door cavity to start with, or a passive radiator, and then working out some invisible way to create openings or a grille to let that energy in without letting all the road and wind noise in.
