Single 10" vs pair of 8"

Given the option of a single 10" D4 or a pair of 8" D2 subs with the same 300W mono either way, why would you go one way or the other? The pair of 8s has about 30% more cone area and 2mm less Xmax but 4 coils running off that 300W. Image Dynamics ID are the specific subs in question. Would your answer change if we were talking about Alpine Type R?

EDIT - only considering sealed enclosure due to space.

I hate sealed boxes. Never heard, or built one I liked..... Or used for more than a week.
But anyway, just curious, what kind of vehicle do you have, that you can't find room for a couple 8"s or a single 10" ported ? Both would be relatively small enclosures.
I have a single 8" in the back of my Prius, in a ported enclosure, and I think it was only .6 cubes net ? You could do away with the port volume too, if you used a passive radiator.

PS, if you want more, nicer sounding bass, and truly can't make enough cubes of space for the sub(s), can you cut a hole somewhere ? True Infinite Baffle setups use next to no cabin space, and can make BIG bass, on minimal power ☺

I'm running a huge 5 cu ft net enclosure for my 18" sub right now, and it sounds great ! But my next setup will be true IB setup, with a 24" Stereo Integrity sub. It will take far less space than my 18" sub does now.

Jaguar F-type coupe. It's got just enough room in the trunk for a weekend trip but does have a storage compartment under the floor that I'm willing to sacrifice. I haven't actually determined how much space I can manage out of it but pretty sure it will be 1cuft max and likely more in the .6-.8 range.

I've only ever had sealed enclosures (except for a big compound box with 15" back in college) and I'm happy with that in general. My other car currently has a 10" IDQV3 sealed getting 400W and that's sufficient. I have JBL GTO804 that I just built a little .3 shoebox for as a tester. Still need to install my amp so can't try it out yet but that will give me a starting point for reference. I at least have room for a single 10" though.

Came here to look for a sub for an F-Type convertible. I've seen the under seat prefabs recommended but I'm wanting more. I'll grab some popcorn
I'm not familiar with the specifics of the convertible trunk aside from knowing it's small. Do you have the additional storage tub compartment under the floor where the battery and relays are? I haven't done measurements yet but it should accommodate a decent sealed 10". A bit of fiberglass work would maximize the available space but not sure if it's necessary.

I know that this thread is over a year old, but I was curious as to what you guys ended up doing for upgrades in your F-Types. After doing a full system with an aftermarket HU and an MS8 in my LR3, I kept telling myself that I was done with the whole car audio thing since it's so difficult to work with modern systems, and the audio systems in my last two Audis and in my wife's BMW X3 were halfway decent. However, my F-Type R's "Meridian 770w Surround System" is absolutely atrocious; It's on par with the factory system in my 1988 RX-7, and I swear that it's actually WORSE than the 1992 Escort GT I had in high school! I treated the doors and hatch area, replaced the factory tweeters with the Dayton AMTPOD-4s, the mids with Faital Pros, and added my old JL MicroSub from my S5. It now sounds pretty good for podcasts and audiobooks, but music is still pretty much painful to listen to. So it looks like I'm going down the rabbit hole again.

Interested in your insights and experiences.
