I got a whole pile of 15" car audio type subs I have to offload next.
Anything that would be better than two JL 10W6v3 D4's sealed, 1kW @ 1 ohm? Perhaps 1 sealed 15" can take up less space than a rectangular sealed dual 10" box in the trunk.

What was it you were looking to improve most with your setup? Are you mostly listening to music or HT or maybe gaming?
It's mostly movies / TV shows. But I do listen to music as well, and I'd like to get closer to the chest thump from bass guitars and kick drums. Hopefully this is a step in the right direction!

That makes sense. I just placed an order for the HTM-10's - a bit more cone area, and a step up without going bananas in terms of size. I'll report back in a few weeks once I've got them assembled and dialed in.

SME, that is a good point. I know even less about mains than I do about subwoofers. The HTM-10 kit from DYISG is not too large and might be something to look into - I don't know if there's anything else on the market that would be equivalent.

Hi,
I am doing a bit of research and trying to figure out what if any gains I can get from say 16...18Hz - 80Hz by moving away from the dual Ultimax 18" flat packs (build thread here @ AVS). MiniDSP 2x4HD is used, and the receiver is setup with no subwoofer (integration, xover etc. done with the DSP). The mains are the HSU Research bookshelves powered by a Behringer NU1000DSP. The room, which is shared with the kitchen, is approximately 7ft8in tall, 23ft deep and 20ft5in wide, for a volume of roughly 3600 cu ft / 102 cu m.
I do not think a ported design is possible due to the limitations of the external dimensions. The flat packs are 23" H x 20" W x 20.75" D, or 5.52 cu ft, and I can go up to 25" H x 21" W x 21.75" D, or 6.6 cu ft.
First, I was looking at building new ported boxes for the current subs, but I cannot find designs that fit within 6.6 cu ft externally. PRs also get expensive, but it might be worth it (around $900 shipped for 4x). I was eyeing the SI SHS-24 which is on sale right now, but the cabinet just cannot be made small enough. So, I think I have to stick with 21" drivers. The IPALs would not be a great fit for sealed enclosures I believe, so I would have to look for other 21's.
Am I on the right track here? Using multiple smaller (potentially ported) drivers would also be an option perhaps, but stepping down in overall area doesn't seem to be that efficient.
Edit: To give you an idea of what the room looks like, this is the living room, picture taken from the kitchen.

That might be enough for a small apartment, or so.
Jesus.
How much time is spent on time aligning all those speakers and ensuring a "great" sound stage?

Reading through this thread has been really inspiring. I discovered new drivers that I would consider reference (IPAL and its brothers), and learned more about horn enclosures.
It makes me want to attempt building a small horn loaded subwoofer for use with desktop speakers and the such, just for its high efficiency.

Usable port velocity with large ports?
in Bass Projects

Hi all,
After having enjoyed my dual sealed 24"'s from Harbottle Audio for about a year now, I am toying with the idea of building ported boxes for them. For example;
I would have to add a flare (40mm / 1.6" radius or so) to the ports. It appears the max port velocity in this setup would be ~30m/s which for 6" ports does NOT work according to https://www.subwoofer-builder.com/port-flares.htm :
My thoughts are:
Am I on the right track? Thank you
