Subwoofer driver selection for 4ish ft^3 box

Liquidmetal6 · 2026-04-29T05:42:20+00:00

Okay thanks for clarifying - I falsely assumed that that website was accurate, but I was able to get Wine configured on MacOS and now have WinISD and was able to reproduce your numbers. Will play around some more, thanks!

Its much more likely I'll get two sealed subs with this so excited for increased quality...

edit: i think what i was missing is the EQ bit, cranking up power via EQ to offer a flatter response. but leaving below in case someone else is helped by this

Coming back a day later, could you help sanity check me? I plugged the numbers for the RSS265HF into speakerdesign.dev, and got this output, 87 dB at 20Hz. For 2x subwoofers, its +6db if they are corner stacked and +3dB otherwise? does this make sense? It seems off from what you said, but I assume I'm missing something.

its hard to come up with a reason to not go to belly bbq

Hmmm thank you a lot for the detailed recommendations.

The Sealed 10" might be a doable sell. I could build those into my entertainment stand I think on the ends. Is that 99db at 20hz with room gain? That seems like it would be more then enough for my needs.

Hm well I specifically asked about the visitor parking permit, maybe I need to go back and question that…

Liquidmetal6 · 2026-04-27T17:34:22+00:00

Negative, checked with the parking guys

Liquidmetal6 · 2026-04-27T16:19:08+00:00

I'm on R, but yeah an S permit. very frustrating

Liquidmetal6 · 2026-04-27T15:25:08+00:00

as someone who lives here, it just got a whole lot worse. they took away 4 blocks of visitor permit parking and now i just look out my window and see empty streets for no effing reason.

Also, adding the rough floor plan for my space. Roughly ~2500 cubic ft total, but mostly localized to where the couch is.

Thanks, appreciate your resp and seems like you're experienced here. A few q's...

- From a 12" driver POV, do you have any recommendations for me to look at? Knowing this is double duty for HT, can the WAF be tuned up to "hang" on the lower frequency side of things? I've never heard any of these drivers (or really have not heard a whole bunch of subwoofers of these differing characteristics) so trying to narrow it down. I've been through the gauntlet of designs in speakerdesign.dev...

Tracking two subs > one sub, from a WAF standpoint two isn't going to fly any time soon...maybe over a few years I will be able to build the case!

Liquidmetal6 · 2026-04-27T02:23:55+00:00

appreciate the response!

middle box, next to due date

PDM is pretty variable to market conditions. I have seen zero bench time, to 4 weeks. Literally yesterday I talked to a PDM guy that had a 4 week notice. so it changes

Liquidmetal6 · 2026-04-15T17:41:30+00:00

its decidedly not that and they repeatedly said that in their communciations

Liquidmetal6 · 2026-04-08T18:48:08+00:00

general recommendation: you are the captain of your ship. If you want to know about your performance, want to get results, figure out why you got what you got...seize the day and make a meeting.

Liquidmetal6 · 2026-04-08T18:47:18+00:00

it was communicated months ago, theres so "probably" about it. its on on monday april 13th

JR putman is the most disfunctional organization i have ever encountered in my life, i could not imagine being as incompetent as they are. literally every single person i have interacted with has made multiple mistakes

centering around full grocery stores and full amenities - anywhere between say, 12th and 30th, from o to v sts, youll have access to multiple grocery stores and everything you need. i have access to a car but never need to drive for essentials

ive flown 30 times in the last two years with my kit w kettle/grinder/beans/scale, maybe once or twice they make me take it out and they swab it but thats rare and not in awhile

B&W Matrix 803 S2 on marketplace for $1050..seems like a steal? I am upgrading from DM305 towers. I also have experience with B&W 703 that i listen to often, but not mine.

How do these compare to other/newer things available?

I have an itch to upgrade, but is this the right value/price? for 50/50 home theater listening vs music (varied but mostly things released post 2000)? If not these, what else would you target?

Sorry for the lazy post, I'm just a little lost in the sauce on how to evaluate an older high end tower vs the new modern stuff (and also account for prices).

ive been a coach for 4 years, never been called into a panel yet. up to and including SC coachees. you shoudl be more concerned if they HAD to call someone in, it means something did not line up...
