Just wanted to get a general idea of how many subwoofers most people have in their home theater.

 

[pbz06]

Are we counting living/family/entertainment rooms too? Or just separate dedicated theater rooms with rows of seating?

I'm the former, and only have one (HSU VTF15-MK2). One day I'll have an actual theater with 4 subs

Yes, I am referring to your "main" home theater whether it is a living/family/entertainment room setup or a separate dedicated theater room with multiple rows. If you have a living/family/entertainment room home theater and and separate dedicated theater room, vote based on how many subwoofers you have in your dedicated room. Basically, vote based on the "best" setup you have.

3...

2 subs w/dual 18'' drivers and 1 mbm with one 12''

 

[subacabra]

Two PSA s3601's in main setup
One Rythmik lv12r in bedroom
One Dayton 8 in sons room

16 subwoofer drivers (8in) in 2 in-floor subwoofers enclosures;

Next build: x32 (10in) subwoofer drivers in 8 enclosures in 2 line arrays.

Smaller driver (10in) = better control; All driver enclosures are sealed.

I didn’t see “Not Enough” listed as an option...

 

[ratbuddy]

Smaller driver (10in) = better control

Maybe do a little more research on that, it's a myth..

 

[Will P]

I can't remember the last time when someone noted that 18in subwoofer was more musical than a 10in subwoofer..

 

[Will P]

Every time the subwoofer size is increased or the driver motor design is modified to provide "High Output" that reduces the cone control. That reduces the "musicality" of the subwoofer, it's ability to blend in with the speakers.

All you have to do is take a closer look at the Impedance and Phase graphs around Fs.

The harder it is for the driver motor to control the cone the more uneven the graphs appear.

Below are the Impedance/ Phase graphs for some Dayton Audio Reference 10in, 10in HO, 15in, 15in HO and 18in HO subwoofer drivers.

The larger driver has to move much less for the same excursion as a smaller driver since the SD is so much more. Smaller drivers do not sound better, a properly designed subwoofer sounds better, no matter the size.

 

[Will P]

For the same SPL one has to use multiple smaller subwoofers to match the Vd , not just the Sd of a bigger sub.

The penalty for more musical subwoofer is the increased price of the multiple subwoofers. It's usually x3 more expensive to use multiple smaller subs to match the Vd of a much bigger subwoofer.

That's the nature of audio - for any gain there is a penalty.

I'm not one of those Floyd Toole cultists, but excuse me if I believe him over you on this one. Again, smaller = more musical/faster/more control is complete myth.

edit: And if you can blindly tell whether you are listening to a trio of 10s or a single 18 with both in properly designed systems, I will happily eat a shoe.

If you know how many you have.............then you don't have enough! Just sayin.

Subwoofer cone control is a well known issue.
It is audible too if you haven't heard it (pun intended)

Cone control issues are the ONLY reason why servo subs exist. The servo system tries to mitigate the cone movement erratic behavior after that deviation gets registered by the subwoofer servo amplifier.

Servos are a holdover from a time when woofer suspensions weren't as good as they are today. With apologies to Rythmik, they aren't really needed anymore.

Yes, not everybody can justify the higher price. Most people opt out of buying a servo subwoofer and with the savings they get a soundbar

BTW.. Rythmik G25HP Direct Servo subwoofer (Dual opposed 15" sealed audiophile sub with 1800WRMS amplifier) has been reviewed by Jim Wilson on December 29, 2018 from the AVS forum and is currently being rewarded with AVS 2018 Top Choice Award.

C'mon, now you're just trolling. Noone said Rythmik makes bad subs, just that servo tech is not needed with modern drivers. Go do some homework and you will see some of your ideas on subwoofers are mistaken. Don't just stick your head in the sand and assume you know everything.

Sorry to OP for derailing so much, that's all from me

 

[Will P]

Why so defensive? Those are facts..

4 total for me.

2 - Dayton Audio RSS460HO-4 18" in custom Marty enclosures handle 12Hz-50Hz duties and 2 - BIC 12" Acoustech behind the couch for nearfield 50 Hz-80Hz.
