Dale-
funny thing, i'm the post who asked you about your behringer with 1.4 software, never heard back except you're checking. Reason it's funny is it for my two rythmik F12's.

Has there been any reviews of the FV12? I am looking for a MUSICAL sub that would be at home in a Condo with 5 KEF LS-50 speakers. I am concerned over too much bottom disturbing the adjoining condo units so I would prefer the LF not to go down as low as the FV15.

The FV12 is long gone, since replaced by the LV12R.

The above graphs are open plane testing; ideal conditions. What I want to know, how well will a pair of them perform in a room our size?

...11Hz.

If one buy's a pair of FV15HPs and gets them "properly" dialed in (based on REW measurements) you won't have regrets.
(dial in a pair of FV15HPs......and you'll understand what the word "spoiled" means)

*To Chucka:
Use a high pass? IF you're worried about too much extension there's your answer... From experience you want a subwoofer capable of playing much louder/lower than you need such that listening at normal -> loud volume is just as effortless, i.e. low distortion. People that complain about too much bottom end usually could use more bass traps/eq, it may not apply to you but I'd look down that road if you haven't already.

Complaining about too much bottom end?
...
I've read of folks complaining about not enough bottom end, but never of there being too much bottom end. What am I not understanding?
...
Have these folks who are complaining, used room measuring software to measure and graph the acoustics of their room? Are these same said people using "quality" room correction software to correct for the acoustics in their room?
Are these same folks trying to make magic with a single subwoofer based subwoofer system?

Perhaps what he was trying to say is the bass is too boomy? That's just a guess but I agree, I want more bottom end as do most people. However if it's port chuffing then I could see someone wanting to back off a bit. That could lead someone to say too much bottom end I suppose.Complaining about too much bottom end? ...

Agreeing with you, in my opinion, that would that be an excellent reason to buy a second subwoofer?
We had boomy with our system but it was boomy because I had the gain on the subwoofer turned up to high. I don't like boomy so I turned the gain back down. I solved all our problems by purchasing a pair of FV15HPs, a XT32/SubEQ HT equipped AVR and installed and got a freeware copy of REW up and running to be able to measure and tweak the settings.
I state the above only because it's a thread about FV15HPs.

Very happy with the pair of FV15HPs and you went DIY FTW-21s?

Now thass a lotta air being moved. We have 3300^3 open to kitchen and other areas and can feel the breeze coming across the floor.
What's it like when you're cranking your system?

Oh I just ordered them early this week. Won't be in til next week at the earliest. My space is huge hence the reason I went with 2 FTW-21's. I'm at near 7500cu ft for the great room area which is family room and kitchen and completely open. I'll let you know how it all sounds in a few weeks when it's all complete.

That's some exciting stuff. Hope the box assembly goes without troubles. I'd have to go to a cabinet shop to get the box assembled. Are you going with a 4^3 or 6^3 box?
Thass a big room to have to light up. At 7500^3, are two FTW-21s going be enough? I'd guess you'd need three, maybe even four to fill a room the way folks like us want.

Maybe a pair of Gjallarhorns?The cabinets will be around 7.5 cu ft maybe a tad bigger. I'm hoping they'll be enough but if not, two more it is
But that is only .01% of the room volume... Isn't the rule of thumb ~1%The cabinets will be around 7.5 cu ft maybe a tad bigger. I'm hoping they'll be enough but if not, two more it is
Seriously though, looking forward to your pursuits. I thought my space was large at 5000 cubes open to the remainder of the house... I guess not!

Cabinet size would be a little too big. Haha! I think dual 21's will be enough for me. I could place my most recent build, dual 10", near field to have a little extra mid bass if I need it but I doubt that will be necessary. If you look at at data-bass.com you'll see the UXL-18 and the FTW is basically the same motor and voice coil assembly. Just the cone is different. I'll have them in a bigger box then they tested the UXL in so look to upwards of 4-6db difference as that's what I got with WinISD. Having duals adds another 6db to the output I believe from what I've read regarding subs. So output would be as follows.....
10hz- 104.2db
12.5- 108.2
16- 114.1db
20- 120db
25- 125.1db
30+- 130db +
Of course these are 2m ground plane measurements outdoors. Just imagine what it'll be in room! These numbers also follow closely to what I modeled in WinISD. Pretty close to a Gjallarhorn's output in the 25hz and below area and putting out more in the 30hz and above.
