Re: Mono "flanking sub"
I use a plate amp that is attached to the sub itself.
I tend to prefer it set at 50hZ, which many find too low.
I believe the crossover (low pass 50 to 100hZ)slope is 12db.
I use no eq.
I come from a mindset/point of view where, you try to fix the...

Re: Software for optimizing multi sub parameters
Where are your subs located in the room? What kind of subs are they? Is their anechoic amplitude response pretty flat? Is the SPL of each approximately the same?
I ask these things because I usually see smoother response as long as the subs aren't ...

Software for optimizing multi sub parameters
I'm finishing up on a project:
- Above modal region a waveguide (dayton 10inch) / 10inch woofer combination for controlled directivity
- 1st order cardiod radation in the transition zone by using a damped u frame
- multi sub (4) for the modal region (...

Re: Two 3 pi subs to replace my horn?
You've got mail!
Hornsubs are about 10dB louder than most direct radiating subs, sometimes even more. So it takes more power to get the same SPL, and even then, you really need more of them to prevent overtaxing them.
On the other hand, hornsubs h...

Re: Subwoofers are back in town
That's it Wayne, "subtle".
I thought I might be going overboard building four 15" sealed subs. My sub amp is switched with my processor, so it's easy to play music or video with the main amps off (and speakers silent).
The subs just r...

Re: Kind of crazy idea for a flanking sub processor
Just butting in here because I think I get what you guys are cooking up and I likey!
What about this idea: Come up with a circuit of some kind that will allow you to connect Left, Right, and CENTER. Then, when bass above 80hz pans hard left, it goes...

Re: Flanking Subs vs Helper Woofers, revisited
You can build what I would describe as a "detatched 2.5-way" speaker. Essentially it is a DI-matched two-way with a second midwoofer in a separate box, physically located as presecribed for flanking subs, i.e. just beside, behind and below the...

Flanking Subs vs Helper Woofers, revisited
Wayne,
I'm trying to think of cost-effective approaches to not only building multiple and flanking subs, but also have some serious output as well (for home theater).
It seems logical to me that one could build some subs that sacrifice low end fo...

Re: Flanking Subs vs Helper Woofers
I would agree (and expect) some differences in details, but I'm not sure how significant those details are. At least, less significant than the main idea, which is to use multiple sound sources spread apart spatially, and to use EQ, where appropriate fo...

Re: Flanking Subs vs Helper Woofers
Hi Wayne,
The situation regarding Harman and multiple subs has been somewhat confusing. The first multi-sub processor box they made that I'm aware of was the BassQ. As far as I can tell, it used FIR filters and a pretty sophisticated algorithm for com...
