Re: Subwoofers vs budget... where do you draw the line?
Hi j0nny,
A lot of sub plate amps have high-level inputs as well as the normal low-level RCA inputs that connect to an AVR's pre-outs. To use the high-level inputs just connect them in parallel to the same speaker wires as the main L/R speakers. Note un...

Re: Subwoofers vs budget... where do you draw the line?
What you need to do is connect to the preamp level outputs on your receiver. Sometimes those are used to connect equalizers and sound processors. The preamp level signal is sent to the subwoofer amp through a low-pass filter. Plate amps usually have l...

Re: Subwoofers vs budget... where do you draw the line?
No, sorry, I wish it were that simple. The LFE output can be used for distributed subs, but it can't be used for flanking subs.
Flanking subs need a low-passed version of the signal sent to the main speaker they're flanking. So you need to run the p...

Re: skywave's 3Pi subwoofer build
Wayne,
I finally found some Baltic birch in NYC. Very expensive, and I hope the shop can make straight cuts for me (they have a table saw, nothing fancier.)
Hoping not to bend your ear too much, I have a few questions.
The sub build is being done a...

Re: Flanking Subs vs Helper Woofers
You're right that home theater sound processors don't have any provisions that make flanking subs or distributed multisubs any easier. Honestly, the underlying philosophies and technologies most home theater processors are based on was developed before ...

Re: 3Pi Subwoofer
So 50W is sufficient for these subs.
I'm assuming then that something like this...

(500W Plate Amp)
would be complete overkill?
Thanks

Re: Pi7 Mid Horn Question's
Thanks Wayne, information very helpful. I looked at various other sites for store bought systems and 1 to 2KHz XO range seems too be a recurring theme these days. I will scrap the Sentry idea and present another scenario. I also have Altec 809-8A, (800Hz) ...

Line level or High level inputs for Subs w/ plate amps
Hi Wayne and all Pi lovers,
What is your preference when hooking up plate amps in subwoofers?
the options are long RCA cables with adding a Preamp output or Y cable, or just adding the extra shorter run of speaker cable from the plate amp to the main s...

Re: Stereo subwoofers a big success and a bonus
That's awesome, Bill. Glad to hear the plate amp wasn't broken and that all that was wrong was the Y connector. I'm with you on the double outputs on the preamps - it's a mandatory option for me these days. I've done the Y-cable thing too, but much pr...

Re: 3Pi Subwoofer
Yes, it's my PI-12 woofer, an OEM version of the LAB12 machined to fit the cooling plug. For the three Pi subs, you could use either driver just as well.
I'm using a pair of those Selectronic 50W Class-A FET amps. Plate amps work great too, and are ...
