Re: Flanking Subs vs Helper Woofers
Wayne,
I totally buy the idea. I always wandered what can be done about the ugly notches right above subwoofer crossover point. With my faulty implementation of the flanking subs technique, I've seen the proof of how well additional sources in the reg...

Subwoofer Crossover
I am getting ready to upgrade my electronics (the 4 Pi speakers and modified Pi 3 flanking subs I built and documented here were the first step). To that end, I am suplementing my Onkyo TX-SR805 THX Ultra2 7.1 A/V Receiver by adding an Odyssey Audio Khart...

Re: Active vs. Passive Crossovers
You'll have to read through and around the marketing hype, but here's a summary of the functions an active DSP crossover performs. You'll need to read the intro section first, then click on the each sub heading (loudspeaker correction, room correction,...

Re: Active Sub Crossover
Well, this is a very good post. Distorted op amps give solid state a bad name. This is evident in most all receivers and amps that started using them in the late 70,s and early 80,s.
Changing out the op-amp Ic,s and the capacitors makes all the differen...

Re: Multi sub hook-up question
No, you'll want to low-pass the subs, meaning you'll need some kind of crossover. For flanking subs (nearest the mains), you can use a simple coil in series, but this will only work if the subs are as close to the same sensitivity as the mains (which is...

Re: subwoofer use for old cabinets
Don't high-pass the mains, let them run wide open. Low-pass the subs depending on their distance from the mains. If you only have a couple subs, make them flanking subs and low-pass them around 90Hz. Put the mains on stands, and put the subs on the floor...

Re: 1pi or 2pi for surrounds?
You might consider getting one of these:
Active Sub CrossoverSeems cheesy, but it really works great. If you are running a separate sub amp anyway, then this isn't much extra cost at all. And doing the mods is kinda fun too.
Just set the mains as &...

Re: 4 Pi and 3 Pi Subwoofer
My kits arrived. I need to get my act together with building the cabinets. I'm building them out of 3/4" mdf with cherry veneer to match the cherry surround on my Rega P5.
I'll be veneering some shelves (for a flexy-rack) first, but I'll still be v...

Re: Subwoofer hook-up
With a passive preamp, you pretty much have to use mains that have input adjustments in order to set the relative volume levels between mains and subs. This is true with active preamps too, if there is just one output. That's how I run mine - I have an...

Re: Subwoofer AMP
Certainly, that will work just fine. Tap into the preamp signal going to the amp for your mains, and run it to a sub crossover. I've tried several crossovers, and had good results, some better than others. Ironically, the one I like best for multisubs...
