Re: 2Pi's completed - now I want a center channel
Here is the current plan, build 2 Pi Towers for left and right. Reuse one of the current cabinets for the center channel. Shrink the screen size slightly, and make the screen frame 3" instead of 4". This will allow for a better looking soundst...

Re: Crossover Answer
That's right, exactly. Manipulation of the values (or the load) changes the transfer function and phase. You can slightly overdamp or underdamp the filter to provide a little bit of a peak or dip at the crossover frequency, and do other little adjustme...

Re: Under-Biasing Output Tubes
Remember that bias is used to bring an active component into its linear operating range. In a class A amp, it should be biased precisely at the center of its range, so the signal swing can move as far in the positive direction as it can in the negative ...

Re: Parametric Equalizer
Ouch, $500. And you say the $300 gave poor results. No, I don't want to adjust the base. Some fine adjustments in the mid and upper registers.

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: Parametric Equalizer
You will find them in pro audio equipment. Most have balanced or 1/4" inputs and outputs, so you would need to get some RCA/Balanced adapters. http://www.parts-express.com/wizards/searchResults.cfm?srchExt=CAT&srchCat=210

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 vs. Passive Crossovers
I agree with Wayne, any old active crossover will not cut it, that's why every thing's shifting to DSP x-overs rather than analog active x-overs. But using a properly designed passive x-over is a lot less expensive than going DSP and the cost of an extra a...

Re: Active vs. Passive Crossovers
Active crossovers are great, and offer several advantages. However, the problem is, just going active doesn't assure the DIYer of success. The crossover still has to be designed for the acoustic solution, which is not trivial. I see far too many DIYer...

Active vs. Passive Crossovers
At AVS forum DIY speakers, several people have made statements that they no longer use passive crossover networks. Instead they use active (electronic) crossovers.
First, can someone give me a short course for dummies in Active Crossovers?
Are they r...
