I personally have an PSB subwoofer, which I really dig for the money. There are a ton of options though. What's your budget?
Infinity Primus C25 for the centerDescription: Two-way, reflex-loaded, magnetically shielded, stand-mounted loudspeaker. Drive-units: ¾" "Metal Matrix"-dome tweeter, 5¼" "Metal Matrix"-cone woofer. Crossover frequency: 3.3kHz. Crossover slopes: 24dB/octave. Frequency response: 58Hz-20kHz, ±3dB. Sensitivity: 88dB/2.83V/m. Nominal impedance: 8 ohms. Recommended amplification: 10-100W.
Infinity Primus 360 x 2 for fronts
Thanks. :wavey:Description: Three-way, reflex-loaded, floorstanding loudspeaker. Drive-units: ¾" (19mm) MMD tweeter, 4" (100mm) MMD-cone midrange unit, two 6½" (165mm) MMD-cone woofers. Crossover frequencies: 350Hz, 3.3kHz. Crossover slopes: 24dB/octave. Frequency response: 38Hz–20kHz, ±3dB. Sensitivity: 93dB/2.83V/m. Nominal impedance: 8 ohms. Recommended amplification: 10–200W.
All of your crossover settings will be done in your Onkyo, I imagine.
Save the lecture, Teech. I know what a crossover is.What do you mean by that?
The Infinity Primus 360’s don’t have separate driver terminals so they cant be bi-amped. They have an internal fixed cross over.
What a cross over does is split the spectrum of sound coming from the amp like a prism separates light. The highs get sent to the tweeters the midrange gets sent to the mid range speakers and the low frequencies get sent to the woofers. The roll-off curve defines how and where the mid range speaker gradually stops working and the woofer takes over. The smoother this transition happens the more accurate the reproduction of sound.
When you are using mains that have a low frequency driver it is important to have your separate sub unit conform to the same roll-off curve. If you don’t the woofers in the mains and the subs will be working agenst each other for all but a tiny bit of the frequency range they cover.
Its like this… On a tandem bike both peddlers need to pedals at the same rpm’s if one is slower, then the faster one is wasting energy to make the other one go faster. Besides loosing energy the sound will be muddy. Like when you us a 10 inch and a 12 inch together in the same car.
:rofl:...lmao oh my badWe're talking about home stereo systems, not car audio.![]()
Save the lecture, Teech. I know what a crossover is.
I meant exactly what I wrote. The Onyko, his receiver (obviously somewhat current, if it's a 7.1) will have internal settings for what frequencies go where. He'll choose "Subwoofer crossover: 80hz" in his receiver setup more than likely. He'll probably also choose what size his mains are, thereby choosing their crossover point as well.
