Crossover for this driver

I want to use this along with Aurum Cantus AC200/50C2Cand Aurum Cantus APR1.2 just need help with the crossoverwith these drivers. thank you
Asked by: gregory
You have a few options. First - both of these drivers are of audiophile grade - so you don't want to cheap out on the crossover. One: Stay in phase. If you want to do a simple 6db/octave crossover - plan on 4500hz for safety. There is enough headroom on both the woofer and tweeter to have a smooth transition at that frequency. You'll need an "L" pad for the tweeter or calculate resistors to reduce -3db to match the woofer. Use high voltage polypropelene caps on the tweeter and air coils of large gauge for the woofer (18ga is fine). Personally, I'd go with an L pad rated at 100 watts over the resistors for more headroom and the ability to tweak the sound in various environments from reflective to absorbtive. If you really want to go crazy-good - build a 24db/octave crossover and at 2500 hz. You'll get a more open sound by using more range on the tweeter. But the crossover is more complicated with more parts and can be pricey. Have fun!

how many cubes for 2 ported, with a tuning 50 hz?

Asked by: arntsmag
There are many variations and response curves available for these drivers. They work well in both sealed and ported enclosures. A 5" at 50 hz is good for a near-field or computer monitor - but not a large home theater setup - it would be better as a midrange... A box calculator will help you select your F3, determine the net box volume and the length and diameter of the port

Which one?

Hi,I need a midwoofer for a 6 inch wide .15 cu. ft. cabinet.Do you think the AC 120/50CK would work or would 2 TB 1720s be better.The lows are crossed over at 120 and the highs at 3k .Thanks Bob
Asked by: BobTrz
The Aurum Cantus AC-130F1 5-1/4" Woofer is a very good match for your small cabinet. It is a cutting edge product. While the TB's are very good - they are no match to an Aurum Cantus.
