Re: How to HFD five Hypex FA502 plate amp (for active subwoofer only)

Can someone tell me what does the capacitor and resister (???) Between the two drivers?

How does it affect or improve the sounds?

TIA

Re: How to HFD five Hypex FA502 plate amp (for active subwoofer only)

I was lazy to pull out the gear for measurement. However, I listened to sweep from 20Hz to 300Hz, very pleased with the result! The lowpass for the upper sub were between 80Hz and 120Hz, three presets. Highpass at 45Hz. The lowpass for the lower sub was 45Hz too! One preset inverted, for comparison ...

Re: How to HFD five Hypex FA502 plate amp (for active subwoofer only)

Time to close the loop. I am very pleased with the purchase. And easy to setup too! At least for my usage. As my main speakers is LR 4th order therefore it made thing easier. I would see the set up as a three ways, i.e. full range, upper sub and lower sub. All lowpass and highpass were LR 4th order,...

Re: How to HFD five Hypex FA502 plate amp (for active subwoofer only)

With crossover points this close you will never get it right or you must use 48db/oct filtering minimum. Do you mean the xover point between the two subs? 1. Sub A - one pairs of 2x10" drivers, sealed, to handle 40Hz to 120Hz, fourth order 2. Sub B - three units of 4x12" drivers, sealed a...

Re: How to HFD five Hypex FA502 plate amp (for active subwoofer only)

maybe this software can be helpfull: http://andyc.diy-audio-engineering.org/mso/html/index.html Thanks! This provide a good read, and another alternative to multiple subs config. What I'm thinking of is to add-on to one another, i.e. Sub A add-on to the limited full range, and Sub B add-on to Sub A...

Re: How to HFD five Hypex FA502 plate amp (for active subwoofer only)

Why this strange sub construction? :think: :think: :think: :think: I am looking at upgrading my existing system with minimum costs, and fusion plate amp allow me to directly digital the subs after I've familiarised with how analogue works. The Hypex HFD provide a mean for me to configure, measure a...

Re: How to HFD five Hypex FA502 plate amp (for active subwoofer only)

OK, then here is my take on the first question. I have never used anything from Hypex, so I can only answer generic questions that are not specific to Hypex. 1. I'd go for Butterworth. Unless the differences between the path lengths from the mid/high loudspeakers and the subwoofers to your ears are...

How to HFD five Hypex FA502 plate amp (for active subwoofer only)

As FA502 not available yet therefore I didn't ask Hypex. I am planning to replace plate amps for five active subs: 1. Sub A - one pairs of 2x10" driver, sealed, to handle 40Hz to 120Hz, fourth order 2. Sub B - three units of 4x12" driver, sealed and isobaric design, 40Hz and below, fourth ...
