21" Active subwoofer project

Village Plank · 28th January 2009, 02:00 PM

I'm starting a monster sub project using the PD2150

Also the RYTHMIK A370SE sub plate amp caught my attention, Ideally I would like a plate amp of 700W rms +. any ideas on where I could find one?

Excellent quality amps. Its only 500W rms but probably has more true power than many amps that claim 700W. Nice beefy power supply and a pretty reasonable price tag

Omnes Audio makes an interesting digital processor fore subamp, mono and stereo versions

You could use any 1000W pro amp

Village , why not 24 inch PD2450 and even for 21 inch one you need atleast 1500WRMS amp to do the justice with dynamic range.

Sorry to jump in but i'm also building similair project:
Tony Gee Serious Sub
but i will use PDN.2151
What kind of active crossover do you guys recommend?
Maybe something from Elliott sound products?

Omnes Audio have a nice digital eq/filter

Sorry I answered the same twice, must have been my bedtime

I have looked at those big PD woofers several time, calculated over and over again, and really dont see what it is they are supposed to do better than other woofers, apart from SPL and powerhandling

It has been mentioned that TonyGee use a PD woofer with similar specs

To my limited knowledge about TonyGee I would say that what he consider a very nice bass, many would rate as no bass at all

Please, I dont say he is wrong though, its a matter of personal taste

Sure you got that right that is personal taste and preferences what counts. I think he have good theory and i like what he is done in practice to support it.
Will see, and hear
