So it appears you are tyrying to "be cool" and keep up with the neighbours rather that trying to get good sound.

what exactly is stupid about the question ?

you don't agree with my goals - i don't agree with yours.

i guess that makes you an idiot - right ?

or did you wait like a slave until others voiced their opinions so you could mirror them and get a pat on the back from fellow sheep for being a good boy who never thinks for himself and only can voice the sentiment you pick up from others  ?

yeah i thought so.


LOL, you obviously don’t have a clue….. and you have no idea who you have just called an idiot!!

Robbo is most certainly no idiot or a sheep.

Anyone who needs one 21” subwoofer let alone 8 in a house clearly can not design, build or tune a worthwhile subwoofer. End.

The link works perfectly for me, must be something on your end.

It was something similar but I don't know if it matters. You're all over the map, you say you don't want cheap junk but then mention Crown XLS which are the cheap chinese junk you're trying to avoid. You want Powersoft or Lab Gruppen but you're "broke and want the cheapest gear possible", but then turn up your nose at the chinese stuff. The caribbean island crews have been flogging some of these big chinese amps for years now and they have gained in popularity because of the performance delivered. 
In a brand name amplifier the most affordable option may be these... T604 - Powersoft yeah still not exactly cheap but there is no middle ground in the high power multi channel amplifier market.. in case you hadn't noticed.

If you want deep bass, and dont need oodless of SPL, get some old JBL TCB subs. Dual 18“ bandpass in a massive box. They go low! And can be found really cheap :)

Line array, if you're serious i suggest you state your budget, music type, a detailed description of the space and ask the people here to suggest a solution for you. 

Just throwing your own ideas out and trying to get people to pull them together wont yield useful results in the same way.

An excellent choice. I remember JBL providing a Sound Power system for a Ministry Of Sound club tour back in the late 90s. Made the news here as during a sound check, they managed to blow the windows out one of the venues.  Smile

Just go into a US hifi shop and ask for a "Mugs Eyeful". I'm confident that someone will point you in the right direction. Oh, and I almost forgot. You'll definitely be needing the TK-421 upgrade to boost the bass by atleast 3 or 4 quads per channel.

Hard disagree. It’s not about the output level from the single box, it’s about decorrelation to provide far more consistent tone and level across the listening area.

Unless you're arguing that folks like Earl Geddes don't know how to make a subwoofer?


Yet another example of why this forum is so damn stagnant, dealing with the same old cycles of the same questions.

To the OP: head over to diyAudio. Plenty of folk experienced with MSO and the like there.

first of all thank you for not being a Troll and actually trying to answer the question.

you say Crown XLS is cheap Chinese junk ... i can see how an amp that only weighs 10 lbs and has RCA inputs and "DSP" that misses basic functions like subsonic filter or delay can be considered cheap junk ...

but they're some of the quietest amps ( in terms of fan noise ) on the market and unlike the Sinbosen stuff you can buy them from a reputable store, send them back if you don't like them and even ( GASP ! ) get warranty service if they need it.  

even though everybody on AVS runs those sinbosens and they break left and right i have yet to hear of ONE case of Sinbosen fixing anything under warranty.  it's always "i tried to contact Sinbosen and not much luck" ...  on other had they also all run XLS and i have yet to hear of even one XLS breaking at all nor have i ever heard of Crown not honoring warranty on their amps.

what do you mean by Caribbean Island crews ?  are those guys extra good at soldering or something ?  what makes them like these Chinese amps if nobody uses them here in US professionally ?

also the FP20000 is supposedly class TD which isn't the ideal type of amp for subs ... can you post a link to some other website with the same amp ?  maybe eBay ?

as for Powersoft T Series ... you will accuse me of flip flopping again because i said i don't want to waste an entire rack on subwoofer amps but actually i don't want single rack unit amps either ... i just don't like how they use all these weird fans and then they only pull the air over the heatsink instead of the entire amp because they used all the space in the back on the XLR plugs and only had room left for a tiny exhaust hole ...

i really like how military / industrial the ottocanali looks inside:

https://youtu.be/VCAOWEtj2TQ

it looks like it was pulled form some kind of Soviet Space Station while the 1RU powersofts look so pretty inside you can't take them very seriously ... they almost look like the Chinese fakes that paint aluminum to look like copper to beautify the amp on the inside and then decorate it with extra fans that do nothing except make noise ...

basically what are considered go to subwoofer amps for EDM ?  i guess you already answered with that Powersoft T series but what if we limit the options to 2RU amps ?
