in case mr210 closed or br.
best use high quality neo 18" drivers(18 sound,b&c,rcf )tuned to 35~40 hz.
th's are bigger but produce more output vs amp load.
so if u have lots of power you could choose a br box,wich are easy to bild, but need more speakers.
wich labruppen you have for the subs?

punisher's rock but you need multiples to get low extension
Sub Amps are fp14000 series.

The th-118's look to be a good option as well as some Mini's. Which th-118 and Mini design/build fits my application best? There are so many configurations it's confusing especially not having the necessary understanding interpreting the numbers/data.

I must admit, I'm not really up to speed on the current crop of THs, so I'll have to let others advise you on those, but personally, I'd go for these with PD1850s. Very nice boxes.

Agree. PD1850 is probably the very best driver which you can find. Very nice sounding, accurate, .......and it really plays music even at high powers....one of my best investments.....50 pieces.....
Best regards, Taj

I was referring to the TH-18's because this is DIYaudio. The Danley TH-118's are great, but they are north of $3000 USD a piece. Ouch.

1>ranging from 200-1200 people
there is a difference playing in a hall with 1200 people in it, or giving a concert for 1200 people.the later needing much more output.

4>should be efficient.
this is a contradiction because >you can pick any 2 of small, efficient,and low.
meaning, if you want a box to be efficient and go low its going to be big.
if you want a box small and go low it wil not be efficient
if you want a box small and efficient it wil not go low

4>cost of build not being a issue
,this is why i advice quility drivers,they wil earn themselfs back over time.

Sub Amps are fp14000 series
.meaning 2 channels of 7000 watts@ 2 ohm per side.
this is a lot of power,you could drive 3 to 4 18"high power woofers from 1 channel.
some say you dont need to go low ,this is a personal opinion.
ive done a lot of pa-ing in my time ,and i always extend my lows to 30 hz(admitted i usualy playd for 200-600 people.)
its up to you and your experiance to say how low you need.
saying you dont want to pul a trayler,is not posible when playing for 1200 people when doing concerts unless you got a big truck
imo you could run 3 500~600 ltr 18"th per side for up to 600 people giving a concert.
that is 1500 to 1800 ltr per side.
or do it with 3 double 18"br cabs wich is about 1000 ltrs per side(using 2 amp channels)
see post 6 four a comparison.
the reason i asked wich tops us use is the mr210 doesnt do much below 300 hz, wich means the subs need to run that hi
in case of the jfl 210 tis is no problem as they go down to 65 hz

50 of PD1850. It is 24 double 18 subs, 12 per side and 2 spare drivers. At such amount you just buy 2 more...it doesn't make any difference...
I'm using it for open air concerts and closed venues as well......something up to 5000 people. It depends on program.
Best regards, Taj
