looking for weight reduction = easy to carry & lift / stairs , etc.---> look for neodimium magnets
like:
B&C 18NW100,
BMSpro.info 18N850
aurasound NRT18-8
& others
looking for deep subs 32-40-50Hz-64Hz, ? feel it
2x JBL 2241H in a 18cu.ft or 509liters box, tunned to 33Hz.
or 1x 2241H in a 9cu.ft box
the JBL sounds great & feels great original its the SR4719A/2/x
but remember fletcher & munson equal loudness curves
http://en.wikipedia.org/wiki/Fletcher%E2%80%93Munson_curveshttp://www.rane.com/par-f.htmllook fletcher munsn history
looking similar deep performance in a smaller box?, look for RCF L18P300. box like meyer 650 clone, i think its better than Yorville TX9s,
looking for +3dB loud bass? hear it loud, 100Hz-200Hz, but not loose much of the deep ?
look for RCF L18S800 or Beyma 18-G50, in a vended box, 6cu.ft 38Hz each driver,
Beyma 18g50 its more recomended becouse it has the biggest SD of any 18" has more than a SD of 13!!!! and 9mm Xmax!!!!, and great BL!!!!
want an even Louder bass, but not sub bass, ???
cerwinvega B36 clone, or T36 clone, with Beyma 18G50,
or many similar folded horns, that are like
http://www.cerwinvega.com/products/professional/vegabass/ima ges/foldedhorn.gif
S shaped or longer complex W-Bins like EV TL4025 TL4050, or EAW 882 bertha subs need a stronger cone and lots of BL and Xmax, McCauley 6174, Aura NRT18-8, BMSpro.info 18N850 has 31BL and 13mm Xmax but unknown cone strengh at least equal to all paper cones out there,
the ciare 12.00sw 15.00sw & 18.00sw, have a poor SPL response in the 100-200Hz but have the strongest cone, and great BL,
cerwinvega has the T-36 but does not sound earthquake to me,
but has an interesting BL52! and 1/2inch Xmax,
or download the Electrovoice TL4025 1x15" vintage plans at he bottom links, and multiply it by 1.2 x 15" = 18"
or
http://members.aol.com/xxbase80a/its a great site, he has made all those vintage box plans, and MEASURE THEM! the Freq Responce!!,
has the JBL W-Bin 1x18, but the html code its grong, but the files can be accesed by this link:
http://members.aol.com/xxbase80a/w18.bin/the TL40XX response curves are a bit dissapointing, I guess becouse the drivers that were used! a new stronger BL , bigger Xmax, would / should give better results!
thats why i want to make them, just for fun
or at least recreate them in the hornresp software thats so great!
http://www.users.bigpond.com/dmcbean/but read first the GREAT Help tutorial at:
http://www.diyaudio.com/wiki/index.php?page=LoudspeakerI think/heard the JBL keele W-Bin 1x18" its better
has the loude bass and becouse it has a vented box it has also verry nice deep bass, but intead of the JBL 2240h, a Rcf l18s800 or a beyma 18g50 would be extreme better!
the site says that the 2x15 W-bin has more than JBL W-Bin of deep bass, but... becouse it has 2 drivers that sums way bigger SD, also its wider and does not fit in small doorways ,
i like more the 1x18 ,
even smaller box with out loosing subs? ISOBARIC its the name,
isobaric means twice watts, half box, in speacial driver compound,
isobaric its great, if you like small, and deep,
you can make Isobaric compound = 2x 18" drivers facing in a push+pull separated by a 1" or 1.25" wood ring = same signal , same watts but 1 with reverse polarity = 1 isobaric = 1 normal but isobaric has half 1/2 the box size, and quake feeling increase, becouse the twice hard cone mass & twice watts,
no other desing beats the deep sub bass in such small box, too bad JBL 2241H has a bit dificult to make in isobaric becouse the aluminium in the speaker its lower than the foam = too bad becouse the JBL 2241H ask big box for deep bass,
it could be done by cutting or melting the foam at the level of the aluminium and usign 1.25" ring or 2 glued 3/4" rings at the edge, should be so GREAT to make them, a 2x Isobaric of 18" JBL 2241H, its a real portable QUAKE , 2 isobarics of JBL 2241h in one box, but just one isobaric gives great deep in a incredible 1/2 enclosure! but Xmax mmmmmm,
or Aura Sound NRT18-8 has similar box requeriments and freq. response than a JBL 2241h in any software but with way bigger Xmax of 18mm and great BL!
Just BEWare That front facing Isobaric needs more than 6mm of Xmax, driver reach the Xmax too easy,
the EV EVX180B dont have enough Xmax
The McCauley 6174 also asks for big vented box to deliver deep bass in the sotware, it looks in the software that could be great for front isobaric too!
also BMSpro.info 18N850 looks GREAT, but has a bit poor freq. response, but has 1200W, or others could be great, even the Ciare 18.00SW but has even poor SPL,
or Beyma 18G50 that has such great SD!, 1 isobaric in a 3.cu.ft box tunned to 33Hz? or 35Hz? or 38Hz? imagine that!
the eminence software, gives a compound isobarich in puch pull, both drivers separated by the same box, BUT, only if the box has 1" or better 1.25" MDF , and a real door,
its easy to make a 1" 1.25" ring to separate them, and use really LONG Screws! with butterflys
Isobaric its great for cars with small space,
look download eminence.com designer software for more info,
http://editweb.iglou.com/eminence/eminence/pages/products02/ cabinet/maincab.htm
make any box in MDF with lots of wood glue & long wood screws, 3/4" if you want light, 1" if you want strong box, minium for isobaric, or 1.25" MDF = the best but really heavy,
be shure to make wheels like community vlf-218 or meyer 650 makes life really easy to carry arround, JBL original SR4719x are almost imposible to carry, but sound great
then buy some plastic black finish to paint the boxes, make several layers, allow them to dry enough,
and for vented boxes, 1 big vent port in the center of the box for 2x18", i think and hear sounds better than several smaller ports, BUT manufacturers lke makie say that more distributed ventss are better for cone distortion at high drive levels, your choise, make 1 big 33Hz vent for 2x18" in a 18cu.ft or 8 smaller vents arround the 2x18", or make 4 for 1x18" driver,
unless its the W-Bin 1x18", your choise
to make your own boxes you must have access to a table circular fixed rotating saw with mettering, AND a fixed wood leveler table also with mettering and angles, thats a drum roll with 3 knives rotating in a table, AND a powerfull more than 400W Electric Driller with reverse and some screw heads, to screw the screws,
wood sides must fit perfectly before glue and screws,
want a concert SPL sound? emacoustics.co.uk ms-118 in groups of 8, minium 4x,
EAW DSC2 , bh822, la400, bassmaxx
all horn loaded bass must be in groups of 8, horns need to be big to fit the bass wave lenght, or wont go low,
or make your own, keele JBL 1x18" W-Bin in groups of 8, 2x4,
or buy them made from sonic or used from stageaccompany.com vintage used to make that keele JBL 1x18" W-Bin,
use the W-Bins with Beyma 18G50, or RCF L18S800, or RCF P300, or others that make almost JBL 2241h deep bass in a 5.cu.ft 35Hz box,
or make the precision-devices.com 2x24" PD.2450, WOW!!!
that could sound & feel so Amazing! with a RMX2450 for each box 2x24"

i made my self , a community VLF-218, but bigger! to have enough Cu.Ft for JBL 2241H,
originally i used 2 isobaric peavey 18" blackwidows = 4 in one box, sounded great BUT BlackWidows need bigger box= good for isobaric BUT have small Xmax = not good for Subs!, are OK for bass, but not subs
Now they are loaded with JBL 2241H , 2 each box, has a bit less deep bass than original SR4719x, but... has a bit more in 125Hz & 160Hz, way better than Electrovoice MTL-1x,
they sound really great! & really nice to me,
depends on your taste,
hear more bass or hear less but feel more bass
i like more to feel the bass, than hear it,
you could build a 2x18" vented and put a 4" 2" driver horn on top of it, like jbl 2446j + 2380a, or similar, driver and that sounds Great! and use bi-amplified with a JBL M553 at 500Hz, 24dB/oct, Sounds GREAT! & BIG!
or if you put lots of super tweeters like JBL 2405h or 2402h, or similar at 9kHz
SOUNDS AMAZING!!!
i have it like that, it just sounds BIG & CLEAR & AMAZING!
vented subs can be used for bi-amplified, sub horns must be 3-way,
i think & hear the pyle pro ppm501 "an eminence vintage design 1x15 mid box" sounds better than JBL 4560 mid box or peavey HD115 vintage midbass,
http://www.pyleaudio.com/EL/PPM501.jpgbut with a peavey 1508-8he or 15058 ka dt, or 1501-4 or JBL E130-8, or similar high efficiency 15" driver, would sound GREAT LOUD!! & BIG!@
thers another MB115 vintage midbass design similar to emincence but havent heard it, or dont know the measures to know if its better than eminence design, if its bigger deeper, its better, simple for horns
or the Peavey MB-1 or the MB-2, or the FH-2 subs,
