Hi! MMJ and contributors.
I've read this thread back and forth multiple times and have seen the b&c 18tbw 100 mentioned a couple of times but can't find the specific point where it was said to work in the classic "c" type.
I am VERY interested in using my pair in either a type c or the paraflex pro mentioned in post 841.
I'd like to have the boxes with either a 36" x 36" x 24" or 40" x 36" x 24" size as i am limited to the 24" width and 40" height.
Can this be achieved to get a 35-38 hz f3?
I don't have access to HR for awhile as all my computers are packed away for the time being.
Love this thread!!
Thank you for any info you can share.
 
You can do it!

Top Shelf,
Glad to hear you are enjoying the thread! :) You might like it even more when you hear the following good news :D Yes, you can use the 18TBW100 from B&C in the Paraflex Type "C" Classic or the Paraflex Type "A" from post #841 , and yes either of them will work at 24" (61cm) outer width using that driver ..... We have found that in the real-world these two layouts are more tolerant & forgiving than our initial simulations had suggested ....... The Type "A" can even be configured as end-firing so in that case (with enough coordination) you wouldn't need a removable access panel hatch ....

NOTE: Sufficient internal bracing (as we see in Ziggurat's build) is very important in Paraflex builds ..
 
Hi Matthew.
That is great to hear that my drivers will work in those cabs. Thanks for getting back so quick!
I just measured my storage space height and have found that i can actually have each cab at 43 inch height so that's even better.
Hopefully i can grab my buddies laptop and download the latest hornresp version. I love modeling bass cabs.
Thanks again man!
 
Hi resko.
Nice build! What are you going to coat the cabs with?
Any bracing going in the mouth?
Do the 4 -45° fill-ins change the tuning of the large front resonator at all?




Will be coated with duratex. same as my smt 212 top cabs. As of now, no plans for mouth bracing. But i can always add that later on if i see issues with mouth flex.

And yes, the high tuned resonators extend the upper frequency range. Ive gotten up to 160hz so far with no breakup and minimal eq. These cabs eliminate the need for kick bins if used in an array. If i could post a video....



Anyways. Tops are loaded with b&c de780tn compression drivers and b&c me90 horn. Woofers are Lavoce WAF123.01's
Paraflex c2e silver formulas are loaded with Lavoce SAF184.50 drivers.

IMO, all of it is an amazing combination that needs little eq, kicks like a mule, and digs deep for those low notes. Im highly impressed and ill be adding 2 more paraflex c2e's shortly.

Nice rig man!
How would you say the sound is compared to a typical reflex box? Just plain louder, do you get any droning in basslines? Eg., overhang of notes.
How does the lower end of a kick drum sound thru them?
Sorry for all the questions but I'm pretty pumped with all the info I've heard about these cabs.

The impact from it is similar to a reflex, but sensitivity and smoothness of a horn. Imo louder then some of the tapped horn designs on here. I was going to build the xoc th18's with the cone correction but opted for the paraflex. Glad i did. Kicks are strong around 80-90. Rolls off about 32hz. Normally i leave my LP at 100hz with tops crossed at 85. I did notice a resonance around 90 as well. But my high tuned resonators wernt fully sealed on the sides. Ive resolved that and ill be able to see if it made a difference next saturday. I have a gig for a local jam fest. Hip hop, rap battle, and beat boxing.
 
Here's a cool pic of the innards of the second cab being built. This one is gonna get ebony wood stain instead of brown to match the two-tone look of the rest of the system.

Getting the rear panel of the baffle to sit snugly between the top and bottom is a tricky clamp job and involved taking fractions of a millimeter off of the panel at a time with the table saw.

Hi Zig. Nice cab.
Are you going to paint the inside of the low tuned port area before you close it up? Oops just just saw the colour in post 1199.
Will your driver have enough "throw" room for xmax or xmech with the braces just flush behind the driver mounting baffle?
