[dsime42]

Tent Sale?

You missed out on the JBL Tent Sale awhile ago .. It was around $120 for a JBL 4648 bass unit (contains two 2226J) which the price includes shipping. I brought 2 units. The Cabinets was Huge.

So they gave you two drivers and a bunch of wood if you paid for the shipping?
Nice

The Eighteen sound 15W700 is a much better choise if you want ferrite magnet. They cost new what JBLs cost second hand.

The Faital Pros are much better, but a bit more expensive.

Thanks for the speaker suggestions.

JoshK don't think twice about Faital Pro I will be using them as soon as the plans are available, I think they are the best now from Italy built wise and reliability and sound wise. I have heard them in double 18" BR cabinet in Miami from a sound company last year for a Band/DJ show, it ran flawlessly for 18 hours continuously all night till morning (18XL1600).

No TH_1819 build ? with 18XL1600 driver it is still one of the best subwoofers I have ever heard

Hi ZivkoF, I am still 50-50 because the Faital 18FH500 price can't be beat it is a very good design for the output. I like the 1819 for it's size and simple build, still looking for a better driver since the 18FH500 may not be strong enough for the rigors of PA use. Any other suggestion like the faital 18HP1060 driver would this work to 30Hz? Since this is a stronger woofer than the 18FH500 for the TH1819? thanks!

Hi djlivex,

the Faital 18HP1060 will work just great to 30Hz as at 2Pi sensitivity is 96,51 dB @ 1w/1m and SPL it is only down -6,63 dB @ 20Hz (89,88 dB) and SPL is 97,32 dB at 60Hz.

FreeCAD is fantastic! A bit buggy but very very nice to work with.

An externally hosted image should be here but it was not working when we last tested it.

Good work. I just watched a youtube video of someone using this software, and I have to say it looks to be quite a pain to use. Sketchup is still free and there are plenty of tutorials to get you going.

hi more 10
maybe i overlooked,but what are the dimensions of the cab?

 

[more10]

Latest revision is (HxDxW) 120 x 95 x 50 centimeters.

 

[NEO Dan]

Latest revision is (HxDxW) 120 x 95 x 50 centimeters.

That's pretty big, what were the old dimensions?

IC now:
The dimesions are (HxDxW) 1196 x 936 x 494. Millimeters

 

[more10]

Depth is increased by 12 mm because I added the bracing between left and right side as seen in the 3d drawing. Bracing is now 12 mm instead of 18 mm, so the width is lesser by 6 mm.

 

[more10]

That's pretty big

I made an excel sheet to calculate hornresp parameters for other widths of the box :

Try drivers with Fs ~ 40, Q ~ 0.3 and BL ~ 20 for an 8 ohm driver.

I have not been to a disco, or whatever you kids call it nowdays, for many years. How low does modern dance music go?

There's music that will easily hit low 25-20hz these days ! It's not uncommon ! It's always bad when everyone is enjoying the song then the bass dies !!!

"There's music that will easily hit low 25-20hz these days "

Then you need a Danley TH-50 tapped horn with the TC Sounds Pro 5100 driver.

This is a very appealing folding solution from a DIY perspective, just as elegant as it is simple, just rotate a square within a square, brilliant, I have been toying with the idea to have the driver access in the angled mouth panel thus adding a bit of length (roughly 400mm in the 15" case) to the horn, the box will become bigger if everything else stays the same so some tweaking is in order should one pursuit that idea.

I know this has been our for a while now, but it still is worth attention in my opinion, thanks for sharing.

 

[more10]

Thanks for the flattery Martinsson!

As I have said before, it is inspired by your Tham series of designs. All angles except one is 90 degrees.
