New Woofer - Click HERE for Original Thread
Mikey p
Just a heads up. There's a new woofer coming on the market from Mach5audio called the IXL-18.4. The specs are:

Fs = 15.4Hz
Re = 3.2Ohm
Qms = 4.87
Qes = 0.39
Qts = 0.36
Vas = 556L
Sd = 1029.2cm
BL = 15.1
Mms = 228g
Cms = 0.37mm
SPL = 89.2
Xmax = 22mm

Pricing has yet to be set, but I'm willing to bet it'll be affordable considering the other Mach 5 drivers. Personally, I can't wait to build a couple of HT subs with these!!! You can read about it here.

FOAM SURROUND .....................UGH!!!!!!!!
Cal Weldon
Ugh?

Why on earth would you say that? A lot of persons prefer the foam surround.

Some last 20 years. How long are you planning to keep a woofer for?

I'm not sure what the "icky" refers to. I have a pair of Celestion Ditton 15XR speakers from 1979 that haven't missed a beat yet.

Update. I emailed Mach5Audio about the pricing. The preorder will be a 20 dollar deposit. When the subs come in it'll be 175 U.S. which includes shipping to anywhere in North America. Sounds like a good deal to me. I'm getting 2 of them. Can't wait to install them up in my home theater!!!

:rolleyes: = I'm kidding. Not a thing wrong with foam surrounds. I have 2 MJ-18, they have foam suurounds. For the money, these subs are amazing.

wow, fits in my 200liter closed, -3db/30hz and -12db/15hz, pretty good - Fs=15hz at "only" Mms=228gr

Hi,
This woofer looks also promising for a sono-tube application.

As I don’t like the normal vented variant with the driver at one end and port at the opposite, I tested a TL variant I don’t remember the design origin of.

The tube was 225 cm and seems to work well for this new driver but - 10" less = 2 m even better and more optimal.

Driver sag is within rec. limits and for Usd 175 it looks like a bargain.

For anyone who is interested, I saw it posted on the mach5audio forums that the pre-order ends April 6th. Now to be patient and wait for my 2 monster subs! Cutting 6 sheets of 3/4 MDF for the boxes should keep me busy for awhile.

The new subs have arrived. The production T/S parameters have changed from the prototype. The VAS is now half of what it used to be. The new T/S parameters are:

Fs = 17.7 Hz
Re = 3.4 Ohms
Qt = 0.37
Qes = 0.39
Qms = 5.59
Mms = 434.3 grams
Cms = 0.184 mm/N
Vas = 274 liters
Sd= 1029.2 cm2
Xmax = 22 mm
Diameter = 36.2 cm

Notice the FS and sensitivity are also slightly up. Here's a few pics of the subs.

At under 200 U.S. for these subs, it has to be one of the best values out there. I'll be building 12 cubic feet tuned to 16 hz for these subs. Can't wait to see what they put out in my home theater!!

Hi,

FYI; The new T/S production parameters show better FR performance for the sono-tube application, see the revised picture where only the T/S is changed.

They move some serious air. My wife is contemplating hard on replacing my 7' towers in favour of these. Of course they won't be towers...
