Default Fane Colossus 18 XB subwoofer

Hi,

If you would like to see information about
my self designed subwoofer, you can take a look
at the following address:

http://www.karoliinasalminen.com/fan...tructions.html

Not best possible driver for home subwoofer, but
sounds quite ok despite of that. Not as good as
Velodyne HGS-18 or Genelec HTS-4 though.

Best Wishes,
Karoliina

the Fane drivers are probably a little underrated actually. if they're good enough for Funktion One (albeit custom versions), then they're good enough for me.

Not too underrated, the driver is quite good, but there is one
problem in it and it is the relatively short X-max and high
resonant frequency. For home theater subwoofer, also a driver
with Fs lower than 20 Hz could be beneficial. The Fs in this
driver is >30 Hz. The impedance peak is on the usable range
and with 100 ohms it is a problem to the amplifier, it can't
give enough voltage out unless it is a very big one (NAD 216 THX is too weak unless it is in the bridge mode where its performance is adequate with Fane).

North Leviathan would be very nice with
its 38 mm Xmax and Fs of 14 Hz.

that's quite a small amp for that Fane driver - most stuff i know of that uses Fane drivers is PA so loads of power out the amps is less of an issue than with home cinema stuff.

the other thing which might be a factor is if your sub is a direct radiator - all the low and mid stuff i know of with Fane drivers is either bandpass or horn loaded.

for going down to 20Hz and getting trouser flapping stuff you can't beat that PD 24" driver they use in the Turbosound sub. i think the PD1850 goes pretty low as well if you want to stick to an 18".

I'll check the PD driver. Could you please give me the link?

But how about
Adire Audio Tumult?
http://www.adireaudio.com/diy/Drivers/Adire/tumult.htm
More than three times the displacement of 18" Fane
with an 15 inch driver.
The size of the driver is not an issue but the enclosure
should be preferably reasonable so that I could fit it into
my apartment. The Fane sub is already taking one cubic
meter from the room.

Most amplifiers give out a constant drive voltage. The impedance curve of the speaker shows how much current is drawn at any specific frequency. As long as the lowest impedance in the speaker's frequency range can be handled by the amp, there will not be a problem.

As long as the Fane or any speaker has a smooth frequency response, the height of the impedance at any frequency does not matter, as long as the amp has enough current to handle the lowest impedance it hits.

If the frequency response is smooth around 100 Hz, the amplifier will not have to give additional voltage there, even though the speaker is drawing much less wattage at 100 Hz.

I notice that Adire does not list a dealer for Finland. I would suggest you call or Email Adire about that. You know how companies are about updating their website-they might have one in Finland after all. Here is the Contact Page from their website. I personally find a phone call is often the best way to get info like this.

Default Adire

I live in Seattle and I got a chance to check out the Tumult last week at Adire headquarters. I'm not sure it's "done" yet, but the prototype driver they had hooked up to the test equipment looked finished and even more impressive than the very impressive picture they have on the website (HUGE backside). Even without being in a cabinet, this thing was vibrating the place in a solid and even fashion, and the linear excursion is simply stunning. The cone was coming out of the basket so far without distortion I could barely believe my eyes.

I would definetly call Dan to get the complete info. He was really nice and had a straight answer for all my questions. Like I said, I'm not sure if it's in production quite yet, but what I saw seemed ready to go. Someone please correct me if I'm wrong. This is definitely a sub driver to consider even if you're on the other side of the world.

The PD 24" driver is at :

it's a monster of a driver, but it does sound good.

Hi,

I got some information from Adire audio about Tumult...
It appears that my next sub will be built upon Tumult. :-)
This seems to be better than North Leviathan in terms
of displacement.

Best Wishes,
Karoliina

Does the "displacement limit" mean the same as Xmax.
Is is one-way or two-way? I suppose that two-way.
