Unless you are pushing the amp you have it seems like a bit of a waste of money Steve, doubling the power will only add 3dB more output. Seems crazy to spend over 2 grand for 3dB doesn't it?

The plan is this. 2nd 18.2 with 1 amp. 2400x2.

You are right. I won't get another amp. I will get more 18.2s...
Are you suggesting I go for 3?
3 such an odd number 4 is a much nicer number and keeps things symetrical in the room. Maybe we could stack the 18.2s or something.

Today my 18.0C subs arrived, which are gorgeous and they look great in my room. Each sub has 1000 watt amp with full DSP, comes with RCA to XLR adapters as there are no RCA inputs, and 10 feet of power cables. I will post my impressions of them sometime next week or so when I have them fully setup. For now, I will just post some pics of these beasty looking subs.

Question

mmm... I wonder what a 18.0C would do in my 19L x 13W x 8H room? Any idea if the 18.0C is as clean as the 18.0 but with a little less output?

I'm selling my Martin Logan Depth i which was very nice musically but lacked impact.

I asked the same question before I decided on dual 18.0C. Nathan advised me that the 18.0C offers the exact same sound quality, same features, is slightly smaller and does 2-3db less overall output at 'all frequencies'. If you look at data-bass on the 18.0 and shave off 2-3db, that's still very loud. Look for my impressions next week or so on the 18.0C.

Musicality will be the last thing you worry about Any of Nathan's Subs are all quality in mind

I wonder... Who's Sub is this? Must be one of you guys...

Looking at pricing on Funk website is US dollars and due to the differences is the Canadian dollar right now, I'm not sure these subs are as good a value as they used to be for Canadians.

Yeah with the current exchange rate its basically a 15% adder to the price for Canadian customers.

For Canadian customers we can often arrange some discount depending on actual shipping location/costs(varies more within Canada than the USA, for distance size and weight), payment method, specific product, and current exchange rates. As many of our supplies are USD based we have to base our prices on USD, but there are these variables we can consider for Canadians, on an individual basis.

Yes cant wait to hear your impressions. I'm seriously considering one..

2-3db off the 18.0 I assume would be with two 180.0C ?

No, that's a single 18.0C. Dual 18.0C would have slightly more output than a single 18.0. Three 18.0C = Two 18.0.

If those are dual 18.0's, then I think they might be mine. Nathan said he just got done venering mine. Either way, it's impressive to watch him build these subwoofers.

My work in progress: Sony KDL65w850a, Oppo 105D Darbee edition, Marantz 7702, Marantz 8077, W4S mAMPs, W4S DAC1-LE, Sonus Faber Olympica III, Dual Funk Audio 18.0, Sonos, ML center and surround speakers, cheap Onkyo Atmos speakers for now, decent cables (Cardas, Pangea, Bluejeans), APC H15 power conditioner, Logitech Harmony Ultimate (for the wife obviously), Roku, minimal GIK acoustic panels...

Now I have a decision to make. Its going to be between the Funk 18.0C or the Paradigm Sub12. Being a Canadian both subs compete closely price wise. The fit and finish of both subs are great so I just need to get more info on the Sub 12 if has comparable performance..I will demo one today but I can find any published numbers on that sub anywhere.

The Funk 18.0C would have a lot more noticeable output over a Sub 12. I've heard one and my PSA XS30 that I had would of easily outperformed the Sub 12.

Agree. The standard FW18.0 is practically dead even with the Paradigm Sub 2 from 25Hz on up, and only 3-4dB behind from 20Hz on down. If the 18.0C is only 3dB behind the 18.0, its hard to see the Sub 12 keeping up given that it has a quarter of the cone area and a little better than a third of the power of the Sub 2.

I just finished a home demo of both a Paradigm Sub12 and the JL Audio E112. Tried the Sub12 first..thought mmm not bad. Definitely cleaner than my old SVS Ultra. Then I tried the JL 112...Immediately packed up the Sub12

JL E112 was much more musical and hit harder. Note both subs were in the same location and level. Neither was EQ'd. Now now I'm still thinking 18.0C ...decisions haha

Unless you need to worry about the size of the subs there is no way I'd take a E112 over a 18.0C. The only way I'm taking the E112 was if its free!...lol
If I'm having to pay for them it would be the Funk 18.0C all day long.


I will say though that if I was going to buy a big brand name sub though JL's would be near the top of my list and they are nice subs. I just personally prefer other subs from the ID sector.

Have you heard the E112? Databass measurements between it and the 18.0C are pretty close. Funk cabinets are very nice though.. and no, size dosent matter lol.

I haven't heard any of the E series of subs, only the F series. Keep in mind the data-bass numbers are for the older 18.0C sub, not the new revised unit.
Everything about the Funk 18.0C is higher quality IMO.

The Funk Audio TSAD18v1-8 driver, a variation of the current series 18.X Series is used on the 18.0C. The new one should be better performance wise. It certainly looks better though. I think the sound should be similar to the 18.0 with very low distortion. dB isn't everything for a subwoofer. What is also important is the harmonics and other factors that effect how "tight" and "clean" the subwoofer sounds.

The Sub 2 produces a 3rd harmonic at about 40+% on at about 12 hz. That would translate to something at about 36hz. That would translate to -7.9dB below the fundamental.

So if you play a 12 hz and you get a note from around 36hz. Funk should give a lower distortion all the way down low and won't effect the upper notes. This most likely would likely result in tight bass because of the low distortion. Some movies contain deep bass, the last thing you want is some odd note popping up from somewhere

3rd Harmonics is kept very very low with the 2nd in a pretty much an inaudible level for the 18.0.

TSAD18v1-8 driver, a variation of the current series, should yield similar performance minus some output. Maybe same low distortion I want a demo

Go for it, Funk Audio is the King of Subs… Tight bass… and you get to pick a veneer Funk Subs also excel in upper bass, they are actually very very good at it. They will hit very hard. If you like hits without a doubt Funk is the way to go. Since the bass that gives you that kind of impact is around 120hz ish, I think you will like it a lot.

I'm with jbrown, take the Funk 18.0C Maybe Nathan can input some info.

Yes, it's possible to beat on the Sub 2 hard enough to get it to produce >40% THD at 12Hz. OTOH, if you look at the CEA-2010 burst results for the FW 18.0, it is also capable of producing a substantial amount of THD.
http://www.data-bass.com/images/meas...10%20chart.png
If you look at the right side of the chart, you'll see at 12.5Hz, the FW18.0 will produce up to 71.3% THD at 12.5Hz and 88.3% THD at 16Hz. We don't know the complete breakdown, but the FW18.0 was limited by 3rd order harmonics at both points, indicating sufficient levels for audibility.

In either case, I'm not sure there's not much relation to bass tightness vs THD when you're going out of your way to beat the crap out of a sub.

PS: The third harmonic of 12Hz isn't 50Hz. The 2nd harmonic will be 24Hz, and the third harmonic will be 36Hz.

I thought that the THD sweeps were done at maximum loudness levels, and by that metric the 18.0 just barely goes over 20% in the 120v mode. I guess that wasn't max levels.

The compression sweeps (to which the THD graphs are tied) are done as high as Josh is willing to push them. As the FW18.0 was pumping its limiter in the 120dB sweep, there wasn't much point in continuing. Obviously CEA 2010 testing using 6.5 cycle tone bursts is a bit different, and can result in higher output, along with higher distortion.

If you look at the right side of the chart, you'll see at 12.5Hz, the FW18.0 will produce up to 71.3% THD at 12.5Hz and 88.3% THD at 16Hz. We don't know the complete breakdown, but the FW18.0 was limited by 3rd order harmonics at both points, indicating sufficient levels for audibility.

In either case, I'm not sure there's not much relation to bass tightness vs THD when you're going out of your way to beat the crap out of a sub.

PS: The third harmonic of 12Hz isn't 50Hz. The 2nd harmonic will be 24Hz, and the third harmonic will be 36Hz.

Yes, you are right. Somehow screwed up the 3rd order calculation (Don't know how I did that - Now corrected)
I was looking at 18.0 (Not named as component) Under-multiseries (115, 120db)
http://www.data-bass.com/data?page=s...id=96&mset=103

I was looking at THD Sweeps under Multi-Series Sweeps

Did recheck the Sub 2, Listed as THD - Component =/

But other than that



Better long term output after 25hz at the more vital frequencies. Nice boost at 10hz with room gain so should be all good. Of course depends on the room.

Considering price performance ratio, it's a lot better.

I think Ricci did continue testing. He used his K10 Bridged... Lots more THD(Driver limited). Its listed under passive Cab I believe.

Note that the Sub2's long term tests were nerfed as the system shut down as opposed to simply limiting the low end after the 110dB sweep.

During the very low bass portion of the long term output compression testing the Sub 2 shut down twice during 115dB sweep attempt. At first there was concern that a fuse had blown or something had been damaged in the amplifier but it was simply a protection circuit which takes a few minutes to reset. The large amount of EQ boost in the 12-18Hz frequency range is the area which caused the protection to trigger. Because of this limitation, testing at higher levels with the long term sweep signals was stopped. The maximum level reached is somewhat misrepresentation as the Sub 2 had a large amount of output still available at higher frequencies.

No doubt!

True enough.

Too bad Ricci can't power the SUB2 with the K10

Btw

I don't think I've seen pictures of your 18

Here's a nekkid shot with a KEF R500.

I actually got it when my mains were black, and I'm considering having a new cabinet finished to match my new setup. Other priorities on the table though.
