The advantage is the use of smaller sealed enclosures. You also get to lower the Q and Fs of the cabinet.
It won't do 120dB at 10hz but then again I never aimed for such level's.
I actually said I wanted 105dB at 15hz which is much more likely with 8 x 10's.
Don't overlook loading just to hit output targets. SQ is the most important part for me and with infrasonic that means low distorion, phase, GD etc. Sealed is king in these area's.
Admittedly you'll need a 8 x 15's in sealed enclosures to hit a comfortable 10hz at 120dB with acceptable distortion. Fortunately I don't need nor want those kind of levels. Which means I may not have bragging right but I'll be happy that I reached my targets and didn't compromise on SQ.
Again never said such a thing regarding iso's. My discussion has been entirely confined to sealed discussion but its the only way that I'd do it. Loading is just a way to cheat on output. Sealed is the least effecient of the lot but offer advantages in SQ that the others just don't.
Again its what you're looking for isn't it. I want the best SQ not competition level SPL's that I'll never use. Someone mentioned laying out definite goals and that's just what I've done: Sealed enclosures with EQ optimised for SQ and extension over raw output and extension.

I don't want competition SPL either.... I'm far more interested in MATCHING my speakers...
the entire system can reach levels of 116+ db over all the bandwith... so flat from 10-40hz with these abilities is a MUST in my eyes
I may or may not use it... but the MKIII has great SQ BTW and for normal play I'm sure I will be happy
there's just the coolness in throwing on some pipe organs and having it flat to 10hz 🙂

no, that's 100ltrs per woofer. That would be a sad sub with only 100ltrs and 4 x 10's in there.
I really fancy giving the Volts another try.
4 x 12" Radials might work or maybe 4 x Volt B2500.1's. The problem is that they don't like sealed cabinets at all from previous experience.
Anyone suggest subs with a Qts of around 0.4-0.5 and with low Fs, high BL and decent xmax(15-20mm+ one-way)?
You'd ideals of matching is admirable and its exactly the same over here.
If that's a must in your eye's then your entirely correct.
This test with the XLS vs. MKIII vs. Bully is very interesting:
http://www.mfk-projects.com/titanic_mkiii_vs_xls.htm
Its funny that the XLS actually matches the 15" MKIII at 20hz and rapes it at higher frequencies for distortion at the same input levels. Its easy to see why multiple XLS's would yield incredibly low distortion.
That guy wasn't impressed with the MKIII from specs and sound alone. He even commented that mechanical noise was a problem! Yuck!.
I'm sure you'd be better served with something else.
Coolness is great but when the dust settles and you've gotten over the wow factor, its all got to be competant. I'd take SQ over coolness any day. If you can get both then that's great.

Cheers Simon,
The Titanics look rough to me, people complaining of mechanical noise isn't inspiring. Distortion at low frequencies is disappointing for a 15" too.
The Stryke's(I'll always think of them as that) look good for the money on the other hand. I'll investigate somemore. But I understand there is a supply problem ATM?
Well, the owner was sick, dunno if he recovered.
There was a group buy were everyone wanted to buy that.
You could call the owner to see if he recovered.
I know that US orders didn't stop but we're talking about an overseas order here!

I'm looking into having TC Sounds create me a pair of custom made 15's based on the TC3.
I've asked for a design optimised for SQ, low extension in a sealed enclosure.
I'll see what they come up with.

A pair only so you can test performance? If good, a line
array is in order? if so -> 😎

TC sounds a year ago used to just build woofers with a little more than a sentence... it's harder to get them on board now adays
that's who I'm looking to to modify my lambda's eventually and also my midranges... adding extra faraday to the lambda and a counterwound coil and get them to put a faraday in a midrange to test the SQ vs stock
Finally finished the construction but now I have a bigger problem!
What do I finish them in? I was ready to get the compressor out again but the weather has been terrible here. Then out of curiosity I was looking around the web at veneer suppliers and found some quite exquisite examples for sale in quantity in large sizes and at reasonable-ish prices.
Here's a few that I eye'd up, my fave would be the first one, looks very fractal like with amazing detail.
So should it be the high tech purple green black flip finish or the veneered and classy look?
I'm half thinking about combining the two, not with the flip finish as that would look plain daft with veneer but rather glossy black with veneer insets patterned around the cabinet.
Damn I hate choices! Especially with the time involved if I don't like it.
On another note TC hasn't got back to me and I'm getting rather fed up of the whole subwoofer thing at the moment. I haven't even finished these yet so I'll let that be my priority and worry about the serious bass afterwards.

Post finished cabinet pics!! Lots of them!! =)
I'm going to give a big vote for the veneer, I much prefer that to the flip-flop paint. Flip-flop paint looks cool, but I think that in the long run you'd be much happier with a classy under-stated finish. Incorporating gloss black has the possibility to look the best if it is implemented correctly, the real tough part is deciding which parts are black and which are veneered. I'm sure you'll come up with something wonderful, but let me state again, you should DEFINATELY have some veneer in the mix!

Cheers motion, appreciate the input.
The flip finish looks weak in the photo's I've posted in the past, in person its quite spectacular, actually maybe a little too full on. That sort of stuff looks good on a bling'd out auto but on speakers in the house, well its a little too much I think. Cool at first though.
So I'd like to give classy I try I think. I've got the gloss mirror finish down to a fine art now so the black will look stunning without a doubt. The only problem is the veneer placement.
I really do like that first one in the pics posted above so I'm going to ask about something very similar if possible.
What I'll do is knock up some more CAD rendering to roughly show the veneered and black areas. I'll post my fav or favs later on.
Also regarding photo's:
I haven't got a camera that works at the moment. It got dipped whilst I was on holiday about a month ago! I'm surprised nobody asked before since I haven't posted any pictures for ages and I've been working away on these all that time.
When I've got a little cash to spare I'll get another but in the meantime its no pictures. Might treat myself to one as an early xmas present 😀

This was what I was suggested B4.
The problem I have now (esthetically) is that the woofer isn't the black supravox, but instead is the modern looking "grey'ish" seas unit. While I'd prefer the combination of wood and piano black laquer, I don't really see it with the seas unit.. sooooo - I'd stick to paints instead (because of the seas color). The alternative of course is to some how color the seas driver black or utilize a black grill cloth for it.
Now you could go for different color choices on mid/treb. unit vs. the bass unit, but frankly the design itself is quite visually complex and I think that only a monolithic paint scheme would do justice to the design (i.e. make it cohesive visually).
Furthermore I think the "fractal'esq" shape is more than suggestive of a gem stone. If it were me I'd stick to gem color (multicolor in particular to get enhance that fractal nature) that complements the drivers. Because of the grey of the seas unit and the silver of faceplate of the scanspeak, something silver to grey with naturally occuring color highlights should do the trick. The most obvious multicolor I can think of then is a diamond, where the dominate color is silver'ish. A complex graphite color might look even better because of its blend with black portion of the drivers.
This leads me to yet one other possibility (though by far the most complex). I remember once seeing (on some custom cabinets) a graphite finish with H U G E depth alternating between silver and charcol in color while still having a mirror finish. The base was a quilted maple veneer (which gave an almost "amorphous" quality to the color and its various hues). I think it was bleached first and then "multi" stained (i.e. a little applied and then wiped off until dry, repeating the process) with a silver grey like stain. Then of course a french polish finish to achieve the superb depth. I wish I had a photo of it, but alas no.
In any event I can't help but think (after seeing your finishes so far) that what ever you choose - it will look fantastic.
Scott you are deep man 😀
What about spectraflair:
Judging by the picture of fractal veneer, I fully expect a large dose of high quality clear coat would bring out a wonderful three dimensionality.
My concern is that a dark veneer and multi spectral silver finish such as the spectraflair would not gel well. One is modern and cutting edge the other of deep artistic value. It would be quite a challange to combine the two into something that look cohesive and not 'tacky' or 'misplaced'.
What are your thoughts?

What are your thoughts?
The spectra flair looks excellent for achieving the multi-color hues of a diamond. However IF you decide to go the "diamond" route, like you, I think that you should NOT do a veneer and paint scheme (which would almost certainly be "disjointed" visually), rather just paint the whole speaker the same color to achieve that cohesive look I was talking about.
To a achieve the diamond like look, I'd consider a "frosted" chrome with the spectra flair on top (and then some clear coats). A true diamond's cut clarity (even if you could mimic it) would be too obvious/garish at this size. Instead the "frosted" chrome paint finish should look similar (though more refractive) to POLISHED aluminum that has been sand blasted (..looking not unlike a natural non-cut diamond). (I suppose the best subjective description would be "diamond dust".) The chrome paint should be easy to obtain. As for the "frosting" it would be considerably better to sand/substrate blast the chrome paint (..from a distance to avoid stripping it off), BUT there is a commonly available laquer that gives you the "frosted" finish look. IF you use the frosted laquer, be sure to first build up several clear coats before applying the frosted finish. As to when the spectra flair should be applied - I'm not sure, possibly b4 or after the frosted laquer OR both. Additionally if you wanted to tint the finish to something more like black chrome you could do this in between the layers of clear coat to achieve the desired tint with depth. Of course I'd create several samples b4 deciding on the exact finish for the speakers.
Ah well, just some ideas.
edit.. I think you may have misunderstood the last paragraph on the previous post. When I said a "graphite" finish with a "base" of quilted maple I meant that the entire cabinet was finished with quilted maple veneer that had a lusterous graphite (to charcoal) color. Again, a picture is worth a thousand words.. its just to bad I don't have the picture (or anything like it..)
