I decided to humor myself and see if I could find a pic of my first subwoofer. I tried long ago, with no luck, but today I finally found it! This prompted me to dig up pics of all the subs I have built over the years. For your humor...:

I built a stereo pair of these. Sealed small 10" ACI SV10's powered by kiega amps. These were built back in 2000.


Then I got the urge to build something big. big is relative. Back in the days, this was pretty good size (now, it's almost tiny!)
Dual opposed sealed 15" sono sub using the BPD1503 drivers. Powered by a crown K2 and used a linkwitz transform.


But those itty bitty monitors really needed something to pair with better, so I built something else. These are also sealed 10", but you'll never find the drivers. These were custom ones made long ago by BPD. They were nifty long throw XBL^2 drivers designed to play low, sealed.


And as with all upgrade bugs, I decided to build a 2.1 system. The 2.0 part played to 40hz just fine, but when I watched a movie, I wanted something more gutwrenching, so I built a 24" cube using the Tumult, and a pair of Stryke 18PRs, tuned to 18hz. I don't think my neighbors in this apartment liked me too much :P


Soon, this will all go away. New SEOS-10 system with new subs will be built and thumping away in a few months. Hope to have something fun to post when that time comes!
(continually playing with ideas. We'll find out for sure if I end up with a single monster sub, or a pair of more modest subs used as stands)

I remember nearly all of these builds. Nice to see you around again, Anthony.

Nice system looks pretty slick! What kind of drivers do you have in mind?

Hey Scott :-D Glad to be able to do this again. I stopped this HT stuff years and years ago when I couldn't afford to upgrade to anything that would have a sizable improvement. Likewise, I lost access to all the woodworking tools I was using, when I moved. But now, I'm slowly getting my own tools and can afford the upgrades.

Not set yet on the drivers. This will be a HT only system. zero music (I have my usher 2-ways for music in another room). Right now, I am holding off to see who pairs what 10" driver with the seos-10. Tux already has his Eminence Delta-10A kits in the works. I'm sure we will see others. I don't want to pay the price premium for a AE TD-10M, so seeing if there is a good in-between system developed. B&C, Beyma and FaitalPRO all could be a possibility, but since I don't have the XO skills, I leave this in the hands of others. On the sub end, I have a small ish room. So this means no coffin/fridge size subs. Since the seos-10 TMs will need stands, I was thinking of doing sub stands. Still need to do more modeling, but either the ultimax sealed and EQ'd (15"?) or the titanic MK4 (ported). Not too worried about the <20hz content. >20hz is fine for me :-D

I've been plugging away the sims with 12 and 15" drivers, sealed and ported up to 3.5 cuft.
So far, I am digging ported. I'll be following the suggestion of another and worry about doing >20hz well and not worry about the subharmonics.
I've so far only modeled the Dayton Titanics, ultimaxes and SDX12.

Are there other 12" drivers that work well ported in ~3cuft that I should consider? I'm finding tons of threads on 18" builds but not much on 12"s for driver ideas :P

i can tell you im not a pro at this, but since you have a budget what about using a cheaper driver like the infinity Reference 1260w or 1262w and building multiples of them, they work greatin around 4 cu ft ported enclosures

I'd stick with 18's or 15's and forget the 12's unless you have a huge space/money constraint.

Given that I'll have a pair of 3 - 3.5 cuft enclosures, it seemed like I was better off with a 12 ported vs 15 sealed. The room is only ~ 1500cuft. Right now, I have a single tumult/PR system and I don't get anywhere near xmax.
In light of that, do you still suggest 15/18s?

With 3cuft boxes. I'd go with the Ultimax15 sealed.

Take a look at the 12 MK4 in 4cf. if you're inclined.

So I decided to play the model/EQ game with WinISD Pro (a little buggy, but nice to do these things). I modeled the Ultimax 15 sealed in 3.5 cuft vs Titanic VI 12 in 3cuft (after vent displacement, these are probably about the same size boxes, so fair game).

I'll be powering with an inuke NU6000DSP, so I can tweak the native HPF with a shelf filter, use an equal Q LT filter on winISD to simulate a shelf filter on the sealed for added extension, add in inductance of the drivers, the 50hz LP filter, and some PEQ gains. I also tossed in a static gain with the titanic to get these closer in response.

SPW with 100watts nominal (before EQ) applied.


Cone excursion


Amplifier power


EQ




The numbers seem to indicate that the sealed 15 is in fact the better option. Sure, it'll cost some power, but nothing crazy and well within the amp/driver limits. The real limit in both cases is actually xmax.
With room gain and 2 subs, I think this is the option I'll be modelling up now in Rhino smile.gif

Is that a Lambda Acoustics 10" on the floor? I think I bought that from you years ago.

That is quite possible! I've had so many toys over the years :-D All I think I remember on that driver, was that it was a 10" and designed for sealed. Maybe SB10 or something like that for the name. All that info was in an old email account that got hacked and I let die (Hotmail wouldn't let me recover it).
If it was mine, I hope it served you well smile.gif

Take a look at the iNuke's dynamic EQ function. Very cool...

12MK4. What about the 12 SDX you brought up with a couple PR’s in 2.6cf after displacement. http://creativesound.ca/details.php?model=APR12 albeit the cost of PR’s

Well, I have two things against that. 1) cost. I'd need 4xPRs plus 2x drivers, setting me back $900 + shipping. At that price, I might as well consider putting the L/R on stands and build a single TC Sounds LMS Ultra 5400. 2) I find the CSS PRs to be very ugly :P Right now, I use PRs on my sub and the Stryke/AE ones look far better (just hard to get a hold of and I think more costly). I do appreciate the idea though, but dont think this the SDX+PR is a good option for me.

12SDX/PR's biggrin.gif I run that option in my bedroom and really like it. Ok mmmmm.. looking like 15" sealed is raising it's head.

well, a pair of SI18's are now built. The Tumult/18PR needs to be retired (so sad :P). I squeezed the SI18's into the room to give them a whirl. I'm impressed.
Now I need to finish building the 1099s, get a new TV, finish building the equipment rack and... does it ever end?

That wood on the subwoofer in the far corner is amazingly pretty. Is there a build thread on that particular unit, or can you talk about the procedure you used on the finishing construction? Is it black duratex paint that you used accented with wood trim, or something else?

Ag,

Very nice projects!

I love seeing stuff from the past.

eydsamoht, thanks. No real build thread. The black is actually spray on truckbed liner. The base box is a 22" cube with 3x double thick baffles (driver/2xPR). the wood accent legs are solid joined walnut. The top is 1/8" resawn walnut. I do have some other lpics here
