What do the DIY pro's say

Im in the process of shopping around for some new subwoofer(s). Im debating a pair of SVS PB-2000 for my basement theater due to the fact that the theater isn't separate from the rest of the basement, and the basement as a whole is a good 800 sq. ft.


During my search however I did find a pair of monster 18" DIY subs on CL and I was curious as to what the crowd here thinks of the set up/build.


The ad states:


2 Custom made home theater subwoofers...

10 cubic foot ported enclosures tuned to 17 hertz
3cm granite tops
Internally braced
1" MDF material
Front baffle is 1.75" thick
Speakon Neutrik connectors
18" Stereo Integrity drivers
Duratex speaker enclosure coating
Down firing sloted ports
Adjustable metal feet
22" w 42.5" h 25.5" d
around 240lbs each


Additional info from the seller (who seems very educated on the topic):


Behringer iNuke 3000DSP
Large slot ports that are downfiring
Neutrik connectors
Subsonic filter as protection from over excursion


Seller wants 2G's...


What say you, subwoofer enthusiasts?

seems a little steep to me for SI drivers and an inuke 3000.

I have a mini marty with a ultimax 18 and a parts express flat pack with an ultimax 18 with a inuke 6000 dsp. both finished with duratex. I have a little over 900$ into it.

so it being another 1000$ seems a bit steep to me

I also agree, I think I am about 1500 in for my pair and amp.

Unless the cabinets are mint, I would haggle a lot.

Unfortunately DIY doesn't add value but you get a Big Bang for the buck!

The cabinets look nice from the photos. They have a granite slab on the top but I don't think that should add actual value to the pair. They are 2 separate cabinets in case that wasn't clear.


The main reason I was asking is because there is a DT Trinity for sale in my area for $2K as well...From what Ive read I assumed that DIY stuff should go for a bit less than factory manufactured flag ship speakers.

depends on which SI 18 drivers they are. could be a good deal if they are the $750 drivers.

if they are the under $200 drivers I wouldnt pay more than $1000

If they are the HST-18 driver then it would be a good deal but 1 3000dsp is not nearly enough power to drive a pair of those.

That's also what I noticed...Everyone with DIY projects like this runs something comparable to a 6000dsp.

Those are the Regular SI-18 HT that was $169 each.. Not the HST-18's.. $2000 is waaaay too much. It does look nice with the granite .. But not worth it IMO. $2000 would get you better DIY subs. It depends on how much you value the product. Most of us posting disagree with the price. I think it should be Max 1200.

If you KRANK it.. They will Listen..

Yes if they are the regular SI-18 then that is way to high on price. Granite is expensive but that does not really add to resale value of a diy project. That is like doing performance mods to a car and trying to tack it on the resale value. Does not work that way.

For that price you could buy 2 nu6kDSP's and 4 UM-18 flatpacks and have way better bass. The boxes would be uglier though...

A NU3000DSP is $280 shipped, when new.
For two HT-18's, that's like maybe another $4-600, when new.
Speakon is only $20, at the most.

So he is saying the box is worth ~$1200.

Even if it was veneered birch plywood, that's still only worth $400 max... when new.
If it is duratex MDF, then that's only worth $200, max.

Unless he used actual wood(not ply or MDF), or veneered it with real carbon fiber, there is just no way to make a box that expensive.

Granite is nice, but it doesn't increase the SPL or sound quality.


Granite counter tops are nice, but it won't turn a crack shack into a trump palace.
To be honest, the HT-18 and nu3kDSP are entry-level DIY.

That said, even entry-level DIY will spank a SVS PB-2000, so do keep that in mind.

Seller says the subs are SI 18-HTD2. I cannot find the exact model on SI's website...


Perhaps its the HT-18D2? Ether way, the internet tells me that this is roughly a $190 sub woofer. Which also tells me this price is much, much higher than it needs to be.

thats one of the cheap ones. It sounds like a good sub. ie 1" mdf ,speakon etc but normally something like this would sell for around 250-400 per box and maybe 150 for the amp.

He offered to come down to $1800 but now that I know they aren't the $750 sub woofers I honestly think I should pass on the deal. For $2K I can get a huge amp (or 2) AND better subs AND build my own boxes, happily.

if you can build your own boxes you can get about the same output for less than a thou easy.

two rss460s at $251 each with a $10 coupon. Inuke 6000 for $329. $100 in mdf and some glue and paint and you are smooth sailing.

Im crafty enough to build my own boxes for sure. Im still getting educated on the world of amps.


Should I just get some subs and a 6000 and let 'er buck?

Any suggestions for type of wood, bracing, adhesive, etc...? Or is there a good sticky for that somewhere?


Also, any suggestions for what NOT to do?

MDF is most common

bracing you can do sticks but window works better (cost more and a little more time consuming but better)

tight bond wood glue

I'd highly recommend using PL Premium, not tight bond. PL will hold much better, it also expands to fill gaps. Even using MDF, that is CNCed....use PL Premium. There's no reason to skimp on keeping your cab together. A bonus, a Brad nailer will not only help in putting it together faster, but will help hold it together better. Win win.

I was planning on nail gun + adhesive for sure. I figured overkill wouldn't hurt.


Time to get back to more researching. Id imagine there are templates and suggested design sizes and styles around here somewhere as well.

Overkill never hurts. I'm hoping by nail gun you're referring to a Brad nailer. Don't want to use an actual nail gun.

As for templates, I'd check out the DIY area. But, it sounds like you're wanting to build a pretty basic box. Won't be too hard.

I havnt not heard of anyone using that while I was doing my research ...not saying its not good, I just didnt see it.

I used tightbond 3...and used alot of it based on what others did and nobody said anything negative about it.

time will tell how long the boxes hold up.

but the more info the better.

Bringing this one back around....


These pair of subs are still for sale. Any spare time I have needs to be spent working on my house (not driver cabinets ) so I contacted the seller again to see if he had wiggle room on his price. I found out he has some other gear he is looking to part with as well.


After some emailing back and forth he offered me the pair of subs, the iNuke3000DSP, a XPA-5 (still waiting to find out which gen. it is) for $2200. He sent me some pics of the build and the cabinets are definitely heavy duty and built properly with dowels, sealant etc.


Im thinking Id need another iNuke 3000DSP or just a single 6000DSP for this pair or subs so Im a little hesitant to pull the trigger.




Id love further input from you fellas...

You don't NEED to upgrade the amp, but you'd be amp limited.

I'm sure they'd still put out really good bass.

Unless you just absolutely love the boxes, it seems high to me. I guess it also depends what you value your time at.

As stated above, if you bought these brand new today.....
Inuke 3000dsp - $280
2 x SI HT18 - $320 ($160 each)

You could also get:
DIY Soundgroup flatpack 150.00x2(300.00)
Inuke 6000dsp - $360-$395
2 x SI HT18 - $320 ($160 each)
Various fasteners,glue, cables,connectors,stain,varnish and or paint, Durtex 100.00-120.00

The flatpack go together very easily.The finishing can take a little while to do depending on how you decide.
That would save you quite a bit of money and with the Inuke 6000dsp give you more power as well.
