Example the Dayton 15" HO driver is $50 more per driver right now. The Titanic 15" drivers are $100 more.
I will be pulling the trigger soon but I want to do this right the first time smile.gif
I have been doing a lot of reading lately and I think two 6-8 cubic ft ported boxes is the way to go.

The HO has some nice extra's like the triple shorting ring to keep inductance linear reducing distortion over cone travel. This only matters if the driver is being pushed to the edge of it's excursion. The cast basket is nice bling too. Other than that the performance will be real similar to the DVC. That's what makes the DVC such a good deal when it goes on sale.

The Titanic still has a nice cast basket, but it gives up the triple shorting ring while gaining an extra 5mm of excursion (not implying the 2 are related). My models show it to be good for an extra 3db of max SPL if you have the power. So, 2 Titanics in ported boxes run off the iNuke 6k would be capable of about 3 db more than 2 DVC's but 3db less than 4 DVC's run off an iNuke 3K.

Make sense?

It does. Seems like the DVC's with an iNuke 3 is a hell of a value....

Yeah, value is the key.

Don't get me wrong, the HO's are real nice. If you don't mind the extra $200 for 4 of them I'm sure you would be happy with them.

ack,

FYI. Guitar Center has 15% off any single item (today only) if you want to scoop up that iNuke. I actually bought a iNuke6000DSP online a few weeks back, but just brought it back to a local Guitar Center for a refund. I bought the Cerwin Vega CV-5000 today for $680 shipped.

Thanks popalock, I did look into this deal but they would not accept the 15% off coupon since the item was already discounted. But I appreciate the heads up, I would have jumped on that deal smile.gif

Try this...

Bam!

Not sure if that is a one time code, but if it is and it doesn't work for everyone then all you have to do is live chat with one of their staff and ask for the 15% off code. It takes like 45 seconds.

For sure man. I can already tell you that I am not pleased that it weighs 83lbs.

No dice on the code. Spoke to CS and they told me the item does not qualify for promotion codes because it is currently on sale.

Thanks though.

Been reading through lots of build threads the last few days... I think I could pull off an 18" driver in a ported 7-8 cubic ft enclosure as well. Obviously an 18" Dayton HO driver is more money, but would it also give me more output and extension with an iNuke 3K? Build one now, and then another later after I sell the VTF-15H?

Gah! Now that the thought is in your head you have to do it. Otherwise you will always wonder. See what you've done? wink.gif

LOL, I know.. I am just thinking out-loud. I am 100% committed to going DIY now. I have added the Dayton drivers to my cart several times but then get sucked into an 18" build thread smile.gif

If two 18" subs = 3 15" subs, well then I would prefer 18" if the enclousure is under 8 cubic ft.

I literally just got that code 15min ago.

If you seriously want this amp, PM me your phone # man and I'll walk you through how to make it happen...

I'm wondering if you wouldn't be better with the inuke6k if you are going to do 2 18 HO's. I wasn't going to say anything because I've not modeled it, but I seem to remember that they can take more power than the 600w ea you would get from the inuke3k.

I probably would.. Cost about $150 more... So I would be looking at $500 for amp and about $1100 or so for two 18" subs using the Dayton HO woofers...

If I sold the VTF-15H for $700 or so (it is not even a year old) that is pretty manageable...

I would have to buy the amp and build one sub and then build the second after I sell the VTF-15H....
post #45 of 203
they can take a lot more power, i think Gorilla has like 1200 going to each of his 4, however you dont have to run that much power into them, even with less power they model really well. I plan on running 2 in seperate 4 CUFT boxes off an EP4k

If you wanted to go with two of the HO 18's, the CV-5000 would be a great match. You would thank me 3 months down the road for not having to buy another iNuke to power the two extra 18's you will build to help address your upgraditus itch...

Dual HO 18's are very capable. However, always plan for upgrading so it's as painless as possible.

Haha, well I can tell you that I will definitely be limited to 2 7-8 cubic ft ported 18" subs. I don't really have room or WAF for more than two. So one on the front wall and one on the back wall.

Back wall is limited due to a large DVD rack that takes up a huge chuck of real estate. Front wall is limited to one sub due to 125" screen and a corner loaded fireplace. So if I am limited to two subs, 18" ported may be the way to go.

Another option would be one very large subwoofer that goes under the 125" screen. Max height would be limited to 20-22" but the length could be as long as I want. Depth would be 22-26", but I could do two large subs under the screen and another sub in the back of the room.......

Oh wow, that sounds interesting. I've never seen a dual opposed ported build. Seems like 7-8ft^3 might be small for ported.

It's funny. When I first moved into my current home last year I thought I was space limited to two subs. I did my research and found the two beefiest subs I could. Now that I've been looking at subs, such as the HO 18, I find myself thinking of creative ways to add more woofage in my life. I mean, I could have bought 4 HO 18's for the price of one of my LMS Ultras. Now all of a sudden I can picture implementing 8 subs in my current space NO PROBLEM! Heck, scratch that... I can get rid of my center channel stand and I can envision 16 subs no problem...

Yea, this does sound cool. He might be able to pull it off with a centered slot port (port on side facing forward). It would look pretty mean too. biggrin.gif

Now you're talkin' sense! 16 subs 'no problem'.

Well it took me longer to get Winisd up and running than I thought smile.gif I have no working Windows system in my home right now (Mac/Linux guy) so had to setup an open source VM player and build a Windows 7 VM. Got that done and installed Winisd Pro last night and finally have things up and running. Played around some (it was almost 2am) before I called it a night and I clearly need to read up on the software and spend some time with it.

Once I start modeling some things, I will bounce ideas off the forum to ensure I don't do something stupid. I wanted to take this DIY build as an opportunity to learn, and I feel like I am slowly coming along.

Okay, I pulled the trigger on 4 of the Dayton DVC385-88 15" drivers at $99 a pop eek.gif One of my original goals was value and once I started pricing out 18" woofers and larger amps, I realized I was probably overdoing it (not that 4 15" drivers is shabby). This is my first DIY build, and I can always upgrade later when I get the itch....

I am thinking two dual front firing subs in an 8-9 ft enclosure tuned to 18hz. Going to do some modeling in Winisd Pro and see what my options are but there were some solid recommendations in the first part of my thread using 8ft enclosures with dual 15"''s with a slotted port with one 90 degree turn. This could be the winner and one thing I am struggling with in Winisd Pro is the ports but I will keep playing with it.

So next step is deciding on the box plan and then start cutting smile.gif I loaned my table saw to a buddy and will be needing it back in the next few weeks...

Leaning towards the iNuke 3Kdsp amp for power.

ack, you have really done your homework. nice. try to sneek up the volume by a little...otherwise good plan all the way around. plopping one per corner might be a little more room mode friendly...
post #56 of 203
Just a thought on dual iNukes - when comparing to amps with no DSP (as is the case with the CV amp) then you only need the regular iNuke which is $399 & even less with some sort of sale or discount, since DSP processing is coming from somewhere else. Two iNukes would put out a grand total of 8,400 RMS watts at 4 ohms for $800 or less... 10 cents per watt.

That said, I traded my iNuke for a Crown XTi-2002 and I'm sold on that line even if the watts come at a price premium. Better SQ overall (IMO), DSP, light weight, solid quality construction, quiet fan that stays off most of the time, stable at 2 ohms... just love it! I gotta score an XTi- 6002 one of these days.

WinISD is no good for slot ports. It assumes a square port that doesn't share a wall of the cab. Use this:

I don't recommend going smaller than 9cu ft per pair, though 12 would be ideal.

The iNuke3k is ideal power for 4 of these.

I definitely want DSP. I like the look and sound of that Crown amp you own, but it might be more than I am wanting to spend at this time.

Baby steps smile.gif I think an iNuke 3KDSP will be a good starting point. I just bought a new HDTV for our family room so it is eating into my DIY budget a little...

That is extremely helpful. I don't know what I would do without you guys! I like the look of slot ports, so this is the direction I will be going. 9cu ft per pair is large, but I will see what I can do.
