Hi all,
Although i've been a musician, DJ and studio engineer for years, i reciently was forced to build my own PA subwoofers for a gig I was working after the ones i had ordered fell through last minute. I was forced to learn, reserch, design and build them all in about 4 days, and built some basic reflex cabs with Kilomax 18" in them. Although they were ok and got me through the night, they were too rushed and i wasn't brilliantly happy with the sound, but the last few weeks of reserch and reading at a more relaxed pace has finally led me to this fantastic site. Initially i'm gonna have a go at making a couple of X1's to replace my own efforts, but long trerm i'm gonna do a full system. I plan to get them coated in a spray-on textured paint as used by these guys www.loudspeakerbuilder.com (and truck drivers round the world! ) but as its a specialised application i have to take it to them and let them do it. I can get a discount if i do them all at once (and saves on having to drive several times!) so i'm gonna build a full system worth of cabinates just now, then add the drivers and finish them off in the future as time/money permits. Anyway in order to plan ahead and build the cabs my question is whats best to go above them? With the top end of the X1 crossing over at 80-120Hz the tops have to go fairly low, so i was looking at the X15, as sugested in another thread. Also I take it the X definition (X1 and X15) may mean they're designed to complement each other? Will this be enough to cover the whole sound spectrum? I'm also thinking of building some HD-15's long term to run with them also, firstly would they sit well with the X1 (one being a horn and one not)? Secondly If i did build the HD-15's, would the 15" in both the HD's and the X15's work well together, or would i get a better sound over the complete system if I instead built some x12's or x10's to go with both the X1 and the HD-15's?. Lastly (and i realise i'm going on a bit!! ) what ratio of cabinates would give an overall balanced sound. One X1 to X15 (or multiples of) on each side or 2:1 or whatever. And also what if i put in the HD-15's, 1:1:1 or whatever? Thanks everyone for any help. (and thanks to Rog for such a helpfull site in the first place, if only i had found it a couple of weeks ago!! ) Kev |

Hi Kev, Welcome to the speakerplans.com forum. The X1 / X15 combination works very nicely (heard it myself), and gives a nice warm sound across the range. A ratio of one X1 to one X15 would be fine for most types of music except for heavy dance / techno. The HD15s are designed to be used in big stacks for heavy dance music / techno, so if you needed more output, you would be best to just build more X1s and X15s. Also, don't use the Kilomax in the X1. The X1 is a 6th order bandpass design, and this type of cabinet requires a driver with a strong motor system, which the Kilomax doesn't have. Hope this helps, Jamie |

I run X15's, HD15's and a different dual 18 6th order bandpass sub. The X15's go well over a single sub but 2 is better. There is certainly less punch when not using the HD15's howver its still pretty impressive. My subs play well up to 120hz and more so i can use them higher than you'd be able to with the X1. I'm glad i went for the HD15's over more subs as they just sound incredible, really tight and punchy and very exciting to listen to. Big grins all round I use a ratio of 2 subs to 6 HD15's to 2 X15's powered with 3k on subs, 3.5k on HD15's, 1400w on X15 mids and 350w on the tops. |

Just one point to clarify; If you decide to build both the X1 and HD15, don't use both on the same frequency range, use the X1 for sub (ie <80Hz) and the HD15 for low mids (80Hz to 180Hz). If you overlap the frequency ranges the sound will become 'muddied'. Good luck in the building and remember to take pics and get them on the projects page! Matt |

Thanks for all your replies
Tink i've pretty much decided on building 2 X1's and 2 X15's per side for now, for my 'indoor' rig. Was also planning to change the dimentions a little (keeping total volume and port area the same of course), to help with stacking and transport, and after seing the great results Dom got in another thread then i'm deffo gonna look at this. Will be sure to take plenty of pic's and put the results up for everyone. I'd also love to get in contact with anyone who opperates any of these DIY rigs here in Scotland. I'd love to get along to a gig if anyone's running one, With LoonyBins/1850's or Punnishers as well as X1's. Also, i understood about the Kilomaxes. Unless anyone can sugest another design that they'd work well in (apart from a 400+ litre cab that bassbox pro suggests!! ) the think they're an EBay job. kev |

Why not contact Dom and get the dimensions off him as his mods seemed to have worked very well. At least his is now proven, it might be better than experimenting and getting it wrong yourself

Use the Kilomax in the C sub. It will tear to pieces in the X1.

@ ToXiC, and you know this how? The Kilomax would be very nice in a
home theatre methinks, but then tune the bottom port to 20Hz or the
same iwth a Bass-Reflex (with EQ and a huge enclosure like a coffee
table of course)

So does mounting the baffle flat rather at an angle impart magical properties on a driver? How is a csub different from an X1??? |

No I meant the C-sub. And Rog even said on the plans it's suitable for that design, so the C sub must be fairly different than the X1. |
