Entirely up to you, but screws are cheap, and will ensure the glue doesn't crack and break away. Because eventually, it will, if that's all you use to hold it together. I have seen it too many times, when people come to me wanting a new box built for their ride... Just make sure to pre-drill your screw holes, so the wood doesn't crack.

depends on what kind of music you listen to, the rec. will be more flat down to 30-32 hertz, and the one you are planning will have about 2db's of boost at about 38 hertz, and will have less output below that...

5 cubes tuned to 28 to 30, and 60 inches of port area should do quite well with either driver.

OK, no I haven't measured them. On to the next one!

If you don't believe me, then come demo them, and that speaks for itself.

Its all about resonant frequencies, I haven't measured it personally, but I have read a lot of material explaining about it. And yes, I do like to push my gear to its limits, just to see what its capable of. I'm crazy like that.

I was given an old DHD 12" at one point that was rated for 1200 watts, I ran a 1000 watts RMS to it for 6 months, bottoming it out on a daily basis, before the VC former broke into 3 pieces and separated from the cone. That thing took a lot of torture! Aren't SSD's suspension limited so that the soft parts will give out before the coils do?

I have pushed my SSD18's to over 3 inches of excursion with no problems. I have been told by a few people that the xmech on the SSD18 is about 3.25 inches peak to peak. But it is enclosure and tuning specific. Different frequencies put varying amounts of stress on a woofer, so reaching xmech at 40 hertz is a much different monster than reaching xmech at 10 hertz.

If you run it off the sub preout on your reciever, you shouldn't need a crossover. Depending on the model of your receiver, you MIGHT (maybe, maybe not, its model dependent, it seems) need something like a Samson S-Convert to run between the sub pre-out, and the amp, if you go with the EP4000. It's a good idea to have anyway, since it also has gain matching circuitry, and you dont have to make or buy an RCA to XLR cable... There is a lot of info on the DIY Sub section over at the AVS forum about setting it all up as well. Here is a link to the Samson. I agree about the SSF, I have mine set at 10 hertz, only because I can't disable it on my amp, I highly doubt you will need it with that sub. I can't even bottom out my SSD's on subsonics with 3600 RMS to them, but it may be different with your amp, enclosure, and tuning.

Your looking at about 600 bucks an amp for 1000 watts. Also, they are only stable to 4 ohm, so keep that in mind when deciding your wiring options. A pro amp might be a better option for you.

My guess, they will be built when they are built, right? Or when you are damn good and ready? Just had to throw that out there, haha. I am excited to get them, though!

Either build a new box that is around 4-5 cubes after driver and port displacements, and has about 60 inches of port area for that size box, with a low tune (26-32 hertz), or go with a BL 18 or an XCON 18. Enclosure design and building is fun, once you get the hang of it.

its all dependent of your listening tastes, the size, Q, and tune of the enclosure, and how knob happy you get, and whether you can hear when the subs are being pushed too hard, or when power compression starts to kick in. I run 3600 RMS to my SSDs, but I have my gains set so that i will never give them a clipped signal, and I can hear when they are being pushed too hard.

I agree with Scott, I have mine in 13.5 cubes (6.75 in seperate chambers) at 26 hertz, and it is wicked! The response peaks at around 45 hertz, though, due to airspace limitations, but overall, it digs very deep. Even in the mid teens I can knock stuff off my shelves and counters in my house (and my neighbors' houses) with ease.

trust me there is nothing cheap about these subs, other than the awesome price tag.

Useful advice!!! What type of amp do you use to push your subs? Its listed in my signature. I don't think everybody is down to run car amps in their home, but I have my amp running off a power converter and battery bank. I really need at least 4 batteries when I am drawing that much juice though. I only have two right now. Until I can drive again, I make it work out alright, my neighbors dont like me sometimes when I get a bit volume happy, though. I have had a guy 3 blocks away say that I was rattling his windows in his house.

I run 1800 RMS to each of my SSD's, and they still surprise me every time I listen to them. I just cant afford to keep replacing light bulbs and the dishes I keep breaking from the bass.

Well thank you again Nick and Scott, I just bought a pair of the 12's. Happy Thanksgiving guys! Whats the build time gonna be like on these?

good luck bud, I wish I had the cash to buy two of the xcon 18's for myself right now, and sell the ssd's. but I don't, so I ended up buying a pair of fi black friday 12's. I love bass way too much, I already have entire rooms full of stereo gear, and yet I just bought two more subs, haha. damn- when are the 22's coming already? I want a pair right naow!

It will handle it if the gains are set properly, I have run my ruby at 2500 rms to one of my ssd18's in 6.75 at 26 hertz and it just cant get enough. The xcons are even beefier, so I dont see why it wouldnt handle it, as long as it was in a properly built and sized enclosure. the bigger the box, the less power a sub will be able to handle, so keep that in mind as well. About 6 to 7 cubes for ported and tuned low 30s/high 20s should do real nicely with that setup...Amp headroom is never a bad thing, my friend.
