Posted April 12, 200916 yr I dont know if i'm askin this too early but since they are available now, what is the box requirements for all XCONs?Also, what is recommended tuning?
April 12, 200916 yr A tad larger than the recommended box size for the ICON's. And tune around 30-34hz. The sweet spot on the ICON's is at 31hz.
April 12, 200916 yr Author hmm, getting interesting.I'm really interested in the 18s. ICONs do not come in 18s so this is all the possible boxes i have chosen for them-13.2 cubes NET tuned to 35hz Port area= 158sqin13.0 cubes NET tuned to 34hz Port area= 158sqin12.8 cubes NET tuned to 33hz Port area= 158sqin13.0 cubes NET tuned to 32hz Port area= 144sqin13.0 cubes NET tuned to 31hz Port area= 138sqin13.0 cubes NET tuned to 30hz Port area= 131sqinAre any of these box sizes optimal or recommended for 2 Xcon 18s?

I would say 33hz for a daily driver. But I dont know haw many cubes
April 12, 200916 yr Author well i already do a 146.8 @34hz with just 2 12s and 4,400w of power, i'm hoping i can break a 150 at a low frequency with these babies if my volume is large enough.
April 12, 200916 yr If you keep the box BIG you should be able to. SSA has definitely done lots of things right. I'd say they are one of the best subs on the market if not the best. I am dieing to hear the Xcons. The Dcons sounded way better than I ever expected so the Xcons should be unreal......... I cant wait for Thumpper to get is system done..... I wonder if he'll split the cost of some hearing ads for me after he defines me lol Edited April 12, 200916 yr by efxtruck
April 12, 200916 yr 13.0 cubes NET tuned to 31hz Port area= 138sqinThis one seem's good.Iv'e got a pair of xcon 18's sitting in my room now, just waiting for an ampIm gonna try to get 13cubes @ 30Hz.
April 12, 200916 yr Author Sweet man!When u think u gonna have yours done and ready to listen to?I'm aimin around june or july to be done as long as I get my other gear sold.The box I'm using is gonna be sub and port forward. Any excess volume around the front baffle will be sealed off to try and get as little volume to pressurize as possible.Port flowing in between 2 front seats, 26.25" high x 5" wide according to ur recommendation.I'll be running 2 2200w amps on mine
April 12, 200916 yr Im hoping before the summer ends.But there's no telling.Im debating on either a sundown3500D or an aq3500D.Your running the 2200's right?
April 12, 200916 yr I'll be running side by side common chambers with 7.0cf3 eachside plus displacement with my 15's....talking about a FLAT RESPONSE WOW!!!!!
April 12, 200916 yr Author Hmm, that may not be good for me.If it takes 7 cubes per 15 just to get flat, then it definitely sounds like the 18s need way more because I don't want my ported box peakin 10hz+ above tuning because my volume is too low.

April 13, 200916 yr here is a graph for a pair of 18" Xcons with 20 cubes... LMAO......talking about FLAT

April 13, 200916 yr Author Could you explain to me what exactly the Transfer function magnitude tells us?normally, the designs i have done for myself, the graph is always peaking well above 0db right after tuning.The current build i have- 2 AQ HDC3 12s in a 3.8cuft box @38hz-graph goes to +1db peak at 39hz but suddenly rolls off to -3 at 59hz.graph shows -3 below tuning at 34.5hz.The overall listening experience between 30-60hz sounds fantastic. Anything higher than 60hz is pretty weak. Anything below 30hz is almost inaudible. So, with that given, what does Transfer function magnitude tell me and everyone else?
April 13, 200916 yr Author here is what i got-Explain to me what this means if i choose to go with 1 of these 2 designs-13.0 cubes NET tuned to 36hz - 13.0 cubes NET tuned to 30hz -
April 13, 200916 yr Admin We will have the Xcon page updated soon. The 1st of those last two graphs will yield a sizable bump in output, or peak around what looks to be the 46/47hz area. The second graph with the slightly lower tuning still has the same frequency peak, but much less pronounced. If you want a more ground-pounder type of install the 1st would be the choice, or a flatter more daily type would be the second. Are you able to go a little larger in displacement? Also where is your LPF set at? If you don't have the room to go larger and don't mind the peak, the 18's will seriously get it done, but if you can't go larger and want a very flat response like Trevor illustrated above, maybe consider the 15's.
April 13, 200916 yr Author ok, thanks. It all makes sense now, hehe.These are some very interesting subwoofers.
June 1, 200916 yr What program is that?It look's like Term-PAK Enclosure Design but not sureYep it's Term-Pak..The same graphing I got slammed onin another thread for posting..
