Forevrbumpn Posted August 20, 2008 Author Report Share Posted August 20, 2008 Ive done Mojo 12s at 34hz many times, that was the old Fs, but 45? is it the quad coil Mojo? and if its a quad coil, what are you looking to get out of the sub box combo? spl? sq? nd ofcourse, what kind of car I have a ritual called "terminator". I crouch in the shower in the "naked terminator" pose. With eyes closed I crouch for a minute and visualize either Arnie or the guy from the 2nd movie. I then start to hum the T2 theme. Slowly I rise to a standing position and open my eyes. It helps me get through my day. The only problem is if the shower curtain sticks to my terminator leg. It sorta ruins the fantasy.

jhmeg2 Posted August 20, 2008 Report Share Posted August 20, 2008 Its a dual 2 running @ 1 ohm off of a big bell. Its in a trailblazer, mostly for a Q setup but I like to beat it up a little. ////Alpine, Eclipse, Load Boss, Pheonix Gold, MB Quart,Digital Desings, Memphis, Stinger, Periphial, MTX, Visualogic Link to comment Share on other sites More sharing options...
Forevrbumpn Posted August 20, 2008 Author Report Share Posted August 20, 2008 Man, Ive had the Belle1300 on a mojo 12" before, and 2- 15s The bell would work perfect for daily listening, since its the DVC 2ohm you just PMed me, I know it will be fine if you tune it down to 36-38hz, That 45hz has got to be right out the box with NO break in period, because the dvc 2ohm mojos are the triple spider design, not the 4 spider, quad coil deign once that sub is broken it, it will be fine around those numbers, 36-38 And even though tuned a little higher than normal, the Mojo, even tho a SPL sub, will play lower than Fs due to its low Qts design (low Qts for a SPL woofer) You should be fine, it will drop alot lower in car response than the 36-38hz tuning I have a ritual called "terminator".

jhmeg2 Posted August 20, 2008 Report Share Posted August 20, 2008 when I say 30 Hz... I mean 30!!! Not 30 ish is that to low. I have an MTX 4500 8" tuned @ 39Hz and it peaks at 48Hz. 4ohm with 100 watts doing 134.9 in an envoy (same as trailblazer), so I thought if I tune the MOJO to 30 Hz it would play at like 39-40 ish... I just don't wanna launch the coil and smoke it ya know. ////Alpine, Eclipse, Load Boss, Pheonix Gold, MB Quart,Digital Desings, Memphis, Stinger, Periphial, MTX, Visualogic Link to comment Share on other sites More sharing options...
Forevrbumpn Posted August 20, 2008 Author Report Share Posted August 20, 2008 optimum tuning for quarterwave is all based on the subwoofers specifications, mainly its natural sonance, wich out of the box is 45hz, but after break in will be about 36-38hz only other way to get it closest to 30hz is with some sort of bass eq that will bring the gain up a little bit at or close to 30hz It can some what bypass the subs Fs, if done right on a RTA, you may even to get it pretty flat from 30-38hz but again, in car response- TRANSFER function, will get the truck booming alot lower than the tuning point, but again will peak higher than tuning so from tuning to 20hz it may be pretty flat, but from tuning to maybe 55hz or so, you may see some 3-6db peak if you want to go lower than 30 flat, and peak closer to 30 well, you are going to have to get 1) much bigger woofer, a 18" atleast 2) a huge tline, or ported box tuned lower than 30hz 3) more power I have a ritual called "terminator".

jhmeg2 Posted August 20, 2008 Report Share Posted August 20, 2008 hmmm, well. I have an Alpine PXA-H701 in the truck, and a Audiocontrol 3051 on the self to tune with, the get an 18" part, not gonna work cause I still need to carry golf clubs in there lol. I don't need it to peak at 30Hz, I'm just asking if building the enclosure tuned to 30Hz will hurt it. Thanks for the help. ////Alpine, Eclipse, Load Boss, Pheonix Gold, MB Quart,Digital Desings, Memphis, Stinger, Periphial, MTX, Visualogic Link to comment Share on other sites More sharing options...
