mrogowski 6 Posted July 20, 2006 Hi everyone,If you are interested in seeing some test measurements of the MJ-18, you can go to the web link below. I took some frequency response curves and in-car SPL measurements.http://testbed.mach5audio.comBest regards,Mark 0 Share this post Link to post Share on other sites
flakko 1 Posted July 20, 2006 dang. thats pretty good for a 350w driver o_O 0 Share this post Link to post Share on other sites

Adrian_D 520 Posted July 20, 2006 (edited) The MJ-18i meant the 12 with the cast basket and bad-ass looking motor. Edited July 20, 2006 by Adrian_D 0 Share this post Link to post Share on other sites
mrogowski 6 Posted July 20, 2006 The MJ-18<{POST_SNAPBACK}>i meant the 12 with the cast basket and bad-ass looking motor.<{POST_SNAPBACK}>That's an 'as yet unnamed' prototype sample that came in with one of the orders. looks interesting doesn't it? I'll post more info on it when I get the chance...Best regards,Mark 0 Share this post Link to post Share on other sites

djjdnap 78 Posted July 20, 2006 i thought it was 600rms? 0 Share this post Link to post Share on other sites
flakko 1 Posted July 20, 2006 wow teh motor is taller than the basket lol 0 Share this post Link to post Share on other sites
Adrian_D 520 Posted July 21, 2006 wow teh motor is taller than the basket lolkinda looks like a blueprint sub, except it only has double stacked magnets. i want one ! the mj-18 is 600wrms. 0 Share this post Link to post Share on other sites

Is that a brand?They were definitely thinking underhung when they came up with this design. I calculated Xmax at 11mm given its voice coil length. If they had low distortion in mind, I'm sure they achived it with this unit...Best regards,Mark 0 Share this post Link to post Share on other sites

djjdnap 78 Posted July 22, 2006 y does everyone keep sayin 350rms then?on the main web site is says 600rms though.does it only come in 8 ohms? 0 Share this post Link to post Share on other sites
mrogowski 6 Posted July 24, 2006 Hi dj,Currently, it is only available in 8 Ohms. If there is enough interest / commitment, I will get a run of 4 Ohm units.You're right, the blueprints sure look similar.Best regards,Mark 0 Share this post Link to post Share on other sites
Aaron Clinton 2,372 Posted July 24, 2006 Mark,I am not sure if you have seen them before, but Group Buys have been successful in the past. It is a win win for both parties. The company (ie YOU) gets to move a large number of units at once, and the buyer gets a good product at a little discount. You don't have to just an idea.Also sqeak, a member here tried very hard to get a short run 18" model for the members here at SSA, but due to the cost from Adire, he was not able to do the minimum order. Maybe he might want to see about doing it with your 18. 0 Share this post Link to post Share on other sites
djjdnap 78 Posted July 24, 2006 ^^ I like ur thinking.Because i'll def buy some of the 18'sI just dont like the 8 ohm thing but i think 4 ohms would be perfect for my amp.. 8 in series is 4, so yea, that may work out..I'll keep my ear to this GB idea 1st though , lol 0 Share this post Link to post Share on other sites
mrogowski 6 Posted July 24, 2006 Yeah, a group buy would certainly be an option. If I can move these things before they take up permanent residence I'd be a happy DIYer.I received some prelimiary data on the proposed 15" unit to finish off the MAW line. Tell me what you guys think:MAW-15Fs = 24.6HzRe = 4 Ohm (both coils connected in series)Qms = 5.06Qes = 0.35Qts = 0.33Rms = 7.2kg/sCms = 0.18mm/NMms = 236.7grBl = 20.4SPL = 90.9 (geez why not just say 91)VAS = 190LLe = 2.41mH 0 Share this post Link to post Share on other sites
Adrian_D 520 Posted July 24, 2006 nice looking fs, strong motor, good efficiency. i want one. pics ? 0 Share this post Link to post Share on other sites
mrogowski 6 Posted July 24, 2006 Like the 12's... only bigger I'll shoot a picture up in the coming days...m 0 Share this post Link to post Share on other sites

Perhaps I can help...http://www.soundsolutionsaudio.com/forum/i...wtopic=4820&hl=Everything's in that thread....T/S specs, Bl & Kms curves as well as the motor design that would have been used and pics of what it would have looked like. Pretty much everything was done but having the proto built.....I really think that would have been one sweet IB driver. 0 Share this post Link to post Share on other sites
