So I got my MJ-18's running...

And they are some nice subs, especially for the money. I have two in a shared 9ft^3 box tuned to 33hz with 140in^2 of port.

The first impressions I had were full of surprise. The magnet on this is much larger than it appears on the mach 5 site. The build quality is very good as well. There is no extra glue anywhere, and everything looks seamless in construction. The sub looks great; I love a simple all-black subwoofer //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

In the box I am using them in, they have a nice upper roll-off at around 65-70hz, which works well with my RS180 mids. I really don't even need to use a crossover, but I still do at 63hz at 24db/oct. The upper end is very accurate and well-pronounced. The MJ-18 doesn't get sloppy when quick basslines in the 50-70hz range are thrown at it. The low-end on these is absolutely beautiful. Loud, accurate, and smooth are the three words that come to mind when playing below 45hz. You absolutely can't believe that these things cost just a little under $120+ship a piece...even though I got my pair on sale for $198 shipped.

All in all you cannot be disappointed by the MJ18, so long as you know what you're buying. It's not an spl monster, but It's a **** good sounding woofer, very accurate even in a ported box, and is the best bang for buck sub that I have ever heard.

Sorry, I'll let to continuous "what sub should I buy," "what sub is the best," and "what is the loudest sub" thread continue to reign supreme.

Grats on the MJs. Beautiful sounding moofers. I miss mine //content.invisioncic.com/y282845/emoticons/crying.gif.ec0ebefe590df0251476573bc49e46d8.gif

They're definitely more than what I was expecting. This woofer handles everything well. It has some issues producing a continuous low bassline with higher "punches" thrown in, but other than that it's a good woofer.

What did you end up getting after you got rid of yours?

9 cubes big enough for both??? I want to try some, but giving up my whole back seat again is out of the question!

I have 2 MB Quart RWE-354s. Great subs, too. Wonderful SQ. You should try sealing up the MJ's. I sealed mine up and the SQ was superb. I would probably still be rockin my MJ, but it got stolen //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Mach 5 suggests 4.5 for each...I asked Mark through PM if it would be enough, and he said it'd be perfect for two of them. They sound great, and low-end is definitely not lacking.

Meh, nothing special about vids IMO...you see one sub excurting and shaking things, you've seen them all. My intent was purely to inform people about a solid sub that's affordable to nearly everybody on here...not to mention my camera stopped working for no apparent reason a couple of weeks ago.

Oh yeah, I read your review this morning, glad you're happy with them...I was going to seal up 3 of the MJ's, but decided to port 2 instead. I'll be hitting some comps just for fun this season, and will have ~1800 available for the pair (only running 750 to the pair right now), so it should be fun.

My brother is very pleased with his, and i cant blame him. It realy is a great sub for the money. He went to a USACI show 2 days ago and was able to do 144.1 at the kick at 42hz. So they can get decently loud with little power.

Glad you are happy with them.

^^^ man 144.1! not bad, I'm thinking about doing a 37~40 hz box just b/c my amp will not play low it is loud all the way down to about 40/35hz so why have a box tuned to 31hz if I cant get low ind out of my amp

OP, has your sub broken in yet. Heard that once those are broken in they will perform even better //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

That's a tiny box for 18's. The box I just built for my two 15's is bigger than that. lol

Glad you like your new toys.
