Over the past few years I have been slowly building a dedicated theater room. I'm getting to the point where I'm wrapping up trim and starting to paint it. I still need to paint the front wall, pick a color for the room and order carpet. My room will be packed with 8 power recliners, which have been ordered. I currently have an older Klipsch Reference system (RS-3, RC-3, and 4 RS-52ii) and the original SVS PC -Ultra (12") cyclinder sub.

My plan is to ditch the SVS sub for dual Marty boxes outfitted with Mach-5 UXL-18's powered by iNuke6000DSP amp. Many thanks to LDT02, Blah450, for getting me started. My room is about 14.5'x7.8'x18'.

See pics below, just some quick iPhone shots during construction to get an idea of my space. I’ll have a lot of questions when I get to the amp set up but I’ll save that for later (mixing pro-audio with consumer grade HT gear)

Monkey Man, your room looks great! and has very similar dimensions to my room. It's funny I was also going to do a sealed sub build too until talking with LTD02. I've now change my mind to a ported design also after John's suggestion. My build will be a little bigger then yours, but I'm also hiding my behind a false wall/AT screen setup.

http://www.avsforum.com/t/1506201/unnamed-sub-build

I was also considering using the SI 18's, one suggestion I would make is to consider sending a little more upfront on the drivers. Take a look at the UXL-18's, I think they're a better more robust driver and would better handle the power of the inuke 6000 amp, which is also the same amp I'm going to use to power mine.
It would take three SI 18's to equal the output of two UXL-18's too.

Nice! Thanks for the sugestion, I'll take a look at that sub. I have a few major errors with my build, one being the terrible idea not to make provisions to build a false wall/AT setup. My stage is deep enough, but the soffit wasn't made to accomdate the false wall. I was too concerned about the front row being too close to the screen.

One issue I didn't mention is with the large sub box it really limits me from increasing my screen size down the road. Right now i'm leaning towards big sound over a larger screen.

that's a nice room that you are putting together.

a quick couple points. here is the max spl in 2pi space of the marty sub vs. sealed for the si 18ht driver (Dayton will be down a db +/-, but more or less identical).



if you aren't shooting for single digits, the ported can offer a lot more spl across a portion of the bass region. each person has to decide if that is a tradeoff worth making. for most folks with one or two subs, it is almost certainly better to go ported if you have the space. if you have 8 or more subs in a home sized room, there may be sufficient spl even without porting to do what you want to do (well, 'not in all cases).

the martysub is just one expression of a largish lowish tuned sub that was designed to be relatively easy to build and extract the most performance from the combination of the low cost drivers (si 18ht/rss460ho) and the inuke amps. there isn't any particularly special about the dimensions, so similar performance can be had by changing dimensions to fit the space. if something a little shorter would be better, that's no problem.

Listen. It's All Good.

btw, in your room, pressure vessel gain will kick in starting at about 24hz +/-, so below that you will get a lot of "free bass".

LTD02, you're such an asset to this forum, seriously... one of the best! Do you think the standard Marty box stood up will be stable or do you think it would be better to point the port up and mount the woofer front and lower? Seems with a box that large it should be stable enough to stand with the woofer up. I guess I could always strap to the wall for safety. The graph looks pretty telling and powerful smile.gif

Excellent! I have been considering Jbrown15's recommendation to go with the Mach 5 UXL-18. I searched around and only found a few reviews. Some complaining about voice coil rubbing/noise. Does anyone here have any opinions of the UXL-18? I like the specs but I'm a tad hesitant at this point given the cost.

The UXL-18 is an excellent driver. I personally have, and like, the Dayton HO18's, which are also excellent drivers. The UXL-18 is better than the Dayton HO18 and SI18, but at a substantially greater cost. If I had to pick between two HO18's versus one UXL-18, I would choose the HO18's because the benefits of more than one subs far out weigh the increase of performance with regards to the UXL-18.

That’s a very good point Marty and although I agree with you, in the end I tend to go with the better driver up to a certain point because of adjustability with other applications and oh I suppose just because. Both are good options 1 or 2.. I know you’re not saying they’re not though.
