Is the custom box I had made too small?

I have a 10" Massive Audio Kilo 104.

The product manual that came with the subwoofer states that a sealed enclosure should be .75 cu ft taking into account displacement which is .0963, that would be a box with a total volume of .85.

The manual on Massive's website gives a range of .88 (small)-1.25(large) for sealed enclosures including displacement. The guy I had build me a box at a local shop said the box should be .8 cu ft ?? He said he was calculating off of different specs in the manual. Now granted I have no clue about this stuff, but a net volume of .70 sounded outside of recommended specs....so I asked him to just make it 1 cu ft...he said OK. I went to pick it up today and I get home and measure it and it is .8 before subtracting displacement. I paid $150 for this thing, I want it to be right.

He mentioned calculating off of Vas and stuff like that. I haven't called him since he was gone when I went and picked it up, but I just want to make sure I have my ducks in a row.

 
Wow, $150 for a sealed enclosure, sounds like a tough sell to me.

Anyways, being that small of an amount under spec won't really have that much of an effect. If you're that concerned with it, you can always use a little bit of polyfill to make up for any needed difference in volume. There's a ratio somewhere out there online.

Edit: In case you don't know, polyfill changes the characteristics of the box to make the sub respond as if it's in a larger enclosure.

 
I agree with Buck.. if you asked for a 1cf enclosure, that's what you should have received. Unless you were far off on what you requested, in that case he should have explained why before building it! Also $150 for a sealed enclosure less than 1cf is outrageous! Personally, I would throw a bit of polyfil in it and call it a day. (Just because I'm not a confrontational type) Most likely you couldn't tell the difference between the current enclosure with a bit of polyfil and a 1 cf enclosure but bottom line you didn't get what you paid for!

 
The gif, yo. Dr. Dre's face is priceless. Like, what you gonna do about it?

LOL Thanks //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif - I hear you build some killer enclosures, OP should've hit up the forum & enlisted your skillz before he got bent over locally //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif

For the tools that we have and the size of our tiny shop, we sure have built some good sounding enclosures. We shit on all the local businesses in that aspect. But most people are just ignorant about how big of a difference a box makes. They hear our celica with 2 AT strato 10's in it playing 27 at full tilt and are like, oh, I get it now. It's funny, there's a local guy who had 6 re xxx 18's on who knows what kind of power. People who have heard both said that my 2 4 year old Fi Bl 18's on 2400w in a box that I built when I was 18 in my garage with only a drill, screws, and glue (no clamps, no table, no nothing, 14.6 cubes net) was as loud or louder, and wayyyy lower. I'm like, lol, I'm 18 and did all this in my garage with a poor mans tools. And these guys were a "professional" shop. The box was tuned to 27-28 hz for goodness sake! It wasn't even meant to be loud, just to play tardy lows and I was just shitting on everyone local with thousands and thousands in their system. I just know what I'm doing and they don't frankly.

NICE //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif lolz that's sick! ...The same can be said for most shops I have either worked at or visited in my area - They don't know jack about building GOOD enclosures, Nice 2 meet you & glad to see you back in the forums postin' up, I saw that you have had a rough time l8ly, hope all is well, keep doin' your thing Buck //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

 
I was quoted $120, but when I got there to pay there were material charges (wood) for the box (nice if they would have told me that up front) plus tax....so yeah I paid more than I should have, but nevertheless I can't figure out how he came up with .8 cu ft and a net box volume of roughly .70....nowhere on the Massive's literature does it recommend anything that small. I'm going to call today and talk to him and see what happened. I believe this is a west coast chain of stores, probably should of ordered through one of the vendors on the site, but I was under some time constraints with getting everything installed (not at the chain I speak of).
