Fi Q10, Hornresp, D.A.T.S, vs. Me :)

How to start this off?????

 

Well, I got this way cool Fi Car Audio 10" Q. Here are some pics of how it arrived to me.

 

Waiting at the doorstep.

 

Opening up the box.

 

Out of the box and on to the driveway for some pics.

 

Side profile shot.

 

Get a load of that motor. O_o

 

A word from the people who made this possible.

 

The plan will be for a simple ported box with an aero-port. I'll input all the manufacturers parameters and box specs into Hornresp and see what it chugs out. To follow up, I'll use a Dayton Audio Test System (D.A.T.S.) formerly know as the Woofer Tester, to verify the impedance curve and box tuning.

 

If all goes well, I'll have a nice bumping system. Worst case, I get flamed to death on the interwebs. Stay tuned.

Tuned in for the testing!

that sub looks AWESOME !

Alright, well, thanks to all who have commented so far. Not much happening just yet. I had to mow the lawn today. :/ Good thing, is that a cold front rolled in, so it was nice and cool outside.

 

Now the good stuff. I broke out with the old tape measure and took some measurements of available space. Scratched my head and stared aimlessly at the Hornresp Input Parameters screen. Then I came up with this:

 

Box volume 1.5cuft (42.47L). Port specs: 4" aero port (81.03cm^2), length 17" (43.18cm). Tuning: 33.62Hz

 

Hornresp Input Parameters screen.

 

SPL Response, 1w@1m, I think. Eeek! look at that peak. O_o

 

Impedance Curve. :/ Looks right to me.

 

Group Delay. I have no idea.

 

Here is a sketch I made of what I'm gonna build.

 

Excuse the mess, I'm left handed. That's it from me. Now your its your turn. Share your thoughts, suggestions, and predictions.

I tried to use hornresp once. It was a mess and I gave up lol.

I have the same dats. Its pretty handy and makes tuning and testing a breeze. Gonna use it to figure out my next wall.

I had the q18 and I think you will be surprised what a nice all around driver it is.

When are you going to start the actual construction?

Your not kidding about Hornresp being a mess. Members of some of the many home theater forums have written up pretty good how to instructions for the various alignments/box types. (Hope I worded that right. ) Hopefully I followed them to the "T".

 

The DATS is pretty cool. How "spot on" it is, is up in the air though as I have no real reference other than what manufactures post and what I model up. I'm just trying to learn and have a little fun on the way.

 

The build is well on it's way. I just need to catch up and post up the pics.

The specs will change depending on the environment it's tested in. However it won't be enough to make a difference for the enclosure.

Good to know, thanks.

Here are various shots of my box build.

 

I had been hearing many things about "Arauco" plywood so I decided to give it a shot. A bit shout out to the fellas at the Home Depot around the corner from my house. Those guys have always been cool about trimming the wood down to manageable sizes with their awesome panel saw.

 

The goods:

 

Another change up for me is using a nail gun instead of wood screws. This made it so much easier and quicker when being an army of one.

 

The box coming together:

 

Under this stack is the baffle being glued together. On a side note all that wood is for a project I said was going to be a quick one. Joke is on me, that wood has been sitting in the garage for a year. :\

 

Here is a shot of the baffle ready to go on the box.

 

I though I'd give the box edges a little round over.

 

Assembled box pics.

 

A little shot of the terminal cups I made up for the box.

 

Sub, meet box. Box, meet sub.

 

Woot, woot! Box finished.

 

This is officially my fastest box build. It took me a week of afternoons to pull this off. Hooray for me.

wow hugo  perfect work as always.. you are a master of craftsmanship !

Thanks Jon. Maybe this time the little Olds will break a 140.

[eggyhustles 33]

That looks good!

[Shogen 325]

box looks great... how did you like that plywood man???

box looks great... how did you like that plywood man???

 

I like it. It's got less voids in it than the oak/wanna be birch ply they sell at homedepot. It's lighter than MDF. Most importantly, when I cut it I get the feeling that I'm breathing in real wood not all sorts of carcinogens like when cutting mdf. Makes me feel like a lumberjack.

lol... I want to feel manly too....

Hahah good shyt..lol

[edouble101 314]

Man I wish I could carpet a box that good!

[onebadmonte 235]

Yay! Day off updates!

 

So here are some pics of the last iteration of the system in my little Olds. A.K.A. "The Creampuff"

 

What a mess.

 

And what was hiding behind the rear seat.

 

With everything out I positioned the box in place and decided on using an angle iron to secure the box to the car. I started off by installing some 1/4-20 rivenuts in the trunk floor.

 

Here is the angle iron bolted down.

 

Looking through the old baffle

 

I transferred the hole locations from the angle iron on to the box. I followed up by installing threaded wood insert into the box allowing me to bolt the box onto the angle iron with three 1/4-20 x 1" bolts. Here is some shots of the box bolted to the angle iron.

 

Lastly here is a pic of the final install.

 

The final system layout consist of:

 

Headunit: JVC KD-HDW10

Processor: JBL MS-8

Front Stage: PowerBass S-352 3-1/2" Co-Ax in stock location powered by MS-8 hi-passed at 200Hz 24dB/oct

                     Peerless OEM 8" powered by US Acoustics USB-4080 (bridged) band-passed 200Hz 24dB/oct & 80Hz 12dB/oct

Sub Stage: Fi Q 10 powered by Bazooka MGA11000H lo-passed at 80Hz 12dB/oct  sub-sonic at 30Hz 24dB/oct

 

Test and impressions on the way.

Came out great!

You didn't want to play with positioning before bolting it down?

[dbsupra 69]

Also kinda hard to tell in the pic, but from the orientation it looks like the port is fairly close to the side.

That being the case don't be surprised if the dats shows lower than calculated tuning.

Don't forget to use the calibration resistor each time you fire it up!

[jonbearsmt 919]

 that would be the only way i would do a side port.. i like mines to load off of something,

 

 came out great hugo im glad to see you left the IB baffle

 

 

 you need to get that bad ass moteCarlo finished that Q would be at home in that clean sex sumbitch

Thanks. As for box position, I figure I'd just drop the silly thing in and take my chance with hitting a home run right out of the chute. Most likely that isn't gonna happen.

The pis make the port look close both there is a good four inches of clearance. The DATS will tell the truth though.

The ib baffle stayed in jus because Im lazy. : D

Awe, don't tell me about that Monte Carlo. It's a love hate relationship with that damn car. I tell you it gonna be the end of me if I ever finish it.
