Following the design I got from Elemental Designs, I built a ported box for 2 Ehqs 12's.
They are S2, wired in series with a 4 ohm load. They are powered by a bash 300 [300w @ 4ohm]

The Design:






Cut Sheet:


You know.. it looks smaller on paper than when you actually start building it....

 

Look it works like a table too!

Finished:

 

The amp.. I built a seperate box for it so I could keep it on my desk. I am going to control the volume from there...





A side is open for ventilation purposes



The amp and subs are linked together with speaker cable going between the two speaker cups.

Now.. for impressions...

I have yet to break these beasts in...


I live in a private house.. my room is in the 2nd floor.

The whole floor started to shake.. the box started to move by itself

Sitting on a rolling chair, I was actually rolling.. it took me a few seconds to realize why lol

Blueberry Yum Yum [byy] was my favorite song to throw at them... they go absolutely crazy. There is so much air coming out of that huge port that you could hurt an animal lol.

This thing is coming with me to college [its my dorm subwoofer lol]
so tonight me and my friend are taking it there.
We are taking a train [one train and then a transfer to another]
so it should be fun carrying this huge *** box through the trains and then walking like 10-15 min to my dorm in philly.

The box itself was done in about 4 hrs total [2 hrs * 2 days]


I am quite impressed.. with amp, subs, wood, screws and caulk.. cost was about $220

 

Here is a shot of my room [home not college]
so you can tell how freaking big it is



yeah.. thats 6 speakers [2mtm, 1ht_sub, 2 studio monitors, 1 eqhs sub box]

The eqhs 12s are now fully broken in.. .and all i can say is WOW!

I can make my whole dorm room shake.. to the point where glass bottles are clanking and lights are shaking.

I have had noise complaints from upstairs AND downstairs
[which is through a good 5 feet of cement lol]

 

Very nice. That garage needs some cleaning though.

 

The 15's look just like my Dayton. Do you have any pics of the motors?

 

Where did you get that amp?

 

oh jeez...slight overkill for that room no? haha

 

That's effing huge. Where in Philly do you go to school? I'm there all the time.

 

DUDE, where were you when i needed a box built? you do some good frekin work man...

 

thanks for the kind words guys...

nilesh.. I go to drexel.. right next to amtrack's 30th st station.
Filtor, those are 12s.. heres a pic of the motor:

not that great of a pic..

ascendant.. my dorm room is smaller than my house room .. about 1/2 as big... so yeah.. umm.. slight overkill lol

the amp i got also from elemental designs.. but i'm pretty sure they buy them from www.partsexpress.com
They have a nice sale on it right now.. only about a 100 bucks.. and free shipping!

 

i would hate to live next you.

 

are you just going to leave it bare mdf? cover it in those marble laminate.

 

I know where Drexel is, I party over there and chill at USP a lot. Which building you live in?

 

That is sick! Must be nice, can't beat $25 subs.

 

hmm sounds like kelly or calhoun

any details on the mid/hi's?

 

nismos.. yeah 25 is nuts.. it was 40 when i got them.. and it was still a steal.

nilesh.. thats crazy.. i party at usp a lot too lol

im in North.. 3200 race st.

the box is gonna stay bare mdf... its under my bed lol.. who cares how it looks?

mid/his are handled by a pair of m-audio proseries 3
[not bad at all for the price]

 

Nice, the motor is def different. Sick project though.

 

thats farking rediculous... post up all the pieces (names) and maybe links to the stuff u bought, I think i wanna do something like this too.

 

Where did you pick up the Bash 300s?

 

you can get the bash from partsexpress.com

drivers.. only 25 bucks a piece .. www.edesignaudio.com

 

Thanks for the links, sorry I missed that in your earlier post. The amp in my BIC Venturi 1215 sub crapped out, just looking for a good replacement.

 

Wow, I thought I was the only person with BIC venturi's. I just have a pair of bookshelf 6.5's though. They do sound very natural.

 

I love this sub, but have been without it for over a year. Not a major priority.

Sorry to hijack.

 

I got an update email from PartsXpress today letting me know that they just now got the Bash 300 back in stock (out since before Xmas). While it was out of stock the sale price was $105, now that it's back in stock, the price is back up to $150. Sent them an email and they're going to honor the sale price.

 

I don't know if its mentioned, what is the box tuned to? low 40's?

 

it's tuned to 30 hz

 

I'm glad you kept your shirt on this time. Box looks good though.

 

Filtor1 isn't...
