Newbie First Build Questions
10/24/06 at 15:42:20
 
I've been reading the posts in this forum for a couple of weeks.  There are a couple of questions I still have regarding my particular application.

I'm planning to build two 15" or 18" HW cabs for music playback in my recording studio.  They will be in a 20'X30' room for the bands to hear what they've recorded.  The "top" speakers will be JBL 4311B's, ( 12"WMT), W/2 stereo amps and an active x-over.   I'm primarily concerned with a good, tight "true-to-life" sound and not really concerned with anything below 20Hz.

My questions are:  
1)  Best way to load?  Seems like 1-up/1-down is recommended for music by several people...

2)  Best Speakers for this cabinet considering my application?

3)  I'd like to place the JBL's on top of the HW's.  Has anybody moved the port?  I know. . . "don't change the design"!  But, Ive heard that a port can be moved if it is: "at least the width if the port" away from an edge, and "at least the width of the port" away from the closest speaker.  There was also a post about a slot port but I can't find it.  

Thanks in advance for your patience in revisiting these questions.  I know that they are probably listed elsewhere, but after a couple of weeks of looking, everything isstartingtoruntogetherandi'mgettingconfusedandi'nfeelinflikesuchadumbs#!t.

Blake, I've got some experience with the HWK, however my goal was not musicality. I would think the room would have a huge effect on driver placement and quantity needed. That's a huge room, so you'll be needing at least 2+ per enclosure I'm sure. What kind of music? How loud?

My first build was two drivers with magnets in center chamber, wired p/p, with a 900 watt amp bridged. Seemed pretty musical to me, but It didn't take me long to deviate from that to Home theater.

Hopefully one of the "HWK pros" can help you better.
--Check out the HWK white sheet for Steves recommended loading, also.

Hey Blake,

Welcome to the forum.

Someone I know has turned his HW upside down with little feet on the bottom(top).  This way you could stick to the plans and be able to put whatever on top.

Just a thought.

Kiss  Thanks Dennis    ;D

The feet were glued, screwed, and nailed.
Very permanent.
So when I flipped upside down, it looks funny. Embarrassed

There was a day here awhile back that I could tell you the resonating frequency of every light fixture in my room.... and upstairs.

Yea, it rocks.  :D
Blake will like it if we can "get him hooked up". Grin

Dennis, how is yours set-up?

Thanks for the feedback!

The "upside down" idea makes a lot of sense. . . like sofa feet-size?

The JBL's are old-school 3-ways that can get pretty loud.  If anyone remembers the old L-100's, they are the same thing with upgraded components designed for studio use.  I just had them rebuilt (cost a small fortune).  They can make your ears distort before the speaker does with only about 150 watts.  Now I need some, "knock-your-di Shockedk-in-the-dirt" subs to finish the job.  This system will allow the clients (who wish) to hear their stuff back real loud.

I'm not an audiophile. . this system is for the "wow" factor, as we say in this business.  Mostly for metal and rap clients.

Hey Blake,

You may just be a candidate for  Imperials instead of the Housewrecker.

A thought.

Yea, kinda.... What I did was took one of the waste pieces from the driver cutout (15" diameter MDF circle), cut it like pizza into 4 equal 'slices'. I then ran the 'slices' across a router table to "get the edge off" using a roundover bit so the heavy S.O.B. could be scooted across the carpet easier. Then attached them to the bottom of the HWK (which has since become the top Roll Eyes)

I think we might just be able to thow the 'musicallity' thing out the window and try to break some of your windows......

I'd recommend building one or two, listening for awhile, if it's not enough, do the mods. I've got db/HZ numbers, but they are for a different driver.

hmmm. More visual wow factor than a HWK...
Might be a good idea overall

..visual and audio "wow". . . however, I love the combination of beer, power tools and the smell of MDF in the morning; and I don't think my liver could handle a set of Imperials right now!

What about your lower back moving around an Imperial or two?
--Not that the HWK is an easy one to move around. (trust me, I threw my back out when I flipped it upside down Roll Eyes)

Anybody know what a HWK15 wieghs? with or without drivers?

id think youd need longer feet than a few inches if you flip the hwk, 6" minimum for an 18"

why would you need 6" feet for a hwk-18 ?
x2 on the imperial idea. that would really kill.
imo, you need a pretty accurate design is you will play mostly rap and metal.
i'd estimate an imperial at about 250 - 300 lbs if made out of mdf. so the hw won't be such a bish to move around.
