Apex Jr Super 8 Sub Woofer Page
The Apex Super 8 Subwoofer has a great following and offers the best bang-for-the-buck performance of any 8" sub currently available. It outputs very tight, deep bass at volume levels much higher than expected for a small driver..
|FS=47.75Hz||Qms=7.334||Qes=.552||Re=2.653 ohms||Spl=85.22 @ 1w/1m|
|Vas=0.376 cu. ft||Le=0.157mH|
Voice coil length is a respecable 19.8mm, the top plate is 10mm thick So Xmax is 4.9mm
Here is an new design by Chuck Sheershmidt using the Super 8. .http://www.angelfire.com/jazz/noidster/fourplaysub.htm
Here are projects and pictures submitted to us by our customers and friends.
I had a friend of mine ask me to build him something for his HT. He had a few parameters that he asked me to follow:
|1. Small Size.|
|2. Apparent output but not overwhelming|
|3. All Black Enclosures.|
|4. High WAF.|
Box is covered with Black Formica. The bottoms of each woofer are covered with Vinyl. Each foot has a floor
spike. (Dayton -http://www.partsexpress.com/pe/pshowdetl.cfm?&DID=7&Partnumber=240-716 ) Over all I was
very impressed with how these turned out. I was afraid
they would not be loud enough and for my tastes with HT I had to run them rather hard and thought they would have been better with a bigger amp (http://www.partsexpress.com/pe/pshowdetl.cfm?&PartNumber=300-793&DID=7as an example.) When I hooked them up to my stereo I was amazed. I have never heard 2 - 8 inch woofers put out the kind of bass these did. I REALLY enjoyed these for music. Allot. After I had the test boxes built I talked to my friend a bit more and got a little nervous when he said he was going to use these with his B&W speakers. So now all I can think is "Great, I know have to compete with B&W's" So I continue on and finish them for him. On the day of delivery we get everything hooked up and all he can dois smile. (Which of course makes me happy.) After tweaking everything out He asks his 8 year old daughter what she thinks about it and she says "It's loud Daddy." And then he asks "Yes, but do you like it?"
And she replies "Yeah, Its just like the Movies." He turns to me and goes "Sold" So all in all, customer was happy, I was happy. Unfortunately, I now want to build a set for my self. But that's a whole other project for another time.
Pics are below. Feedback encouraged and welcome.

BTW - Pictures aren't that great a quality. And I forgot to do a final cleaning on them before I snapped them so you will see some streaks and finger prints. Hope it does not take too much away.
