I've been helping a buddy install a system in his 2016 Jeep Wrangler JK. I finally have enough pics to start a build log, so I'll be loading all of them up over the next couple weeks.
The requirements were simple: he wanted (4) 8's or nothing at all. Silly? Maybe; but we met the requirements and hope to be banging before the end of the year
The stock sub (an 8x10) has 4 voice coils
Ran some numbers in TermLab at first, but then switched the design over to WinISD. Came up with this size enclosure:
That router feels good man
Went with PSI-8's with High Performance suspension for 600Wrms per sub
We were jammin some of that good techno
The original plan was to have a few tube ports, but I had a hunch that they were too small. Thats about the time that Triticum came out with his port velocity calculator, and I realized the port velocities with these small ports would give me the tuning we were wanting, but also gave us almost 100 m/s port velocity (yikes!)
Then the design changed to have a properly sized port attached to the back panel, bringing the velocities down to around 25-30 m/s
I didnt really trust my kerf skills yet
More pics coming tomorrow. Thanks for looking!
Buddy's new (new to us) amp. Got it used through Cody at Droppin Hz for a good price.
On to the pics:
Very interesting heat sink
Amp was built one year ago and warranty is non-transferrable, so off comes the warranty stickers
Used alcohol to remove the warranty stickers
Cant wait to get this badboy playing down at half ohm
I have 3 orion HCCA 152 woofers that im running on some off brand 3500 watt amps. I wanna go with one solid amp to run all 3 at a 1.33 ohm. this is a daily driver 2003 trailblazer but I want it to hump. the woofer are rated at 2500rms/5000peak, I currently have 5 d3100's in the back, 1 redtop in the front that I want to change out but need to find a battery that will fit due to the dual alt bracket that holds a 240 mechman and a 370 mechman. out of these 3 amps, which one would you recommend I run on those 3 woofers with my current setup. thanks for any assistance you can give me.
I’ve designed an isobaric 6th order series tuned bandpass enclosure for my wife’s car. I want to build a series 6th for experience and for science.
I have a firm grasp of the ins and outs of WinISD, but I am new to BB6. So I started with measured values from my ported design with (4) 15’s, which I have dialed into WinISD and is pretty accurate. Then I modeled the same box in BB6 to see the variation between the two programs and measured values. That gives me a baseline ‘feel’ for BB6.
Can someone check my design? I plan to test and modify the design to optimize the performance, and then I’d like to funnel that real data back into BB6 so I can really get a better feel for the 6th order designs in BB6.
Here’s what I’ve come up with so far… This got me the most area under the curve but also a decent low end response:
[INSERT PIC HERE. I COULDNT PLACE IT HERE WITH DIRECT UPLOAD]
Low port (for the design shown above) is 6”H x 3”W x 33.3”L, with 2 flared ends
High port (for the design shown above) is 8”H x 3”W x 8.4”L, with 2 flared ends
Goal was to keep port velocities under 30 m/s, cone excursion within limits, and boost the low end response without getting a severe dip between the two port tunings. I really couldn’t bring the high tuned amplitude response down, maybe I need to widen the bandwidth? Figured widening the bandwidth would cause an undesirable dip in the middle.
Here’s the real measured TS parameters (via IM-SG) for the well-broken-in pair of Pioneer TS-W3003D4’s:
Dual voice coil, wired in PARALLEL (for measurements below) and both subs wired parallel to the amp.
Re (parallel, each sub) = 1.6ohm
Fs = 31.4 Hz
Vas = 2.822 cu ft
Qms = 3.706
Qes = 0.494
Qts = 0.436
Mms = 126.9 g
Cms = 0.203 mm/N
Dia = 10.2”
Sd = 81.7 sq in
Xmax = 14mm one way
I’d like to set the tuning for the low side at 31ish Hz and tuning on the high side at 63ish Hz. The subsonic filter setting will be determined via testing after the box is built and tuned to its final state.
I have about 5 cubic feet total to play with for this isobaric series 6th setup. I can toy with the final XYZ dimensions, I’m mainly looking for a solid set of values for volumes and port areas & lengths (if the ones I calculated in BB6 are not suffice). Rectangular ports are preferred but I can do aeroports or kerfed circular port if that’s a better route. I am competent with woodwork.
I’ll be starting a build log for this box design and its installation. Planning to include a lot of measured data (IM-SG and AMM-1). Really stoked for this build.
Thank you in advance!
