Joe f posted a topic in Sundown Audio - GREAT Amps/Subs! GREAT Customer Service!I really need help with a box design for a zv3 15" d1 that I just picked. I have it in a Dodge ram 1500 reg cab. I pulled out the center console and built a box between the seats. The first box I tried was 3ft after disp @34hz using 2-4" ports and running off a sundown sae1200. The sub was facing up and ports coming out the front towards the dash. It sounded OK but would not play Lowe's very well for a 15" sub. So I built another box that is 3.5ft after disp @ 31.5hz using a single 6inch port, same with sub facing up and port forward and it still does not pick up lows like I think it should. Is it the port size? Is it the single cab of my truck? Is it the way the sub and port are arranged???? Any help would be great, thanks!!
Putting together a new temporary enclosure for my Powerbass 3XL 15. I am using a single 15 enclosure that was custom built by a well known local builder, 4.3 cu. ft. gross volume, 1" MDF, currently tuned to 46Hz with a 4" aero port. I believe the guy had a little Kicker 15 or something in it, nothing big at all so one 4" aero was fine. I however, want to modify the box to better suit my 3XL for the time being, until such a time I can afford a second sub and build a nice box. What would be a good port size/quantity for my sub? I would like my optimal output to be between 30-33Hz, so I figure I will tune at 31-32Hz. I used a port size calculator, entered the Xmax and desired tuning and it recommends a minimum diameter of 7.51" and minimum port area of 44.26". My old box was the same size, same tuning, different dimensions and with two 4" ports it suffered on lows but had great output at 38+Hz. I tried an 8" port and it sounded like wind blowing and was a big loss to the ear-o-meter. So if anyone has any ideas as to how many of what size ports would be optimal in this situation, I would appreciate it! Here are the specs for my sub... http://www.powerbassusa.com/sites/powerbassusa.com/files/3XL_Woofer_Manual%20v2.pdf Thanks!
Hello everyone, This is my first post here, or on any forum on the interwebz. Thank you all in advance for any help you can provide. So my old focus hatchback decided to kick the bucket and I purchased a 2012 chrysler 200. Not my first choice of bass car but its nice and they were the only dealership in the Ann Arbor MI are that could get me a reasonable loan. I have 1 Sundown Z v.3 18 that i would love to try to cram in the trunk, i built the box for it that was in my focus but it will not fit in the chrysler so im looking for advice on how to make the proper choices for port size and what not. I do not plan to compete, i like it loud but clear also. Im not a strick audiophile but i can tell whats good and not. I love the lows, feeling the music is the best part but i listen to all sorts of music not just rap so id like to be able to have a bit of range. The trunk has a max height of 14.5 inches (that includes space for the woofer to move), 38" wide at the smallest point and id like to keep it to a max length of 30ish". I obviously dont care about having any trunk space left, thats why we have back seats right? For the time being ill be using my orion hcca 10 in the spec ported box that i paid wayyy to much to have the local shop build a few years ago. Power is a Hifonics Brutus brx 1600, kinetik hc 2000, knukoncepts ofc 1 awg, stock alt, new front batt soon and big 3 soon, there is only the stock crap in the car right now. And i know the amp isnt amazing but it gets the job done. So after the longwindedness you just endured what would yall say is a good port option? 6 to 7 cube box, i know the rule of thumb is 12 to 16 in sqd per foot cubd, id like to be around 32 33 hz. I was think an internal height of about 11", sub mounted up to a single baffle with a second overtop to make it flush and add strength and some 2x4 braces around the cutout. Single baffle everywhere else. My last box i messed up on calculations (first time) and ended up tuned way high but it sounded pretty good, got loud and still played down into the 20s. It is 1.5 inch mdf all around, resind the inside, 45d the corners, bedlined the outside, it weighs more than my gf with a purse full of rocks. Id like to go birch and stain it this time Thank you all again, im open to any and all suggestions. I can post pics too if anyone wants. As an fyi i have no comp to use any box building software since my macbook pro was stolen a year and a half ago so im all website calcs and paper.
ridinclean97 posted a topic in General Audio - Can't find a category for your question? Ask here.Ive got 2 15s in a 7 cube box tuned to 32 hz. Ive got this port http://www.amazon.com/gp/product/B000HJ9SAC/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1 Its just 1 6 inch port very generic. How much power should I run to avoid port noise? I was thinking 600 watts but idk.
