Hi there.
I’m using this unit here: https://www.amazon.com/dp/B09YNBHR73
The issue I am having is subwoofers and not having a lot of money to fix my situation.
I currently have that 3 x 8" ported Skar box, but it has such low impedance that the speaker safety trips constantly on it. Godzilla help me if someone says a word with a p in it.
Is there a way for me to rewire that setup to gain more impedance and stop it from cutting off or should I move on and get a single 12" for the small box I have? (I have a behind the seat single 12" enclosure.)
I’d obviously love to have bass as deep as possible, but any options would be nice.
Thanks
Oh, sorry.
Box dimensions: 13" bottom depth
8 1/2" top depth
14 1/2" width
13" height
Measured from the outside.
Material is 5/8" thick MDF
Thanks, I will look into it tomorrow. How much would you spend on the 12”?
Around $100ish would be ideal. Has Cerwin-Vega been enshittified yet?
I get .885 cubic feet, which limits the number of 12" subs that will work with it. Of the home hifi subwoofers that I would use in one of my projects, only https://www.parts-express.com/Dayton-Audio-RSS315HO-4-12-Reference-Series-HO-Subwoofer-4-Ohm-295-466 fits the bill, but it is more than you wanted to spend. This car sub would also work, but it is about the same price: https://www.parts-express.com/Kicker-CompRT-12-12-DVC-Subwoofer-4-Ohm-267-614. I know you can find car subs elsewhere for $100 or less, but they often don’t give you enough specs to determine what size box that is appropriate, like this https://www.amazon.com/Skar-Audio-IX-12-D2-Subwoofer/dp/B00NHVC7TG/ref=sr_1_3 Car subs are also optimized for gobs of power, meaning they are not very loud, so the more modest power provided by the Fosi might not be adequate.
Any reason that this guy here wouldn’t work?
I can’t really say without detailed specifications or a recommended enclosure size and type (ported/sealed). If you can find the TS parameters for this woofer, I can model it for you.
The info on page 5 what you need?
Page 6 has recommended enclosures for it as well.
You would want the single coil version so that you can get 4 ohms. H7124S (https://www.amazon.com/CERWIN-VEGA-HED-200W-High-Energy-Subwoofer/dp/B071ZC4FQL/ref=sr_1_1)
I modeled the single coil version and this is the response you can expect:
What you can get out of this graph is that you won’t get much bass below 40Hz and a peak around 70Hz.
Sorry, confused as to why I’d want SVC over DVC when they are the same Ohm?
Because with 2x 4ohm voice coils you would either get 2ohm in parallel or 8ohm in series. Neither are ideal. With a single voice coil you get a single 4ohm input. DVC is really ideal if you have two channels that you want to connect to a single sub. Each channel would get 4ohm.
