Bucket Sub
« on: April 04, 2018, 01:55:16 PM »
I am wondering if someone might be able to give me some advice. I'd like to build a bucket sub to add to my system...I'm curious as to how it would sound with my FrugelHorns. I have the directions to build the sub, however I've no idea how to wire it into my system.

My thoughts are to utilize both plate amps, if that's practical, and use them to power the subwoofer. They are Dayton SA100's which I believe generate 75w each.

I have done some searching on the web, but have not been able to find anything indicating how one might do this. Any assistance would be appreciated.

If at first, the idea is not absurd, then there is no hope for it.

Do you want to build one bucket sub or two? 

As far as I remember, the woofer called out for the Bucket Sub is a single voice coil woofer, so using both plate amplifiers isn't going to work.  I'm also of the opinion that 75W for a small sub is a ton of power.

As far as connections go, just run a second set of speaker cables from your Stereomour to the speaker level inputs on the plate amp.  The input impedance on those terminals is sky high, so it won't load the amp down. 

(You want to build two bucket subs, right?)

Jeff, I have been thinking of trying the same thing (2 bucket subs, 75-100 W plate amps) for my FH3s.
Currently I use Dayton's 100 W plate amp to run a single 8" sub in my office with a SEX 2.1 wired as Paul suggests. It is decent but inefficient 4 Ohm sub, designed for car stereo, in a small sealed enclosure. The 100 W plate is running almost wide open to blend with the little single driver micro-fonkens, and I'm no bass-head. Just my experience, a more efficient driver in a larger enclosure would no doubt help.
I've poured over the various write-ups, even the nay-sayers, about the bucket sub, and it seems like a no brainer to give it a try for the modest investment. (2 subs + 2 amps)

If you have the 2 amps, do build 2 subs. The bucket subs are   Serious overachievers, I dismissed the idea until I was down at Ed's and heard them. I am useing a  variation of them With the Horns and they work very well indeed

Thank you all for your input. I will build two subs as suggested. To add the second set of speaker wires to the Stereomour will four of these splitters be the best way to accomplish this?

No, speaker level connections require speaker wire.  Just grab some plain old bare speaker wire for the job.

I'm finally have some time to assemble my bucket sub. I'm wiring the woofer to the binding posts, unfortunately all I have on hand is some 22 gauge hook up wire. Will this suffice, or should a heavier gauge wire be used?

You can always double or quadruple the wire. Each time you double the wire the equivalent gauge increases by three, so doubled would = 19 ga., quad = 16 ga.

I have the bucket sub running and I'm instantly impressed! Well worth the small investment in time and money! This has transformed the sound...I can no longer listen to the FrugelHorns without the sub. It will be interesting to see what the addition of the second sub will do for the sound.
