Your bucket subs look great Poultrygeist! Do you brace the insides in some way? I also like how you finished the sub amp.

Well done.

Regarding the FH3, I've never had the pleasure of hearing them but if they're similar to the relatively small back horns I've built then yes, they would benefit from a subwoofer. The advantage of back horns IMO are they way they increase 'jump factor' compared to sealed or ported boxes. I'd imagine a larger amount of air being moved (due to the horn's mouth) contributes heavily. I love them for that! But they are not necessarily bass champs.

jjcarr, I enjoy the spooky imaging thing OBs do too!

Really depends on what the drivers are. I've got the prototype P_10 FH3's at home, with Fostex FX120's in them. They have very good low bass output, and don't require a sub.

Fostex FX120...

I stand corrected.

Bucket subs using $66 Peerless woofers, 5 gallon buckets from Home Depot and a Yung SD300 plate amp.

Clever!

Thanks. Here's the bucket sub recipe. I understand their inventor uses them with his HS horns.

These OB H-frames also partner well with the FH's. They won't plumb the depths but they offer very accurate and natural bass that won't disturb the neighbors.

Poultrygeist,

What drivers in the OB H-Frames?

That's an interesting setup to play with, I haven't tried that yet, but easily could.

Amps?
 
Dayton AP 150s in mono on subs? - what about the FH3s?
