Hi,
I am considering building a small sealed subwoofer to compliment some small full-range speakers I am building (which are following Zaph's design quite closely and incorporating HiVi B3N drivers) and was wondering if the aforementioned Dayton unit would be suitable?
I would like it to be fairly small and "punchy". Can anyone perhaps comment on this driver or suggest anything more suitable preferably at a similar price range? Would the 10 inch version be better for music in a medium sized room?

I don't have any particular size in mind, whatever the driver requires. I just wondered if anyone has had any experience with it. I will model it in WinISD when I get a chance.
Hi,
Quick modelling indicates a sealed well stuffed box 0.3 to 0.4 cuft.
A plate amplifier with built in low bass boost is a good idea, as
the bass extension is not inspiring.
0.8cuft tuned to 30Hz is much better.
FWIW the 10" Bravox at PE looks decent enough in 0.8 to 1.0 cuft
sealed, and is probably your best bet for sealed in that price area.
Better extension, but a bass boost option would still be good.
(On paper, if you trust the specs.)

My personal conclusion is that the JBL GTO 804 is the best driver overall for your application.
The Dayton Audio DCS205-4 8" and the JBL GTO 804 both had pretty similar performance.
The Dayton Audio DCS205-4 8" had slightly better group delay, although this is probably an inaudible difference.
The Dayton Audio DCS205-4 8" has lower moving mass, theoretically giving it faster response/better SQ (debatable).
The Dayton Audio DCS205-4 8" needed 80 Watts less to get to max SPL (although lower on average).
The JBL GTO 804 had more output under 60hz, which gives it an advantage in output (although it is slight)
The JBL GTO 804's enclosure was a bit smaller, giving it a small size advantage (again, very slight).
The JBL GTO 804 has slightly lower Le, theoretically giving it a faster response/ better SQ (debatable).
The bigger difference here was that the Dayton Audio DCS205-4 8" has an EBP of 86.3, while the JBL GTO 804 has an EBP of 65.8. This suggests that the Dayton will do much better in vented than sealed. The JBL might do a little better in vented, but does just fine in sealed. Personally i prefer sealed anyway.
It's a bit of a tossup, personally I'd go with the JBL.

I would suggest going to the Parts Express Tech Talk forum and looking at the Digger sub.
There are a few other small sub designs there as well.
Regards.

Thanks both of you, that's some useful information and means I may well be able to use the JBL sub instead which is much more readily available in the UK 🙂
I had planned on using a BK Electronics 275w unit (manufactured here in the UK) but I fear the cabinet dimensions will be too small for it to fit!
Is this including displacement of driver for the jbl? What cabinet size with the driver in place?
Is the jbl driver high enough sq for home theatre.

It's discontinued, so maybe ebay?: GTO804 | Powerful & Compact 8 inch Shallow-mount Subwoofer

I thought I found it in the UK but the website that says it is in stock was lying! My thread about this driver is in vain!
Are there any other alternatives in the UK?
JBL Car Audio Vs. Dayton Audio
Car subs usually end up being similar prices regardless of size so if you are after better value buy a pair of 12" divers. (Rockford fosgate do a nice looking one around the £70 mark) JBL's new version of that 8" is available . I'd imagine its specs will be pretty close to the old one.
