10 inch Response Titanium finish subwoofer

Jaycar Part no: 2274 - Cost $49aus (Runout price 5th May 2005)

This is the driver used in most of my projects to date.

It is currently being phased out in favour of the dual voice coil unit

Here is my parameter file for this driver for WinISD Pro ver 0.50a7

 

Suggested designs

Jaycar Design 48 litre box tuning freq 26.5hz One 66mm port 270mm long

My Design

50 litre box tuning freq 28hz Two 86mm ports 814mm long

I agree with Jaycar's design except I specify larger ports

SPL

Driven by 80watt amp

Jaycar design in red, mine in green

 

Cone excursion

No problem here

 

Port air velocity

Jacar design will probably be too noisy for Home Theatre environment

Port flares would be required - see the note at the bottom of this page

 

The design I have presented here is covered in more detail - see the "Snorky" page.

For a dual driver setup using this driver see the "Blast Furnace"

 

Port Flares - calculated with Flare-it

I would recommend 15mm flares. If you have a full size router, you can use a 19mm rollover bit for routed flares. If you have a small router, you could probably get away with 13mm flares.

Alternatively, you could move to heat molded flares in 20mm or 25mm radius.

The intake could be flange mounted with a 13mm routed flare or you could fit a donut ring . If you are using a heat molded flare, you could do a one-piece design with a 20mm flare on the inlet

Depending on the flaring options, you'll need to adjust the physical length so that the effective length is as shown above. The port flares page has a section on calculating effective length as well as some information on availability of commercial flares.
