Laying the HWK down TS parameters
06/23/07 at 16:43:14
 
Thanks for all the support. More questions:
When using the HWK 18 can it be used horizontally? If so could/should the two ports be facing up? What testing bits and peices do I neede I have heard the Mach 5 18" driver will work well. Are there Thiel Small parameters mentioned somewhere for the HWK 18 that I have missed? I see specs for the HWK 15.

The parishioners are looking ay me sideways for building this sub but the new organist is very pleased. Roll Eyes

The HWK design began with the 15" woofer. The design is a very forgiving and specs should be taken into consideration but not manditory. Look for a 18" subwoofer with good X-max (12mm to 20mm) and Fs around 27Hz to 20Hz or lower should be more than enough to do damage to its surroundings. MACH 5 AUDIO woofers are top notch. I have two of MAW 10s that I purchased for $30 ($20 shiping). A woofer of the same build quality (in the U.S.) would prolly cost over $100 easy. You can't go wrong with MACH 5 AUDIO.  If you need more info let me know.

build it to plans, dont change anything, use good drivers and a good amp and it will work well.

it can get down to 13 hertz.
