Suprising winISD results?

[Thixx 10+ year member]

Alright I've been putting a lot of different subs into winISD to compare them and a few I recently put in where the AQ2.5, Audiopipe DMZ12 (bling bling) and SSA Icon 12. Heres the graph. All are in a 1.5cuft sealed box and all are 12 inch subs.

Red/Pink:Audiopipe DMZ12

Orange:SSA Icon

Yellow:AQ2.5

Is winISD not as accurate as I've been thinking or is Audiopipe better than I thought.

just because it models up well on win isd. IT WILL NOT model the same in car

audiopipe doesn't post accurate T/S parameters. The numbers they show aren't even physically possible when you calculate the unknowns from given known parameters. I think their effeciency is an in car estimation lol. So no, with the audiopipe you can't trust the T/S hence the models won't work.

and the SDC was NOT designed for sealed enclosures...

If you want to go sealed, look for a driver with a higher Qts - ~0.5 and higher.

Looking at the SPL graphs is pointless for relative driver output as the output spl graphs are purely based on the sensitivity of the driver. The reason it has better LFE is based around being more suited for a sealed enclosure. The more suited for a ported enclosure the driver is, the worse the low frequency extension will be when sealed.
