I recently bought an alpine type s SWS-1242D (dual 4 ohm) and after looking in the manual I found that many of the t/s parameters are "To be announced".

Basically alpine didn't ut down the T/s numbers and I can't find them anywhere. It wouldn't be so bad but they are missing Qms Qts Qes.

I have always used winisd to build my boxes that fit my situation, but with the lack of parameters It won't work. Does anyone have the T/s or know if older models t/s will be similar?

Does anyone have any suggestions about the box size? I'm going for SQ with this sub so I'm goin with a sealed setup. Thanks

The link didn't work. I'm not looking to buy the sub, I'm looking for missing T/S parameters that alpine for some reason didn't want to include in the manual.

Thanks for the help. This seams to be for the newer model type s, though it atleast gives som info on port length which is helpful. You'd think with Alpine being generally known for SQ they could atleast offer the complete T/S parameters instead of saying "Check our website for updates". How can you write that in an manual?

I would try to phone customer support or send them an email if you didnt try that all ready.

UPDATE:

Alpine is worthless when it comes to customer service. I asked for the missing parameters and they basically told me to build a box of 1.25Cubes. They wound't give the the specs I need (QTS, QES, QMS) and basically brushed me off. how the **** can you build a sub and not include or have those specs?

Thanks for nothing alpine
