Older subwoofer specifications

Those drivers can be abused pretty fine. It are SPL/SQ car subs. I didn't try it out back then for no reason. I had these subs. I asked other audiophiles on other forum that no longer exists. They did the math back then. They did calculations. They told me with dsp and such you can flatten the curve nicely. They need some juice. And they should do pretty fine in smaller room. And ofcourse not comparable with a dedicated HT subwoofer of similair price range. But I had these already. So they did cost me nothing at that point. I just needed get sealed eclosure cause no way these can be in a decent size enclosure ported for HT.

And it proved to work fine. I reach enough in the low end in movies that you feel it without hearing.

I'm glad you're getting what you want out of the them. I'd look at a tranform to extend their low end below their f3, that is really the only way to get a sealed sub, one designed for car audio, to below that. There are not a whole lot of subs that can do this without creating other issues.

Here is an price example of this.

Ye I know. These can move enough air in the small audio room I have to be useful enough. I not want other subs cause I will barely use that very low end on high volumes. I checked yesterday and 20Hz tone can be felt pretty good. 15Hz still feel it but thats where the amp gonna struggle delivering the watts.

Guess the whole reason these speakers can do it is cause they are SPL/SQ car subs. linear xmax is 17mm. In car I just didnt reach 160dB with them. I think was 158 or something. So they have seen abuse and still work fine. I just need be careful to not have over excursion in the low ends. That might be bad for them. But seems my amp is preventing that cause of clipping. So I think it is pretty good set up.

All it cost me 12 years ago when I made the first enclosure for the subs was like 300 euro for amp and dsp since had these subs already. I don't think I could get better clean and accurate bass for alot cheaper back then. And not now either. Especially if take in mind the small enclosures.
