Is the Infinity Primus sub PS 312 any good. Is it comparably to any good subs from Emotiva, HSU or ED?

I doubt anyone will know anything about this sub. How much are you looking to spend on a sub? How much does the Infinity cost?

Panasonic P60ST50-Yamaha RX-V467 receiver-Sony PS3-Velodyne SMS-1-Canton 430 mains, 455 center and 402 surrounds-Rythmik FV15HP subwoofer- Pro-ject Debut III turntable- I also have a pair of Mark K's DIY design, the ER18DXT's

The PS 312 appears to be a slight step up from the JBL PB12.

Both JBL and Infinity have had serious subwoofer amplifier difficulties (the JBL L8400P is an exception). You should not consider a second-hand model. I have a PB12 that I use in a HT system with another subwoofer but not in my main two systems that use larger subwoofers. You might consider what is listed below.

Two of the recommended subs ~$400 are the Hsu STF-2 and eD A2-300 that do not show some of the deficiencies of lesser-priced recommended subs (i.e., one note wonders or little output below 30 Hz).

Does anyone know the amp type or the maximum volume level for this sub? Also, are there gold-plated terminals?

I realize this is an old thread, but surely someone has had a chance to use this sub for a while and can offer some good ideas about its usage and what wins/fails with this one.

As a quick fail, I just called customer support after sending 3 emails trying to figure out the above information. The call center tech was very hard to understand and kept telling me that he did not have the information. Then, why not give me the number to the people who do have the information?

I haven't ordered it yet

Any feedback on how it performs compared to other sub woofers in its price range ( 399.00)
