passive sub recomendations? - Blu-ray Forum

jdc115 · 12-23-2008, 02:08 PM

I have an old M&K sub but the drivers need to be replaced which are quite hard to find at the moment plus I would have to get them shipped overseas so maybe not so cheaper either.

since I have a spare Parasound power amp (125 watts/channel), i could use the sub outs on my processor to feed this power amp to a passive sub. I am thinking this might give me a more economical, higher quality sub if I could find a good passive subs.

Does anybody have suggestions or used any passive subs with an external power amp?

Thanks for any recommendations, would like to find something under $500 but will always consider something higher if worth it.

SVS makes passive cylinder subs. I have not used them, but I do have one of their powered subs and it is wonderful. Check them out here:

Yeah, I'd get this SVS. Also check out Audiogon for some good deals on used audio gear.

thanks, it looks quite promising. Going to try to find the mid one that extends down to 20hz. Just remembered that I can also bridge my amp to I believe 250watts as well so would work very well for a single sub

Big Daddy builds passive subwoofers. Read my thread on Repairing, Upgrading, & Building Subwoofers You will see how easy it is to repair your subwoofer or build a new one.

Home Theater Direct also sells passive subwoofers, but I believe the external amplifier is included in the price. They come in three colors: Black, Dark Cherry, & Light Cherry. They have 5 year warranty with 30 day home trial. I don't know about international shipping.

Level Three 12", $429.

Level Two 10", $349.

Thanks Bigdaddy, I am reading through your thread. Glad to have many options.

My Gallo Reference 3's have a second bass voice coil that extends the bass from 32hz to about 27hz I believe. It is made to be used with a special bass amp from Gallo but I currently feed to sub outs to my Parasound amp and connect to my speakers bass binding posts. The results are not bad but not quite like having a true sub woofer.

My second thought was to replace the drivers in my M&K sub but I am having a hard time finding 2 8ohm, 8" M&K drivers. There seems to be plenty of 4ohm drivers but since this is s push/pull design, it needs 8 ohm drivers which then give the amp a 4 ohm load.

But the M&K only goes down to 27hz as well, so I just now thought about find a passive solution to use with the Parasound amp.

I'll check out the links you provided as well.
