meuge Posted June 20, 2006 Share Posted June 20, 2006 I was wondering how complicated it would be to build a simple, non-adjustible 24dB/octave or steeper crossover to use a subwoofer in a 2-channel system. I am using the Outlaw ICBM-1, and I am happy with it, but there is a little bit of insertional noise (noticeable with tube preamps) and some loss of soundstaging. I figure this can be minimized with a simple crossover built of really high quality parts. If someone has done this, or knows somebody who has, let me know. Also, if you think it's better to just purchase this equipment, suggest a piece or two. Thanks. Quote Link to comment Share on other sites More sharing options...

meuge Posted June 20, 2006 Author Share Posted June 20, 2006 I do not know whether it should be active or passive (somehow I think that steep crossovers are likely to be active), but what I am sure of is that I'd like it to be line-level, as opposed to speaker level... something I could put between my preamp and amp.

I have an amplified subwoofer right now. I am very satisfied with its performance... I just wish I could get rid of the insertional artifacts that the ICBM is giving me. I do not need its multichannel capability, nor the myriad of its adjustible functions. All I need is for my line-level signal to be cleanly segregated between my speaker amp and my subwoofer amp, based on the frequency. Thanks for your replies, btw.

Thanks for your replies, btw. so you need to by-pass your existing internal amp circut. are you handy enough to replace you existing sub woofer internal amp with something like the below? http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=300-784 or http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=300-796 Quote Link to comment Share on other sites More sharing options...
tofu Posted June 20, 2006 Share Posted June 20, 2006 meauge, i'm looking for a crossover solution as well, so i'll keep an eye on this thread. the only other thing i've come across besides the icbm would be xm1's Quote Link to comment Share on other sites More sharing options...

When I said my subwoofer was amplified I meant it has its own amp (the PartsExpress 1000W), not that it's running off my speaker amps. P.S. The sub is the Titanic III 15" Quote Link to comment Share on other sites More sharing options...
