Ciscokid Posted December 24, 2003 Share Posted December 24, 2003 Hi, I am playing around with the speaker level I/O on my ksw12 and wanted to know how this type of connection works. - Is this a passive type of connection? - How is the low frequency pulled out and passed to the sub amp? - Any changes to the single passed on to the main speakers? Thanks for any help on this subject. Regards, ck Quote Link to comment Share on other sites More sharing options...
gcoker Posted December 24, 2003 Share Posted December 24, 2003 In using speaker line inputs you are basically running your main speaker output through your sub. Based upon the cross-over set on the sub it will pass on the frequency above the setting you select. Your sub's amp will take the balance frequncy and amplify. If the sub is not turned on then all bandwidth will be passed on to your mains. If you connect your sub through the LFE output on your reciever then the receivers internal cross-over will direct the low frequency to your sub. The subs internal cross-over is by-passed.

Ciscokid Posted December 24, 2003 Author Share Posted December 24, 2003 Any info or specs on the crossover? Frequency range, db loss, distortion? Would Klipsch have this info? Regards, ck Quote Link to comment Share on other sites More sharing options...
gcoker Posted December 24, 2003 Share Posted December 24, 2003 Klipsch web site should have most of that info. In terms of cross-over the range on most subwoofers are 35-100 hz. Typically you set that to the lower range of your main speakers. For example, if your main speakers have a range of 45hz to 20,000 set your sub's cross-over at 45 so that anything below 45 you sub will handle and anything above your main speakers will handle. If you have small bookshelf speakers you probable want to set it at around 80. It reallly boils down to your preference. The higher your set the sub cross-over the more bass will be produced from it.

Ciscokid Posted December 26, 2003 Author Share Posted December 26, 2003 Have been listening to my 300B monoblocks, ksw12 & heresy's using high level I/O. Really like the improved base. However, am wanting to experiment with running the sub in parallel with the mains and wanted to know if doing so would affect the impedance seen by the amps?

Ciscokid Posted December 29, 2003 Author Share Posted December 29, 2003 Just an update.. After listening to my system with the sub connected using the speaker level I/O (amp-sub-mains). Things just didn't sound "right" (if you will). The bass was much better, but the highs seemed edgy, mids not as sweet, presentation seemed less focused. As an experiment, I reconnected the sub in parallel with my mains. Ok, now the mids and highs are back with the added benefit of bass, soundstage and presentation are better than ever.
