dhayduk Posted August 31, 2001 Share Posted August 31, 2001 I'm still tweaking my new HT setup and did some playing around with the Large/Small settings. The only difference that I heard was less volume of lower frequency signals, but still some substantial output at 40Hz. Here's what I did (KLF30 upfront, with Denon 5800, which apparently has a fixed 80Hz cross-over): Speaker setup fronts:large (subwoofer on, but physically powered off). Run AVIA left front tones from 100Hz->20 Hz. I saw quite a bit of difference in SPL readings +/-15 dB across that range (room acoustics?). At 40-45 Hz, output was 85 dB. Speaker setup fronts:small (subwoofer on, but physically powered off). Run AVIA left front tones from 100Hz->20 Hz. At 40-45 Hz, output had only dropped to 75 dB. I guess I was expecting a more dramatic roll-off of the lower frequencies, no?? The reason for configuring the Denon w/sub on was to make the conditions as identical as possible - it wouldn't let you configure small fronts without a sub.

sylvester Posted August 31, 2001 Share Posted August 31, 2001 First of all get rid of the denon! I have had nothing but problems with there warranty dept! I had the 5800 to and the dsp chip blew denon wouldent fix it! Beware Quote Link to comment Share on other sites More sharing options...
avman Posted September 1, 2001 Share Posted September 1, 2001 i haven't tried this yet (don't have a powered sub-yet), but i recently read the strda 777 ES rcvr i have (other sony ss rcvrs also??)has a 40 Hz cut-off. if so, i think that would be ideal-where the klf-30's start to get 'light in the bottom' the sub would take over and all would be well in the world-at least the theater room i read the large vs. small setting thread, but this MAY make me re-think the 'all set to small' idea. anyway, need surrounds first, then download upgrade program for virtual matrix 6.1 (yea-that's right-it's upgradeable!) into my 777. feelin'kinda lucky' avman. ------------------ 1-pair klf 30's c-7 center sony strda-777ES receiver NEW! sony playstation 2! dishnetwork model 7200 dishplayer satellite receiver/digital bitstream recorder pioneer dvd player sharp 35"tv panamax max dbs+5 surge protector/power conditioner monster cable interconnects/12 gua.speaker wire surrounds and a 'teens sub coming!
