This is my first 5.1 home theater, but I'm no novice in sound systems configuration. I've been in car audio for 15 years now and a big audiophile. So, I know the kinda quality I'm expecting outa my HT and have tried all possible crossover settings, but it's way below expectations and gives poor LFE and Bass Management. OK lemme explain the stuff I have. Bedroom Dimensions and Dynamics 1.16' x 12' / Concrete flooring but wall-to-wall carpeted and drapped windows 2.Front speakers (Towers) are 51/2 feet apart angled in about 20 degrees toward the center of bed where I rest my head while watching movies. Sub is placed about 6 inches to the right of the front left tower speaker. Center speaker sits just below the Philips Ambilight 7803 and is equidistant from both tower speakers. 3.Front towers are about 6 inches away from the wall behind and sub is about a foot. 4.Surrounds are slight above the listening position on the side walls. 5.The front edge of bed is about 3 feet away from Towers/Sub/Center. Bed is not solid wood and the front side of it runs all the way down to the floor i.e. there's hardly 3 inches space under it. System Description 1.Yamaha RX-V363 AV Receiver with YPAO / 100 Watts per channel x 5 2.Front Towers: Yamaha NS-7900 2-Way Bass-Reflex / 100W/180W Nominal/Max input / Frequency (32 Hz - 25 kHz) 3.Center & Surrounds: Yamaha NS-P60 Center: 60W/180W Nominal/Max Input --- Frequency (70 Hz - 30 kHz) Surrounds: 50W/150W Nominal/Max Input --- Frequency (80 Hz - 30 kHz) • 4. Klipsch KSW-10 Powered Subwoofer. • 5. DVD player is Pioneer DV-410V. • 6. Wiring: All speakers connected with $160 high-grade 12 AWG wire. DVD player is digitally coaxed into the digital input on AV receiver with gold plated RCA terminals. Sub is also connected with digital coaxial RCA cable with gold-plated terminals from digital out on the AV receiver into the Left (LFE) female slot of the sub. •Current Settings 1.Gain on sub is at 8. Crossover settings are bypassed on sub by keeping the knob on max i.e. 120 Hz 2.Front Towers are set as LARGE rest all as SMALL. 3.Crossover on receiver is set at 60Hz. It offers (40/60/80/90/100/120/140/160/180) crossover options. 4.LFE/Bass out set to BOTH. I've tried setting all speakers to small and LFE/Bass Out to SWFR and setting crossover at 100Hz, but it didn't sound as good. 5.LFE is set to max i.e. 0 db. Options are from -20 to 0. •Problem 1.The bass and LFE are localized and lack the rumble and thump. For example, gun shots sound like crackers on a 2 years old kid's birthday party. Tested on Saving Private Ryan (First 3o minutes). The closing of car and room doors lack bass depth. It should sound like a sand bag dropped but it sounds like an egg thrown on the floor. I have tried changing the placement of sub but to no avail.
