Author Topic: Speaker Position Amanda Mundin Expert Film Handler Posts: 122 From: Belper, Derbyshire, UK Registered: Sep 2005 posted 11-09-2005 01:36 PM                     I ask about Subs as using Dolby Tech Guidelines i figured out 1 4642A would be enough for my auditorium as its quite a small house, so I wondered if using 2 taking half the load each but being separated would distribute the bass better. Also regarding stage speakers is the fall off in level, and the fall off in HF on L+R when the masking comes in for 1.85 or 1.66 noticably different, even with acoustic masking?  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 11-09-2005 05:41 PM                     There is some loss of HF even with tranperent making material but very little I usually put the L and R just inside the 1.85:1 image edge  |  IP: Logged Alex Grueneberg Expert Film Handler Posts: 125 From: Chicago, IL Registered: Aug 2004 posted 11-10-2005 06:16 AM                        Steve, you are correct. Sorry about that, bare with me I'm still learning about all the models. Ironically I thought I might have been incorrect and had some free time earlier today waiting for a print to arrive. I opened them up to check the back of the driver, sure enough 4645. I'll update with my room dimensions and amplifier specks tomorrow.  |  IP: Logged Amanda Mundin Expert Film Handler Posts: 122 From: Belper, Derbyshire, UK Registered: Sep 2005 posted 11-10-2005 12:16 PM                     Thanks for the help, also can anyone confirm the distance between the front of the HF horn and front of the LF unit on a 4675C-8LF?  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 11-11-2005 11:22 AM                     I wouldn't worry about the "correct distance" if you use a variable time delay adjustment crossover like the Rane it is a non issue If it a non adjustable set it for the distance that the delay is fixed for to correct the phase at the crossover  |  IP: Logged Amanda Mundin Expert Film Handler Posts: 122 From: Belper, Derbyshire, UK Registered: Sep 2005 posted 11-11-2005 12:40 PM                     I was thinking of putting the speakers in a Baffle Wall and assumed that the front of the LF driver should be flush with the Baffle front and just wondered how much further forward the HF driver protrudes, in terms of how far forward the screen sheet would need to be from the Baffle?  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 11-12-2005 02:12 AM                     the bass cabenet should be flush with the baffle wall and the horn placed where the phase alignment of the crossover is designed for  |  IP: Logged
