Thanks "dgage"! No offense taken on your comments. I know I'm the newbie on this forum and must earn my respect.
I apologize if I offended anyone with my opinion post. I'm a vintage audio guy, who enjoys a 2-Ch Stereo Setup. However, my clients like home theater systems with 5.1 to 7.1-Ch setups.
I know and understand that there are more powerful sub manufacturers in the industry than REL & SVS. I'm not here to dispute which subs are the best, or sound better, or more powerful, etc. Every person experiences music differently, and have their own sound preferences.
I created this Forum Topic for some insight and ideas for building a nice sub cabinet for the driver. I know I'm not going to build a REL sub box that matches their sound quality. I'm doing this project to challenge myself and become more familiar with building subwoofers & loudspeaker cabinets.
Thank you for the feedback.
