Oh boy! I knew two RS18 DIY suggestion by Jay1 will have a huge momentum around here. I also know that if I build Daytons, the final product will look disgusting in my living area (relatively speaking vs 15H or other ID subs; I suck in finishing touches) and won't have any WAF at all. In addition, I don't want to overwhelm this area with giant subs. Sure, it will happen one day down the road but for the basement when I have 50K to finish it or sooner if I get enough info and courage to build two 18" Daytons for my HT and replace my beloved H100. BTW those 18" subs are OOS on partsexpress and are close to $300 ea by the same guys on AMZ. Most suggested flat packs for 18" are OOS too. So a single 18" with amp ($275 or more), MDF (2 sheets $90), laminate (??), small parts (??) etc is not gonna be far from H15. While rummaging thru DIY forum, I also come across rattling noises and other issues with DIY subs and although its kinda labor of love, most look ugly (again relatively...). However, I do want to ask Dr HSU what he thinks about a DIY Dayton 18" vs his H15. Also, I would appreciate more opinions of members before making a purchase. Is there a good dumb proof video on a large DIY sealed sub?
Also saw somewhere that a near field placement of an underpowered sub can be beneficial in large areas and there is enough room on the left side of the sofa for one big sub where it will also be in a corner.
