Conrenr Bass Trap Brand Recommendation

[seanwilliamruss]

Just want a cleaner crisper sound without the nasty metallic sounding echo I get in the room (diagrammed below). Really just vocals and acoustic guitar. Do I just need corner bass traps or do I need some type of shield? What brand bass traps (links please!)? Will spend up to $500.

Why are you asking the same question, with the same diagram you asked already in this thread?
