Typical New Speaker Dealer Discount A Buyer May Expect

I'm searching for new speakers and am willing to spend around $7K to $8K, or so.  I'm wondering if that amount generally represents a final discounted cost off MSRP of $9K to $10K, or 15% to 20%?  This figure is what I've estimated based on a number of member comments in terms of new equipment discounts.  Do discounts vary significantly from dealer to dealer, speaker brand to brand in this price range?  This will help me in terms of budgeting and in terms of which speakers to begin the process of narrowing down for final selection, and whether to purchase new or used.
