I owned these speakers M7si, and the M5si bigger version years back and they are nice sounding speakers for their time and price point. They are definitely NOT lacking bass regardless of placement or amplification. The upper bass is no doubt tipped up. Either deal with it or move on. They are no worth much money today anyway.
I sold my mint pair via Craigslist for $150 the pair and it took almost a month even at that price. Best of luck!!!
