I've always appreciated just how good Totem is at getting deep bass out of the smallest boxes. I really can't afford nor do I need any new speakers, but did have a need for a compact sub to fit in a tight space under my workbench at my job. I work in an R&D machine shop and it's just me and 2 other guys, both of whom come in earlier and leave before me. That gives me time to enjoy music while programming machines or handling documentation that goes with the territory of medical device R&D. I picked up a pair of KEF Egg powered speakers, and they're terrific for what I needed but sorely lacking bass.
Knowing how good the Totem Kin and Kin Mini subwoofers are and that they fit in the 10" deep space behind the foot brace of the workbench, I went looking for a used one. That space is tall, 34" wide, open above a 24" tall wall. I could not find an affordable used one, in fact the only used ones I could find were in Canada. I did find a Dreamcatcher sub on eBay, cheap. The seller referred to a buzzing noise but I figured I could ignore it, get a new amp, or get it fixed. Turns out I couldn't ignore it. Ugh. Totem says "discontinued, no parts available." A friend who repairs pro audio gear (warranty for Marshall, Mesa-Boogie, Roland, etc) agreed to try. With no schematic of the DSP, he couldn't.
No amp I could find fit the 6" x 6-1/2" place on the sub. Even the close-size ones were well under the 200w rating of the failed Bash amp. I capitulated and went with the Dayton Audio SPA250DSP plate amp as I have one on another (M&K V-90) sub and it's incredible, just $179.99 with free shipping. Added the matching frame box for $32.80. I had put a plate of the same over the back but below the twin ports. That meant the plate amp now hung below the bottom of the sub's cabinet. I had my son build a 3-1/2" riser out of 1/2" MDF, and it's now all dialed-in perfect. I'm still in for under the cost of a used Kin or Kin Mini with a total of $306.80, so not unhappy. And man, does this sub kick ass for it's size! I now have people from all over the facility (over 600 people there) coming to hear this, and all are shocked. I'm just smitten.
