have a pair of Tekton Perfect Set 15s but need a lighter speaker

Any speaker that is as sensitive as the Tektons won't be much smaller.  If you like their sound , get some of those heavy duty furniture slider pucks.   Put one under each corner.  

Lejan, 

Do they have spikes or are they threaded? 

Google "Herbie's Audio Lab." Look for their Cone/Spike Decoupling Gliders. They also have gliders that replace spikes as well with threads. 

Will make moving the speakers significantly easier and you get to keep a sound that you enjoy (most important part). 

@69zoso69 might have a suggestion. I think he has similar speakers.

Hello @lejan 

I have a pair of the 2-10s on Gaia IIs. Tekton offers surprisingly good sound for the price point. 

To play with placement I put them (and the gaia's) on washcloth so I can easily slide them around on my wood floor. Once I  get the sound dialed in I simply remove the washcloth. 

I suppose if you're on carpet none of this helps. 

Coincidently I have a Decware Zen 25th on order (arriving sometime this summer/fall). 

Cheers. 

The white plastic furniture moving discs HD or Lowe's work reallywell and are very inexpensive.

That said, a pair of Monitor Audio 300 7g at $2850/pr. are Stereophile Class-A rated, have half a dozen other international awards, are fairly easy to drive with  90.5 dB 1W/!m sensitivity and a max in room output per pair of ~117dB.  They  only weigh 49 1/2 pounds each.  Their little brother, the Silver 300 give up only a couple dB sensitivity, max output, a few Hz of bass, and weigh in at a svelte 42 1/2 lbs. I have the 300s and am extremely pleased with their musicality, range, soundstage, clarity, and dynamics. As a bonus their dual rear ports may be stuffed for final tuning. in my room, I have to place them within a couple feet of the back wall,, and stuffing the lower port only clears up any 'chestyness' on male and female vocals without sacrificing any bass.
