Looking for new speakers for large audio room

TEKTON just intriduced the MATRIX LS @ $18,000....but you have to tie all you furniture down ....stuff starts to move around the room.

TEKTON's Brand new MATRIX LS w/ 15 Beryllium tweeters. Bass you want....you'll have to tie your furniture down......Turn your music up and you could have a "new address"......check 'em out.

sorry 'bout the double post.....I did not think the 1st one went thru.

@ronboco it does, but potentially to an even higher degree as you have elevation in the mix. Also, and is recommended, the crossovers of each are slightly different. Take a look. It’s an expensive endeavor with the Rels though, and the S serie subs are designed specifically for this application. They work fine as singular subs but they are setup to daisy to one another and have mounting plates to tie them together as one. Shocking set up. It is a similar tactic used in live shows where line arrays are pretty much the norm.

Dutch and Dutch 8C. Half of that price range but will beat most. 

But you seem to be just right for Grimm LS1be. Those are endgame speakers.

Time to outgrow all the puerile preamp, DAC, amp banter.
