Sorry, what I meant is how does the treble response of the speakers sound to you?

Recently me and my wife refurnished the living room and there is now space for a home cinema system again. Material is 18mm baltic birch plywood, finished with high gloss varnish. Drivers are SB Acoustic SB19ST tweeter, SB13PFC midbass, 2x Reckhorn D165 subwoofers per tower. Crossover between tweet and midwoofer is 2,5kHz, 85Hz between midwoof and subwoofer. Total system is 4 subwoofer/speaker stands as a multiple distributed subwoofers, 5 identical speakers as mains. Overall system bandwidth is from pretty even from 30Hz to over 20kHz. The center speaker is on the TV stand. The receiver is Marantz SR5010.

Very decent looking speakers. Too bad photos will disappear when the link dies. Would be better to attach here.

This looks awesome!
Much like my own system. I've built some speaker stands/subwoofers too, one on each front channel. Although they turned out a little too big. They might have been 10 - 15 cm lower in hight, or some 10 liter smaller in net volume.

They're an active sealed system, based around a Hypex nCore amp with DSP (11 biquads per amp channel) and a Peerless XXLS 12 driver. 41 liters net volume.

Mains are Dynaudio Special 25's, crossed over at 80Hz. Subs cross over at 120Hz. Integration between the two is phenomenal!

In theory the total system response should be flat to about 16Hz in room. Measurements cannot confirm that with certainty, but they do get pretty close to 20Hz with authority.
When I have enough time, I'll do some more measurements and tweaking.
