I hear everything. Great for music and movies. They are fantastic at all sound levels from quiet to ear splitting loud and are crystal clear. Go great with the Logan stage mid channel and the Logan Depth i sub woofer.

These Spires are great with my music and I'm shocked how great they improved my 5.1 system the movies are awesome!

I am amazed at the imaging, and clarity of these speakers. I was a fan of Mirage products, and the depth they provided. The Spire's easily match the depth of their sound, and have even more lower end punch due to the powered woofers. Beyond the sound, thees speakers are elegant and an art statement in themselves. It is a pleasure to walk into my family room and see and listen to these speakers.

Cheers to Martin Logan.

I have been on Martin Logan journey since college days. It all started with Aerius i's and Cinema Center Channel.
Last year I bought a pair of Vantages. From Aerius i's, they were a great improvement. More airy, deeper bass, and the craftsmanship improved dramatically over the years.
I am an somehow an oddball when it comes to music. I love classical and electronic techno music(I know, I am strange). Techno music has lots of electronic bass to test out the woofers.
I saved hard and attempted my final upgrade of my life, and were the Spires.
As I am typing these words, and I have been listening all day. I am in musical nirvana. I am so much happier with the Spires over Vantages. Don't get me wrong, I loved the Vantages, but now the Spires, it's another level up. Maybe it's those crossovers Martin Logan constantly talks about.
Bigger panel with more surface area music seems bigger. And there's bass! Oh man, there's bass! Very articulate tight bass! I think the sealed enclosure helps big time.
Personally if you can afford upto Reserve ESL series, I think Spires are THE BEST bang for the buck speakers for the money.
I personally never heard the Summit X's(Way out of my range), but they have the same surface area of the panels and woofer size(Although it has 2 of them). I am guessing that it's not as jump from Vantage to Spires. I wanna hug you Martin Logan engineers! Thank you so much for such a beautiful and wonderful sounding speakers! They are a keeper!

The Spires have proved a revelation. They adjusted in my living room's odd acoustics perfeclty but, more importantly, they managed to bring the best out of my Esoteric DV60/Jeff Rowland Synergy / 201's system. The Spires exhibit great soundstage, they are analytical but also very sweet sounding. What a great buy!

The Spire is the best speaker Martin Logan has come out. This Speaker is the Ultimate choice for Classical, Jazz. Add a Sub woofer and you have a speaker for Rock Music.

My System Consists of:

Spires - Speakers.
CD - ERC-1 (Emotiva).
Pre-Amp CPA1 Balanced (Cary Audio).
Power Amps Monoblocs XPA-1 x 2 (Emotiva).
Grotto-i Subwoofer (Martin Logan).

Sounds like a $ 100,000 System.
