Lapierre,
Through the years I've positioned Bass Busters in the four corners of the room. Other than that, speaker placement has helped with controlling the bass.
The Volti is ported in the front of the speaker and have proven more flexible with the back wall placement. Bass performance has proved to be dynamic,resonant and articulate with these guys.
The Signature amps are very limited production made in Milwaukee and were probably made about 15 yrs ago. They are unusually a FET input and a tube output (4 - 6550) - About 150 watts. I really was concerned about their ability to cleanly and qualitatively feed the very sensitive Alura. Fortunately they do. Maybe some day I'll look into SET amps.

Dave do you think you need to make any adjustments for low resonances?

Never heard of the signature technology power amp. What year is the SRa-9m?

Enjoy.

Bulging beauties with burnished bumping bass. I woke up with a strong desire to use my b's. Say it like Cosell. Heard this system a few days ago and I can honestly say it caused insomnia...I plotted into the wee hours of the morning what combination of bank robbery and penny stock picking could win me these speakers!

Thanks Catfish. The living room dimensions are 21 X 13 X 8.5, not counting the window bays. Our house is 95 yrs. old and has plaster textured walls and a coved ceiling. If it's true that the room plays up to 50% of the sound, then the system is really affected by this construction.
The Volti Alura is truly amazing and unlike 95% of traditional driver speakers. Yet it has no "horn" signature other than providing a huge sound-field.

Fantastic system.

Congrats on the new Volti Alura. Beautiful speaker.

Awesome system. I'm looking forward to hearing the Voltis. Can you tell me the dimensions of your room? You have done a beautiful job with the aesthetics.
