Every Altisonus speaker ships without a passive crossover. Because crossovers are compromises. If you want one amp, one cable, one and done, buy someone else’s speaker. If you want to hear what your amplifier actually sounds like, keep reading.
A passive crossover is 40 parts between your amp and your driver. Resistors burn power. Capacitors smear phase. Inductors saturate. You paid for a $5,000 amplifier. A $2 crossover just edited it.
Altisonus uses active crossovers before the amp, or no crossover at all. Each driver gets its own amplifier. Nothing in the signal path except wire. That’s why I require biamplification.
Vent alignment tolerance: 0.5mm. I’ve rejected cabinets for 0.6mm. Not because you’d hear it. Because I would. Each mirror-image pair is cut from the same walnut slab, book-matched, then tuned to your specific amplifier and cable. This is not production. It’s commissioning.
No dealers. No showrooms. No 5-star reviews from magazines we paid.
No “house sound” tuned in a boardroom.
No MDF boxes wrapped in vinyl pretending to be wood.
If you need the safety of a recognized logo, we’re not for you.
If you want the speaker your neighbor hasn’t heard, and your system isn’t ready for… welcome.
You call.
We talk about your room, your amp, your cables, your music.
Then you come to Bonner Springs.
We tune a pair to your gear.
If you buy, we ship.
If you don’t, the whiskey’s free and you still learned something.
Each commission takes 8 weeks.
I build 6 pairs a year.
When they’re gone, they’re gone.
I’m Kermit. I built Altisonus because I was tired of apologizing for physics. Established brands sell heritage. I sell performance. If that sounds unorthodox, it is. The laws of acoustics don’t care about your logo. Neither do I.
No shortcuts. Ever.
