Seanheis,
In my view that is a low probability scenario and wouldn't detract me. Don't know why you would ship a speaker.

Is Speaker design evolution stagnant
Based on what I read from speaker manufacturers, many use the same drivers but apply different crossover philosophies to achieve a particular sound.
My simplistic understanding is that while limiting the range of high or low signals , the remaining signal is corrupted ( phase inversions, roll off, etc.. ).
With today’s technology, why aren’t more speaker manufacturers using active crossovers to be connected after the preamp and sending exact spectrum signals separately to be amplified to each driver. That would Eliminate all electronics inside the speaker cabinet except the drivers. Each driver gets fed only the signal that it works best at. No out of phase, half phase, quarter phase issues, no phase angle issues. 100% of the power goes to each driver without limiters to scale it back. I think Bryston Model T Actives is designed this way ( don’t work for them and not pushing any product). Am I looking at it too simply? Do electronic crossover play havoc on signals the way inductors and capacitors do?
Some speaker manufacturers have gone half way with built in woofer amps ( Vaughn?)
Of course you would need a 3 channel amp for each side ( based on W/M/T config) or some variable of mono amps, whatever.

kssst_amojan, I dont want to argue. You are DIY guy and build and rebuild for own use, i hope you sound as perfect as you tell us. is no secret we use high quality amp module from Hypex , it not such expensive and no chip, we have account and get good price. you see on market now plenty accembled amps based on Hypex M-core Some people like it ,some not, but without doubt is best choice to amplified 25-700 hz, The quality , damping is excellent amd price for all parts no more $700-800 per speakers ( no labor cost) FOR mids and high my customers using low power class A (tub or solid state) My personal preference is Pathos double TT 20 Watt per channel.

Kosst, What you describe is true, sometimes. As usual it depends on implementation. Active digital xo aren't that complicated to implement and can solve the issues you describe if done right. At a fraction if the cost of passive. But the system has to be designed to work that way - not just the xo. Why this isn't used more frequently? The learning curve is steep. It's a lot more involved. You need to be able to measure. It's a lot simpler to connect an amp with a pair of wires to the speaker, play music and call it a day. |
