Understanding subwoofers

[sigbergaudio]

That’s exactly why I’m cautious when it comes to niche manufacturers. The real question is: what can they do better than the established, reputable companies? Why should we pay such high prices for something we could get for 20% of the cost?

That is a whole other discussion entirely. And I don't think you will find that many niche manufacturers that build their own drivers.

Since you implied we were using cheap bass drivers earlier, the drivers in our subwoofers are from Scan-Speak.

I’ve seen your Scan Speak Chassis, and you can rightfully be proud of it — but what about the others? Probably not so much. You know perfectly well how critical a perfect diaphragm is in the 100–1000 Hz range. That’s where precision really matters.
You’re using DSP anyway — so where’s the problem? I’m talking about cardioid design

I'm not following you. "What about the others?" Are you referring to my other speakers or drivers, or other companies?

I agree a good driver is important in the 100-1000hz range as well, yes. Have I said anything to imply otherwise?

DSP cannot fix a poor driver.

"I'm talking about cardioid design" <- I'm not following.

Why do you use such an ugly PA loudspeaker for the bass in the MANTA Cardioid Active Speaker system, with that obvious metal basket and no grille to cover up the primitive sealing ring? There are nice 8" drivers available, like from SEAS, with cool motors and graphene or plastic cones, like the U22REX. I know you need a bit more excursion, but why don’t you ask Dr. Müller and build yourself a proper bass driver for the MANTA?

You may have to change threads as the driver materials discussion is off topic and Sigberg’s specific implementation is best done in the Dealer topic area…

Yeah, don't get Norwegians angry. They'll come after you.

I answered in the Manta thread to avoid derailing this thread completely. Those who want to follow that discussion, my reply is here:

Sigberg Audio Manta (12" wideband cardioid active speakers) development thread

When they produce around 500,000 speakers of a particular type, they can be made affordably, but that doesn't necessarily mean they are of poor quality. They actually have a substantial R&D budget, something like $500 million (Home Entertainment). Sure, but if they have a front port that isn't...

Sounds like you need to start manufacturing speakers?
