Default Tannoy Dual Concentric graphs


I would be very thankful if someone would take a closer look at these graphs and explain the difference.

They both look pretty flat to me but there is quite a price difference so there must be some kind of catch. No free lunches!

Thank y'all.

- the Di6 has an off-axis bloom at 2kHz that might be a bit annoying.

- the DVS8 has higher sensitivity and probably quite a bit higher max. output

- the DVS8 has a crossover null off-axis and the Di6 does not. I do not know why, maybe someone else is more familiar with these drivers and can explain.

The DVS8, per Tannoy's website, is not a Dual Concentric but just a coaxial. Probably with a post-mounted tweeter like their cheaper ceiling speakers. Like a cheap car speaker.

The DI6DC is a real Dual Concentric, with the tweeter mounted behind the woofer and firing through their "Tulip" phase plug.

I expect that the DVS8 is the cheaper of the two, despite having a larger woofer.

I have no experience with the DI6. I have a set of the smaller Di5DC's installed for my upstairs balcony, and they're fine as extension speakers. They do have a midband resonance that's audible in critical listening.

Thanks for the replies.
Yes, they have a plastic cabinets and look cheap but not many speakers comes with the detailed specs like these. You can get a fancier model of Tannoys with similar DC drivers and nice fancy cabinets for twice as much.
But than again - the DI6DC aren't exactly "free". For $350 each.

A coaxial speaker ought to be good in small rooms for surround purposes because the drivers are in phase at the speaker itself.
