Hello, Rick.

I've got the usual questions for you:

Which midwoofers are these? What size?
Specs?
Sealed or ported?
Impressions?
Price?

Thanks!

Michael

Here are the measurement graphs. 1/12 octave smoothing but no gating so there are some effects from the room.  Gating makes everything above the frequency look more pretty but you lose the low frequency resolution. The nearfield bass curve is more anechoic and minimizes the room effects to show the true bass extension.

With 92dB sensitivity the 4 ohm (nominal) and 3.6 (minimum) impedance isn't difficult to drive.  Very smooth response curves, both horizontally and vertically. The 200-250hz dip is the floor bounce (reflection) that's typical of a stand-mounted speaker. The vertical curves were taken on-axis with the tweeter, midpoint of the tweeter and upper midbass, and on-axis with the lower woofer.  Uniform vertical behavior with a MTM using midbass drivers this size isn't easy to achieve!

Most of the information was added to the second post I made. AudioTechnology 15H520613SDKAM (6") with a sealed box. These are designed  to mate with a larger woofer which is the application that the owner will be using. $5,500/pr. delivered to the CUSA.

Biased impression? Very neutral, clean, great sensitivity... :thumb:

Rick,

Thank you.

For my reference, what price would you charge for just this sealed MTM design (assuming standard veneer and assuming they'd be paired to a pair of Rythmik F12G subwoofers, for example)?

Regards,

Michael

Same cost - you'll need to have a high pass filter and woofer with enough bandwidth to cross higher than a standard subwoofer crossover point.

Ah. I should have phrased my question differently. Let's imagine a similar speaker design as the Etereo, but the midwoofers employed in the MTM are the 6" Satori drivers (as in the Decenio). How much would this variation cost?

About $3,800 to $4,000 for a pair delivered.
