Why did you choose this?
Sonic Electronix Store
This tweeter is made my SB Acoustics founded by ex-engineers from Scan Speak. The tweeter based on the SB29RDC tested well by Zaph showing that it has very low distortion (only bested by those costing much more) and can be crossed lower than most anything in this price point (comparable ScanSpeak costs around $250 shipped). Many report crossing this tweeter as low as 2K with a 24db slope, allowing it to be run with some 8" woofers in a 2-way application.

good reviews at DIY Mobile Audio

Wanted a tweeter that can be crossed over fairly low, so I figured I would try these.
Ghion W on Oct 22, 2015
Good reviews. Based on a more expensive SB acoustics tweeter

Does this include an inline crossover or filter?
Jason C on Dec 14, 2014
Best Answer: No but you can purchase the factory crossover with highpass set for 1500Hz.

This will allow you to integrate the NVX XSP65 Woofer at a later date if so desired.

What are the dimensions of this tweeter? Specifically the depth(not looking to top mount it), the diameter with and without the flange, and the cutout diameter? This will determine if it will fit in my install.
A shopper on Oct 28, 2015
Best Answer: Go to the SB Acoustic website, and lookup the SB29RDNC tweeter. There is technical drawings of it available for all dimensions, which are identical to this model. The only difference is the flange ring which may be smaller on the NVX one

Does the flange mount come off of the tweeter so it can fit into a factory sail panel location? If so, could you please provide the dimensions of the bare tweeter without the flange? Thank you!

Best Answer: The fang does come off if the tweeter. Not to sure of the dimensions without the flange but it's still pretty big. Well worth it for the sound it produces.
