Re: SDX15 Mk II

How about the inductance? Is there still a demodulating circuit?

Any chance that you will publish the klippel results?

Tentative pricing?

Hi,

There is a shorting ring; what would you consider a good inductance figure?

When the driver is reviewed in Voice Coil there will be a Klippel report.

Until we have full specs I think it's a little premature to quote pricing. What would consider fair?

Re: SDX15 Mk II

Hi Bob.

Well...I don't know...all of that sort of depends on the final parameters and Klippel report in my view. The $250-$350 range is hotly contested so you'd probably want to land in the midst of that if it makes financial sense.

I am a Voice Coil subscriber, so I should see the report if it is one of the regular test reviews.

Inductance linearity over range of stroke is what I'm interested with more than a single data point, which is of much less value and information.

Re: SDX15 Mk II

That sounds like an awesome driver. Can't wait to see this one.
34mm excursion for a 15" driver is alot and massive power handling.

cheers

Re: SDX15 Mk II

i may have heard rumours about what this thing can do, and i am seriously considering swapping out my SDX15 for a mkII. LOL. or i might just have to build a second one....

Re: SDX15 Mk II

I built a LLT sonosub with the SDX15. Will I be able to swap in this driver or is the mounting completely different?

This is pure speculation on my part, but I reckon a straight swap would be entirely possible. However, I would speculate the new driver would probably need a slightly different cab for optimal performance, and although it will probably work fine in your existing cabinet, the differences or performance increases would probably be too insignificant for it to make sense from an economic POV.

Thats my first thought on it anyway.

It will be nice to have zero inductance, but that can not happen yet.

A fair price is about the cost of a Exodus Tempest X2 or a few US dollars than that.

One thing that will be nice is the efficiency be at least 88 dB. Sure you stated that the SDX15 Mark II can handle 2000 watts, but that does not mean anything to me. A lot of high Xmax woofers from your competitors have low efficiency. Your TRIO12, TRIO8, and SDX10 have an efficiency of 85 dB which is low efficiency. I am willing to spend the money on efficiency compared to spending the money on a marketing tactic that bases on wattage handling.

Another thing that will be nice is a dual 4 ohm voice coil version to provide more choices for hook up. A dual 2 ohm voice coil version is OK, but has the fewest choices for hook up. A dual 4 ohm version can be hooked up in series to provide an 8 ohm to benefit to hooking up two for an amplifier that is 4 ohm stable or up to four for a amplifier that is 2 ohm stable.
