Hey guys help me out here if you could - I'm looking to buy a set of alpine drivers as spares or swap ins for my dts, and have found a pair at a good price. They are called swr 12D2, but they have silver cones and large logo. All the ones I see listed have the black cones and small logo. Can these be used?

I think we're the demons.

The silver are the older models. They should still work, but not as advanced design. The silver cone models still float around for less $ but are obsolete. Supposedly this is when the lower SWS models got uprated and were so good they were better than the flagship SWR series. So the SWR was revamped again with improved motor design and the new black cone.

Alpines white paper is known to be conservative figures especially "sensitivity" efficiency figures. The most common one when some compare to the lab12 design.
The Alpine SWR sensitivity actually calculates just under 91dB/2.83V/1M. By the t/s parameters, sensitivity calculates out to 90.8dB/2.83V/1M.
In the same size box, the Alpine should be capable of providing at least 3dB more output given enough power. Xmax is 36mm. As they say, no replacement for displacement.

Brilliant! Exactly what I needed to know. I'll hold out for the black cones. Thanks!

Love the built-in approach! I wish I had known I was using DTS10s before building my room. That said, front wall works great for me.

My friend has couple of crown XLS 5000 amps which he is willing to trade with my pair of XPA-1's . But crown is rated at 5000W bridged. Will that damage the drivers? which is better option? I understand they are overkill, but I already have them and I bought XPA used .

(PS: I have two DTS10 kits - so need amps to power both)

Thanks

Mani, what amps did you end up using, and if you used the xpa-1 how did you like it?

Sorry for delayed response . I was not following this thread. I ended up using QSC 4050 and they provided more than enough power.

Does anyone know where I can find a crossover that will do a 10 Hz HP @ 24 dB/Butterworth for the DTS-10 sub? Most of the crossovers I have looked at stop at 20Hz.

Can use a dcx2496 and manipulate the filters to extend the HPF below 20.

How to extend the high pass filter below 20hz in DCX2496


A real cheap way to at least have something is a 6db/oct with a properly sized capacitor inline of the positive to either the amp or BFD1124p. For instance your using unbalanced rca from the receiver. Splice in a 0.47uF inline of the center lead as it plugs into your BFD1124 (30k ohm input impedance). This gives a 6db/oct slope at 11Hz.

Minidsp 2x4 will do that for you. I use Velodyne SMS-1s with mine.

I have the 88M upgrade (which is supposed to give you the 2x8), and it shows it going down to 10Hz, but a HP shelf will start at 10Hz. Since the display doesn't show anything lower I am worried it won't be doing anything lower. I guess I could set it up, and run REW before and after setting the 10Hz HP to see what it does.
