Don't forget the Pyle is an 8 ohm driver. So it will see only have the power of the ND140 for any given amp. That whittles away at it's sensitivity ... -

A quick run of WinISD shows the -8 will do 50 Hz in ~3.5 L. The only issue is that both versions unload very, very quickly past the 4 mm xmax with any...Last edited by Millstonemike; Yesterday, 05:06 PM.Leave a comment:

Would not the TCP115-8 suffice (they're in stock). I haven't modeled them them in WinISD, but PE's spec.'s (from Bassbox Pro) indicate the -8 will go...Leave a comment:

It really depends on your application. I'd go with the 48 V Meanwell for 8 ohm speakers, perhaps the buyout for 4 ohms. But if you have monster 4 ohms...Leave a comment:

No, that's not the PCB in the BT2.1. Both Tom and I have had the BT2.1 open and the BT2.1 PCB is very different. And I agree with Tom's thinking on the...Leave a comment:

The RS Duets crossed the RS225-8 (no "A") at ~ 1.5 KHz using a 4th order LP filter.Leave a comment:

Be aware that the eval board routes input signals directly to the TPA3255. But, the gain of the TPA3255 chip is fixed at 21.5 dB (~12x voltage gain)....Leave a comment:

The TPA3255 chip uses BTL mode and drives 4 ohms on each of it's two channels. It has an option to parallel the outputs...Leave a comment:

If my crude reverse calculation of the XOs is in the ballpark, the FE83 has a 1st order LP at ~1275 Hz. That would be Butterworth by default. The ND20FA...Leave a comment:

Any DVM will measure speaker level voltages below 1000 Hz on both the sub or L-R power outputs (the HF $5 DVMs are good to 10 Khz). Voltage measurements...Leave a comment:
