I have tried quite a few different Dayton exciters for various applications. I picked these up for a medium-sized DML speaker project using 3mm Birch Ply, after the 8 ohm flat pack drivers I first tried proved to be inadequate. They hit the specs just right for RMS power requirements at 4 ohms with the amp I'm using, and compared to models with similar specs they had the best looking FR per Dayton's spec sheets, and the largest coils. The spring loaded terminals were a definite bonus.I have pushed them hard at a clean, bench-confirmed 35 watts RMS and they sound fantastic. Fair warning - don't expect or try to get massive bass from these (or any exciter in most applications). If you try to push them hard with a low frequency cutoff much below 100hz you will quickly overdrive/overheat the coils and spiders and you'll end up with blown or dead unit. I have a 20hz subsonic filter on them and they're crossed over at around 100hz with a 24db slope. These are low-mass, full range drivers and you're already asking a lot from them at high volumes. Relieving them of the low end strain makes these work 100 better in the rest of the range (And if you're building DMLs you're not going to find a substrate that gives good low end a well as a warm high end anyway). These are not magic. If you want big bass you will need to put a high pass filter on them and run them with a dedicated woofer or sub. If you're going to run them completely full range just be careful not to get too liberal with the bass knob or crank them too loud and you'll be fine.In their happy FR range, and with proper power and appropriate host surface/damping they sound excellent and will easily crank above shouting levels in a medium living room with no distortion.Properly driven they sound clean and open, with good dynamism and rendering. I have run them with everything from delicate jazz and blues vocals, to pop/rock/electronic. They get even better and brighter if you can throw some EQ at them to mitigate the dip at around 11k and the sharp rolloff above 16k, and again, to roll out the low frequencies that will want to burn them up. I am really happy with these overall and would recommend them.
