I'd probably go plate amp this time so that I can integrate it in the enclosure rather than making it a passive sub again. That'll be another $800 totalling to $2,900.
That's a great saving of course and if I would be comparing the F18 against it in terms of output the Dayton would come out on top. If I compare it against the FV18 however, the picture changes. The Rythmik loses out above 30Hz, but it does have more grunt below that. However that's hardly fair as I'm comparing ported versus sealed at that point.
The problem is that going ported with the Dayton I have no idea of what to expect as it has not been measured on data-bass. Also no idea if this will give me the articulate bass I'm looking for which I know I would get with an F18 but most likely also with the FV18. Going ported with the Dayton otoh may or may not result in too much bloat...
Definitely an option to consider though... Are there any other drivers that would come recommended?
The Dayton driver has excellent sound quality with very low distortion. I'd take an educated guess that it will have distortion just as low as the F18, and does it without servo. Servo is one way to achieve lower distortion, but excellent driver design is another. This is not a knock against Rythmik or their sound quality nor how they achieve it. Just saying, Rythmik with servo does not automatically make them have better sound quality or be more articulate than any and all other subs. The 18" drivers I just picked up, in 4 ft^3 sealed cabs handily outperform the F18...similar down low but a big lead up top. However, it is probably, arguably, one of the best all around 18" drivers made, and comes with a price.
The UM-18 is hard to beat from a value and sound quality standpoint. Whereas I can get a UM-18 for $325 or so, you have to spend around double to get a better driver. Will they be twice as good? Probably not. Again, it's just a very hard to beat value, and one could argue that you could put two of them in a small dual opposed cab and outperform a $600 driver in the same size cab in every way, top to bottom.
The question is, do you want a turn key sub with a warranty, limiters in place to keep the driver safe, etc? On the other hand, with DIY, once you have a couple of UM-18's in sealed cabs, you can easily change over to ported cabs if you ever chose to without buying entirely new subs...just new cabs. I'd take a look at the Crest Pro-lite 7.5 for amplification. If you want the value leader, the Inuke6000 dsp is the most bang for the buck...just swap in some Noctua fans for $30 or so for a silent setup. I guess its called the NX6000 now. It's the perfect amount of power for a pair of UM-18's, and excellent DSP capability.
The Dayton driver is $800???
It's a tough call.
