which of these dayton subs are best for music? (1 Viewer)

[steve all]

hi, my choices are the heavy duty #295-130 or the #295-560 Quatro both, 15". the plate amp will be the #300-804 model. mostly interested in accuracy, for music. thanks for any help, steve all

Well, the Quatro series driver will take better advantage of the amp's power since it's a 4 ohm driver, but whether or not either of these drivers will be able to handle the power from this amp depends totally on what type of alignment you choose for them. What size enclosure are you planning on using? Will it be sealed or ported? If ported, to what frequency do you plan on tuning the enclosure?

hi Brian, i ran them both in WINISD PRO. the quatro, came up with 7cu. ft tuned to 20.49hz and the 295-130 8 ohm, came up to 5 cu. ft tuned to 22hz both vented using QB3 QUASI-BUTTERWORTH alignment 4" vent. the amp puts 150 watts into 8 ohms, and 240 watts into 4 ohms. hope this helps and thanks, steve all

I like the looks of the Quatro design more than the Dayton II woofer since it extends lower, but both will end up having potential problems due to their low Xmax values. You'll exceed Xmax below 37Hz with the Quatro and will exceed Xmax below 38Hz with the Series II woofer. Granted, you only exceed Xmax by a few mm with either design but you still cutting things close. Anytime you exceed Xmax you run into distortion issues. If it were me, I'd build a 175L enclosure tuned to 17.5Hz with 64oz. of polyfill inside and use the Dayton DVC 15" driver instead. I've built 3 of these so far and have had great feedback. One was for my dad and the other 2 were for a customer's HT setup. I know it's basically double the money of these drivers, but it's also roughly double the output capabilities, too.
