Need help selecting between two budget 10" drivers

[percy]

Dayton classic 10". 295-315 @ www.partsexpress.com

and

MCM 55-1945 @ www.mcminone.com

T/S parms for the 55-1945 are:-

Qms 3.6
Qes .35
Qts .35
Vas 110 lt
Fs 26hz
Mag Wt 35oz
Xmax 5.0mm
SPL 89db
Watts 70W, 105W peak

This is for a 1.3 cu.ft vented(but could be sealed if needed) enclosure for a 3-way.

There are a couple of projects using the Dayton but I cant find any information on the MCM. Not quite sure if its intended for subwoofer duty or driver(woofer) duty. The specs look good but I have no idea how it sounds or the frequency response or the build quality. Although the heavier magnet and higer Qms/lower Qes make it attractive.

Any inputs appreciated! Thanks!

Where's the TS for the Dayton?

If you want a sub thats good for ported use, the general concesus is that the lower Qts the better.

Using the good old FS/Qes you can determine a rough guide for suitability.

In this case 26(Fs)/ 0.35(Qes) = 74

What does 74 mean? Well any number under 50 is an excellent candidate for sealed application, a number over 100 is great for ported. Anything inbetween like this could be considered for either depending on requirements.

Personally I'd go with sealed or a TL but that's not to say that reflex isn't good when done well. Just my preference really.

The TS of the mcm dont add up. One or more of the qms, qes or qts is wrong. I have an email into mcm inquiring about that.

I'll probably try both (sealed/vented) and see what I like.

If the qes is correct for the MCM than the qts is .319

MCM
Closed - Box size = 1 cu. ft. F3 = 62 hz.
Ported - size = 1.7 cu. ft. F3 = 42.5 hz.

Dayton
Closed - Box size = 1.2 cu. ft. F3 = 53 hz.
Ported - size = 2.2 cu. ft. F3 = 30 hz.
