Old School Hertz 'Air' Mille Subwoofers

Is anyone here currently running infinate baffle using a Hertz Air Mille Free Air subwoofer ?

What kind of sound quality can I expect from one of these, perhaps the 15" model running infinate baffle in the trunk of my Skyline on 750w RMS ?

but...decent sound quality in the process ? running IB ?

These subs seemed to be spec'd for Free Air, Sealed and Ported in the manuals.....but are called HERTZ AIR MILLE, FREE AIR SUBWOOFER......

Atleast I wouldn't have to build a box for my current ML3000...lol....and I am sure that 750w RMS from my LRx5.1k would do fine with that 15" ML3800.

I think that sub IB will give you excellent results! I think the 750w might be a little wishfull in an ib configuration but just be carefull with it. I ran the 12 in a ported box (dont remember all the details but it was large) and it was absolutely amazing. The model below those (forget the models) were probably some of the worst sounding subs I have ever used (hsk line now dont know if it was hsk energy or what back then?). I dont remember if they made a 10" mille sub from that line and I could fit an adequate ported box in my center console (and I could find one) I would use one again in a heart beat. I dont think I would run one sealed though?

Low Xmax, high Fs (really high for a free-air 15), high inductance...meh. If you can look past the brand...big IF...there's lots of other subs which will be louder off the same power and play lower.

Bust out that WinISD and get to modeling :)

I paid just under $500 USD shipped express from Italy for a Brand New In Box Unit.

Could I have done it better and cheaper ? sure I could have. Would my OCD allow me to mix/match brands ?...lol...NOT A CHANCE ;)

To tell you the truth, I am not too worried, as these subs (Mille Air) have received nothing but praise world-wide for the last 5 years and if I am not happy with it, I still have my originally planned-to-use Mille ML3000 12" ready to go into a box.

I am willing to sacrifice a bit of SQ (by using the Mille Air) in order to have a trunk.....It's not like I will be competing with anyone. This is for my own enjoyment. Not someone elses.
