Gallo Classico Subwoofers


Anyone here have any experience with them?  I'm looking to buy two small subs to compliment my Aerial 5B speakers.  This will be strictly for music in a small room (office).  I already have a little REL T3 that just cannot play low enough (-6db@30hz).  I want something fast (musical) that will blend well with the little Aerials which drop off sharply around 70hz.  The Classico is available in a 10" which is -3db@19hz or a 12 which is -3db@16hz.  My understanding is that they are some sort of transmission line enclosure which I have no experience with.  Anyone have any advice on which model to choose or should I go with something else altogether?

I bought a pair of the ClS 12's just after Thanksgiving you wont touch their performance for the money, not even on the used market. They are a basic transmission line, and perform great,
very easy to integrate, and are seamless, fast and tight. No problem
keeping up with large ribbon speaker.

Only surprise for me was the necessary y adaptor, no one offers a
true audio grade, so  I made a pair out of pure silver, wbt ag on the sockets, and Aurial Thrills for the male RCA's, well worth the expense.     

So far, so good. Ended up with one between my speakers around 4' off front wall. The other is half way down left wall from my listening seat. Not sure this is where they will end up though. My only complaint is that the lowest X-over point is 50hz. Would be better off with a X-over point around 35-40hz in system. Well worth there asking price.
I hear you Tom on the crossover point, I like the crossover bypass
switch, allowing the addition of a external crossover, really flexible!

When mine showed up, made sure they worked, then tore them down, 1gal of acousti x  sound coat for both subs, 3 coats internally,
including the basket of the drivers, completely coated the amps with AVM, changed the fuses, eliminated the micro arcing with all of the internal mechanical connections, cones & shock pads, 75lbs of mass loading on the top of each sub,  couple of decent power chords. Modifications were not expensive, transformed them into giant killers, total cost well under 2k thanks Underwood Hifi!
