The narrow baffle design of the speaker will help with imaging but as Wayne says it will increase the baffle step a little. Will this speaker blow the doors off a 15" or 18", or horn loaded bass speaker? No, lets not be silly! It has very nice bass and surprised a lot of people who listened to them while at MAF.

I can assure you that not only is there no structural detriment to having the driver mounted in a narrow baffle. It is actually more ridged and structurally sound than a wider baffle. The driver is not just attached to a front baffle, it is also attached into the side panels of the cabinet. There is ample unequal bracing in the cabinet which makes a very ridged box with no unwanted box excited resonance.

I find the Arezzo 12 to be tube friendly with the tube amps I have used. I have not tried a 2A3 or a 45 amp. They work great with a Dyna 35, higher wattage mono blocks and they were running almost the entire MAF show with a Audio Note 8 watt 300B amp. In fact, They sounded so good with the Audio Note 300B, I'll be picking that amp up in a few weeks because I bought it!

If your looking to build a speaker or have a finished speaker built for a smaller room or where space is an issue. I suggest you try a Pi Theater 3 or an Arezzo 12. The have two things that make them a tweakers pleaser. They are small and compact for a high efficiency speaker, fitting to many decor and very WAF. Second, Although perfectly fine as they are. By adding a well thought out subwoofer and supertweeter. You essentially have a perfect 4 way design with minimal extra labor and crossover compliments.

Hope this helped, Doctor Epstein says I write too much. just a speaker junkie at heart.
