Questions about Pi Speakers
type: item
description: Hi Wayne, I have just discovered about Pi speakers 15 days ago. And I think Pi Speakers will be good for my future Music listening room & Home Theater room (actually both application in the same room). I designed acoustic treatment for my a hifi audio friend that has giant Exclusive speakers. Those speakers have big woofer and horn tweeters. In the listening test session, I can't believe how big the sound is. The kick drum of AC/DC Back in Black sound like a real drums in front of me. So I knew what is my ultimate sound is. It is a life-like sound system with high headroom and extremely good dynamic, slamming bass. I just can't go back to compact systems with small woofer anymore. They sound great and accurate but I miss the sound of big systems. I considered the options based on SEOS horn before, but after reading your comparison measurement, I forget it and decide that H290C is probably the best one I can find. After reading about Pi speakers, your papers, your absolutely wonderful articles I really believe I can trust Pi Speakers. The problem is my place is tooooooo far from US, the shipping cost for heavy drivers alone will cost me a totally new mid-end sound system... So I think about buying lightweight components like cross over and H290C horn. My questions are: 1. In each model 3Pi, 4Pi, you give us options to upgrade. However, does crossover (which I will buy from your store) have to modify anything to adapt to my upgrade (drivers) options? If I choose the stock woofer/tweeter or upgraded woofer/tweeter, is the crossover the same? 2. Where can I buy speaker plans? 3. I like your 3Pi Subwoofer but I don't know how to use it properly in a totally passive system (passive speaker, passive subwoofer) to maximize its ability regarding gain staging and equipments that need to connect to. I am using an 2.1 active system, and connect mains to subwoofers is dead easy. But in a passive system (I have not ever use any passive system), I don't know how. 4. If I want to m…

One of the first things I observed was that high-efficiency loudspeakers were preferable to speakers with lower efficiency. I'd say sensitivity it's second only to tonal balance in importance. Next would be directivity followed by distortion.

The SEOS horn is a pretty good device, but it is too short to provide adequate acoustic loading and that makes its response peaky. I realize that this isn't important to some waveguide enthusiasts, but for me, it's a pretty big deal. I think that to sacrifice acoustic loading for directivity is a bad move. Sure, we want uniform-directivity, but we don't want to have a peaky device just to gain constant-directivity. That's the lesson we learned from the the early CD horns.

description: Dear Wayne, Thank you A LOT for detailed reply! Recently I researched a little bit about Eminence drivers and find that recently they have some really good drivers with Neo magnet at the reasonable price. For example Deltallite 2512, 2510, 2515 and KappaLite 3015, 3012, 3015... Do you have any plan to add them as upgrade options for your existing design? I checked the specs of Delta 12LF and Deltalite 2512, they are not much far from each other. Can I use it as a low-cost upgrade from Delta 12LF? How about Kappalite 3015 as an upgrade option for Omega 15? Thank you very much. Edwards

description: The upgraded midwoofer for the three π speaker is a Definimax 4012HO and the upgraded woofer for the four π loudspeaker is the JBL 2226H. These were chosen for the excellent distortion-reducing properties afforded by the use of a flux-stabilizing shorting ring in the motor core. Magnet structures
