I've been lurking here for a long time and its finally time to build a new pair of speakers. The question is whether to go with something conventional, like the Ellis Audio 1801, or horns like the Pi's? I know these are two entirely different approaches, since the 1801's are extremely insensitive speakers and the Pi's are extremely sensitive. One constraint is that the speaker can't be more than 44" tall, because of where I'm going to place them, so the standard method of building the 7Pi's is out, even though I do have a corner available, so I guess I could make a 2-way version of the 7Pi's. I want to spend around $750 ideally, but I'm willing to go up to $1k. If I did go with the Pi's, there is also the question of active versus passive. I could buy the Behringer digital crossover, which would have a lot of nice features, like the ability to eq for my room, but would require a bit more setup. What would you do in my situation? Also, if I did go with the 1801's or the Pis now, I may still build the other farther in the future, since I have some NHT 1.5's I could upgrade with the 1801's. Thanks, Ian

When I was at the Mastering Lab in Hollywood I heard Doug Sax's horns, which are either 3 or 4 way, and they were spectacular. Some of the best speakers I've ever heard. I believe they were all vintage Altec horns and they were built into the walls. He said any speaker needed to be able to hit 120dB transient with reasonably low distortion in order to accurately reproduce live music. But I don't have any idea how close a Pi speaker would sound to that. But if someone in the Pasadena/LA area has Pi's, I would love to hear them I know what the standard box speaker is like, and I'm a bit tired of it, but I know the 1801 is at least a bit better than the average speaker. I was looking at Adrian's site and his horn setup looked very nice. I'm curious what the tradeoffs are of the 10" mid in the 7Pi versus the 6" Adrian uses? If I could fit a smaller mid horn under my 44" height limit, that would be great, or if I could mount the tweeter and mid coincidentally. Alternately, maybe I could build the mid into the woofer corner horn cabinet and that would save me some height? -Ian

Used JBL 2425's at Bill's, any used 2226's? [message #46984 is a reply to message #46980] |

There are a pair of used JBL 2425's(which he says are the same as the 2426's) for $200 on Bill Martinelli's website. Would it be worth buying these instead of the Eminence drivers, or are the Eminence drivers just about as good anyway? Also, does anyone have any used JBL 2226's? My only concern about not building the midhorn into the cabinet is that I'd have to completely rebuild the cabinet later to add the 10", due to my height constraint.

Ian, I suspect a lot depends on your room size,your listening habits and preferences. If you like to listen critically and place your greatest value on such audiophile traits as depth of soundstage, imaging, smoothness and detail the 1801's may be your best choice. On the other hand if you prefer to listen less critically and value dynamic range and sonic impact that will make you tap your toes the Pi's will suit you better. The 1801's are more likely to make you feel the performers are in the room with you, the Pi's are more likely to make you feel that you are in the venue with the performers. I am now experimenting using a Stage 4Pi setting on top of an Adire Rava subwoofer as a center channel for home theater and as a center speaker in a 3 speaker "stereo" played through my AV receiver. I have to say that this combination is pretty impressive. I think the Stage 4 Pi sounds better off the floor a bit. Using a subwoofer and crossing it over at 60 or 80hz makes a really dynamic full range speaker and is great fun to listen to. If I were going to make a stereo pair of floor standing speakers and had the room size and suitable location I would make a pair Pro 4Pi's with JBL drivers and a subwoofer such as the Adire Rava or Tempest, the Vmps, GR Research or PartExpress Titanic in one large cabinet with separate chambers, or two cabinets with matching veneer. The whole cabinet could be less than 44" tall. By putting the sub with the Pi's you get the Pi's off the ground about the right height, you can cross them over above 60hz if you want without worrying about being able to identify the bass as a distinct sound a part from the rest of the speakers, phase issues also don't exist. Using two subs may give you smoother bass and will certainly give you more of it to help the subs keep up with the dynamic range of the Pi's. Larry

I have a pair of 2226G's (4 ohm), my 8 ohm are gone already and I have (4) of the 2226J's which are in my 4648 cabinets. Just use a .35 mh coil and take 3db off the attenuation off the horn circuit. Don't know if this helps at all. Ron

For the price, I'd grab the jbl. I bought a pair of these off Bill M. also. As for your height limit, not only could you do your 2 way 7Pi, but also could do the non mid horn 3 way. It uses the same midrange driver for the mid, its just set in the front of the cabinet, below the tweeter.Russellc
