Wayne ... I am using P.audio P150 (JBL 2226 clone) in backloaded JBL Model 34 bass horns. They couldn't produce bass with a stiff wind. I would like to use the Model 34's for UB and the P150's in your Pro 7's. Assuming they will perform close to the JBL's, what is the bass extension I might get from them? Your Boxplot doesn't take into consideration corner placement if I read right. They will be driven by two 375 watt plate amps (OAudio) that has built in EQ so I can tweak if necessary. Plan is to use them for subwoofers only up to 60hz-80hz. If good idea will you send plans. I will certainly accept alternative ideas. Just for reference what will stacked Pro 7's do? The JBL Model 34 horns originally used JBL D130's. Can you recommend a driver that might work well considering they only need to go to 50hz or so? Can I get your mid and tweeter horns separate? Thanks, Zene
The midhorns are avilable as a flat pack kit, or you can build them yourself from the plans. The wooden tweeter horn is available separately, or you can use an Eminence H290. As for the seven π bass bin, it is slightly overdamped which works well for corner loading. You'll definitely get some room gain, so you don't want to overdo it by having an alignment like B4. With the 2226 in a seven π bass bin, you can expect nice clean bass down to 40Hz, with gradual rolloff below that.
Thanks, will you pop over plans for the Pro7 15 so I can see if will fit. Zene
Certainly. Please send me your E-Mail address and I'll send the plans right over.
Wayne ... I knew I forgot something. Da! zene@comcast.net
Wayne, can I trouble you for the mid plans, also? And, do I really need back wings if I use as subwoofer and cross low (
Midhorn plans are included. The angled panels in the back are really there for structural support, with the shape of the rear area being used as a positioning device to fit properly into the corner.
Appreciate your efforts for us acoustically challenged. Think I used that line before. Zene
