Hi Wayne,
A couple of years ago I stumbled on your designs and you kindly sent me the plans for the 7pi corner horn when I suggested my lounge might be ok as a suitable location. I am in the UK so it has been necessary (cost wise) to collect parts locally rather than source them through you. I was happily collecting components for the 7pi when life got more than a bit busy and I have just come back to the idea of getting these built a few years later. Already purchased are the JBL 2226 woofers, the Eminence Delta 10 mids, the H290 horns and there I stopped.
I was a bit more clued up when I first started on my shopping list but not now. Please can you confirm that all drivers for the 7pi should be the 8 ohm version. My local supplier has four different types of the 8ohm B&C de250 drivers in limited numbers and I wondered if you could provide some guidance before I contact them. I think one is push fit, another spade terminal and a couple have 'tn' in the description. What would you normally suggest or supply ?
I was reading some of the more recent posts for information and looking at your replies to the "7pi plan and guidance request" post when I realised there were bigger 7pi woofers in the past and you were suggesting using his JBL 2242 drivers in 7pi-18 cabs or if no suitable corner location, a conventional box (attractive, 4pi-18 ?) as multisubs. I have two 18" Fane Colossus XB and one Colossus B which I think are not too dissimilar to the JBL as both are 99 db sensitive and designed for similar size ported cabinets. The XB specs are available on the web. I could fit in one corner sub and one or two conventional subs using the above. I hope you might supply plans if you agree that there is enough similarity.
Thanks Jeff
