Acquired a set of 2311 horns, already had the 2308 diffusers, to compare to the 2397. My impression is that both are good but in different ways.. The 2311/2308 is livelier and seems to resolve...

I was recently loaned a pair of early Edgar salad bowls, a pair of JBL 2397 Smith horns, and a pair of 2405 in the hope that this would help me to understand what I like, and what works well in my...

Hi,
This is a three way system with currently a 2402 on top, 2440 on the mids. It is possible that in the future I will want to use a 2405 which is why I choose a cross-over point of 8kHz...

Thanks, Yggdrasil!

Just a little more background for anyone who might have some insight.. My listening position is about 3m (10 ft) from the speakers. The original set up prior to the arrival of...

Such as it is I think the best place to split the thread might be at #10. I didn't really intend to hijack the thread but effectively feel I have.. :D

What I am really trying to get at is what...

I'm learning something new everyday. :D I believe I currently lack the sophistication & experience to safely design one of these horns and get it made.. I noticed the treatment at the edge of the...

Yeah, I was aware of Orange County Speaker, unfortunately the round trip shipping charges from Boston, Ma. would be prohibitive for something the size and weight of a 2440 and I really wanted to find...

I stand corrected.. :D I have not seen, nor compared the phase plugs in the 2441 with the 2440. Thanks for setting the record straight as I was mis-informed. I did know about the diaphragms..

I seriously appreciate the assistance, perhaps we should start a new thread or perhaps a mod can move these posts to a new thread and let us know? I didn't intend to hijack the thread..

OT again:...

Thank you Peter, I am starting to look into this. Looks very interesting.. I am such a newbie at all of this and have a huge opportunity to get some custom horns built and want to make sure I make...

Yes, sometimes the journey is the most fun part. I've just embarked on a set of major system changes which at times can feel like a step backward or two, but should eventually result in even better...

Depending on what you mean by bass you could go with the subwoofer set up proposed or investigate the old Jensen Ultraflex (AKA Onken) which imho has the qualities of fast agile bass you are seeking...

My understanding from people who own both 2441 and 2440 is that the phase plugs between these two drivers have always been different. I own a pair of 2440 but have not seen a pair of 2441 apart.

A little OT: I'd be very interested in hearing more about the directional characteristics of conicals vs tractrix if you have any insights you'd like to share. Using Hornresp with the 350Hz design I...

That looks really great. :applaud:I look forward to reading your impressions of the end result. Real craftsmanship in action.

I'm messing around with Horn Resp and a couple of things are...

Hi Ben,
Checked out your blog, very nice work.. Like the conical you are currently working on.

That is quite the speaker project. I am continuously impressed by the workmanship I see on this forum.. Makes me feel like the amateur I am.. :D

Yeah I am crossing from the 2440 to a 2402 at 8kHz, so I am completely with you on the need to use this in a 3 way system. My set up sounds pretty smooth, so I am debating the wisdom of acquiring...

I'm looking at doing something similar for a pair of JBL 2440 w/2445J diaphragms I recently received as a gift. Or possibly a conical.. Cosmos I hear you have a number of good designs - anywhere I...

I thought the 2445J diaphragm was titanium? Perhaps changing to a Radian 1245-16 is an option?

I've heard a little bit about applying aquaplas, but don't know anyone who has done it. I'm running...

I have heard a system using RCA field coils, fun, but I think unless you are very well healed the money can be spent better elsewhere. If you have access to a decent machine shop perhaps you could...

Nice score.. The 2402/075 appear to be alnico, worth what you paid for the whole thing by themselves.

The standard X-O combination is generic, but fine for use with these drivers. I'm not...
