speaker shopping


I have a classe fifteen amp with parasound front end and am looking for speakers to go into a 12x22 room with 4 ft knee walls.

I've recommended these a couple of times around here... The very big problem is that its a kit.  I've been designing and building speakers for years. I've known and sat in front of countless speakers with their designers.  These would be hard to touch for under $6000 in production, but you'll need to finish them.
Jeff Bagby is the designer, he could easily work for any of the big names out there, these are smooth, detailed and will disappear.
Not too many on Agon would do these because of the labor and a bit of skill needed, but if you're up to it, these are an outstanding value.

I've looked at this kit many times, it sells out regularly, it'll be back in stock in a few days.  This kit is all Morel drivers.  Driver cost alone is $700 to $800 range...
Jeff did not use any impedance compensation on this kit, that means that it will stray upwards in impedance at certain frequencies, but it won't stray lower.  This is a protected Proprietary kit, they won't show schematics or curves without a purchase.  I have used the parts included, they are all great sounding.  I trust very few speaker designers, including some fairly well known manufactures.  Jeff is a solid designer, these will sing.
Hi cwright590, Thanks for the info, I took a look at these drivers. The good news is that the tweeter has a better impedance curve than most. The bad news is that both drivers need to be notched. and you would need some steep slopes and the woofer need Z-comp..  In the end, it could be very good, but it requires some crossover work. If you'd like, your welcome to pm me.  If not, I understand, I hope this helps, Tim




I'd wait on speakers until you give the Scan Speak a try,  I've looked them over, I'm sure that they are capable a singing....
Here is the basics of what I'd do to these...
I'm not sure if you are running a speaker program or not, but if so, plug this in:
Crossover, 12db L/R on the tweeter @ 2k, impedance at crossover point is 6.3 ohms.  You'll need to notch the tweeter 3db from 2k to 4k...
Ideally, you need a notch filter on the woofer, I worry about what phasing will do by crossing these within the notch without running these on a program, please check that out.  For now, i'd run
24db L/R on the woofer @ 2k, crossover on an impedance of 4.5 ohms,  you'll need zobel on the woofer for that crossover point to work.  You'll still be dealing with a slight peak in the woofer... without notching it, it won't go away.  I'd listen to these with a slight tow in, that will take care of it...
Another option would be to completely notch out the peaks in both drivers and cross between the notch at 4k... my experience says that the option that I laid out above will sound slightly better, but not much and with the 4k crossover, you could use a much simpler crossover approach.  6/12 butterworth with zobel on the woofer only...
I hope that this all makes sense, Tim
