Hi all,
I perused the archives in this site, but I am a little confused, in part because there is too much to read!
I currently use a 2 way system, based on a LE15A in a 5.5 cuft box as per JBL guidelines, this is crossed to LE85 at 800Hz. The problem is that the LE15A are showing signs of aging, and have strange impedance curves (both have lost their impedance peak at resonance frequency...). The system sounds good to my ears (I can't compare it with anything close to where I live), but it bothers me a lot.
To adress this, and also because I like woodworking as much as hifi, I would like to design a new 'bottom end' to my system, with some limitations:
I read a lot about 2235's, but they would be borderline to what I want (higher box volume for housing a pair to have the right efficiency).
- No less than at least 97 db efficient (I use a 2A3 triode amp, and that one is definitely not going!)
- Max volume if possible inthe 6-7 cuft range (I have a small room)
- Could be based on single or double woofers, 12 or 15", I have no preference
- lower frequency as low as possible (30 Hz or lower? would like to avoid subwoof - again problem of a small room that needs to keep some empty volume for me and the rest of my stuff!)
Any other suggestions to make?
Thanks a lot for the help, I realize I still have a lot to learn, but then, I only started this way 2 yrs ago!
Cheers,
