Hi Romy…and fellow audio nutters.
 
I’ve bitten the bullet, and shifted from BLH to front-loaded. Yes, I was an idiot, a moron for not doing this sooner.
 
My project is ‘humble’ by Romy’s standard…but I feel it meets the following objectives I have set: 
  
1) A 4 or 5 way horn system, with all speakers being front loaded
2) Costs contained as best as possible
3) Cabinets that enable me to have some DIY input
4) Use of compression driver for the 500-5,000 range
5) Retain the use of my valve amp (2A3 Push Pull) where possible, but may go active down the track
 
System layout:
 
Sub is Bill Fitzmaurice Tuba (Low Profile) running up to 90-100Hz. I have the O-Audio 300 watt BASH amp for this. Quite a big sound.
 
Mid bass is DIY based on a John Inlow drawing, features B&C 12-inch driver (PE32), 101dB, low qts of 0.18. I will run this up to 500/550Hz. See pics of the early stages of this build.
 
Mid tractrix horn is Stereolabs stone composite 250Hz, using Selenium D405 driver. These have been ordered from Germany….mid blue in colour. (Are you cringing because of these drivers? Well, it's a start. Would I like S2's, ALE, GOTO, TAD...? For sure.)
 
HF is Sterolabs tractrix 1,000Hz horn, using Selenium D220TI, running from 5,000Hz.
 
Having recently built a two-way ‘Klipsch’ “Cornscala”  (Bob Crites design, using Faital Pro 1.4 inch driver and Eminence 15-inch woofer), I decided to use Bob to build some custom xovers.
 
My amp is a new Weston Acoustics 2A3 push-pull (similar here), with approx. 9-10 watts RMS/side (x2 2A3’s per channel). I love the amp…so I wish to retain this for driving the horns (except sub).
 
Source is no frills CD/DVD player with DIYEDEN DAC. Simple but quality silver cables throughout…including all silver speaker wiring, but silver over copper for interconnects.
 
Music choice is blues, jazz, funk…not a lot of classical.
 
Kind regards 
Andrew
