Has any one built the MTH 4654?
Any ideas if it will work with other drivers? More details on it here: http://hornplans.free.fr/mth4654.html Sims, quite well in comparison the the SBH

I have just contacted the designer for this, and he has confirmed that the eminence 3015lf has a very good responce in this, but has a limited input of 450watt. http://hornplans.free.fr/mth4654.html with the recommended RCF driver - 37Hz -3dB pour 1 caisson - 33Hz -3dB pour 4 caissons - 30Hz -3dB pour 8 caissons Looks very tempting for me Plot of 8 compared to 8 of startecs SBH Edited by JDCutta - 05 September 2010 at 11:43pm |

That is just another 15" TH and not a good one.
Note on TH construction. That brace in mouth is BAD. HR can not show you but it will effect the output noticeably. Read FurySub DIYAdui.com Also notice the unused space in design. For the 3015LF use any of the following FurySub - DIYAudio.com Apache Mk4 - here abouts SS15 - DIYAudio.com (single sheet ply!) I have 4 of the Apache's BTW- page 120 (?) on the SHOW your sound system pt 2. I have built TH Mini clones - which a few have since done. Also the 3015 really should be passed at 32-35 Hz depending on box and power input. |

make it so you can test WITHOUT the last brace.
Test, Brace, retest. Post results. And man your in Cali... should have went over to DIYAudio.com and got the SS15 plans. Or the others I mentioned. |

A lot of flippant remarks here.
At first glance I too thought was a lot of wasted space however... Look at the plots and the volume of the entire box then make a judgement against alternatives (the few in the same ball park). To load this with a emi driver - especially one rated at 450watts would be like loading a psycho with a jaffa cake. I think the designer's being extremely sound offering budget options but just look at what is possible and also think of the benifit of the hi-fi sound tapped horns offer. Tom |

It's 9 ply acx aruccoply made in chile, they call it a hardwood .
I'm not putting the brace in the mouth at all, I did do the rest of the Braces though. Not sure what driver I'm using , I have some 18's around here. Baffle is cut for 18 . |
