I need to build subwoofers that are easy to carry, unfortunately I am just moving them, I have to use them under a system that has 2 speakers per side, very efficient with 106db full range each. I currently have 6 tham 15s loaded with 15hp1030 of faital, the bass is a bit low compared to the speakers, the idea could have been to add another tham or two other thames, but that would also involve bringing another power amp with rack.
The idea was to remake the 6 basses with a better design, but let it not be huge, I have seen the paraflex and they are really nice, but I don't know how much more efficient they are than the tham.
I accept advice :) thanks Edited by Angelow - 26 January 2022 at 12:01pm |

6 Tham15 with those drivers should do some damage, have you set them up to work with the tops, phase, X over etc? I wonder if you are getting some cancellations around the X over point? Or are your issues lower than that, the Thams don't go too low, 50Hz and fall off quickly below that...
Thanks,

Dulux is right.....More information needed....
What exactly are your tops? What amps do you use? |

i use only one original lab gruppen fp14000, I have calibrated the limiter of the xta so as to never go to red, the parameters are automatic
the basses, 3 per side, under two full range speakers, cut at 100hz, fall behind especially on house music, tekno etc., it is as if they were not based

Also, probably all paraflex cabinets are significantly largen than the tham 15..
If you don't want to go much bigger than thams but deeper, BR is probably the answer.

Angelow, what are your tops?
You are doing something very wrongly....... With that amp and 3 faital 15" with 12 mm xmax there should be enough bass...... Maybe polarity probems somewhere? Is your speaker wiring all in correct polarity? Edited by bob4 - 26 January 2022 at 2:35pm |

You say your tops are 106db/w @ 1 meter, thams are about 100db/w @ 1 meter so for every 1 watt of power you put into your tops you will need 4watts on the thams to match the output of the tops. |

Three thams per side though, so should be more like 104 dB at least?

the top are resolution 2 mark 2 funktion one, but the kick is modded by custom b&c
the gain of the kick is + 7 db (instead of + 8db) because it has more efficiency than one db, of the original, and the limiter is + 2 db more, in practice it manages almost double the power more than the original, come 1000w limited not to red from the final for single 15. so the mid-high part which is very efficient aligns better with the kick Edited by Angelow - 26 January 2022 at 3:23pm |

HD15 would go louder and also a little bit lower than THAM15, especially with 3 pieces per side. If you look at the graphs, the tham15 has a steeper rolloff, and is down to 85dB at 30 Hz, while the HD15 is still at 90-91 dB, and at 40 Hz the HD15 is also 3-4 dB louder. In the higher bass register the HD15 peaks arpumd 107-108 dB!! A lot more than the THAM15. HD15 is also a little bit smaller than THAM. I used to have four with Kappa15LF. Your faitals should be louder. Or you could do single or double 15" bass reflex, maybe add one 15" per side to have two doubles per side...... |
