upgrade: from Tham 15 to roar, ss15, paraflex?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   for the needs of a small setup I use 2 tham 15 and 2 rcf tt22a driven by 2 channels of a lab c48.4
the 750w satellites have 131 db declared, while the bass ones are the tham 15 with faital 15hp1060 driven with 1000w they should have 130db
To avoid bringing 4 subs, I would like to achieve better bass performance using the speakers I have, I don't know if it's a feeling due to the fact that more bass extension would be needed or I need more db in the same range.
However, I would like to do a new project also because I have the doubt that at high volumes the wood used, 20 mm conifer phenolic plywood, perhaps has losses, given that everyone finds the output of these subs monstrous.

what do you think of the various paraflex C, O that would be suitable for my woofers?
or the ss15?
the roar 15 is an old piano, it seems like a cross between paraflex and TH.

or should I change the type of upload, such as bandpass etc?

I have other unused woofers available: 15hp1030 which are the ferrite version of the 1060, 15nbx100 from b&c, and I also have 2 18 faital 18hp1010 - 4 ohm, they don't have an exaggerated bl, but I could see using them in a tham 18, the final would give 1200w/4ohm.. what do you think?

I could, in this case, make better use of the power by putting the power amplifier on 2 bridged channels and limiting the output :) it would become 2400x2 /8ohm
thank you ;)

	I was also thinking about the cubo sub and cubo extended both 15 and 18, does anyone have measurements and curves?

	Hi I think you're " over thinking" your problem? If you need a a small system then you won't get high SPL ? But like we did down here in Aus you could try some " barn doors" in front of your existing subs to give more directivity and more spl in front ? ... P.

	The Tham15 is quite efficient, not sure if you are going to find something that will outplay it? Are you happy with the frequency response? I have only ever heard a tham12 loaded with a faital driver, I was surprised by the output for the size, and the apparent extension! If the THAM15 is anything like it, it should be quite respectable? Your driver has a decent amount of linear displacement, are you sure you are using it to its full extent yet? Maybe a driver with a stronger motor would help? For example pd154/2 has less linear displacement, but has BL29, lower qts and is more sensitive at least on paper. That kind of driver would lend itself to some coercive EQ according to user crashpcs empirical findings.

	Agreed regarding efficiency, I’ve gone down the route of Tham 15’s and I’m very happy with them for my needs (I do have 6 and access to 2 more when I need them) I’ve used quite a few drivers and many different amps and as people say, they take quite a few drivers. However what that means is that between those that do work, I haven’t found big differences. Maybe one might go a little lower, one be a little louder but it’s never been enough for me to feel like replacing them. If you need lower, I think you’ll need a different box, if you need louder and feel like you’re on the edge of what you can safely give, you need more boxes. I find them an all round great bin for my needs, they are scalable in pairs, fours, sixes or eights. They don’t drop as low as I’d like but hey, what it does, I think they do well. What I have noticed is they can be pretty picky with how they’re placed in a space and often have to move them once or twice to get optimum results but as they’re pretty light this isn’t a problem. Maybe one option is to look at adding a single sub box, maybe an X1, there may be plenty of other options as well but it could take some load from the Thams and add the missing weight.
	blah blah blah blah blah......
