Your woofer choice will determine your final sensitivity. If 95db is close to your target efficiency you will have many choices, depending on your budget. A passive crossover with any 2Ae or 300b amp should be plenty of power. You could also choose to bi-amp with and an active crossover using a small tube amp an top and 10 to 20 watt solid state amp ( First Watt ? ) on the woofer. I prefer tubes for mid bass on up but that is my personal choice. You are always better off giving yourself a little extra headroom when it comes to amplifier power.

Hi and thank you very much indeed.
When you say " Your woofer choice will determine your final sensitivity " you are of course very right
In the excitement of my recent move to HE i had not time to think a little ... i am sincerely excited by the opportunity to use small amps of great sound. Finally i would say.
Instead of wasting time and energy and money trying to pushing a stubborn mule ...
That said yes ... maybe also less than 95dB
So i think that 10 good Watts should do the job
Nevertheless i would like much better a solid state option
Very very much more.
And possible integrated one ... to free me from preamps .. cables and other issues of matching components.
And passive xover even if i understand an active one could be better
I need to simplify my set up extremely.
Thanks a lot.
Kind regards,

Look on Audiogon under integrated amplifiers so you get an idea of what is available in your price range.
Hi and thanks a lot for the valuable suggestion
Main issue is active or passive xover ... this is the question.
I would much prefer the passive, one amp and that is all
But i have got opinions that makes me understand that the active solution is much much better ... actually it is THE solution.
It is possible to have very precise and sharp cuts
Maybe i am wrong but it must be much more popular in high quality systems
I could used just a very tiny amp for the compression driver
Even something like the old t-amp ... or similar
I have already one somewhere
The t-amp has big limits on the bass .. but for the range above could be jsut fine and with power to spare
And i have already one ...
I just need two PA speakers with decent woofers to use for the bass and as a stand for the compression drivers
Now if ony Pyle would answer ... why they did not mention the measurements conditions it is weird to me ...
Just say ... response measured at the open throat without horn ... and i will save on horns.
Thanks a lot.
Kind regards,

Active is only better if the active crossover is very good. If it is a cheap one it will ruin the sound far more than a decent passive crossover.
The only one that I had which was worthwhile was an Accuphase F25. I tried others, including the Bryston BP10 but only the Accuphase is relatively transparent and even it was worse in the end than a good passive xover.
You are treading into an area I think you lack the knowledge and skills to make a convincing sounding speaker and I fear you will end up blaming other things than the mess you made.
Hi and thanks again for the valuable advice
I thought the Bryston were quite good by the way
the question is than an active xover i can buy
A passive crossover i have to design and build myself. Big difference.
That could be end up in a real mess.
I would like to know people with HE speakers which solution they prefer.
Or which is the most common.
Moreover the active one by the way needs another amp. That is sure.
Kind regards,
