Hp used in bass reflex cabinet of about 160L, designed to get very low frequency, 15k200 is perfect for a box of very good sound quality and a relatively high power. If you are facing the powerful sonoristion rather take a 46cm because HP provides the "only" 300WRMS. I use it with an R300
receiver that heats a lot, but keeps a pretty good dynamic.
The HP is filtered at 120Hz with a slope of 24dB/octave on my box and the sound is deep and dynamic, for a 38cm is very good.
I use it for 2 years and has a sound system worthy of the big business, the less power.
To use a home theater or small party is perfect.
