Big LS for little money?

Quick test: very dominant heights, OMG how loud but little to no bass despite Loudnesstaste and bass control + 12dB full blast. My pants flapping in front of the grid ... everything rattles in the room .... It sounds to my ears but unbalanced / hollow. The piezos are somewhat scratchy / unclean in very quiet passages. From low volume or more, this is just gone. However, this could also come from the old amplifier 20j of me. Put in the corners bring a loud, party-suitable overall sound. It is, however, at the size of a bass dish of 15 "38cm 22kg each box a faint idea of ​​bass. So open and daily.

+++ --- Wohooo loudly already at oldschool Pioneere Hifi amplifier with 2x 80 Watts RMS into 8 ohms
+++ Overall tone up weak bass on OK when the highs are abgessenkt
+++ Eyecatcher
+++ The performance offered / components / processing / considering only 99 euros "without" shipping = unbelievable!

- No Crossover -> only one Elko 3,3nf for all piezo tweeter 5x
- Hard
- Gross
- No insulation
- No 35mm flange device
- No extreme low bass (hard suspended TT)
- Is and remains ne gray Partybox which level to do without die over long period of time and useful sound

MOD:
After 1 hour, followed by installation of a coil + Elko rumtesten for the TT and insulation material:
Thus, it can nevertheless play "Bässer" and sounds more naturally, no more hollow piece. The tweeter could now even lower (eg coil resistance +.) But one can also simply wegregeln.

My conclusion: Big private - Party - speaker for pocket money. There is an enormous offer performance, worth every penny.
