I've searched through past posts to see what speakers might be suitable for the Bottlehead Paramours, and I was very interested to read that these amps could be used with the JBL driver in the 10-pi. I really like the idea of building the folded horns, even though the Theater 4's would be more practical and sensible, and fit in my living room. Perhaps if I could see the plans for the 10-pi I could get over this dangerous infatuation - thanks

Hi Wayne, I've also been studying the information on the 10PI on your website. Comparing the dimensions of the 4PI and 10PI, it seem like the 10PI is just a 4PI with the woofer facing the other way and fitted with a horn. Can you confirm if this is true? Have you, or any of your customers ever try convert a 4PI into a 10PI, provided tweeter attenuation is adjusted? Gar.

The 10 pi ported cabinet alignments (given by pialign) without the attached horn are outstanding for midbass response. I've never actually used the program specifically to design a midbass enclosure, but designs that I've made and optimized on my own for midbass driver cabinets usually fall very close to the specs that pialign gives. The result is a very potent midbass and upper bass speaker. Strapping on the horn helps augment the bottom end. Adam

Paramours don't seem to be as sensitive to the woofer's impedance fluxuations in the resonance region as do some other SET amplifiers.
So you have a few more loudspeaker options than I would recommend for other SET amp owners. Four examples that I really like are the Theater Series three π, the Theater Series six π, the Stage Series four π and the Stage Series seven π. I haven't tried the Audiophile Series seven π-18, but I'll bet it is an absolute killer on a well-built pair of Paramours too.The Professional Series four π, seven π and ten π loudspeakers aren't the best suited for SET amps, but they aren't the worst either. Their efficiency is good, and their impedance curve is acceptable, but it's a close call. Some SET amps sound a bit anemic on them, but the Paramours work great with each of them. One thing about the ten π's - If you have two good corners, I think you'd be happier with seven π cornerhorns instead. If you have only one good corner or something like that, the ten's are great along walls where seven π's could not be used. But unless the room is huge, the speakers are so large they are intrusive.
